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.
