Find-A-Control allows surveyors, field personnel, and interested citizens to access National Geodetic Survey (NGS) survey control information through a mobile device. The NGS serves as the United States’ repository for geodetic data and provides the public with information on geodetic control stations maintained by the NGS within the US and trust territories. Further information on the data used in Find-A-Control can be found on the NGS website at www.ngs.noaa.gov.

Enabling field personnel to easily access NGS data on-the-go through their mobile devices provides easy access to information needed by users while in the field and eliminates trips to a connected location when control cannot be found. Find-A-Control provides users the ability to quickly and efficiently view survey control stations on a map, identify the quality and type of stations, and view NGS datasheets that summarize key geodetic information stored in the NGS database.

Key features include:

• View NGS survey control stations in a map viewer

• Toggle on/off layers used to identify station quality/type, i.e., horizontal, vertical, combined, low quality and Continuously

   Operating Reference Station (CORS) Network

• Switch easily between Streets or Imagery basemaps

• Search by County

• Zoom to current location

• View station summary information with map callouts

• Direct access to NGS datasheets that summarize key geodetic information
