Geospatial & Topographic Surveys
Terrain & Surface Models
Change Over Time
Geospatial survey services combine UAV aerial capture with structured processing methods to support mapping, monitoring, measurement, and survey-aligned data collection.
+ RTK-enabled capture and validation methods such as ground control points or checkpoints may be incorporated where required to support repeatability and accuracy verification.
+ These services are commonly undertaken to efficiently capture current site information across large environments while supporting consistent and repeatable data collection methods.
Operational Value:
+ Efficient site data capture
+ Accurate, repeatable records
+ Improved site visibility
+ Structured geospatial processes
+ Planning and reporting support
+ Terrain and earthworks monitoring
+ Compatible survey workflows
+ Consistent repeat survey data
+ Engineering and field outputs
+ Improved site documentation efficiency
Accuracy:
+ Validated photogrammetric surveying outputs
+ RTK-enabled aerial capture
+ GNSS-controlled UAV surveys
+ Survey-aligned engineering workflows
Accuracy validated using independent checkpoints (RMSE):
+ Vertical RMSE: ~5 cm
+ Horizontal RMSE: ~3 cm
This level of accuracy supports:
+ Volumetric calculations
+ Terrain and surface modelling
+ Repeatable site monitoring
+ Measurement and reporting workflows
