Precision geodesy & land surveying solutions for the modern world
Get in touchDelta3 Geodetic Consulting is rooted in Colorado’s landscape. Founded and led by John Hunter, the National Geodetic Survey (NGS) Geodetic Coordinator for Colorado, we blend national‑level geodetic expertise with a deep understanding of local needs. John spearheaded the design and development of Colorado’s new State Plane Coordinate System as part of the forthcoming State Plane Coordinate System of 2022 (SPCS2022) modernization and personally designed most of the 36 zones that NGS plans to release in 2026. This modernization will replace the older NAD83 and NAVD88 datums with new terrestrial reference frames such as NATRF22, enabling highly accurate 3D positioning. As Colorado’s geodetic coordinator, John assits the state’s geospatial community transition from the NAD83 state plane coordinates to NATRF22 and provides training on using the new projections.
In addition to his geodetic work, John also specializes in due diligence land surveys. He examines properties for potential boundary conflicts, easement and right‑of‑way issues and other encumbrances so that clients can make informed purchasing decisions. Whether you need help navigating Colorado’s modernization efforts or require a thorough assessment of a property, Delta3 Geodetic Consulting delivers the expertise you need.
Leverage our experience in designing Colorado’s 36‑zone SPCS2022 to ensure your projects are ready for the NSRS modernization. We offer strategic guidance on establishing control networks, choosing appropriate map projections, and transforming datasets from NAD83 to NATRF22. We work closely with government agencies, surveyors and GIS professionals to minimize distortion and ensure consistency across the state.
From boundary and topographic surveys to construction layout, we provide comprehensive land surveying throughout Colorado. Our due diligence surveys identify boundary conflicts, easements, rights‑of‑way and other encumbrances that could affect property value or project viability. Combined with our knowledge of Colorado land records and state law, we help you mitigate risks before closing.
Precision is our hallmark. We perform rigorous processing and adjustment of GNSS and terrestrial observations, apply quality control and error analysis and produce high‑quality coordinates anchored to NATRF22. Whether you need network adjustments, baseline processing or transformation between datums, we refine your data to meet regulatory and scientific standards.
