Hi everyone, I'm currently working on my PhD (geology) and would like to explore the possible GIS capabilities of R. I currently use ESRI's ArcView (3.x), ArcGIS (9.1), and ArcInfo (9) software for all of my GIS work. I have written an "extension" for the old ArcView that performs various analyses of points/polylines/polygons and have been wanting to update the extension for the latest version of ArcGIS to help me solve various research problems. With that being said, I discovered 'R' last year and fell in love with it and have been using it for data analysis of attribute tables from GIS Shapefiles. Ultimately, as part of my research, I would like to make a package for R that would handle various GIS tasks of shapefiles themselves, not just their data tables. It would be great to have a analysis package for my research that is not solely dependent on ESRI's software. Furthermore, I dread programming in Visual Basic for the new ArcGIS because I have limited programming skills. Here are some of the tasks I would like to perform:
- produce a new point shapefile that contains points where two or more shapefiles with polylines intersect - intersect two or more shapefiles with polygons and store the results in a new shapefile - calculate area of polygons - calculate the distance from a point shapefile to another point shapefile Is this possible in R, or, am I barking up the wrong tree? Thanks! cj _______________________________________________ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-geo
