| - | | Neighborhood Table | [[Neighborhood Table Type]] | Neighborhood relationship between patches. | | + | | Neighborhood Table | [[Neighborhood Table Type]] | Defines spatial connectivity between elevation patches. Elevation patches are represented by their corresponding ids. | |
| - | | 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. | | + | | Properties | [[Table Type]] | Table of elevation patch properties, in the format "Patch_Id*:real, Patch_Elevation:real, Patch_Area:real, Patch_Slope:real, Patch_Y:real, Patch_X:real". Patch_Y and Patch_X typically hold the coordinates of each patch's centroid. Neighboring patches, per Neighborhood Table, must have different elevation values in Properties, or this functor reports an error. | |

| - | 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. | + | The elevation patch graph is a directed graph whose nodes correspond to the patches defined in Neighborhood Table, typically built from a terrain map. Its edges represent the adjacency and elevation-difference relationships between each patch and its neighbors: a node's parent nodes are its higher-elevation neighbors, and its child nodes are its lower-elevation neighbors. Neighboring patches must have different elevation values according to Properties, or this functor reports an error. |
