Land Area Changes Error With MOLUSCE

[Rid1007]

          Greetings!

When using MOLUSCE to generate Area Changes tables and map, I get an error message as stated. I have reclassified the features to one digit numbers and transform the raster from float to integer. Please help.

Greetings!
I've been trying to update tables for land cover change using MOLUSCE. i'm facing a similar issue when i click on update table. I have reclassified, and geometry is not the problem, all rasters are in Integer format, yet it's not working. I have updated Qgis and MOLUSCE plugin, yet no changes. I'll like to know if you have a solution to this. Thank you.

Hello!

This error says that the number of land use categories in one of the input rasters differs from the number of categories in the other raster.

Unfortunately, MOLUSCE does not yet support the ability to process input rasters that do not match the number of land use categories or the list of codes (unique pixel values) that encode a particular class.

As an alternative to make it possible to work with MOLUSCE, I can recommend you to artificially add one pixel of the missing land use categories to the original rasters. This can be done, for example, using the Serval plugin

Hello everyone! I solved the error by following this recommendation to use the Serval plugin to add the missing class.

Thank you very much!
