Elevation Graph Type

Represents a graph where nodes correspond to patches of the elevation map (DEM, elevation map) and the connections in this graph represent the relationship between each patch and its neighboring patches. The parent nodes of a node are those neighbors that have higher elevation than it, while child nodes have lower elevation.

Each node of the graph maintains the following additional information:

• Patch identifier corresponding to the node.
• Elevation of the patch corresponding to the node.
• Area of the patch corresponding to the node itself.
• Combined area of the patch corresponding to the node. The combined area corresponds to the sum of the patch's own area and the combined area of all its parent nodes.
• Slope of the patch corresponding to the node.
• Y coordinate of the patch corresponding to the node. Typically, this is the centroid coordinate.
• X coordinate of the patch corresponding to the node. Typically, this is the centroid coordinate.

Thus, this graph represents a discretized version of the elevation map, where each patch represents a portion of the map with the same elevation.
