Four New Online Tools Provide Easier Access to NGS Data

After extensive testing though its Beta site, NGS is making the following four online tools available to the public as official products offered on the website:

  • DSWorld Web – enables users to submit updated information on survey marks available on NGS datasheets.
  • Leveling Project Page – simplifies searches for mark and observation information for an entire leveling project.
  • Calibration Baselines (CBL) Web Map – provides quick and easy access to the latest CBL information.
  • Passive Marks Page – for user-friendly datasheet access, including graphics, maps, and project information.
