raster intersection

Discussion created by revelsizer on Apr 15, 2013
Hi all,

I am working with rasters of different resolutions (30m and 250m).  The 30m raster is vegetation data.  I want extract data from the 250m data using the 30m data of a certain value (25).  We want to select all 250m pixels that are covered by 80% or more of 30m data with a value of 25.  I've tried the resampling tool but when going from 30m to 250m, many pixels are selected that shouldn't be.  Ultimately, we want to create a point file that aligns with the 250m data; where each point represents a 250m pixel that is at least 80% covered by a certain vegetation type.  Hopefully that makes sense...

Thanks for any ideas
