Key Differences Between LiDAR and Photogrammetry Scanning

While both LiDAR and photogrammetry are used to capture visual data, they operate in very different ways. Understanding their strengths helps you choose the right method for your Fort Lauderdale project.

LiDAR uses laser pulses to measure distance, capturing millions of points in precise alignment with the terrain or structure. Photogrammetry, on the other hand, relies on overlapping images to construct 3D models using software algorithms.

Here’s how they compare:

• Accuracy in poor lighting – LiDAR does not depend on light; photogrammetry does
• Speed and surface coverage – LiDAR is faster for large, complex areas
• Data quality on reflective surfaces – Photogrammetry may struggle where LiDAR does not
• Equipment cost and complexity – Photogrammetry may be cheaper, but less precise

LiDAR is typically the better option for technical applications that demand consistency, detail, and speed in challenging environments.
