I made my own LULC data using the landsat images and I drew my own polygons and ran maximum classification. I exported it to a tif file. I checked that rasters can be tif files however when I tried to import my LULC data to the InVEST model it did not accept it. Any idea why. I checked that the sample data is also tif files.
Hi @reyesmariana -
Yes, you should be able to use TIFFs for rasters. Can you send us a screenshot of the InVEST model window so we can see the file name you’re entering, and the exact error message? Thanks.
I made my own LULC map and it is raster I export it as TIFF but not sure why it cannot be accepted. thank you
Hi @reyesmariana , could you click on the red X and take a screenshot of that? It should tell you what the error message is there.
If that doesn’t work or isn’t clear, could you share the GeoTiff with us so we can take a closer look?

@reyesmariana thanks for posting the error. So which coordinate system does that raster have? As the User Guide notes “All spatial inputs must be in the same projected coordinate system and in linear meter units.”
XY Coordinate System WGS_1984_UTM_Zone_51N
Linear Unit Meter (1.000000)
Can I ask if it was because my file is not processed as a GDAL? Thank you
Driver: GTiff/GeoTIFF Files: /Users/jdouglass/Downloads/Guandu_20221026.tif Size is 1052, 873 Metadata: TIFFTAG_RESOLUTIONUNIT=2 (pixels/inch) TIFFTAG_XRESOLUTION=96 TIFFTAG_YRESOLUTION=96 Image Structure Metadata: INTERLEAVE=PIXEL Corner Coordinates: Upper Left ( 0.0, 0.0) Lower Left ( 0.0, 873.0) Upper Right ( 1052.0, 0.0) Lower Right ( 1052.0, 873.0) Center ( 526.0, 436.5) Band 1 Block=1052x8 Type=Byte, ColorInterp=Red Band 2 Block=1052x8 Type=Byte, ColorInterp=Green Band 3 Block=1052x8 Type=Byte, ColorInterp=Blue
So in order to have this work in InVEST, this raster must have its spatial reference (origin, projection, etc.) included in the file itself. This can be done with GDAL, but can also be done with ArcGIS (though I’m not sure how to do that).
