Windows that are linked together are also resized together and geolinked in various ways. Geolinked windows can also be layered, each showing different bands of the same image. The overlay area appears in the top window and the rest of the image is shown with the band combination of the bottom window. Geolinking can also be performed with multiple base maps. ER Mapper's speed is impressive, especially considering the volume of data being processed.
Tiling occurs very quickly.
The contrast between similar bands in adjacent images can be minimized using histogram matching, which gives the appearance that image borders blend together. This effect can be further enhanced by using ER Mapper's feathering command. Raster overlay capabilities. Selected parts of a raster image can be masked in either opaque or translucent color depending on the values in the cells. Values can be specified using equations involving one or more bands of an image or by selecting regions of the scattergram.
