DelineateIT error: "The datasets' intersection is empty (i.e., not all the datasets touch each other)"

Hello,

I received my first error trying to use the DelineateIT tool with a DEM (1m res. - 29439x31843 cells).

I already checked the coordinate system of both files (DEM and outlet point) and they are both correct.

Below you can find the error log I received.

Thank you for your help.
Vinc.

Hi @Vincenzo -

Are the DEM raster and outlet shapefile in the same projected coordinate system? If not, that could be a cause of the error. Also, it looks like you’re entering an .ovr file for the DEM, try using the .tif since I’m not sure how InVEST handles .ovr.

The .tif format works better.

Thank you

You might also like the new InVEST version 3.8.0, which has some nice performance updates for DelineateIT. And which won’t even let us make the mistake of using the .ovr !

Thank you Dave,

The 3.7 it allowed me to upload the pyramid file (.ovr)… The 3.8 does not.
