GuidosToolbox (Graphical User Interface for the Description of image Objects and their Shapes) contains a wide variety of generic raster image processing routines, including related free software such as GDAL (to process geospatial data and to export them as raster image overlays in Google Earth), and FWTools (pre/post-process and visualize any raster or vector data).

All tools are based on geometric principles and can thus be applied at any scale and to any kind of raster data.

GuidosToolbox also includes MSPA (Morphological Spatial Pattern Analysis), a customized sequence of mathematical morphological operators targeted at the description of the geometry and connectivity of the image components. MSPA features and application examples are described on the MSPA-website.

cost.gif  Cost analysis: cost map, least cost path, bypassing an obstacle, and user-driven cost zones

 Influence zones: including 10 pixel buffer zones for core areas > 200 pixels

 MSPA: showing spatial distribution and statistics for pattern, connectivity, and core areas of different size.

Morphological change detection: showing essential gainloss, unchanged foreground (dark) and background (light). 

Fragmentation: showing degree of fragmentation in percent.  

Landscape Mosaic: showing for each pixel the relative proportions of 3 classes (here: Agriculture, Natural, Developed) in a window surrounding that pixel.
