Shapes on a plane: Evaluating the impact of projection distortion on spatial binning
Sarah E. Battersby, Daniel Strebe, Michael P. Finn
2017, Cartography and Geographic Information Science (44) 410-421
One method for working with large, dense sets of spatial point data is to aggregate the measure of the data into polygonal containers, such as political boundaries, or into regular spatial bins such as triangles, squares, or hexagons. When mapping these aggregations, the map projection must inevitably distort relationships. This...
