Ground Models (TIN)
InfoWorks ICM supports the use of a TIN (triangular irregular network) ground model to represent the ground surface in the area covered by the model. The ground surface is represented by triangles with known elevations at the triangle vertices.
InfoWorks ICM supports the following TIN ground model formats:
|
Format |
File Suffix |
Description |
|---|---|---|
|
Arc/Info TIN |
NET |
Use the UNGENERATETIN command with the NET option in Arc/Info to create a .NET file containing lists of nodes, edges and triangles. This .NET file can then be imported into InfoWorks ICM. |
|
Shapefile |
SHP |
A TIN can be exported from ESRI ArcGIS as a Shapefile (SHP). This .SHP file can then be imported into InfoWorks ICM. |
|
InfoWorks ICM Internal |
IIM |
This is the internal format used by InfoWorks ICM. When importing other file types they are converted to this format before use. The format is not published. The TIN cannot be edited directly in this format. However, you can export a ground model to an IIM file for subsequent import to another database or model. |
| 12D | 12DA | 12D surface is commonly used in the Asian - Pacific region and can be imported as a ground model for use in InfoWorks ICM. |
| XPTIN | XPTIN | A TIN can be exported from XPSWMM/STORM in XPTIN format. The XPTIN file can be imported as a ground model for use in InfoWorks ICM. |
| LANDXML | XML | A TIN can be exported from LANDXML in XML format. The XML file can be imported as a ground model for use in InfoWorks ICM. |
