PCRaster = A dynamic modeling free software for distributed simulation models in ecology, hydrology, and geography.
Entry ID: PC_Raster
Abstract: PCRaster is a dynamic Modeling system for distributed simulation models. The main applications of PCRaster are found in environmental Modeling: geography, hydrology, ecology to name a few. Examples include rainfall-runoff models, vegetation competition models and slope stability models.
PCRaster is a raster Modeling environment. It includes sophisticated raster GIS functionality emphasizing on ... analytical capabilities. PCRaster uses a scripting language for constructing models describing processes through time. These dynamic simulation models can easily be constructed using the rich set of model building blocks and functions found in PCRaster.
Furthermore, The Dynamic Modelling language of PCRaster provides a set of more than 120 spatial and temporal operators that can be used for building (static) Cartographic Models and Dynamic Models. These include:
* Point operators
analytical and arithmetical functions, Boolean operators, conditional statements, operators for relations, comparison, rounding, (random) field generation
* Window operators
for calculations in moving windows of variable size (highpass filtering, edge filtering, moving averages, etc.)
* Area operators
for calculations in specified areas or classes
* Spread operators
for calculation of distances or cost paths over a map
* Geomorphological operators
functions for hillslope and catchment analysis, definition of hydrological topology
* Hydrological operators
for modelling transport (drainage) of material over a local drain direction map with routing functions
* Time operators
for retrieving and storing temporal data in iterative Dynamic Models
