Pixpro Waypoints v2 - Orbitals and Height Offset for DJI Drones
Pixpro Waypoints is a service for consumer DJI drone users that provides consistent and automated flying for aerial photogrammetry purposes. For now, we had the essential single grid flight only, which is the bread and butter for making orthophoto images and terrain scans.

Overlap Between Different Perspectives
Photogrammetry can be simple and rigid or complex and adaptable. Combining different scan patterns adds complexity to the work but improves detail and coverage. We often use examples of combined flights, of which the orbital + nadir grid is a classic. They provide great 3D structure while being easy

RTK Drone Photos for Ground Control Points
Real-time Kinematic—RTK—is a GPS positioning system that allows for much greater accuracy than any regular GPS device. Consumer-grade GPS is quite sufficient for daily tasks such as navigation, tracking, and photo tagging, but when it comes to surveying, we need more accuracy.

Multi-battery Scans with Pixpro Waypoints
Pixpro waypoint service enables us to do grid flights with the best consumer-grade drones on the market. It is based on the current waypoint functionality, which has a limit of 101 waypoints. With a grid flight, such a limit means little.

Quad-Bayer Sensors - Impact on Image Quality and Photogrammetry
Quad bayer image sensor tech is quite common but not necessarily understood by consumers. We often mention that a drone or a smartphone camera has a quad-bayer sensor, so its stated resolution is not "real."

Commercial Roof Scan and Inspection
This blog post shares a real-world use case of a massive roof inspection job. The goal was to get a general scan of a commercial building roof for initial inspection and overview.

DJI Mini 4 Pro Photogrammetry - Pixpro Waypoints
DJI Mini 4 Pro is the best drone, weighing in under 250 grams, and thus, it avoids a lot of regulations that may be bothersome for some. However, it is also an excellent tool for professionals, many of whom may be interested in aerial photogrammetry.

Ground Sampling Distance Visualized
Ground sampling distance (GSD) is a ubiquitous term in photogrammetry. While this acronym often describes a specific scan quality aspect, it may be misunderstood or overvalued.
