Dear list members, Does anyone know a working package for areal interpolation? I have 2 shapefiles (let's call them shapfile 1 and shapefile 2) for a country (with attribute table). They are from different time period, the boundaries change and I would like to calculate values from attribute table in shapefile 1 over boundaries from shapefile 2. The process is described here for ArcGIS (I found that the estimates it produced were not accurate): http://resources.arcgis.com/en/help/main/10.1/index.html#//0031000000q8000000 In the past I used pycno package written by Chris Brunsdon http://cran.r-project.org/web/packages/pycno/index.html but I see it is no longer maintained. Any ideas would be appreciated! Thanks, Juta
Can anyone recommend an areal interpolation package?

Hi Juta, You could try with the rtop package which also does area to area interpolation, but with a different method than the one used by ArcGIS. It was developed for a rather different use case (hydrological variables along stream networks), but should also be able to deal with data of the type you describe. Best wishes, Jon
