Constantly changing conditions in the world around us have created an awareness of the importance of an accurate, up-to-date understanding of our environment and resources. Sanborn orthophotography products and services deliver a suite of digital aerial photography products that provide geospatially accurate visual representations of the earth, and are useful for many mapping applications.

Sanborn owns and operates a fleet of aviation assets readily available for imagery acquisition at any U.S. location or abroad. Our inventory of digital aerial orthoimagery platforms includes three state-of-the art UltraCam Eagle sensors—designed to produce superior imagery for project areas of any size or scope. Leveraging proprietary aviation and acquisition assets, Sanborn produces authentic and accurate digital aerial imagery products while applying rigorous quality standards through every step of the process.

Sanborn Ortho products are produced by combining an area of interest’s digital aerial imagery with its respective digital elevation model. This is accomplished through the use of innovative software techniques, rigorous production processes, and comprehensive quality control measures. The resulting orthorectified image contains the image characteristics of a photograph with the geospatial qualities of a map. This facilitates the integration and sharing of data, promotes cooperative processes, and reduces the high-cost of duplication in database development.

CHOOSING THE RIGHT RESOLUTION

Sanborn Orthoimagery deliverables are available at various pixel resolutions, applicable for many different uses. Pixel resolution (pixel=a single point in a raster image) refers to the actual distance on the ground each pixel represents in the orthophotography. For example, a one-foot pixel resolution means each pixel in the image covers one foot on the ground. Common ortho resolutions include three-inch per pixel, six-inch per pixel, and one-foot per pixel. Higher resolution imagery delivers greater visible detail. Click here for more information about choosing the right resolution for your aerial photography project.
