RasterLayer
This is a high level function that interpolates an sf object with point geometries in a single pass.
Points must be located within a single contiguous area. The presence of "landlocked" points will cause errors. It may be necessary to increase the value assigned to land areas when using a large range value in combination with a large sized cost rasters (grain x extent). In these cases, the value of land areas should be increased to ensure that it is always greater than the maximum accumulated cost path distance of any given geo-referenced point.
