I am trying to produce a slope surface raster from a tiff.
The raster has 1 band, pixeltype is 8 bit unsigned integer but I cannot get
the function to work.
Have tried variances of:
ST_Slope(rast, 1, '8BUI') or (rast, 1, 8)
But PostGIS returns ERROR: function st_slope(raster, integer, integer) does
LINE 2: ST_Slope(rast,1,8).
Any pointers as to where I'm going wrong much appreciated
