Open Street Maps has more than 750 hiking routes totaling 13 thousand kilometers of scenic trails across the Western Indian Himalayas. This large hiking network enables us to plan continuous trans Himalayan traverses. Planning a traverse can be done on mobile apps like OSMAnd although smaller mobile screens are not ideal for longer distance planning. A larger desktop / laptop screen is more suitable for planning traverses. One can use more advanced GIS based software tools which are powerful but involve a steeper learning curve and powerful hardware. A tutorial on traverse planning in QGIS can be found here.
Looking for easier web based tools to get started I came across several options here. One nice web site is nakarte.me which offers numerous OSM based and other layers. Similar to OSMAnd and QGIS users can add markers on base map layers marking important POIs along planned traverses like mountain passes, hamlets (food supply), campsites and shelters (night stay), stream crossings and more. The mapy.cz layer gives a crisp topographic (contour) map clearly showing hiking trails for planning traverses:
Users can add custom layers like Waymarked Hiking Trails to get a birds-eye view connecting individual OSM hiking routes into long distance traverses across ranges. URL: https://tile.waymarkedtrails.org/hiking/{z}/{x}/{y}.png
For more detailed planning (terrain details, remote settlements, unmapped trails and paths), one can overlay Survey of India maps using a Custom Layer. URL: https://indianopenmaps.fly.dev/soi/osm/{z}/{x}/{y}.webp
Users can create / import multiple tracks each marking numerous POIs and tracks which can be exported as GPX and imported in OSMAnd on your phone for navigating the planned traverse. Users can view an elevation profile for a planned traverse to giving insight in the overall altitude gain and drop along the planned route.
