GEO has made surveys throughout Denmark. You can search for them
in GEO's project base: Use "Google Search" (click the magnifier) to
find an address. Enter a city name or ZIP code to limit your
search, e.g. "Vinkelvej 4000" or "Vinkelvej Roskilde".
The result is red dots on the map in the requested area. Each dot
indicate that GEO's archive contains information about the position
and the date of the survey. GEO's activities could have been:
Geotechnical or environmental surveys, project tasks, or
drilling.
Contact GEO for more information about the project base.
