I am looking for a specific help.
I have a 5m satellite image that I classified in ENVI. I brought this classified map into ArcGIS 10x as a .dat image and extracted the raster class for every pixel centre (5m) as a point shapefile. Now I want to intersect the point shapefile with a polygon shapefile: e.g. I have a 160 ac quarter section polygon and have 100's of 5 m pixels within it. My goal is to attribute the field polygon with the dominant raster class. I am thinking this is a matter of clipping the points within the field polygon, counting the number of raster classes, and selectiing the raster class with the highest count and attributing it to the field polygon. I am wondering if there is anyway to automate this in ArcGIS?
Can anyone please comment what are their thoughts on how to achieve this?
Please let me know. Thank you.
