Hi, there, I have been working on running the habitat quality model. An error occured which says :“ValueError: Raster at H:/xm/Habitat\intermediate\kernels\kernel_Agriculture_c.tif could not be opened”. It also seemed weired in that the model was running for too long (over 6 hours) for my study area (about 1000*3000 pixels). The log files and corresponding data are attached for your information. Thank you all in advance.
That is very strange because I run the model for Habitat Risk Assessment and it only took like less than 20 minutes. Do you have enough RAM and space in your laptop? If you don’t have enough RAM and space. May be it will require many times to run the model.
InVEST is really sensitive. Please make sure the name of your raster data input is the same with the name written in your threat and your sensitivity table. Pay attention with Lower case/upper case/check whether it is the same name or not.
I think that your raster data input is written with “kernel_Agriculture_c”. However, i did not see “kernel_Agriculture” in your Threats_Data and Sensitivity csv table. You wrote it only “Agriculture” in the threat column.
Please check it again. Make sure everything is the same. Let me know if you still have error message.
The extents appear to be in Lat, Long still as opposed to being projected in meters. This makes me think that the pixel size is actually in decimal degrees. How did you go about projecting this data? Could you try reprojecting it in QGIS or ArcGIS to the desired projection? I believe in QGIS the process is found in raster - > projections -> warp.
Thank you for the help, Doug. It seems that I failed to tranform the raster units into meters previously and the projections were indeed in degrees. I followed your instructions to reproject the rasters and the model ran successfully! Thank you again for the consideration.
Thanks for your help. It turned out that my errors were resulted from the threat rasters were incorrectly projected (in degrees). The “kernel_Agriculture_c” was one of the files produced during the model running process. The model ran successfully after I reprojected all the rasters and it took only a few minutes.
