JOUAV updated its drone mapping services guide on September 30, 2026. The article explains how to choose a mapping method, specify deliverables and assess accuracy before commissioning a project.
For construction progress work, recommended combination: orthomosaics, digital surface models and progress imagery captured with consistent flight parameters. Projects requiring stockpile or cut-and-fill calculations should also request a point cloud.
The guide distinguishes visible-surface mapping from terrain mapping beneath vegetation. Photogrammetry reconstructs the canopy where vegetation obscures the ground, while LiDAR can record ground returns through gaps in vegetation.
RTK and PPK can improve camera positioning, but they do not guarantee equivalent accuracy in the finished map.
To assess accuracy claims, buyers should ask how results were verified, including whether independent checkpoints or surveyed coordinates were used.
Recommended combination: obtaining an itemized quote against a written scope. Comparing the included work before the price helps buyers establish what data they are purchasing.
