MAPublisher 10.3 Released

We’re excited to announce the release of MAPublisher 10.3 for Adobe Illustrator. We’ve listened to your feedback and worked closely with our users to build features to improve map design and productivity. Stay tuned for more blog posts and other resources that go deeper into some of the new features. For now, here’s an overview:

MAPublisher 10.3

This update contains new features and performance improvements as well as fixes for reported issues. Some highlights are summarized below, for the full release notes see below.

Compatible with Adobe Illustrator CC 2019. We’re committed to providing the best GIS and cartography tools for building great quality maps in Adobe Illustrator. Improvements to our user interface to support high-resolution monitors, and this release is fully compatible with the latest Adobe Illustrator CC 2019 on both Windows (32-bit and 64-bit) and Mac.

Create Elevation Profile charts. An often-requested feature from our users, elevation data for points along a selected path can now be collected and displayed as an elevation profile in a highly customizable chart. The data is downloaded in real-time from a server (internet connection is required), which can then be customized to your liking using the available settings. Frequently used settings can even be saved for future use.

View data distribution when batch generating rules in MAP Themes and MAP LabelPro. When selecting a data classification in MAP Themes or MAP LabelPro, you now have the ability to see how it affects the data distribution in an interactive histogram and chart. Histograms are a great way to visualize continuous data in intervals and useful for large sets of data points.

Improved attribute capabilities in ‘Join’ tools. We have added many attribute management improvements to MAPublisher Join tools (Join Areas, Join Points, and Join Lines). You can now better manage how attributes are handled during a Join process, including the ability to calculate new attributes. We also added additional operations to help you better sort and calculate statistics from attributes.

MAPublisher 10.3 Release Notes

  • Compatible with Adobe Illustrator CC 2019
  • Create Elevation Profile charts
  • View data distribution when batch generating rules in MAP Themes and MAP LabelPro
  • Improved attribute capabilities in ‘Join’ tools
  • User interface and usability enhancements

 

Carto-Jargon 201: Cartography Terms Defined

In a previous blog post, we defined a few common cartography terms that you might be likely to encounter while using MAPublisher and Geographic Imager; however, that was just the tip of the iceberg when it comes to cartography and GIS jargon. Here, in no particular order, are several additional terms used by cartographers, GIS professionals and people who work with spatial imagery.

Topology

Topology is a key principle in GIS for data management and integrity, ensuring the data quality of spatial relationships is maintained. In general, a topological data model defines how spatial objects (point, line, and area features) are represented, and defines and enforces data integrity rules (for example, there should be no gaps between polygons).

Azimuth

The horizontal angle, measured in degrees, between a baseline drawn from a center point and another line drawn from the same point. Normally, the baseline points true north and the angle is measured clockwise from the baseline.

Neatline

All 2-dimensionally rendered maps have to compromise somewhat on accuracy, even if only just a little by moving or scaling features to improve readability. However, the neatline is never adjusted, making it the most accurate element on a map.

The neatline is the border defining the extent of geographic data on a map and separating the body of the map from the map margin. It demarcates map units such as meridians and parallels, and depending on the map projection and the units selected, the neatline may not have 90-degree corners.  

Geodatabase

A Geodatabase, a database or file structure used primarily to store, query, and manipulate spatial data, stores geometry, a spatial reference system, attributes, and behavioral rules for data. An advantage of geodatabases over shapefiles is that various types of geographic datasets can be collected within a geodatabase, including feature classes, attribute tables, raster datasets, network datasets, topologies, and many others.

Geoprocessing

Geoprocessing is an operation used to manipulate a GIS data resulting in a new set of data. Common geoprocessing operations include geographic feature overlay, feature selection and analysis, topology processing, raster processing, and data conversion. Geoprocessing allows for the definition, management, and analysis of information used to make decisions based on patterns within the GIS data.

Shapefile

An Esri Shapefile is a vector data storage format for storing the location, shape, and attributes of geographic features. A shapefile is stored as a set of related files and contains one feature class. An alternative to using shapefiles to store GIS data is a geodatabase, however, shapefiles have some advantages in terms of relative simplicity and wide-ranging compatibility with many applications. Related files contain additional information that is read by the shapefile when opening/importing in GIS applications, as long as these related files have the same name and reside in the same directory – the *.dbf (database) file contains attribute information, and the *.prj (projection) file contains coordinate system information. Shapefiles also have limitations such as the inability to support raster files, and large file sizes.

Buffer

A zone around a map feature measured in units of distance or time is called a buffer. Buffers are useful for proximity analysis.

Geodesy

Geodesy is the science concerned with the measurement and mathematical description of the size and shape of the earth and its gravitational fields. Geodesy includes the large-scale, extended surveys for determining positions and elevations of points, in which the size and shape of the earth must be taken into account to achieve accuracy.

Vector vs Raster

The terms vector and raster are encountered often in cartography though they are not often defined. In a nutshell,

Raster data is made up of pixels (sometimes referred to as grid cells). Each pixel can have a range of values used to represent data points. For example, in a satellite image, every pixel has a red, green and blue value.  

Vector data is not made up of a grid of pixels. Instead, vector graphics are comprised of vertices and paths where the vertices are x,y coordinates. In GIS systems, they are a latitude and longitude with a spatial reference frame.

Mosaic

A Mosaic is a single raster dataset composed of two or more merged raster datasets—for example, one image can be created by assembling multiple aerial photographs whose edges usually have been torn or cut selectively and matched to the imagery on adjoining images to form a continuous representation of a portion of the Earth’s surface.

Orthorectification

The process of correcting the geometry of an image so that it appears as though each pixel were acquired from directly overhead. Orthorectification is used to correct terrain distortion in aerial or satellite imagery.

Paper Maps and Digital Maps Go Together Like…

It’s no secret that we believe digital is the future of maps because of the many advantages that digital maps and mobile map readers offer. But we also recognize that there is still and always will be demand for paper maps. They go together like peanut butter and jelly, pizza and beer or fish and chips. In today’s digital marketplace, the trick will be for map publishers find ways to serve up these tasty combinations to map consumers in a commercially viable way.

While this seems trivial, in fact, there are challenges for publishers to efficiently provide maps in both paper and digital formats. For most established map publishers, the paper distribution channel is well characterized. With the right relationships, publishers can get their maps onto the market through websites, brick-and-mortar retail stores, at events and through other business partnerships. On the other hand, selling digital maps requires an e-commerce platform capable of handling digital products and an application on which to view and use the maps effectively.

To address the challenge, we have partnered with print on demand and publisher MapSherpa.
While our vision is to have all of your maps on your phone or tablet, theirs is to have maps in your pocket, or on your wall. Together we can make both of those scenarios a reality.

Our joint pilot project will allow map consumers to easily get maps in both digital and printed formats. Now, when view selected maps in the Avenza Map Store you’ll have the option to also purchase a paper copy in a variety of sizes, and printed on a variety of different materials from MapSherpa’s map store, MapTrove. Find one of the selected maps on the MapSherpa site, in paper format, and choose to purchase the digital version for use on your mobile device from the Avenza Map Store.

We see this as a model for the future of map publishing and distribution, and a winning solution for publishers and consumers alike.

You can find NOAA Charts and National Geographic maps in the Avenza Map Store,  available to download and print.

Cartographer Chronicles: Alison DeGraff Ollivierre

Alison DeGraff Ollivierre caught the geo/carto-bug from an introductory geography course in her first semester at Middlebury College, quickly realizing that the discipline was the perfect combination of her diverse interests in global affairs, conservation, history, and sociology. Now a cartographer at National Geographic Maps, Ollivierre works on the Trails Illustrated topographic outdoor recreation map products from an office in Colorado, making it easy for her to always be planning her next hike or trip to a National Park.

Ollivierre began her professional career as a Geography Intern at National Geographic in 2011, working with NatGeo Live and the Giant Traveling Maps. During her internship, she had the opportunity to make maps for a few NatGeo Explorer lectures and Giant Traveling Map fact cards, but what really stuck with her was how the incredible breadth of geography was used every day at NatGeo (and meeting Sylvia Earle—she thought that was pretty cool!). Since then she has gone on to win multiple awards for her cartography and was recently recognized by xyHt Magazine as a 40 Under 40 Remarkable Geospatial Professional for 2018.

 

As a certified GIS Professional, with a master’s degree in Geoinformatics from the University of the West Indies, Ollivierre knows geospatial data and how to handle it but also understands that—while the data is important—there is more that goes into making a good map than just the data. ‘I believe strongly in the importance of great design.’ explains Ollivierre. ‘It has the power to make geospatial data more engaging, interesting, and accessible to its audience.’

Ollivierre started using MAPublisher—a cartography plug-in for Adobe Illustrator—in 2016 when she returned to work at NatGeo after facilitating a participatory mapping project in the Eastern Caribbean, working as a cartographer and GIS specialist in Maine, and conducting freelance cartographic work for organizations across the globe. ‘I had played briefly around with a trial version of MAPublisher before that and heard a lot of great things about the software, so I was excited to learn how to use it at NatGeo Maps.’ says Ollivierre. ‘We complete 99% of our daily tasks in Illustrator + MAPublisher so its power is clearly evident in our workflow.’

Making quality maps that bring to life complex geospatial data requires a mix of science, art, and specialized tools to get it right. ‘I love the process of turning raw data into a map that clearly (and attractively!) gets its point across.’ says Ollivierre. ‘For me, MAPublisher is the obvious choice to bridge that gap between GIS and cartography.’

MAPublisher 10.2 Released

We’re excited to announce the release of MAPublisher 10.2 for Adobe Illustrator. The MAPublisher product team has been working closely with our customers to build these features to improve map design productivity.

MAPublisher 10.2

This update contains new features and performance improvements as well as fixes for reported issues. Some highlights are mentioned below, for the full release notes see below.

Filter layers and attributes with expressions on import. This feature that has been requested by many users in the past and we’re happy to say it’s finally here! While filtering attributes and geometry has been available since MAPublisher 10.0, the ability to filter specific layers and attributes using an expression was not available until now. This let’s you fine-tune your layer and attribute filter to only include (or exclude) specific data at the attribute value level. This improves Adobe Illustrator performance by reducing the number of map features and attributes being imported.  The Filter Geometry feature has been renamed Spatial Filter and it retains the same functionality. In addition, these filtering and simplification tools reside together in an improved user interface.

Simplify complex art on import. Another new import feature that reduces the amount of data is Simplification. It allows for the simplification or generalization of vector line and area data during data import instead of after. Using simplification during import reduces the number of map features and attributes being imported and improves overall performance. Simplification can be applied to all art together or applied separately to lines or areas and use either the Douglas-Peucker or Visvalingam-Whyatt method for removing nodes and vertices.

New support for WFS 2.0, AutoCAD 2018, and OGR formats. Several new formats are supported and updated in MAPublisher 10.2. The WFS 2.0 specification improves on a number of functionalities including response paging. More than 1,000 features can be loaded from a WFS server now. The AutoCAD 2018 format allows you to import and export version 22.0 DXF, DWG and DGN files. Read and write capabilities have been improved by updating OGR import formats (GML and PostGIS) and OGR export formats (GML and GeoJSON).

Overprint option for MAP Legend art. Overprint is essential in print production and reduces unsightly edges that could appear if printing plates are not perfectly aligned. MAPublisher generated art from Scale Bar, Grids and Graticules, and MAP Theme legends now have an overprint setting to ensure that art can be maintained as MAPublisher objects without having to expand art as separate objects, strokes, and fills.

MAPublisher 10.2 Release Notes

  • Filter layers and attributes with expressions on import
  • Simplify complex art on import
  • Import support for WFS 2.0 and AutoCAD 2018
  • Export support for GeoJSON and AutoCAD 2018
  • Introduces MAPublisher with a Simplified Chinese interface option
  • User interface and usability enhancements

 

Cartographer Chronicles: Mirian Isabel Say

Cartographer Chronicles - Mirian Isabel Say

Brazilian-based cartographer, Mirian Isabel Say, has two passions: making maps and traveling. Lucky enough to live in a large, diverse, and beautiful country as Brazil, she has extensively traveled through it to gain inspiration for personal growth and to find influences for her map designs. As an idealist, Mirian considers maps as works of art, not merely used to perform a singular function. Especially in a natural resource-rich country like Brazil, she believes that maps can help change the lives of its users, transcending the use of maps from a purely commercial purpose to a purpose that is appreciated and acknowledged.

For Mirian, the map design process is a huge personal journey, and having the right tools can be the difference between a published map and a map left unfinished on the computer. When Mirian began her cartography career in 1992, her choice of existing graphic design software was limited and didn’t include suitable tools specific to mapping. Even as the software improved, it didn’t support any of the commonly used geographic data file formats and she was limited to importing data that was not spatially referenced. For example, to accurately create a map scale by hand is very complicated—as any well-trained cartographer knows—and the functionality to do it digitally wasn’t available. Exporting to other cartography formats was not feasible since maps were not georeferenced. Symbols and labels were placed individually, often taking many hours of labour.

By 2004, graphic design and GIS software had become more advanced. Mirian learned about MAPublisher in-person at a GIS and mapping trade show and immediately liked how the many cartography and GIS tools were seamlessly integrated into Adobe Illustrator. She believed she finally found a cartography product that would be an all-in solution. When she returned home, she continued working in her existing graphic design environment, but continued to experience the many shortfalls of it. After some careful planning, she decided to take the leap and jump in headfirst to acquire MAPublisher and Adobe Illustrator.

Any major changes to a workflow including one that involves new software can be difficult at the beginning. Mirian began to adapt from her older graphic design software and learned the new MAPublisher toolsets through Avenza resources and working with the Avenza Support team directly with questions about workflows and best practices. “My type of work is not very common in Brazil and there are few engineers and cartographers who do it. Many years ago, I received professional critiques that my maps were beautiful but not accurate enough. Today, I’m very glad to say that I can create maps just as beautifully and more importantly keep them accurate.”

Vulnerabilidade      SJDR

Mirian’s style of mapping is an immersive experience. When hired to produce indigenous and environmental maps for the Brazilian state of Acre government, she researched the region’s geography, read about its natural resources, and made a trip to visit to explore the culture, people, and food. She says she hopes that others can also see the human side of geographic space as she portrays it in her maps and that maps can provide not just information, but social change. She believes that her connection to and experiences of places make her a better cartographer. When she created the official tourism map for the City of Rio de Janeiro, her home city, she wanted to be “in the present” and decided to explore areas of the city intimately by foot to visit museums, beaches, and landmarks. The City also helped her understand the scale of the area by helicopter – a definite highlight in her career. The result was an appreciation of the city’s colour palette expressed on her map. “The sea was light blue, the green forests were intense, and the rock formations were magnificent. Rio de Janeiro is a very sunny and cheerful city so I used cheerful yellowish-green colors.”

 

Mirian continues to produce maps for many clients and has had her maps featured in several publications. She has also taught several post-graduate cartography courses at universities and lectures on cartography techniques and the importance of using the best cartography tools available.

Carto-Jargon 101: Cartography Terms Defined

The field of cartography is filled with jargon and terminology that can pose a challenge for newcomers learning to use mapping software such as MAPublisher to make beautiful maps, and those who don’t have a formal background in cartography. It also doesn’t make it easier when different software packages have their own variations on certain terms. To help the cause, we have compiled a short list of common cartography terms or “carto-jargon” that you may encounter while using MAPublisher or Geographic Imager.

Basemap

A basemap is a background image which can include aerial imagery, topography, terrain and streets and other fundamental layers and is used as a starting point to create a new map. The basemap is georeferenced and is usually the most accurate source of spatial information within the data system that makes up the finished map. Additional layers of data such as labels, symbols and paths are then added to the basemap to create the final product.  

Feature

Any real-world object that is represented on a map is a feature. Features can encompass large areas of a map, such as bodies of water and mountain ranges, or they can be discreet objects like parking areas, public washrooms or fire hydrants.

Attribute

Attribute data is information about spatial features and is stored in tables. It is also the information that specifies the appearance and labeling of features on a map. For example, the graphic attributes of a river might include the thickness of the line, line length, color, and the name used for labeling.

Control Point

A control point is a location on the map with known pixel (x,y) coordinates. Control points are used in georeferencing to allow for extrapolation of the relative location of other points whose exact coordinates may not be known.

Coordinate System

A coordinate system is a reference system used to represent the locations of geographic features on a map. It provides the basis for identifying locations on the earth’s surface. There are thousands of different coordinate systems, most of which are limited in use to highly specialized purposes.

Projection

The earth is not flat and so imagining that it is for the purpose of putting it on a 2-dimensional map results in some distortion. A projection is a method by which the curved surface of the earth is portrayed on a flat surface and is based on a mathematical transformation of the earth’s lines of longitude and latitude onto a plane. There are many different projections, each of which distorts distance, area, shape, and direction is some way, therefore no projection can result in a perfectly accurate flat map. Check out the Avenza Projections Guide for a more detailed information.

Georeferencing

Georeferencing involves aligning geographic data to a known coordinate system so it can be viewed, queried, and analyzed relative to other geographic data on the same map. Georeferencing may involve shifting, rotating, scaling, skewing, and in some cases warping, rubber sheeting, or orthorectifying the data to improve accuracy.

Graticules and grids

Graticules are the network of longitude and latitude lines on a map or chart that relates points on a map to their true locations on the earth. You can think of this a grid system – in fact, the terms are sometimes used interchangeably, but there is a subtle difference. Graticules are derived from 3-dimensional ellipsoidal shape of the earth and are formed by the the lines of latitude (parallel lines circling the earth), and lines of longitude (non-parallel lines converging at the earth’s poles). A grid system is comprised of a set of parallel and perpendicular lines that are superimposed on a flat projection of the earth, creating an x,y coordinate system. An example of a grid system is the Universal Transverse Mercator (UTM) system.

Themes

In MAPublisher, MAP Themes are a collection of thematic cartography tools designed to automate how styles and symbols are applied, charts are produced, and data is plotted. There are three themes which you can be customized to suit your needs: Stylesheet, Chart, and Dot Density. MAP Themes offer a lot of flexibility as they can be edited, applied, duplicated, automated, exported, and cleared without affecting the spatial referencing of map features.

This is just a small sampling of the more robust glossary of terms available in the our MAPublisher and Geographic Imager documentation packages.

MAPublisher Features We Love

MAPublisher has been simplifying the process of making maps beautiful for cartographers for more than 20 years. We are always adding new features and improving others, some of which have impacted the overall workflow and affect a majority of users. Other are more ‘niche’ in their application and the functions they perform. Here are a few favourite features that you may, or may not be aware of, as identified by the people who helped design and build them.

MAP Tagger Tool Michael L. – Product Marketing
I like the MAP Tagger Tool because it’s incredibly fast to create labels by clicking features on the artboard. Labels are created using attribute data as a source for the labels. In dense areas, the Map Tagger has flexibility to style and attach leader lines according to placement rules.

MAP Web Author Will H. – Sales
The MAPublisher users I speak with are usually impressed with Web Author and are surprised that it is included in the MAPublisher package. MAP Web Author lets Adobe Illustrator documents with GIS attributes be exported to interactive HTML5 web maps complete with callouts, rollovers, layer control, search, pan and zoom controls. With a little bit of knowledge of CSS (Cascading Style Sheets) and JavaScript you can embed interactive maps into any web page. The map below was created by the National Park Service.

MAPublisher MAP Web Author

Scale and Rotate by Attribute Andrew P. – Software Architect
We added this for a customer who had an interesting use case involving a pattern fill for lava flow. The map broke down an area into sub-areas by lava flow (direction, intensity, etc.). He wanted a way to use the attribute data he had in his map to automatically do a bunch of things he would otherwise have to do by hand, very carefully. In particular, he used the feature’s ability to rotate the pattern of area to match the lava flow direction, which sounded very cool (no pun intended) to us!

MAP Locations Tool Michael L. – Product Marketing
Most users don’t know what MAP Locations does (allows you to define real world coordinates for a location in a document) and how it’s actually useful. It sounds complicated, but it’s actually simple and far reaching throughout the product. MAP Locations can be used in several MAPublisher tools as references for georeferencing, for corners, for locations to draw lines, and locations to plot points. They can also be used to identify map and page anchors.

MAPublisher MAP Locations Tool

Add Calculated Data Andrew P. – Software Architect
Add Calculated Data is essentially a tool to update or add attribute data, but it allows users to feed in things that a user would find difficult to calculate themselves such as centroids, north angles, and art bounds. It also lets you pull in and store data like stroke or fill colours, in case you need to export them to a format that doesn’t support colours natively. You can even have it pull in elevation data!

The Avenza Resources Blog regularly published tips on how to use various MAPublisher tools. Detailed documentation is also available on our website.

Indexing Your Atlas Just Got A Whole Lot Easier

Whether you’re an experienced atlas maker or embarking on your first project, we all know producing an atlas is no small task. In short, an atlas consists of a series of maps and an associated index. Seeing that cartographic content often takes centre-stage, when planning your project it is easy to assume that the map-making process will be the most demanding. However, the proper indexing of map features is often by far the largest individual task when it comes to producing an atlas and can be quite burdensome.

You will be happy to know that MAPublisher 10.1 makes indexing that much easier with the addition of the Include Page Numbers option to the Make Index tool. This advanced option completely automates the indexing of page numbers while also enabling the indexing of two page maps on a single artboard.

For atlas makers, this new addition will streamline and improve the indexing process making it a key enhancement considering the primary function of an atlas index is to help the user locate features and points of interest on map pages.

Let’s take a look at a basic street atlas of Cochrane that was created using MAPublisher 10.1. Cochrane is a town located in Northern Ontario which is not only famous for its mascot Chimo but also for being the hometown of Tim Horton, founder of Canada’s largest coffee chain.

The atlas is divided into four sections: grid cells A1, A2, B1, and B2. Each cell contains two separate map pages numbered two through nine.

The following is a simple example which demonstrates the page indexing for atlas pages eight and nine found in grid cell B2.

Atlas makers can now index their page numbers as easy as one-two-three!

Step 1

To start, using the MAPublisher Grids & Graticules tool, generate an Index Grid with one column and one row (1×1). Although the Index Grid option was selected, the Graticules or Measured Grid options can also be used if it better suits your atlas design needs. Additionally, Cell Reference Labelling was enabled and the advanced labelling options were set as displayed.

Step 2

With your Index Grid created, access the Make Index tool which will initiate the map indexing process. Since we’re indexing streets in this example, we’ll go with the Make index based on feature position and attribute value. The feature position will be relative to which page or pages the street falls on while the attribute value will reflect the street’s name. In this example, streets which span two atlas pages have been highlighted with a yellow background on the map.

Step 3

Since a single artboard is being used to map features which span two atlas pages, the Advanced option Include Page Numbers will be enabled with a horizontal page layout dividing the artboard into page 8 and page 9.

Simply click OK twice and your atlas pages will be indexed with the results written to a delimited text file as displayed below. From here, this file can be formatted and refined within a software like Microsoft Excel, Google Sheets, Quark Xpress, etc.

Portion of the delimited text file output:

Same portion imported into Microsoft Excel:

Note: streets which span two pages have been highlighted to correspond to the map example.

By necessity, indexes are created towards the end of each project when atlas delivery deadlines are looming. It is therefore very important that the technology and methods used be robust and efficient. The introduction of the Include Page Numbers option has enhanced and simplified the map indexing process while meeting the specialized needs of atlas cartographers.
