SDMaps: Creating distribution maps from monitoring data and casual observations
Bird monitoring data are a very good of information to create distribution maps. Creating reliable maps from monitoring data and casual observations requires the use of advanced (geo-)statistical software. For this purpose we have developed SDMaps (formerly known as TRIMmaps). SDMaps is developed as a suite of scripts in the R-statistical language. The programme is still full in development, but can already be downloaded and used for distribution modeling.
In order to run SDMaps the open-source statistical programme R has to be installed first. The windows-version of R can be downloaded directly from www.stats.bris.ac.uk/R/bin/windows/base/release.htm. Users of other operating systems can download R from www.r-project.org.
