Write: GeoTIFF with single band REAL32 ?

Hi list.

This may be obvious to some, but I'm not very proficient in raster handling.

I'm building a custom process that manipulates one DEM, and checks with another DEM.

Both input DEMs are GeoTIFF with a single REAL32 band that contains the height information. My output should be of a similar construction.

I'm using RasterCellCoercer at the input to vectorize, and ImageRasterizer to create the output image to be stored as GeoTIFF.

However, ImageRasterizer does not offer REAL32 as an option, only multiband RGB(A) and single band 8/16 bit options.

Is it possible to create a single band REAL32 GeoTIFF using FME, and if so, how ?

Using 2020.0

Cheers

Lars I.

Try using the NumericRasterizer rather than the ImageRasterizer.

Thanks, I didn't even know it existed. The naming, the naming. I'll test it asap, and get back.

It worked like a charm :-) Thank you. I still have familiarizing myself with every single transformer's existence on my to-do list.
