9 articles on Pix4D. Field-tested methodology from a GIS scientist with M.S. GIS, FAA Part 107, and 10+ years of geospatial work.
Image overlap drone mapping: 75/60 is the floor, not the target. Here's what fails when overlap is wrong and how to set photogrammetry overlap by job type.
The drone mapping quality report looks reassuring — until a client finds 8-inch errors. Learn to read every Pix4D and Metashape number before delivery.
GCP residuals measure fit, not accuracy. Drone survey checkpoints provide independent validation. How to set them up in Pix4D, Metashape, WebODM.
Fly a grid mission with a consumer drone, process a georeferenced orthomosaic in WebODM within 90 minutes. No GCPs, no survey gear, no paid software.
Free WebODM vs paid Pix4D for consumer drone imagery: orthomosaic quality, accuracy, real cost math, and exactly when each one is worth it in 2026.
WGS84 vs NAD83, state plane, vertical datums — the CRS settings drone operators get wrong, and how to fix them in Metashape, Pix4D, and ODM.
WebODM vs Pix4D vs Metashape vs RealityCapture: pricing, speed, accuracy, and GCP workflow compared — and which one wins for survey-grade work in 2026.
PIX4Dmatic 2.0 absorbs PIX4Dsurvey into three tiers. Full comparison vs Metashape and DJI Terra on price, accuracy, GCP workflows, and deliverables.
