Hi Hamish,
GRASS Setup Windows, the latest is downloaded.
But I still find that V.Net.Path requires the coordinates of
two end points to be in a ‘File’ for input to
get the shortest path between these points.

In your last mail I had a notion that you indicated that the points can be
‘Mouse Input’, for V.Net.Path.

yes

d.path's default is to take input from the mouse, but there is a new option to use the coordinates from coor= instead, when interactive mouse is not there (native Windows).

d.path and v.net.path are different code which do similar things.

Ravi,

In your last mail I had a notion that you indicated that the points can be
‘Mouse Input’, for V.Net.Path.

Hamish said to use d.path command with the coor option in it. That option is also present in the command GUI as “Starting and ending coordinates:”

Hi
d.path [-gb] map=name [type=string[,string,…]] [coor=x1,y1,x2,y2]
[alayer=value] [nlayer=value] [afcol=string] [abcol=string]
[ncol=string] [color=string] [hcolor=string] [bgcolor=string]
[–verbose] [–quiet]

  1. The above is the command using GRASS6.3 windows setup.
    Through the Display Manager, it stright give as error, if one
    uses ‘shortest path for display’.

  2. So the above command should work, But How can one give mouse input of Coordinates ?

It gave error
G_malloc: out of memory
