Oblique Imagery Surveys

Oblique imagery data captured via an aerial survey can be processed and then imported into viewing and measuring software such as OBLIVISION.

• The OBLIVISION Online Software is fully integrated with the ESRI platform
• It allows the direct overlay of ESRI shapefiles and ESRI database files
• Integrated with the ArcGIS server, users can simply launch the tool within the ESRI environment and visualise, analyse and map directly

Oblique imagery data captured via an aerial survey can be processed and then imported into viewing and measuring cloud-based software.

Oblique imagery data is very accurate. It is possible to make measurements using oblique aerial imagery survey data.

The oblique camera system is a calibrated metric digital camera.

• Geosense use the MIDAS 5 cameras system, coupled with the Applanix Inertial Measurement Unit (IMU), to capture oblique imagery during an aerial imagery survey
• The system is much like the large format Vexcel Ultracam digital cameras that we use for vertical imagery surveys, and captures oblique imagery with a very high precision geometric fidelity
• When applying ground control, we strive to achieve 2 pixel accuracy in the x,y,z RMSE across all 5 cameras

As with vertical imagery, the level of detail that can be seen on an oblique aerial image depends upon the camera used to capture the imagery during the survey and its Ground Sampling Distance (GSD).
