Why is raster viewing important if vector viewing is readily available?
Raster data has many advantages over vector data. Raster data has a much greater level of detail of the physical environment than vector data since all features are shown at once. Vector layers may include roads or transmission lines while raster data will depict the exact dimensions of the roads or the trees surrounding a particular transmission pole. Humans manually create vector data while raster data illustrates the actual physical environment pixel for pixel.
