How to extract a cell from a polygon?
You could try the Extract by Polygon (Spatial Analyst) tool to get the cells from the raster that would intersect your polygon. Then on the new raster run a Summary Statistics (Analysis) to get the Mean of the cells in the raster.
How to calculate average value of overlapping polygons?
#Then, each feature is converted to raster, and after #a logical conditional expression gives a value to the pixel according the intensity (high=3,medium=2,low=1,nodata=skipped). #Finally, all these rasters are summed and divided by the number of days, in order to #calculate an average value.
How to extract based on a polygon in ArcGIS?
To extract based on a polygon in a feature class instead of providing a series of x,y pairs, you can use the Extract By Mask tool. The center of the cell is used to determine whether a cell is inside or outside a polygon.
What to do with overlapping polygons in GIS?
You should use the Union tool from ArcGIS. It will create new polygons where the polygons overlap.

Which is an example of line on Polygon overlay?
Below is an example of line-on-polygon overlay. The line is split at the polygon boundaries, and each of the resulting line features has the original line attributes plus the attributes of the polygon it fell within. In raster overlay, each cell of each layer references the same geographic location.
How does the overlay function in ArcGIS work?
The overlay function splits features in the input layer where they are overlapped by features in the overlay layer. New areas are created where polygons intersect. If the input layer contains lines, the lines are split where polygons cross them. These new features are stored in the output layer—the original input layer is not modified.
