Strategy for balancing the preservation of area, shape, and topology during polygon-to-raster conversion

We proposed a balanced strategy for decreasing multiple types of rasterization errors to preserve the spatial attributes of the area, shape, and topology during polygon-to-raster conversion. Starting with the outcome of the conventional rasterization algorithm, the proposed strategy first attempts to reassign as few raster cells as possible to compensate for the loss in the shape attributes. The strategy then corrects the topological changes according to the real topologies of vector polygons. Finally, the areas in the raster regions are coordinated with those of the corresponding polygons to preserve the area attributes. <br>
