Species Geocoder

The SpeciesGeoCoder software allows to plot species occurrences into polygons and more complex user-defined units (e.g. to know if the species are present in certain areas or study migration patterns). It can be used through the command-line, or through a simple graphical user interface. Basic documentation is provided through the project wiki.

The software accepts occurrence data in the format provided by GBIF.org.

SpeciesGeoCoder is a free software package written in Python and R, that utilise the GDAL library (http://www.gdal.org/) for fast analysis of geoTIFF files, which allows for the easy and fast coding of species into user-defined operational units. These units may be of any size and be purely spatial (i.e., polygons) such as political units (countries, states), conservation areas, realms, biomes, ecoregions, islands, biodiversity hotspots, and areas of endemism; but they may also be defined as a combination of several criteria, including altitudinal ranges. This flexibility allows scoring species into complex categories, such as those encountered in topographically and ecologically heterogeneous landscapes. The various outputs of SpeciesGeoCoder include quantitative biodiversity statistics, global and local distribution maps, and Nexus files that can be directly used in many phylogeny-based applications for ancestral state reconstruction, investigations on biome evolution, and diversification rate analyses.
