Dear all,
I am creating a gridcoverage2D (and consequently a geotiff, based on
processing of a source geotiff DEM), and I want to quickly visualize the
results of the analysis. Instead of opening it in some GIS, I would like
to assign a color model to the result.and display it through the show()
method. I tried to change the viewtype, but it does not seem to help.
My GridCoverage2D is created as follows:
WritableRaster hor = ...;
GridCoverage2D gchor = gcFactoryhor.create("hor", hor, env);
gchor.view(ViewType.GEOPHYSICS);
gchor.show();
and I use a GeoTiffWriter to output the geoTiff. Note that ArcMap open
the geotiff fine (requiring classification to assign colors), as well as
a normal image viewer (e.g., XnView), but the result is just a binary
nodata/anydata black and white rendering.
I see that it is possible to assign colors in the GridCoverage2D gchor =
gcFactoryhor.create(...) part, but I am not sure how to map the values
in the raster to the colors. Any hints welcome.
Thanks
Martin
