Edzer Pebesma posted this Request for Comments to R-help and R-sig-Geo on October 31, 2003, informing that he has taken the initiative to develop an "sp" framework. The package development project is being hosted on SourceForge; access is also described in the posting. The package is available from CRAN.

aRT: R-Terralib API

aRT is an R package that provides the integration between the software R and the GIS classes TerraLib. The aim is to have a package for analysing spatial data in R.


Very rough notes based on the pre-DSC2003 meeting.



GeoXp

GeoXp is an R  package for exploratory spatial data analysis - the developers would be very grateful for feedback. There is a Windows binary package on the site, together with the R functions source files. The package: "is a tool for researchers in spatial statistics, spatial econometrics, geography, ecology etc allowing to link dynamically statistical plots with elementary maps. This coupling consists in the fact that the selection of a zone on the map results in the automatic highlighting of the corresponding points on the statistical graph or reversely the selection of a portion of the graph results in the automatic highlighting of the corresponding points on the map. GeoXp includes tools from different areas of spatial statistics including geostatistics as well as spatial econometrics and point processes. Besides elementary plots like boxplots, histograms or simple scatterplos, GeoXp also couples with maps Moran scatterplots, variogram cloud, Lorentz Curves,...In order to make the most of the multidimensionality of the data, GeoXp includes some dimension reduction techniques such as PCA."

Rmap

Rmap by Barry Rowlingson links against PROJ.4, OGR and shapelib. OGR permits many vector GIS formats to be handled. PROJ.4 projections and reading OGR data sources are now provided in CRAN package rgdal.

Rasp

Rasp is an initiative aiming to merge and develop point pattern analysis in R. Some of the aims of the initiative are described in this DSC2003 paper.

PostGIS

PostGIS shows integration of R and PostgreSQL through PostGIS.
