Industry-leading aerial topographic surveys
APEM is a global leader in aerial topographic surveys. Clients from the water and power sectors, the construction industry and government agencies have commissioned us to undertake aerial surveys of sites of interest.
Using our specialist camera and image processing technology, APEM captures ultra-high resolution imagery – better than 5 cm GSD – in multiple wavebands from red-green-blue to near infrared. We use the data to generate high density topographic models such as point clouds, digital surface models (DSM) and digital terrain models (DTM), as well as accurate ortho-mosaics and 3D virtual flyovers.
The surveys are carried out by our expert team of pilots, technicians, project managers and image analysts, using our own fleet of survey aircraft and state-of-the camera systems.
Keeping the work in-house from start to finish means that we can ensure high quality data for our clients.
Benefits of aerial surveys
Our innovative approach to topographic mapping removes delays caused by land ownership or access issues and minimises the number of ‘boots-on-the-ground’, which is of significant health and safety benefit to our clients.
APEM’s aerial surveys also provide high quality data in remote, inaccessible or hazardous areas. In addition, we can survey either very large areas of up to 200 square kilometres or multiple small sites in a single day.
Topographic aerial surveys tailored to your needs
Our surveys are bespoke and can be tailored to meet your needs. For example, with our in-house processing techniques we can produce point clouds with up to 160 points per square metre – providing an unprecedented level of detail.
Our services include providing topographic data for:
- Earthworks volume calculation during construction projects
- Cut and fill analyses
- Catchment modelling – slope, watershed analysis and channel mapping
- Route optimisation analyses
- River restoration projects
- 3D visualisations.
