A new drone LiDAR mapping project from Ireland

A new drone LiDAR mapping project has been accomplished by Niall Gates from Ireland

Project Challenges presented: the highly vegetated area meaning that a DEM and contours created with photogrammetry wouldn't be accurate in these areas. A LiDAR survey could solve this but this brought its own challenge related to the topography of the quarried area. Standard terrain following (SRTM) with UgCS wouldn't be so accurate because the quarrying would've changed the topography of the land over time significantly.

Solution to perform survey job: photogrammetry mission flown and orthomosaic created while a basic DEM was also created (which was cleaned up a bit in highly vegetated areas). This basic DEM was imported to UgCS and flown according to with TOPODRONE LiDAR HI-RES on board of DJI M600 drone to create the final deliverables - highly accurate DEM and contours. The client will be using the final deliverables of the orthomosaic and the LiDAR DEM/contours as part of planning applications to develop their lands further.

Niall has been using TOPODRONE equipment since 2020, starting from the affordable and high-precision PPK module for DJI Phantom 4 Pro and now he operates drone based TOPODRONE LiDAR system.

Thank you Niall for the great photos and we wish you save flights and new interesting and challenging project!
