Crop Pollination: Model gives larger than expected edge effects when run at different extents
we are currently running the InVEST crop pollination model at two different extents for some tests (150 x 150 km and 50 x 50 km). When we compare pixels at the edge of the small extent to the corresponding pixels at the large extent we get different values (sup_) up to 10 km from the edge (our max foraging distance is only 2.2 km). Does anyone know why the edge effects are so much larger than the max foraging distance? Based on the equation in the documentation it appears that it might be related to the Euclidean distance between cells (Dmx) that is considered ... do you know how this distance is determined?
