We need to create a map for a Lowrance HDS-7 Fishfinder with GPS ([url removed, login to view])
Because there is not a map that I can buy to install on my GPS that I can use to navigate some rivers and lakes in Colombia I need to create it.
It's necessary to create the map in vectors and it should work in my GPS. I did a map with the program Global Mapper and it works in my GPS, but you can use the program you want, I will need the sources to modify it and put it back to my GPS.
My GPS should know that it's a river or lake, in case I want to go to point to a site A to B, it should look for a trace inside the river or lake and not in the land.
For now I need those Colombian rivers:
1. Río Meta
2. Río Malacacias
3. Río Yucao
4. Río Orinoco
5. Río Bita
And those Colombian lakes:
1. Lago de Tota
2. Embalse de Tomine
3. Embalse Neusa
4. Embalse del Sisga
