Create Elevation Graph
Description
This functor creates the elevation patch graph from neighborhood information and their properties.
Inputs
| Name | Type | Description |
|---|---|---|
| Neighborhood Table | Neighborhood Table Type | Neighborhood relationship between patches. |
| Properties | Table Type | Elevation patch properties table. The table has the format “Patch_Id*:real, Patch_Elevation:real, Patch_Area:real, Patch_Slope:real, Patch_Y:real, Patch_X:real”. The “Patch_Y” and “Patch_X” values typically represent the coordinates of the patch centroids. |
Optional Inputs
None.
Output
| Name | Type | Description |
|---|---|---|
| Elevation Graph | Elevation Graph Type | Elevation patch graph created from neighborhood relationships and their properties. |

Notes
The elevation patch graph is a directed graph whose nodes correspond to the patches defined in the neighborhood table, typically constructed from a terrain map. The edges between nodes represent the adjacency relationships and elevation differences between each patch and its neighbors. The parent nodes of a given node correspond to neighbors with higher elevation, while child nodes correspond to neighbors with lower elevation.
Neighboring patches according to the neighborhood relationship must have different elevation values according to the table provided in “Properties”. Otherwise, an error will be reported.
