Aerial Surveying

Providing Everything You Need

Aerial Surveying & Orthophotography

Accurate imagery. Clear deliverables. No surprises.

​

We collect 4‑band aerial imagery (RGB + NIR) and deliver GIS‑ready orthophotos that meet ASPRS accuracy standards. We use a mix of large‑format camera aircraft, Cessna 182, SR22, C172, and UAS where it makes sense. One team. One schedule. One point of contact.

What we do...​

  • Countywide orthophotography at 0.5 ft and 0.25 ft GSD

  • Ultra‑high‑resolution pockets down to ~0.125–0.083 ft GSD

  • RGB + NIR capture for 4‑band deliverables

  • Ground control planning, survey, and accuracy testing (NSSDA)

  • AT (aerotriangulation), seamline editing, radiometric balancing

  • Tiled GeoTIFF + file geodatabase, MrSID mosaics, FGDC metadata

  • Flight photo index and collection report right after acquisition

  • Plan. Flight lines, sun angle, overlap, sidelap. Ground control and AGPS/IMU plan.

  • Fly. Countywide blocks with a large‑format mapping camera. Use SR22/C172 for pilot, re‑flights, and small high‑res zones. Use UAS for gaps or tight airspace.

  • Control. GNSS/IMU processing, GCPs, checkpoints withheld for testing.

  • Adjust. Multi‑ray bundle adjustment. AT report out.

  • Ortho. Surface model check, orthorectify, seam, color balance.

  • QC. Tile edges, tone, geometry, accuracy. Fix. Re‑fly if needed.

  • Deliver. GeoTIFF + TFW and FGDB (LZ77), MrSID mosaics, metadata, logs, and index.

Why teams choose us

​

  • One shop, end‑to‑end. Flight, control, AT, ortho, QC, and packaging under one roof.

  • Practical scheduling. We plan for weather, holds, and ATC. We don’t promise what we can’t control.

  • Real QA. We test against withheld checkpoints and publish the numbers.

  • Straight talk. If a refly is needed, we tell you fast and fix it.

​

Example scope 

  • 0.5 ft countywide RGBNIR orthos and MrSID

  • 0.25 ft high‑res areas over urban/suburban corridors

  • Pilot area (~4 sq mi) delivered first to lock tone and method

  • Full package: AT report, tiles, MrSID, metadata, index, and collection report

​

Software we use

  • Flight planning/FMS and on‑mission QC

  • AGPS/IMU: POSPac or Inertial Explorer

  • AT: Inpho Match‑AT, SOCET GXP

  • Ortho/mosaic: Inpho OrthoMaster/OrthoVista, UltraMap, Geomatica

  • GIS + packaging: ArcGIS Pro, GDAL, GeoExpress (MrSID)

  • Metadata and QA tooling (tile joins, accuracy tests, reports)
