About the data

The source data for the AFFPI developed areas dataset is the National Land Cover Database 2011 (NLCD 2011), which is provided at a 30-meter resolution.  After extracting the data within our study extent, it was reclassified to three categories:  open water, developed (low, medium or high density developed), and less developed/open space (all other values).  Next, the reclassified dataset was resampled to match the project’s 1-kilometer resolution.  Last, a majority filter was run in order to smooth the final dataset.
