Geomorphons (geomorphologic phonotypes) are landforms computed from a digital elevation model based on the principle of pattern recognition and the concept of computer line of sight (Jasiewicz and Stepinski 2013). This geomorphon map was calculated using ArcGIS Pro following the same approach as the dataset “Pennsylvania Geomorphon Landform Maps 2021”, but using the topographic dataset “Pennsylvania 3m lidar digital elevation models 2019”.
The final product includes 10 most common landforms: flat (FL - 1), peak (PK- 2), ridge (RI - 3), shoulder (SH - 4), spur (SP - 5), slope (SL -6), hollow (HL - 7), footslope (FS - 8), valley (VL - 9), and pit (PT - 10). This project was funded by the Pennsylvania Department of Environmental Protection (PADEP) through its Water Program. April 2025.
