DIVA-GIS

DIVA-GIS is a free and open source geographic information system (GIS) to make maps of species distribution data and analyze these data.

di-GPS

RoboGEO

GPSphotolinker

 

GPSPhotoLinker can be used to save location and GPS position data to a photo. The latitude and longitude recorded by your GPS unit while you were taking photos can be linked, and saved, to the photos. GPSPhotoLinker automatically enters the city, state and country into the metadata.

Maxent

Maxent is a free software based on the maximum-entropy approach for species habitat modeling. This software takes as input a set of layers or environmental variables (such as elevation, precipitation, etc.) and produces a model of the range of the given species. It uses species georeferenced occurrence locations ( presence-only data) which makes it very useful for taxonomists.

DesktopGARP

DesktopGarp is a software package for biodiversity and ecologic research that allows the user to predict and analyze species distributions. GARP tries, interactively, to find non-random correlations between the presence and absence of the species and the values of the environmental parameters, using several types of rules. Each rule type implements a different method for building species prediction models. GARP as input takes enivonmental data and species occurrence localities. It generates random absence data.

Quantum GIS

Quantum GIS (QGIS) is a user friendly Open Source Geographic Information System (GIS) that runs on Linux, Unix, Mac OSX, and Windows. QGIS supports vector, raster, and database formats. QGIS is licensed under the GNU General Public License.

gvSIG

gvSIG is a tool oriented to manage geographic information. It is characterized by a user-friendly interface, with a quick access to the most usual raster and vector formats. In the same view it includes local as well as remote data through a WMS, WCS or WFS source. 



SEXTANTE

SEXTANTE is the GIS system developed by the government of Extremadura, for satisfying its own needs and continuing the line of technological advance that has been followed in the last years. You can visit it here : http://www.linex.org/).

GIS data downloads

 

Download of Geographic Information Systems (GIS) data layers.
Free GIS layers from different sources, in Idrisi and Shape formats, etc. to make easy download and use of this information.
Some GIS layers are still under construction, and the web page with links to the information is provisional.

deegree - Free Software for Spatial Data Infrastructures

deegree is a Java Framework offering the main building blocks for Spatial Data Infrastructures. Its entire architecture is developed using standards of the Open Geospatial Consortium (OGC).

R-sig-Geo -- R Special Interest Group on using Geographical data and Mapping

A mailing list for discussing the development and use of R functions and packages for handling and analysis of spatial, and particularly geographical, data. The list also covers mapping and cartographic issues, and interfaces between R and geographical information systems.

Open Source Geospatial Foundation

The Open Source Geospatial Foundation has been created to support andbuild the highest-quality open source geospatial software. Thefoundation's goal is to encourage the use and collaborative developmentof community-led projects. This website serves as a portal for usersand developers to share their ideas and contribute to projectdevelopment. As the Open Source Geospatial Foundation grows andchanges, so will this website. Please check back often and sign up tothe mailing lists to monitor developments. To get involved, check out the Getting Started page.

GPSBabel

GPSBabel is a converter program aimed at GPS systems. It can convert files to and from a large number of free and proprietary formats, such as KML (Google Earth) , csv, GPX, ...

HyperNiche

HyperNiche is a software for nonparametric regression, providing a flexible tool for multiplicative habitat modelling, habitat models where the predictors are combined multiplicatively rather than additively.

WhyWhere

WhyWhere is another modeling software similar to GARP that can detect strong associations with virtually any distribution type because it does not require assumptions about the form of the distributions such as gaussian, sigmoidal, exponential, etc, as an input.

JUICE

JUICE Determine species response curves on environmental gradients, allowing the determination of species optimum and also niche width (tolerance), and identifying species as generalist or specialist.

CLIMEX

A commercial package that enables to asses the risk of pest establishing in a new location and the potential success or failure of a biological control agent from the current locations.
