Handling GeoJSON Files with Unspecified Projected Coordinate Systems

In the latest GeoJSON specification (2016), the coordinate reference system for all coordinates is a geographic coordinate reference system—using the World Geodetic System 1984 (WGS 84) datum—with longitude and latitude units of decimal degrees. The previous specification (2008) allowed for the use of alternative coordinates systems, but this was removed because of interoperability issues.

Use MAPublisher to Import Layers from ArcGIS Online Directly Into Adobe Illustrator

With the latest release of MAPublisher 9.9, it's now possible to easily import layers directly from an ArcGIS Online account or an ArcGIS web service. This will allow you to use shared data layers within your ArcGIS Online organizational account and connect to publicly available map servers from various online sources.

ArcGIS Online is a collaborative web GIS that allows you to store and share GIS data using Esri's secure cloud. Before, you may have had to download layers as shapefiles to your local machine and then import them into Adobe Illustrator using MAPublisher. Now, MAPublisher has a much improved workflow to get ArcGIS Online layers into Adobe Illustrator will full georeferencing, all map features, and attributes.

Currently, the types of datasets allowed are Feature Layers, Map Image Layers and Tile Layers. To load a layer, use MAPublisher Import as you would with any data type and select ArcGIS Online from the Format drop-down menu. Click the login link to enter your ArcGIS Online credentials to access your organization’s web portal.

Exporting from QGIS to Avenza Maps

In the latest release of QGIS, it's possible to export maps from the Print Composer that is compatible with the Avenza Maps app. The Print Composer tool in QGIS is used for creating map layouts. In previous QGIS versions, it would export maps without spatial reference information meaning maps would need to be georeferenced post export to be compatible with Avenza Maps. As of version 2.16, it's possible to export files with an embedded spatial reference. QGIS can export the following formats that can be read by the Avenza Maps app:

Easy Map Creation with WFS and WMS

Online services can be used to create high-quality maps without the need to download and maintain large spatial datasets or spend time designing base maps. In this post, we'll use two online sources to import data and create a map showing the potential energy generated from existing and proposed wind power projects in the state of Massachusetts.

What Is The .pdfmaps File And How Does It Work?

What is the .pdfmaps file?

In addition to having access to more than 350,000 maps in the PDF Maps Store, you can also import your own geospatial PDF and GeoTIFF files into the PDF Maps app. If you have a large collection of maps and data, you may already know that loading all these files can be cumbersome and time consuming. Luckily, there's a better solution to do this. The .pdfmaps file was devised as a solution for people or organizations who wish to load large collections of maps and data without having to import them one at a time. Here's how it works.
