In the raster dataset, a zone is a class of elements represented by one or more cells that are connected or disconnected and that have the same value. The
LandUse layer has zones or types of parcels, such as
Forest, and so on.
In this recipe, you will generalize the
LandUse_2015 raster. The generalization process will change the values of the small-region areas to the values of the larger neighbor regions. The parcels with area below
625 meters square are not represented in a classic topographic map at scale
1:5,000. On the sheet map, this polygon area means a square of
5 millimeters. The
LandUse_2015 raster has a cell size of
0.5 meters. For this reason, you will dissolve the regions smaller than 50 x 50 = 2500 cells.
The roads, rivers, and build-up areas...
