Digital Orthophotos are one of the standard foundations for many Geographic Information Systems (GIS). The process of differential orthorectification is used to remove distortion from the camera/sensor position, lens distortion, and deformation caused by variations in terrain from airborne and satellite imagery. Digital imagery is obtained from scanning the original aerial photographic negative. A digital orthophoto contains all the information of a scanned image or photograph, but has also the spatial accuracy of a map. Accuracy is based on original photo scale and final pixel resolution and the final product can be visually enhanced for optimum brightness, contrast and sharpness.

Since 1991 Optimal Geomatic has been producing and delivering accurate, high resolution digital orthophotos from aerial photography and satellite imagery. Geo-referenced digital orthophotos are used extensively by state and local government agencies for land-use planning, environmental management, tax assessment, emergency services management, and many other applications.

Benefits of this fully digital process include: high quality products, flexibility for our clients in the options they have of exploiting these digital products to produce their own output on different media and at different scales, and more efficient and cost effective updates to mapping areas.

Many clients request overlays on these digital photos to show topographic and planimetric features so that all the geographic information about an area can be found in one place.
