BANC3 has been performing field surveys including survey controls, aerial
photography, and topographic surveys for this 6-mile long project at Lower
Passaic River, NJ. Established horizontal and vertical survey control tied
to National Geodetic Survey (NGS) control monuments and tidal benchmarks.
Horizontal control was referenced to North American Datum of 1983 (NAD 83)
and Vertical datum referenced to Mean Low Water as related to the NGS tidal
benchmarks, NGVD 29 and NAVD 88. Accuracies exceeded the requirements of the
project.
Established 6 photo control points for the Passaic River project limits and 4 photo control points for the Koppers Seaboard/Standard Chlorine limits. Additional topographic surveys were performed along each side of the river’s edge to 100 feet out to supplement the aerial mapping and to locate utility crossings and bridge crossings. Locations were performed utilizing state-of-the-art total stations and/or Global Positioning Systems (GPS) Real Time Kinematic (RTK). An electronic drawing was prepared utilizing the locations to create a surface that was merged with Bathymetric Data. All layers and symbollogy followed the CAD standards of the NJ DEP for utilization in their Geographic Information System (GIS).
This has included graphical as well as non-graphic database population. BANC3’s mapping efforts ultimately resulted in a complete Geographical Information System (GIS) using the DEP GIS/Spatial Data Standards and Intergraph’s Modular GIS Environment.
