Avenza Systems has made mobile GIS technology available on Apple iOS devices for everybody to use.
The PDF Maps app is a geospatial PDF, GeoPDF® and GeoTIFF reader for your Apple iPhone, iPad and iPod Touch devices. Easily download, browse and interact with maps. It compliments MAPublisher and Geographic Imager, both of which have the ability to export to geospatial PDF and GeoTIFF. The formats are also supported by common GIS applications including ArcGIS.
PDF Maps is used by companies, organizations and individuals for navigation, information collection, and sharing geographic information and knowledge.
This app gets the job done: PDF Maps introduces a strongly played set of basic features. Besides myself, I setup two non-cartographers with an iPad (3G with GPS) and they were amazed at how easy it was to locate themselves on the map and make notes by dropping markers and they bring it back to the office for me to review.
You guys not only have a great product, but give publishers a vehicle to deliver their product. On behalf of all cartographers and map publishers, thanks very much for your creativity, inspiration, and hard work!
