Aerial Imagery: Aerial Imaging Solutions

Photogrammetry is the science of measuring and mapping points on the ground from several digital or hard copy photographs taken from different airborne perspectives.  

With aerial photogrammetry, users stitch these images together to create accurate, precisely detailed 3D representations of the topography and objects in a given area. Typical outputs include planimetric feature maps, contour line maps, and Digital Terrain Models. Planimetric feature maps show visible features on a flat surface, contour line maps display elevation changes, and Digital Terrain Models give a 3D representation of the Earth's surface — all instrumental in applications ranging from land surveying to urban planning and construction management.

Aerial photogrammetry’s many advantages include: 

• Superior spatial accuracy: Our imagery specialists calibrate focal length, principal point coordinates, and various forms of lens distortion to identify and correct systematic flaws in imagery data. 
• Rigorous insights: High-resolution aerial maps and imagery provide the necessary perspective to resolve disputes other technologies might produce.  
• Flexibility: Photogrammetry is a customizable aerial imaging solution. Based on a project’s requirements, we use metric film cameras to acquire panchromatic, natural color, or color-infrared aerial photographs and digital metric cameras to acquire multispectral digital imagery.
• Historical Value: Aerial photogrammetry is ideal for documenting and preserving cultural heritage, archaeological sites, or changing landscapes in digital format.  
• Efficiency & Cost-Effectiveness: Aerial photogrammetry leverages the power of computer algorithms to create 3D models faster and more affordably than manual methods.  
• Pectral digital imagery can be acquired from digital metric cameras. 

From working with aerial companies to produce the most efficient collection flight path, to choosing the appropriate aerial sensor for the task, a dedicated project lead will help you define your scope of work and ensure the entire project's success. 

The key to a successful aerial survey is accurately referencing the captured aerial imagery to ground control points, which must be visible in the aerial image data.

To provide superior coverage and meet horizontal and vertical accuracy requirements, we design the layout and placement of control points within your project area. We collect control points for most aerial projects unless directed otherwise — ensuring that every facet of your design is accurate and reliable.
