Sirior Hir Farm – UAV Photogrammetry & RTK GNSS Survey
Project type
LiDAR Surveying, 3D Terrain Mapping and GIS Analysis
Date
July 2026
Location
North Wales
Wren 3D completed a UAV photogrammetry and RTK GNSS survey across four fields at Sirior Hir Farm, Abergele. High-resolution drone imagery and ground measurements were combined to map field extents, physical features, terrain and vegetation.
The project produced detailed aerial maps, 3D terrain models, elevation and contour mapping, vegetation cover and height analysis, and predicted surface runoff routes. Field-by-field assessments calculated measured areas and estimated usable agricultural land, providing the landowners with a detailed spatial record to support land management and future decisions.
