A bluebook survey is a GNSS or leveling survey performed to certain
specifications which is formatted and submitted to the National Geodetic Survey
(NGS) for inclusion in the National Spatial Reference System (NSRS). Terrasurv
has performed dozens of GNSS bluebook surveys ranging from a single station to
countywide networks of more than 400 stations, as well as providing processing
and adjustments for submittal of projects observed by other agencies and
companies. Leveling projects from a single reset station to a 130 mile second
order level run and subsidence monitoring projects have also been submitted.
Example Project: USACE Pittsburgh District Reservoirs CEPD Survey-The
Pittsburgh District of the US Army Corps of Engineers needed to have an NSRS
station on each of their sixteen reservoirs to meet the requirements of the Comprehensive
Evaluation of Project Datums required after Hurricane Katrina. This project
established an accurate (±0.03 m NAVD88) elevation at each project.
