Re: [R-sig-Geo] Did I correctly convert my data from UTM zone 12 to 11?

in a common projection as for example EPSG:4326 or something like that. After that you can merge the two spatial objects in a single one or extract the new spatial coordinates to rewrite a new .csv file to be used outside R -- Maurizio Marchi, PhD Forest Science - Ecological Modelling
