I used the dasymetric toolbox to proportion the population of a city based on areas of habitable land. I have the output in a raster file with a corresponding attribute table. My output has a column that has the new population proportioned to each raster zone (there were 42 in total). I have also created a fishnet shapefile.
I'm trying to overlay the raster with the fishnet so I can find out how many people live within each fishnet cell. Though, I am wondering if this is possible in any way.
The software I'm using is ArcGIS 10.4
I am attaching two screenshots. The first is of my raster file with its attribute table and the second is of my shapefile with its attribute table.
My methodology is as follows: I used the nlcd landcover classification raster and clipped it to my area of interest.I then reclassified the raster where I used 0 for areas I consider uninhabitable by humans, i.e. water, ice, etc. then I used 5, 15, 30 and 65 based on population density. Next, I used the dasymetric toolbox to calculate a new population field (NEW_POP in screenshot 1). I joined the raster file with the dasymetric tool output then I deleted areas of the raster with values = 0. The remaining cells can be seen in Screenshot 1.
After that, I converted my landcover raster to a polygon and did a union of the landcover polygon file and fishnet. Then I deleted fields with values = 0.
The output is seen in Screenshot 2.
Is there a way to find the population (derived from the raster file in the column NEW_POP) within each polygon?
