Content-Type: text/plain; charset="iso-8859-1"Dear all,
I am running native wingrass on a XP OS and I wold like
to show a rast map on "Map Display" windows, and after
check out the values of pixels in a interactive way
by clicking on the screen.
Is there a way of do this?Cheers,

Miltinho,
1) Take a look at the GUI help pages
These are the general steps
Display a map
1) Add a raster layer to the GIS Manager (layer manager)
2) Press the display button on the Map Display window
Query a map
1) Select a raster map layer in the GIS Manager
2) Click the query button in the map display
3) Click on a pixel
4) View the results in the output window
