Merging classes after supervised classification

KateEkhator74 — Wed, 08 Jun 2022 22:11:17 GMT

I recently downloaded NLCD Landcover imagery raster from MRLC to detect landcover changes between 2019 and 2001, after clipping the raster to my study area, I wanted to condense the classes for example deciduous and evergreen as forest, all type of wetlands as wetland and so on. From the imagery tab I clicked the merge classes tab and the attached screenshot appears. My question is how do I get the classification schema to condense the classes bearing mind that this raster layer has already been classified? Or are there any other way I could condense the classes in ArcGIS pro?

Thanks.

@KateEkhator74, have you taken a look at the Reclassify tool?

Reclassify tool disturb the cells in other classes as well. You can notice variable count for other classes in reclassified raster which we don't want to change. I found this problematic
