Hi!

I'm trying to run a temporal analysis in Land Change Modeler from ClarkLabs.

Land Change Modeler uses rst files (Idrisi raster files). After the export as bmp and import in Idrisi, I'm trying to use the product.

In LCM parameters I've inserted the rasters (land use from 2000 and 2005). It's fine and when I press continue I'm getting this message: input image dimension do not match.

I don't know how to continue...
The images are identically by dimensions (same area) and resolution...

Maybe somebody knows a method.

I've attached the error message.

Thank you!

Sincerely,
Adrian

I think that error comes up primarily because the raster files have different Cell sizes, because it cannot combine rasters with different cell size. Other than that, I'm not sure.

Cheers,
David

Dear David,

I have 2 rasters. The first one has 13 classes and the second one only 4 classes. 4 classes from the second raster are the same with the first raster.

Do you propose that should I have same number of classes, eventhough I have empty classes in the 2nd raster?

Sincerely,
Adrian

I've created the rasters once again, this time having the same classes, but for 2005 with empty records. I've started the land change modeler and when I press continue same error...

I don't know where seams to be the problem....

Use the Window tooll to convert all images to same size "From file menu select reformat, then window " Just make sure the image dimensions are the same for all your images from here. You can actually do this on your classified images! It worked for me!
