TINs may be converted to other types of data used in GMS, such as a 2D mesh or 2D scatter points. TINs can be converted by right-clicking on the TIN in the Project Explorer, Right-clicking on the TIN in the graphics window, or using the following commands in the TIN menu:
TIN -> 2D Scatter Points
- The TIN -> 2D Scatter Points command creates a 2D scatter point set from the active TIN . One scatter point is created for each vertex in the TIN. A copy is made of each of the data sets associated with the TIN and the duplicate data sets are stored with the new scatter point set.
TIN -> 2D Mesh
- The TIN -> 2D Mesh command creates a 2D finite element mesh from the GMS - Make TIN Active|active]] TIN . One triangular element is created for each triangle in the TIN. Any data sets associated with the TIN are copied to the new mesh.
TIN Boundary -> Polygon
- The TIN Boundary -> Polygon command creates a new polygon in the active coverage in the Map module corresponding to the outer boundary of the active TIN .
Thiessen -> Map
- The Thiessen -> Map command calculates the thiessen polygons from the TIN and converts them to Map Polygons.
Vertex Strings -> Arcs
- The Vertex Strings -> Arcs command creates an arc in the active coverage of the Map module for each of the selected vertex strings .
