I have some raster data for the US. It is this dataset, classifying land into 8 different classes. 

I need to figure out how to analyze how much of each land class is inside a state. (For example, Minnesota has ### sq km of class 1). What tools or steps might be appropriate for this?

I'm a bit stumped because since it's raster data there is no field in the table for the class and I tried converting the raster to polygon (took three days!) and it didn't create a field for the class. 

What might be appropriate?

Thanks!

Then calculate the area from the raster cell size.

Hi @RebeccaSchewe

You can use Tabulate Area (Spatial Analyst): https://pro.arcgis.com/en/pro-app/latest/tool-reference/spatial-analyst/tabulate-area.htm

If you working in Enterprise you can use this tool: Summarize Raster Within (Raster Analysis) https://pro.arcgis.com/en/pro-app/latest/tool-reference/raster-analysis/summarize-raster-within.htm
