SLEUTH is a cellular automata specifically designed to model urban growth. It only models the change from non-urban to urban cover. A major challenge for this tool is the data acquisition process. It does not require or accommodate input from stakeholders.
|INPUT - REQUIRED||[Spatial] slope, landuse(at least two), exclude (constraints), urban, transportation, hillshade [Non-spatial] dispersion, breed, spread, slope, and road gravity.|
|INPUT - OPTIONAL||[Spatial] Urban area from more than 4 time periods, and roads from more than 2 time periods for model calibration [Non-spatial] Growth parameters|
|OUTPUT||Time series of urban area images and statistics|
|HOW ARE SCENARIOS DECIDED?||
Scenario is decided by trend-based simulation using given urban growth model.
User can alter parameters to generate alternative scenarios
|FORM||Standalone C program|
|CAN I ALTER THE MODEL?||Yes, the model is open-sourced.|
|SCALE/RESOLUTION||Local to regional|
|REQUIRE GIS TOOL TO RUN THE MODEL?||No. GIS tools are likely needed for preparing and presenting data.|
