Ecological Niche Modeling Purpose: – Generate species geographic distribution models – Based on ecological niche concepts

A Complete RM-ODP Case-study to Integrate Geospatial Services and Ecological Niche Modeling Systems

– Defined by species survival conditions

– Describe probabilistic distributions of species – Can be projected onto a map of the study region
