I have the aspect (raster file) for the roof of buildings at the city scale. Now I want to calculate the area of each aspect group per building. I tied zonal statistics, zonal geometry and etc . Also reclassified the aspect layer and tried to add the Building ID. But I didn't get the desired result. Is there a way to do that? Kindly see the attached
to do it on a per building basis you need the individual 'zones' which can be accomplished using.
Region Group—Help | ArcGIS Desktop
the resultant would be your zone file, then a zonal count would give you the number of cells (times cell area) per aspect by building

Thanks Dan! I performed the region group, then displayed with the link value (shows exact values as for aspect.tif). Also did zonal statistic with the feature zone as the regiongroup.shp + the zone filed as count+ value raster (uploaded aspect.tif). But still didn't get the desired result . I think I am missing something , can you please illustrate the second step in more detail.
need to see what your desired result is in light of what you have.. it may need an interpretation suggestion or modification
After visualizing the product of Region Group , it seems that it is not giving the zone needed (top classification by value bottom classification by Link).
