@article {5845, title = {Supporting Red List threat assessments with {GeoCAT:} geospatial conservation assessment tool}, journal = {{ZooKeys}}, volume = {150}, year = {2011}, month = {nov}, pages = {117{\textendash}126}, abstract = {{GeoCAT} is an open source, browser based tool that performs rapid geospatial analysis to ease the process of Red Listing taxa. Developed to utilise spatially referenced primary occurrence data, the analysis focuses on two aspects of the geographic range of a taxon: the extent of occurrence {(EOO)} and the area of occupancy {(AOO).} These metrics form part of the {IUCN} Red List categories and criteria and have often proved challenging to obtain in an accurate, consistent and repeatable way. Within a familiar Google Maps environment, {GeoCAT} users can quickly and easily combine data from multiple sources such as {GBIF}, Flickr and Scratchpads as well as user generated occurrence data. Analysis is done with the click of a button and is visualised instantly, providing an indication of the Red List threat rating, subject to meeting the full requirements of the criteria. Outputs including the results, data and parameters used for analysis are stored in a {GeoCAT} file that can be easily reloaded or shared with collaborators. {GeoCAT} is a first step toward automating the data handling process of Red List assessing and provides a valuable hub from which further developments and enhancements can be spawned.}, doi = {10.3897/zookeys.150.2109}, url = {http://dx.doi.org/10.3897/zookeys.150.2109}, author = {Bachman, Steven and Moat, Justin and Hill, Andrew and de la Torre, Javier and Scott, Ben} }
