# This init file provides definitions for CH1903 and CH1903/LV03 # projections using the distortion grids developed by Swisstopo. # See: https://shop.swisstopo.admin.ch/en/products/geo_software/GIS_info # # You'll need to download the grids separately and put in a directory # scanned by libproj. Directories may be added to the scan list through # the PROJ_LIB environment variable # # Note that an independent effort was made to derive an usable grid # from the CH1903->CH1903+ grid initially available from the Swisstopo # website. You can read about this other effort here: # http://lists.maptools.org/pipermail/proj/2012-February/006093.html # It may be of interest because the latter was by some reported as being # more accurate than the former: # http://lists.maptools.org/pipermail/proj/2012-February/006119.html # # This init file uses the official one # <metadata> +origin=Swisstopo +lastupdate=2012-02-27 # CH1903/LV03 <1903_LV03> +proj=somerc +lat_0=46.95240555555556 +lon_0=7.439583333333333 +k_0=1 +x_0=600000 +y_0=200000 +ellps=bessel +units=m +nadgrids=CHENYX06_etrs.gsb +no_defs # CH1903 <1903> +proj=longlat +ellps=bessel +nadgrids=CHENYX06_etrs.gsb +no_defs <>
