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:
Avenza Maps Pro users can export layers to shapefile with associated photos. ArcGIS can display these photos using either hyperlinks or HTML popups. This post explains how to export your photos from Avenza Maps and display them in ArcGIS.
First, download and unzip these utilities. The general process for exporting and displaying photos is as follows:
- Export a shapefile with photos from Avenza Maps
- Unzip the exported files to your computer
- Open ArcGIS
- Add the shapefile to the map
- Save the map in the same folder as the shapefile
- Run the “Photo Shapefile Converter” tool
- Set the layer to display a hyperlinked photo and/or
- Set the layer to show an HTML popup
Avenza PDF Maps has the ability to export user created features to KML or KMZ files for use in other applications. Avenza Forum user brymcbride helpfully created a script for Macs using GDAL/OGR to convert KML/KMZ into shapefiles for easy import into other GIS packages. Most GIS packages these days can consume KML/KMZ files, but the real strength of this method is its use of a SQLite database as an intermediate format in the translation process. This has allowed brymcbride to use some SQL formatting to adjust the resulting shapefiles attributes and create a user friendly link to any images that may be associated with a placemark, line or track captured in PDF Maps.
