Hi @ferminjavila,

You can use the transformer RastertoPolygonCoercer to extract vector from raster file.

Has a interesting article Blog's Safe taht describe best way to convert Raster to Vector 3 Ways to Convert a Raster.

Hi @ferminjavila, thanks for posting your question!

If you have something like 'before' and 'after' imagery, you could try Change Detection with the RasterExpressionEvaluator in FME. Hopefully that article gives you a starting point!

Thanks,
