Using flow accumulation and flow direction grids and a 2km buffer around an input point, create a downstream flow path within the buffered area. Find the distance to the intersected wetlands and nearest impaired water. Find the land use along the downstream path. Uses NLCD 2021 data and NWI scored wetlands processed in 2024 Only for use in WetCAT app. This script is written for ArcPro 2.9
For use in the Wetlands Condition Assessment Tool (WetCAT) viewer. This script only works in Virginia and the APNEP Management boundary in North Carolina.
| Parameter | Explanation |
|---|---|
| Input_Feature_Point | Input location specified by user by clicking on map in the WetCAT map viewer. |
| FillInt | This raster is defined within the script and is used for determining the down stream path. |
| FlowDir | This flow direction raster is defined within the script and is used for determining the down stream path. |
| FlowAccumInt | This flow accumulation raster is defined within the script and is used for determining the down stream path. |
| NLCDReclass5 | A reclassed NLCD 2021 raster used for determining general land cover within the buffered down stream path. It is defined within the script. |
