If you missed the NGS online Webinar for Feburary 16th’s NGS/DS World for Survey Control in Google Earth. 

The video is now available online and you can download it too.

Not only is the tool useful for finding NGS Survey control points and viewing them in Google Earth here are some other added features:

Description: DSWorld was originally designed to display datasheet information in a “world view”, hence its name. Since its inception, it has been greatly enhanced to the point of being a major interface with NGS and the NGS Integrated Database (IDB). It provides Land Surveyors, GIS professionals and the general public with important up-to-date geodetic control information at the click of a button.
