Previously I've asked an question and Micha gave me a helpful advice:How to find the watershed area for each point in the river network using DEM？
After getting the useful DEM file, I began to setup GRASS and use it to solve my problem, I downloaded it from its official site:Index of /grass64/binary/mswindows/native, choosing this one:
I have downloaded the main program and two datasets, and then launch GRASS after fininshing installation:
I create an new folder and put downloaded datasets in it, in my case,
But as I choose this folder as my GIS data directory, the window soon vanished and nothing came up.
I tried many times but the result was just all the same, so I want to setup GRASS correctly, and then use these two useful modules:
- r.watershed elev=DEM thresh= drain=flow_dir_grid
- r.water.outlet drain=flow_dir_grid basin=basin1 easting=X1 northing=Y1
to solve my problem.
How to setup GRASS and could someone provide step by step guidance?Thanks.
