Nordamerika

  • NOAA ENC (all)
    Over 500 S-57 ENC files from NOAA. These are all the current (Oct/2005) free ENC format Nautical charts for the USA. The charts are in S-57 format which can be somewhat challenging to exploit, but are readable using the OGR library as well as products such as FME, or the viewer software from SevenCs (http://www.sevencs.com).

USA

Gesamte USA

  • Punkte-Shape-Datei Geographischer Namen - 2 Millionen Punkte.
    About 2 million named places exist within US territory; everything from streams, churches, parks, mountains, etc. Of course they are all documented in a file format which is somewhat inaccessible to GIS applications. But using a nice bash shell script plus a python/ogr script, we can download all the wierd text files and convert them into one (huge) point shapefile.
    This data was processed by Matthew Perry.
