I have the following:
- Digital Elevation Model from SRTM
- LANDSAT Imagery from the same area
I wish to display the DEM draped with the raster band combination (3,2,1) using GRASS GIS.
My attempts to use:
r.composite and then use it as an input to the color model for NVIS results in a B/W rendering of the raster surface.
b. Creating a VTK ASCII file using
r.out.vtk is confusing as there is a confusion what is an input image and what is an rgbmap (created using the RED, GREEN and BLUE) bands of LANDSAT. There is of course no issue with the elevation data. However using
paraview to display the output file
data.vtk fails (does not work).
