TatukGIS Raster Algebra Engine

The TatukGIS raster algebra engine is a powerful tool for performing virtually any algebraic operations on raster layers with per pixel access. This can vary from a simple sum or subtraction, in which multiple source layers are combined to create a new layer, to complex expressions using statistics, multiple channels, logical operators, and functions.

TatukGIS goes even a step further by integrating vector layers into the raster algebra engine. This enables easily performing tasks such as rasterization of vector layers, selective analysis (e.g., only over the area of a specific object), adding buildings to terrain models, etc.

In keeping with TatukGIS tradition for simplicity of use, the TGIS_RasterAlgebra class exposes only two methods: one adds layers to the engine and the other evaluates the algebraic formula. If images or raster layers are of different resolutions or coordinate systems, the source data is automatically normalized to specifications set by the user. The raster algebra syntax and features are fully described (with samples) in the product documentation.

Raster algebra functionality, found in the TatukGIS Developer Kernel and desktop GIS Editor (as a plug-in) products, is useful for a wide range of industries using periodically collected aerial imagery (or other raster data) such as agriculture, forestry, land management, disaster response, environmental, oceanology, meteorology, military, conservation, etc.
