Drone Coastal Survey & Erosion Monitoring
Mauritius Coastal Conservation Agency (pilot project at Flic en Flac and Le Morne).
Services Used:
Drone Inspection & Environmental Survey
Orthomosaic Mapping & 3D Modelling
Data Capture & Change Analysis
Project Overview:
Rising sea levels and tropical storms are impacting Mauritius’ coastal integrity. The agency required accurate, repeatable surveys to assess shoreline erosion and sediment displacement.
TideWatcher Solution:
Deployed drones equipped with RTK GPS for centimeter-level mapping accuracy.
Captured high-resolution aerial imagery of beaches and coastal structures every quarter.
Created orthomosaics and digital elevation models (DEMs) for shoreline comparison.
Delivered analytics dashboards showing erosion trends and areas at high risk.
Results:
Enabled the agency to quantify erosion over time and plan targeted coastal reinforcement.
Reduced cost of monitoring by 50% compared to traditional surveying.
Data integrated into national GIS systems for environmental management.
Why Relevant to Mauritius:
Drone-based coastal monitoring provides sustainable and cost-effective insights for island nations vulnerable to sea-level rise.
