Hello all, and sorry for cross-posting, a script for the filtering of inaccurate relocation data has been developed in SAS by the USGS Alaskan team, and they wish to rewrite it in R. See below for more information.
best, Anne -- http://gis.cri.fmach.it/ghisla/ Begin forwarded message: Date: Tue, 8 Nov 2011 16:56:42 -0800 (PST) From: Anthony Fischbach <afischb...@usgs.gov> To: r-sig-...@r-project.org Subject: [R-sig-Geo] SAS to R translation help wanted Satellite data collection has revolutionized our understanding of animal movmement. Many relocations obtained by satellite data collection suffer large inaccuracies and must be filtered. Carla Freitas has contributed an algorithm for filtering such tracking data (http://cran.r-project.org/web/packages/argosfilter/). For years we have used on an alternative algorithm written in SAS (http://alaska.usgs.gov/science/biology/spatial/douglas.html). To better serve the wildlife tracking community, we wish to translate this Douglas algorithm from SAS and offer it as a function in the 'argosfilter' R package. For this translation effort we wish to contract help. Interested parties, please contact me directly. ----- Tony Fischbach, Wildlife Biologist Walrus Research Program Alaska Science Center U.S. Geological Survey 4210 University Drive Anchorage, AK 99508-4650 afischb...@usgs.gov http://alaska.usgs.gov/science/biology/walrus -- View this message in context: http://r-sig-geo.2731867.n2.nabble.com/SAS-to-R-translation-help-wanted-tp6976543p6976543.html Sent from the R-sig-geo mailing list archive at Nabble.com. _______________________________________________ R-sig-Geo mailing list r-sig-...@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo
