Uaviation provides thermal mapping, inspection and survey solutions using UAV drone inspection services. Through simple oblique photography, complete GIS data sets or more complex 3D modelling, thermal maps of ground surfaces can be generated. The use of this technology is helping our clients monitor a range of asset maintenance and environmental issues. We use airborne GPS and IMU to optimise image collection, providing our customers with geospatially accurate 2D and 3D thermal maps.
The visualisation of thermal maps varies between application. Typically, the simplest 2D map form of visualisation is used for analysis purposes, however, thermal maps can be in 2D, 3D or even 4D as temperatures are mapped through time on a 3-dimensional surface.
Our sensors capture 2 million temperature readings per second. These readings can be stitched together to deliver survey ortho mosaics, complete with GPS encoding compatible with most GIS software suites. Thermal sensors are paired with a visual camera to allow for direct comparison between images. Our thermal mapping equipment is fully gyro stabilised and captures full radiometric images and video. This means that accurate temperature measurements can be taken from every pixel in the image.
Some applications for thermal mapping include:
- Mining and Oil & Gas
- Urban climate studies
- District Heating Infrastructure Monitoring
- Underground Pipeline Corridor Mapping
- Power Generation and Transmission
- Process Plants
- Drone Building Inspection
- Land use and thermal loading
- Solar Panel Inspections
- Irrigation Analysis for Agriculture
- Real Estate Drone Photography
- Wetland Mapping
- Water temperature assessments
- Bio-security and Feral Pest monitoring
Thermal Mapping for the environmental land management.
Uaviation’s thermal data capture and mapping service for land management allow for clients to monitor thermal loading across large areas. These areas can be over urban, rural or natural landscapes for the purposes of:
- Identifying thermal features such as feral animals or water birds for population monitoring,
Uaviation has conducted population surveys on Koala populations in the Mt. Eccles National Park. Thermal mapping was used by stitching images together along predefined sample points (transects). Counts were compared with those taken by ground-based methods. 50 percent more koalas were detected using thermal mapping than traditional ground surveys.
- Monitoring of thermal landscape characteristics and relationships such as urban heat characteristics,
Thermal infrared mapping techniques have been applied in urban climate and environmental studies, mainly for analysing land surface temperature patterns and its
relationship with surface characteristics, assessing urban heat island.
- Assessment of surface water temperature characteristics for the development of water assessments.
Rivers exhibit high spatial thermal heterogeneity that is difficult to understand using only in situ measurements. Thermal mapping of water surfaces can be used to characterise spatial and temporal thermal patterns.
Thermal Mapping for asset management.
Asset surface thermal characteristics can be mapped by stitching images together and projecting them over a 3D surface. Uaviation can produce fully radiometric 3D models of buildings and project sites as well as points of interest such as air conditioners and electrical transformers, thanks to our aerial drone photography.
This technology is especially useful in mapping thermal loading spatially. Uaviation has specific products made for large commercial roof inspection where differential thermal loading is mapped to highlight maintenance issues and component stresses.
Thermal mapping of building surfaces can inform building managers on the regions of principal heat loss. This information can be used to improve the efficiency of heating and cooling systems, resulting in significant savings on energy.
