Plugins “quality”

Presentation

Several plugins concern the “geoxygene-quality” module :

• « PlugInEstim » : this plugin concern the EstIM model developed during the PhD of (Girres, 2012). Allows the computation of different impacts (projection, terrain, polygonal approximation, digitizing error, generalisation) for lengths and areas.
• « PlugInComparison » : a plugin to compute differences between datasets. Automatic or manuel matching are provided for polygons and linestrings. Different methods to normalize linestring comparisons are also proposed (extremity cutting, section cutting)
• « PlugInMountainGridDetection » : a plugin to facilitate the delineation of mountainous areas
• ...
