Spatial Density Analysis in QGIS
Density analysis captures known quantities of phenomena and distributes them throughout the landscape based on the spatial relationship between the measured quantity at each location and the location of the measured quantity. Density analysis captures known quantities of phenomena and distributes them throughout the landscape based on the spatial relationship between the measured quantity at each location and the location of the measured quantity. The Density tool spreads a measured amount of input point layers over the landscape to create a continuous surface. As an example of a density analysis application, consider a retail chain with multiple stores in a particular area. For each store, management has sales from customers. Management believes that customers choose one store over another based on distance traveled. In this example, it is natural to assume that each customer always chooses the nearest store. The farthe...
