Assessment & monitoring support
Environmental
Environmental work stands on spatial evidence. SEC supplies the mapping, terrain and water data that environmental assessment, restoration and monitoring programmes are built on — with repeat surveys planned to support comparison between epochs.
Sector challenges
Environmental questions are spatial questions
No baseline record
Impact cannot be assessed against conditions that were never mapped.
Change that outpaces records
Erosion, drawdown and land-use change measured too rarely to support decisions.
Hard-to-reach terrain
Wetlands, waterways and disturbed ground where conventional access is limited or unsafe.
Fragmented datasets
Studies, imagery and field measurements that never come together into one queryable picture.
Project lifecycle
Baseline, monitor, verify
01
Baseline mapping
Topographic and aerial capture establishing site conditions before work or assessment begins.
- UAV & Aerial Survey
- Topographic Survey
02
Terrain & drainage modelling
Surface models supporting hydrology, drainage and erosion analysis by specialist consultants.
03
Water-body survey
Survey of rivers, marshes and reservoirs below the waterline where the assessment needs it.
- Hydrographic Survey
- Bathymetric Survey
04
Repeat monitoring surveys
The same areas re-captured on the same control to support comparison between epochs.
- UAV & Aerial Survey
- GNSS / RTK Survey
05
Spatial analysis & GIS
Field data structured into layers, change maps and analyses for reporting and review.
- GIS & Geospatial Solutions
- Spatial Analysis
06
Evidence for reporting
Maps, models and measured records supplied to the environmental consultants and authorities who assess them.
Technology approach
Measure lightly, document fully
Low-impact aerial capture
UAV mapping records sensitive or hard-to-reach ground from the air.
One reference frame
Monitoring epochs positioned on the same network control to support comparison between epochs.
GIS as the study record
Every epoch, layer and analysis kept in one structured, reviewable geospatial record.
Field equipment
DJI
DJI Matrice 300 RTK
A UAV platform of the type used to carry survey and inspection payloads, within the scope agreed for the project.
DJI
DJI Zenmuse L2
A LiDAR payload flown on a UAV platform to record ground and surface geometry as point measurements.
