Hi @may,

Thanks for reaching out! What kind of geometry does your TIFF contain that you want to convert to shape? There's a few tutorials we have that are good for getting started going from raster to vector:

• Convert from Raster to Vector (this one uses the RasterToPolygonCoercer
• Convert Raster Images to CAD Using Potrace (uses the PotraceCaller, and this one writes to CAD, but you can easily swap out the writer for Shapefile instead)
• And if you have a DEM raster, then DEM Raster to Vector with RasterExtentsCoercer

There's a few methods to choose from here, and I would go with the RasterToPolygonCoercer to start though. If you're new to FME and interested, we also have some free training courses available on Desktop Basics that might be helpful to get used to how FME works and where everything is. Hope that helps!
