Photogrammetry Surveying

Image-based Reality Capture Services

Photogrammetry excels where surfaces are visible and visual detail matters.

High-resolution aerial mapping supported by survey expertise

Photogrammetry uses aerial imagery captured by drones to create accurate, measurable maps and models of a site. At Eagle Surveying, photogrammetry is used as a practical data-collection tool that supports planning, design, and construction—not as a standalone technology.

By combining drone imagery with survey control and professional oversight, we provide usable site data that integrates smoothly into engineering and development workflows.

What Eagle Surveying provides with photogrammetry

Eagle Surveying’s photogrammetry services focus on delivering mapping products that are accurate, clear, and ready for real-world use. Depending on project needs, deliverables may include:

  • High-resolution aerial imagery
  • Orthomosaic maps
  • 2D and 3D site models
  • Surface data for planning and design
  • Volumetric measurements for earthwork or materials

Which aerial method fits my project?

Choosing between photogrammetry and LiDAR depends on site conditions and how the data will be used. Eagle Surveying evaluates each project and recommends the approach that best supports accurate results and efficient workflows.

Photogrammetry is often a good fit when:

  • The site is open or already developed
  • Surface features are clearly visible
  • Visual detail and imagery are important
  • The project involves construction progress or volume tracking
  • Efficient coverage of large areas is needed

LiDAR is often a better choice when:

  • The site has heavy vegetation or tree cover
  • Accurate ground terrain is needed beneath vegetation
  • The property is large, undeveloped, or rural
  • Drainage, floodplain, or terrain modeling is critical

In some cases, a combination of photogrammetry and LiDAR provides the most complete picture of a site. Rather than relying on a single method, Eagle Surveying focuses on selecting the right tools based on real-world conditions and project goals.

Eagle Surveying’s role and expertise

Technology alone does not create reliable survey data. Eagle Surveying brings professional oversight to every photogrammetry project, including:

  • FAA-compliant drone operations
  • Survey-grade control and verification

  • Experienced data processing and quality review

  • Oversight by Texas-licensed Registered Professional Land Surveyors

This approach keeps photogrammetry aligned with surveying standards and project expectations.

Where photogrammetry surveying adds value

Photogrammetry is especially effective on sites where surface features are visible and visual detail is important, including:

  • Open or developed sites
  • Active construction projects
  • Large tracts requiring efficient coverage
  • Existing conditions documentation
  • Progress tracking and volume calculations

Using drones allows Eagle Surveying to collect data efficiently while minimizing site disruption.
