I never heard of this map type. What`s their advantage over other map types like http://mobac.sourceforge.net/) and where is this map type common/widespread? :) I support this too, geoPDF allows way better options for map appearance, and it also can be edited easily in common graphic vector programs (for ex. Illustrator). I often need maps with custom fills of areas, etc, and thats not possible, nor easily done with current tools. So I end always with rasterized map, which isnt what i want .. I use Locus to collect data in the field. I use ArcGIS to maintain data in the office. I need the two programs to work together. I can export my map, its contents, and the attributes of those contents, from ArcGIS to a georeferenced PDF, but I cannot open this in Locus. Please help. Unfortunately Locus does not support geoPDF files. Anyway it could be possible to convert these format into sqlitedb format using Mapc2Mapc software. I dind’t try it but it could work. On the other hand you lost all advantages of geoPDF during conversion. How to convert: Source.
