THE ECORS SYSTEM: A MOBILITY DECISION- MAKING TOOL BASED ON EARTH OBSERVATION DATA

摘要

In the present work, a decision- making system was designed, developed and tested in order to estimate vehicles mobility in both cross- country and roads modes. The ECORS system is based on processing, interpretation and data- fusion processes from remote sen sing data, existing databases, including e - sources. Computing algorithms include slope computation, moisture index, land use and soil classification, road description, etc. Results are compiled in decision- making maps where two levels of information are av ailable: NOGO and velocity maps, depending on data exhaustiveness. Validation processes have been carried out for verifying the coherence of these maps. Results show a good agreement between prediction and field observations, except for terrain with high complexity or non- exhaustive data. As perspectives, new field validation will be carried out in the next few months, particularly for testing the system in zones representative of operational areas.
