I tried with PDF files first but - had problems and switched to JPG's in my search for a solution (back to basics :) ) but nothing helped - I even tried removing the special danish caracters "ÆØÅ" from the file name but that didn't help either. Didn't had the thourght that I shoul also remove the "spaces" - -
After renaming everything works well and I where even able to open the rather big PDF's directly in the app - great thanks !
PS: For future work it would be a fantastic tool if it was possible to mix two or maps in one view - like in the preview function - but having two different maps opened at the same time for easy comparison and switch between the two.
Eg. via a transparacy slider or a sliding curtain actross the screen.
As a hobby I work with LIDAR photos, air/sat photos and old maps as an amaterur archeolog to find not natual patterns that often reveal work or constructions done by human hand - and comparison between the different maps often give a clue to which places to look - and GPS alligned hand held maps is a very good tool to find my way and recognize the terrain.
