tried using OpenTopoMap, garmin.openstreetmap.nl and OSM-Freizeitkarte, the POI Search even for small Countries is very slow when not sorted alphabetically.
Is this a usual behaviour?
How is the POI in the Garmin IMG File internally handled? is it a database? can there be indices on that “tables”? Whats the best way to speedup that?
And last but not least:
Is there a gmap editor (for the compiled img file) which i can use to edit the file, adding POI’s and changing TYP stuff?
I’am on a 2 years journey and i don’t want to carry a full system with me. Network speed is also limited.
I don’t know any program which can add features to an *.img file. The normal way would be to add the data to the input of the program which compiles the img file, e.g. mkgmap or cgpsmapper.
Alternative: Garmin programs like Basecamp or MapSource allow to add Waypoints and you can also import POI using a csv format.
