Drone-fotogrammetrie: de complete gids
Wat drone-fotogrammetrie is, wat je ermee kunt maken en hoe je dronefoto's omzet in survey-grade orthomozaïeken, 3D-modellen, puntenwolken en hoogtemodellen.
Zo vlieg je een nauwkeurige drone-kartering (RTK + GCP's)
De branchestandaard voor survey-grade drone-kartering: overlap, GSD, gridpatronen, RTK/PPK-GPS (Trimble, DJI, Emlid), grondcontrolepunten en checkpoints.
Coördinatenstelsels & hoogtedatums voor dronemeting
Een praktische gids voor coördinatenstelsels en verticale/hoogtedatums voor dronekartering — met referentietabellen van Europese en Noord-Amerikaanse CRS (SWEREF99, ETRS89, OSGB, NAD83, State Plane) en hoogtesystemen (RH2000, NN2000, NAP, NAVD88, EGM2008).
Ground Control Points & Accuracy: A Surveyor's Guide
How ground control points work, how many you need and where to place them, GCPs vs RTK/PPK, checkpoints, and how to read a horizontal/vertical RMSE accuracy report for survey-grade drone mapping.
Best Drone for Mapping: How to Choose (2026)
How to choose a drone for photogrammetry and surveying — camera and sensor, RTK vs standard GPS, multirotor vs fixed-wing vs VTOL, and which drones suit which jobs.
Drone Volume Measurement: Stockpiles & Cut/Fill
How to measure volumes from drone data — stockpiles, earthworks and cut/fill — including base-surface choice, accuracy, best practices, and how to do it in Orthosite.
Drone Mapping for Construction: Progress, Volumes & As-Builts
How construction teams use drone mapping — progress tracking, earthwork volumes, cut/fill against design, as-builts and stakeholder communication — and how to do it accurately.
Orthomosaic, DSM & DTM Explained
What an orthomosaic, DSM, DTM, point cloud and 3D mesh are, how they differ, which to use for which job, and the formats they come in.
Drone Mapping for Agriculture: Terrain, Drainage & Planning
How drone mapping helps agriculture — accurate orthomosaics, elevation models for drainage and land levelling, area and volume measurement, and field documentation.
How to Measure on Drone Maps: Distance, Area, Volume & Profiles
How to measure distance, area, volume, height differences and cross-section profiles on a drone map — accurately, in the right units and coordinate system.
