Urban growth modeling
Land use/cover modeling
Test mode will perform a single run through the historical data using the CALIBRATION_*_START values to initialize growth. It will complete the the set number of MONTE_CARLO_ITERATIONS, and then conclude execution.
All output files that can be created in calibrate mode can also be produced in test mode. It depends only upon the scenario file flag settings.
calibrate mode, in test mode annual GIF images of simulated
land cover change are generated and written to the location indicated
by the OUTPUT_DIR
flag. These images may be used to visually assess how the coefficient
values are affecting growth, as well as generate an animation of modeled
historic urban growth.
Calibrate will perform monte carlo runs through
the historical data using every combination of the coefficient values
indicated. The CALIBRATION_*_START
coefficient values will initialize the first run. A coefficient will
then be increased by its _STEP
value, and another run performed. A coefficient will no longer be incremanted
by it's _STEP
value when it's
_STOP value has been exceded. This will
be repeated for all possible permutations of given ranges and increments.
