Oblique imagery

Field is a leading supplier of oblique images. We capture oblique images from airplanes, drones and helicopters and use multiple custom oblique systems. 

One of our systems photographs image sets with five images simultaneously: one nadir image and four oblique images (forward, backward, right and left). The image sets are taken less than one second apart. Another system shoots with two oblique cameras (forward and backward) and one camera straight down while simultaneously performing laser scanning. This system is particularly suitable for detailed mapping and documentation of infrastructure such as railways.

Typical resolution or GSD (ground sampling distance) for the systems varies from less than 1 cm and up to about 15 cm, depending on the flight altitude. After collection, our team optimizes the images and performs digital post-processing where different lighting conditions and exposure settings are compensated for. This ensures that our images have good detail visibility and homogeneity in both light and shadow areas, and our customers receive a very high-quality product. Popular products include:

• Photorealistic 3D city models
• Detailed mapping of infrastructure such as railways
• Visibility solutions
• Façade images
• Terrain models based on image matching
  
  

Our customers can access their data through our online cloud-based viewing solution, Mapspace, directly through a browser or integration using a rich programming interface (API).
