PHOTOGRAMMETRY

Imagine a drone flying over a site, capturing thousands of overlapping photos from different angles. When stitched together, those images create accurate 3D models and detailed maps. That is the power of photogrammetry.

Instead of laser pulses, photogrammetry relies on high-resolution imagery and advanced algorithms to measure depth and distance. By analyzing how objects appear across multiple images, it calculates precise spatial relationships and turns flat photos into detailed digital models.

Photogrammetry is transforming aerial data collection by creating accurate orthomosaics, 3D models, and elevation maps using imagery alone. It is especially powerful in large-scale mapping, infrastructure inspection, land planning, and agriculture. It turns aerial imagery into actionable insight, offering a ground-level understanding from an overhead perspective.

One Complete view

The value of advanced mapping lies in more than a single image. Multiple viewpoints and data layers allow teams to extract meaningful metrics from every project.

  • Orthomosaic: A seamless, georeferenced map created from thousands of overlapping images, accurate to real-world coordinates.

  • Visible (RGB): High-resolution aerial imagery aligned to scale, ideal for visual context and easy interpretation.

  • Digital Surface Model (DSM): An elevation model that includes buildings, trees, and other surface features.

  • Digital Terrain Model (DTM): A simulated bare-earth elevation model generated by removing surface structures.

  • Cut / Fill Analysis: A visual breakdown of material movement, showing where land was removed or added over time.

From elevation models to annotated overlays, these layers reveal critical details for planning, development, and review. Watch below to see a few examples of how we derive metrics from datasets.

PLAN AHEAD.

A smarter way to map: Photogrammetry gives you the clarity you need to make informed decisions. By capturing high-resolution aerial imagery and processing it into accurate orthomosaics and 3D models, we turn visuals into reliable geospatial data. It is a proven method for planning, measuring, and monitoring projects across construction, development, and land management.

Not a replacement — just a different tool: Photogrammetry and LiDAR are both valuable, but they serve different purposes. Photogrammetry is ideal for capturing visual context, surface detail, and accurate measurements when clear line of sight is available. LiDAR, on the other hand, uses laser pulses to penetrate vegetation and reveal true ground surfaces beneath. These tools are not in competition—they are often used together to provide a more complete picture.

Explore the possibilities: The video below shows how photogrammetry supports smarter project planning through multiple views, accurate measurements, and annotated overlays. From terrain evaluation to volume analysis, these tools help teams stay ahead at every stage of the job.
