In Germany the Unemployment Agency uses a sectioning of the german map that is different from the usual Administrative Boundaries. Some demographic data are available in Administrative Boundaries only, some in Unemployment Boundaries only.
I would like to generate estimates in one boundary system of data availabe in the other boundary system, and would appreciate advice concerning the following questions: - can someone provide mapping functions between german Administrative Boundaries (Kreise, Gemeinden, ...) and Unemployment Boundaries (Arbeitsämter) OR - can someone provide polygon data of Unemployment Boundaries and/or Administrative Boundaries AND - is there a general function in R available to map demographic data between two boundary systems OR - is there an efficient R function that can determine the amount of area overlap between two general polygons (beyond gpclib) I am willing to share developed code for this problem (that's why I would prefer gpl code over gpclib, which is not really free) Thanks for any help Jens Oehlschlägel -- NEU FÜR ALLE - GMX MediaCenter - für Fotos, Musik, Dateien...
