Quote:My experience with raster charts is sometimes the smaller scale chart has a detail the larger scale has and as such I don't want the app to automatically decide for me to show the larger scale. Also most raster charts have important information in their borders, the apps that attempt to stich them together seem to crop this info out.
The best implementation of raster chart stitching/selection without affecting usability of important information on them is in ForeFlight, a navigation app for pilots. Maps are stitched using best guess and if you want to see side information that is not displayed, a single tap will bring forward the map underneath. It's just like you would do with multiple real paper map on a table. Of all navigations apps I've played with, iNavX is the worst with regards to dealing with raster maps.
