Predictive distribution maps are presented according to projects. All maps are in geo tiff format and in L-Est coordinate system (parameters of L-Est can be found here). The geo tiff format contains coordinates and the maps can be combined with other data layers in most common geo-info software packages (ArcGIS, MapInfo and MicroStation). Location of the mapped area and legends are given by projects.

Predictive distribution maps from this project indicate sites that, according to remote sensing and cartographical data, are more similar to locations where the target species has been registered compared to locations, which were visited but the species was not found. Exemplar locations and appropriate locational features were selected by software Constud. The same software was applied for calculating predictive maps.

Observation data (both movement tracks and species records) collected in 2004-2008 were used. Data from August 7th, 2008, which were occasionally left out in Remm and Remm (2009), were included into calculations of map series 05. 2009, which is based on additional iterative search for the best predictive set of features and exemplars using Constud. Almost identical source data can yield in rather different though almost equally reliable predictive maps.

In addition to predictive maps, the software Constud calculates certainty maps indicating similarity between a predicted location and the exemplar locations used for prediction.
