When clipping a raster and converting to a polygon, how do I recalculate the count column?

Recommended Posts

Hi from USA !

I wanted to recalcuate the "Count" column when you clip a raster and then convert it to polygon, the count column itself carrys it over from the origional raster. How do I recalculate it in the count column in the polygon ? I know you can do that from the toolbox but what about within the table ?

Thanks for feedback...

the simplest way i think :

divide area of polygon by (pixelsize * pixelsize)

This is valid only if the user has not already clicked on SIMPLIFY POLYGONS

i think if you cut the raster i think that the soft automatic recalcule the count for this new area...chek this is not necessary to recalculate.

The original poster didn't come back to the topic but I think he clipped some raster and converted the clipped raster to a polygon shapefile. He wants count column from clipped raster to be displayed in polygon shapefile may be. He can also use JOIN if that was his purpose.
