The project was funded by the Pennsylvania Department of Environmental Protection (PADEP) through its Water Program. Years ago, hunting for free geospatial data was rather challenging. The ORs are 200m, 2*AVW, and 4*AVW for zones of headwater, large-valley, and extra-large-valley, respectively. OR = ORzone, IR = 20 m, FT = 1, and FD = 0) based on zones and the average-valley-width (AVW) at drainage area of 26 km2 of each county. The second set of maps are geomorphons calculated using a dynamic zone-parameterization system (i.e. OR = 200 m, IR = 20 m, FT = 1, and FD = 0) adapted from the Chesapeake Conservancy (Baker et al. The first set of maps are geomorphons calculated using the default parameters (i.e. This dataset consists of two sets of geomorphon maps for all 67 counties of Pennsylvania. The county level 3-m LiDAR (Light Detection and Ranging) DEM produced by the PAMAP Program was used for geomorphon calculations.
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).

DESCRIPTION v.proj allows a user to convert a vector map in a specified mapset of a specified location (different from current) with projection of input location to the vector map in a current mapset of current location with projection of current location (both projections are defined by corresponding PROJINFO files). Project goals for the Committee on Climate Change. Este taller es introductorio a las capacidades de procesamiento de GRASS GIS relevantes para la ecologa de paisaje. The geomorphon algorithm was executed using an open source package, r.geomorphon, under the GRASS GIS environment. GIS Spatial Environmental Data Scientist. Este es un material preparado para un taller de la US-IALE 2017, que lleva el nombre de Unleash the power of GRASS GIS y se realiz el 11 de Abril de 2017 en Baltimore. and compatibility of GRASS with Python, PROJ and GDAL libraries which. Geomorphons (geomorphologic phonotypes) are landforms computed from a DEM based on the principle of pattern recognition and the concept of computer line of sight (Jasiewicz and Stepinski 2013).
