[GRASS-user] r.in.gdal Successful; No Map Display with Python GUI

   I read the wxPython GUI web page, and it tells me that a raster map listed
in the layer manager should be visible in the map display window. But, the
DEM grid file I imported is not visible.

   This suggests to me that I missed a step here. Clue stick or pointer
greatly appreciated.

I am not fully sure if I understand well. Anyway, right click on the
map layer and "Zoom to selected map(s)" ?

Martin,

   The wxPython UI lets me zoom and pan, but there is nothing to be seen. I
just ran r.support, but that made no difference.

   When r.in.gdal runs on an ARC/Info GRID file, is the result a raster
surface or a sites file with (in the current situation) 461,968,584 points?
If the latter, then I suppose that I need to run s.to.rast3 or s.surf.rast.
Do I also need to run g.region again before doing the latter?

Thanks,

Rich

Add imported raster map layer to Layer Manager, then right click to
get popup menu and choose "Zoom to ...".

Martin,

   That's the only map layer I've imported so far. It's loaded in the Layer
Manager, but right-clicking on that window does nothing. No menu appears. I
just re-ran g.region to ensure all values are correct based on the source
metadata. It does.

I meant right click on map layer in Layer Manager, not Map Display...

Martin,

   Well, that does make a difference! Thank you.

   It will take me a bit of time to get used to the new UI, but it's so much
more rational than that which I used with 4.3.

Thanks very much,

Rich
