About Manipulating Layers

TerraBuilder enables you to manipulate the sources you have imported to your project, clipping, resizing, moving and recoloring layers, as required, to create a photo-realistic, geographically accurate database. Some layer information is modified in the Properties Sheet, whereas other information is changed in the layer windows. The following techniques are used to manipulate layers:

§  Polygon operations (clip, null, fill). See the “Using Polygons and Rectangles” chapter.

§  Modification of color parameters. See “Color Adjustment” in this chapter for more information.

§  Adjustment of scale elevation parameters. See "Scale Elevation" in this chapter for more information.

§  Designation of a source’s coordinate system. See “Setting a Source’s Coordinate System” in the “Layer Management” chapter for more information. 

§  Modification of layer dimensions, resolution, and geographical coordinates. See “Modifying Layer Dimensions” in this chapter for information.

§  Adjustment of layer geographical coordinates and UPP using tie points in the layer windows.
