Item Details
SUMMARY

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

COST Free
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.
