You could join this attribute to the other shapefiles, then calculate the percentage with the field calculator in the attribute table. you can use this to calculate the area and percentages of each shapefile, then substract the areas from the layers needed (for example a1 a2). share improve this answer follow answered feb 27, 2018 at 9:26 iridium. Convert your raster into polygons using raster to polygon, don't simplify the polygons for more accurate results. percentage of cover for the overlaying polygons is area in zone total original area, to preserve this add a field for original area (let's call this oarea) as the shape areas will be updated during the overlay. Use this method to determine the area of multiple polygon overlaps and multiple instances of overlaps. in arcgis pro, on the analysis tab, click tools to open the geoprocessing pane. search for and open the count overlapping features tool. in the count overlapping features pane, for input features, select all the overlapping polygon layers. Right click 'interarea' and select calculate geometry. select area as the property. use the coordinate system of the data frame. select the desired units, and click ok. add another new double field, percentage, and run the field calculator, where 'origarea' is the original area field from the 'county' layer: [interarea] [origarea] * 100. Use calculate field to calculate percent overlap = shape area shape area 1. if you want more information, such as the ids of the overlapped polygons, run intersect, but enter mypolys twice. this will overlay mypolys on top of itself. the output table table will list each unique combination of overlaps.

With that done add a field in your attribute table naming it percentage (don't name it percent), give it a type of double. when the field is added right click the field and use the field calculator. insert: (shape area of shapefileb shape area of shapefilea) * 100. to get the idea see the code below: ( [shapeareab] [shape areaa]) *100. You can use overlay analysis to combine the characteristics of several datasets into one. you can then find specific locations or areas that have a certain set of attribute values—that is, match the criteria you specify. this approach is often used to find locations that are suitable for a particular use or are susceptible to some risk. Right click the field heading for which you want to make a calculation and click calculate geometry . optionally, you can press ctrl shift g to open the calculate geometry dialog box. click the geometric property you want to calculate. different properties are available depending on the type of layer you're using.
