Hi,
I am creating contour lines and contour polygons from a raster geotiff file with 50m intervals. In lowland areas near the sea a lot of tiny lines/polygons are created wherever the elevation fluctuates around value 0-m. GDAL has a parameter (Offset from zero relative to which to interpret intervals) which allows setting an offset so as to reflect only significant low elevations (by setting it to -5 for instance). However this parameter is not present in the ContourGenerator transformer of FME.
Can you think of a workaround for simulating such behavior? Otherwise is it easy to call the GDAL function from within FME?
Thank you!
Best regards,
Olivier
