Should we use the point data from Preuss, which is published in the CRC database?
Preuss is in Lat/Long (ellipsoidal coordinates). Would have to be converted.
Alternativ: Some data from the archdata-package in R?
There is not suitable sample data set in archdata.
There seems to be a column with UTM-coordinates (UTM 32N?) in the SFB 806/Preuß data.
Code-Snippet to load SFB 806/Preuss data from web:
data <- read.csv(url(url_link))
data <- SpatialPointsDataFrame(SpatialPoints(cbind(data$RECHTS, data$HOCH)), data, proj4string = CRS("+init=epsg:25832"))
proj4string(data) <- CRS("+init=epsg:25832")
proj4string(data)
data `
Has been implemented!
Distances to nearest neighbor are suspicious small in the sample data set:
over 600 sites with nndist smaller 100 m!
Should we include sample data into the compendium? If so, should it be real or generated data?
