NGS Releases Interactive Display of Survey Mark Information Page

Friday May 29, 2020

As part of the effort to modernize the nation's coordinate system, the National Spatial Reference System, NGS has released an interactive, beta version of its survey mark information page. Information about the locations and conditions of passive survey marks has historically been displayed online or in print as static NGS datasheets. The new mobile- and web-friendly BETA Mark Information Page color codes the GPS data for each survey mark based on the quality of the data, adds photographs of the mark and a map of its location, and includes descriptions and links to more information. NGS is currently seeking feedback on the usefulness of the page features and the ways users would like to interact with NGS datasheet information in the future.
