Anchorpoint Geospatial delivers RTK-referenced photogrammetry that drops straight into Civil 3D as a TIN surface, with a dense point cloud for cross sections, profiles, and volumes. Tied to NAD83(HARN) Washington South (EPSG:2927) and NAVD88/GEOID18. For stamped deliverables we can partner with a Washington Licensed Professional Surveyor.
Civil and site engineering runs on surfaces. Topographic surfaces for grading and drainage, existing-ground surfaces for earthwork takeoffs, as-built surfaces for closeout. When those surfaces take weeks to arrive through traditional survey channels, preliminary design stalls, value engineering gets pushed, and the team makes decisions on incomplete data that get corrected later at a premium.
Anchorpoint fills the gap with RTK-referenced aerial photogrammetry. A single flight produces a calibrated dense point cloud, digital surface model, and orthomosaic, all tied to Washington State Plane and NAVD88. The outputs import directly into Civil 3D as a TIN surface, into OpenRoads, or into any CAD environment your team already uses.
Where the project requires a stamped survey, Anchorpoint can partner with a Washington Licensed Professional Surveyor. We fly and process the aerial data. The LPS handles the control, certification, and signoff. You get a clean deliverable without managing two vendors.
Dense point cloud and DSM derived from RTK-positioned photogrammetry. Imports to Civil 3D as a TIN surface without coordinate transformation. Ground sample distance tuned to project accuracy requirements, typically one to two centimeters per pixel.
High-overlap aerial capture for grade studies, access routing, laydown areas, and staging conflicts. Orthomosaic plus oblique imagery gives the design team a real picture of site constraints before CDs lock.
Repeat flights at identical mission parameters produce surfaces that can be differenced against the design TIN. Identify deviations, document closeout conditions, and support record drawings with measurable evidence.
For stamped engineering-grade deliverables, Anchorpoint can partner with a Washington Licensed Professional Surveyor on the control and signoff. One scope, clear separation between UAS operator and licensed survey responsibilities.
