GIS & Drone Survey

Geospatial Surveying & Drone Technology

Sefcom Environmental Consulting (SEC) delivers advanced Geographical Information Systems (GIS), remote sensing, and drone-based survey solutions that transform spatial data into actionable environmental intelligence.

We integrate high-resolution aerial data, geospatial analytics, and 3D modelling to support planning, permitting, operational optimisation, compliance monitoring, and infrastructure development. Our GIS and drone capabilities span the full project lifecycle, from baseline assessments and feasibility through construction, monitoring, and closure.

SEC combines spatial science, environmental expertise, and digital analytics to produce defensible, decision-ready geospatial outputs for mining, infrastructure, energy, water, and environmental projects.
