Many different ways to classify land cover types have been developed at the national, state, and regional levels. Systems in use are based on various characteristics that range from objective to subjective. Some of the more popular systems are based on land use or type, morphology, capability, life forms, combinations (e.g., ecoregions, soil, vegetation, hydrogeomorphic features), values, and objectives. Given the large number of classification systems that have been developed, it is often difficult to decide which is most appropriate for a particular situation
At the same time, it is critical to use a classification system that is appropriate for one's application needs and geographic and ecological setting. This decision support tool can help screen the nine major classification systems discussed in EMRIS and assist in selecting the appropriate system.
The selection process is in two formats. One is a prepared paper "Selecting a Classification System." The second format is a computer-based decision support system that facilitates the selection of a classification system by presenting the user with a series of questions. Textual information on the use of the system is included here . Please go to the Information Manager to access the system itself.
