synesthetic heightmap from image

For Wilbur i like to use the 32 bit BT format

resave the base map as a 32bit floating point
gmic and Nip2 can do this just fine

use GDAL to convert to bt

gdal_translate -of bt  basemap.tiff WilburInput.bt

run a few Cycles of precipitation based erosion and incise flow

and export to bt
( 32 bit has + and - pixel values )

and use gdal to convert to a 32 bit tiff



and a 8 bit normalized copy of the float





for lower coastal area drop the GAMA to say 0.6
then run through wilbur

shaded using the gimp "bumpmap" shader and a 8 bit copy of the heightmap
