| Summary: | The erosion map data is one of important data used in planning
conservation of degraded land. Generally, erosion data is predicted using a model
because to gain actual erosion requires much resource (timely, costly and labour
intensive). USLE (Universal Soil Loss Equation) is one of existing erosion models
applied worlwide, including Indonesia. Nevertheless, erosion analysis conducted is
based on analysis using vector-based maps. This method involves simplification,
either algorithms or procedures, and subject to subjectivity, so the result has high
uncertainty. This article deals with the idea to build a fully raster-based erosion
modeling. Steps required to obtain raster-based data was highlighted as from the
beginning up to the model validation to get an absolute model. The integration of
remote sensing and GIS was inevitably usedfor the analysis. |
