Any software for PC which can be used to view waypoints in offline mode(no internet connection) and maps can be downloaded separately .For eg I have my track saved in *.gpx format .
Try QmapShack: https://bitbucket.org/maproom/qmapshack/wiki/Home
This software can load offline maps in Garmin format … and you can download OSM based maps in that format:
You could use JOSM with a local web server.
Actually the documentation says URL, not HTTP scheme URL, so it might even work with file: URLs.
You could also pre-stuff the tile cache.
How to load garmin maps into the qmashack software ?I cannot see any option ?
Another option is Garmin Basecamp. It can load OSM maps in Garmin format.
I did not try that on my own so far … what about a google search for “qmapshack garmin” ?
I have found a software Qlankarte Gt which can loads *.tdb maps. Its working offline.
