PDF Maps Support - iOS

PDF Maps is a fast and powerful geospatial PDF reader for your Apple iPhone, iPad and iPod Touch devices. It renders maps quickly and features intuitive multi-touch gestures for easy navigation. With PDF Maps, you can download and open saved maps, pan, zoom, use GPS to locate yourself on the map, drop multiple placemarks, add attribute data, and measure area and distance. There is even support to open up GeoTIFF images. The easiest way to get maps is to download them directly from the Avenza Map Store.

With the release of Adobe Acrobat 9 and Adobe Reader 9 a new geospatial feature set was introduced to the Adobe PDF specification. Geospatial PDF files are PDF documents that contain geospatial information such as real world location and/or GIS attributes. Geospatial PDF documents can be created in some GIS applications such as ArcGIS and Mapinfo and from within Adobe Illustrator and Adobe Photoshop with the aid of the MAPublisher and Geographic Imager plugins, respectively. The geospatial data contained in a geospatial PDF document may be accessed and used (for example to locate a specific point or measure distances) without the aid of any additional plugins, using tools found natively within Adobe Reader 9 and Acrobat 9.

The Avenza Map Store contains spatially referenced maps from around the world including USGS and Canadian Topographic maps. The Avenza Map Store can be accessed directly through the app where in-app purchases can be made. Maps can be downloaded for free as well. See more info about the Avenza Map Store.

Yes! You can create your own geospatial PDF maps and GeoTIFF files and load them into the app using several methods. 1. Use the iTunes File Sharing feature to load maps from your computer; 2. Load maps from the Avenza Online Maps Library; and 3. Load maps from a network/server.

Every map varies in how it is created. For best results, use GeoTIFF or geospatial PDF documents that have been optimized. Also, large maps require more processing and it is recommended to use PDF Maps on iPhone 3GS or better, 3rd generation iPod Touch or better, or iPad because of their faster hardware specs.

The geospatial PDF must be properly and accurately georeferenced and comply with the Adobe Acrobat PDF 1.7 specification (such as maps produced using MAPublisher or ArcGIS). Also, in Adobe Acrobat, use Advanced > PDF Optimizer to create a balance of small file size and good quality. Large rasters in the map could increase file size significantly, so try to use optimized/compressed images and only when necessary.

Yes! Maps are stored on the device and can be used offline. This is a great feature for travelers who wish to load up maps before they travel outside of their home network coverage area - no roaming data charges! It works great with using an iOS device that has GPS built-in.

We've developed a "pdfmaps" URL scheme that lets you open PDF Maps on your website. This pdfmaps scheme also has several parameters where you can customize how a PDF Map opens. See this thread on the Avenza User Forum for more information.

The following is a list of supported gestures and what they perform:

• Single tap and drag: pan the map
• Single tap and flick: pan the map quickly
• Single tap: hide all placemark labels
• Single tap and hold: pick up a placemark, drag to reposition
• Double tap: zoom-in and centers
• Two-finger double tap: zoom-out and centers
• Expand: Zoom-in
• Pinch: Zoom-out

First, tap the Maps button to show the list of maps. Perform a left-to-right swipe on a map in the list, then tap Delete. Alternatively, tap Edit, tap the red and white Delete icon, then tap Delete. The map can also be deleted in the map preferences.
