Land Developability

 

 

Land developability is a measure of land availability for future conversion and development in a geographic entity, such as a state, a county, a city, a census tract, or other geographically aggregated units. The land developability index is generated using spatial overlay methods based on data layers of surface water, wetland, federal/state-owned land, Indian reservation, built-up land, and steep slope, which are all seen as undevelopable. The land developability index can be used for regression modeling when land use and development is a consideration of an analysis, for detecting potentials for land conversion and development, and for predicting the direction of future land use and development.

 

The land developability index is an ongoing project led by Dr. Guangqing Chi at the Pennsylvania State University. The index could be refined to finer geographic scales, extended into several time points, and modified by including additional data layers. For specific needs, please contact Dr. Guangqing Chi.
