Survey-grade coastal monitoring outputs for engineering assessment, planning applications, and long-term change detection programmes.
High-resolution aerial map of the survey area georeferenced to ITM coordinates – suitable for comparison against historical data to quantify shoreline change over time.
Cross-sectional profiles of cliff faces and shoreline positions extracted from the point cloud, enabling precise measurement of recession rates and volume loss.
Dense LiDAR point cloud of the coastal zone for detailed 3D modelling of cliff faces, beach profiles, dune systems, and nearshore infrastructure.
DSM and DTM of the coastal zone for flood risk modelling, storm surge assessment, and coastal infrastructure vulnerability analysis.
Quantified comparison between survey epochs showing volumetric loss, shoreline retreat, and areas of active erosion – formatted for planning submissions and environmental reports.
Scheduled repeat surveys at agreed intervals (seasonal, annual, or post-storm) using identical flight parameters to ensure consistent, comparable data across all epochs.
We provide single-epoch baseline surveys and multi-year monitoring programmes. Consistent methodology across every survey ensures your data is directly comparable over time – critical for planning applications and coastal management decisions.
Repeatable, survey-grade methodology that produces consistent data at every epoch for reliable long-term change detection.
For the initial survey we establish permanent ground control points (GCPs) at stable inland positions using RTK GNSS. These fixed reference points ensure every subsequent survey is georeferenced identically to within ±3cm, making cross-epoch comparison mathematically valid rather than approximate.
The drone flies a systematic grid pattern capturing overlapping photogrammetric imagery of the full survey area – cliff face, beach, dune system, and any infrastructure. Where LiDAR is included, a separate LiDAR pass captures the 3D point cloud. Flight parameters are recorded and replicated exactly at every repeat survey epoch.
Photogrammetric processing produces georeferenced orthomosaics and point clouds which are compared against previous epochs using GIS analysis. Shoreline position is extracted from each epoch and compared to quantify retreat rates. Volumetric change is calculated from DSM differencing across the survey area.
A structured change detection report documents shoreline positions, recession rates, volumetric loss, and areas of active concern – with annotated maps and cross-sectional profiles. Outputs are delivered in GeoTIFF, Shapefile, and PDF formats within 48 hours of the survey, ready for planning submissions, council reports, or engineering assessment.
High-resolution aerial orthomosaics, LiDAR point clouds, and coastal zone mapping for erosion assessment and planning documentation.
Repeat surveys tracking erosion rates, cliff recession, and sediment change along Irish coastlines.
