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.
The zip file below contains the SDMaps-programme with manual and examples.
