Ortho Imagery

Ortho imagery, also called orthophotos or orthorectified images, are aerial or satellite images that have been corrected for distortions caused by terrain and the angle of the camera or sensor when the image was captured. The process of orthorectification involves adjusting the image so that it appears as if it were taken from a vertical perspective.

Ortho photos are typically used for mapping and analysis purposes because they are accurate representations of the Earth's surface. Unlike traditional aerial photos, which may have distortions due to terrain and camera angle, ortho photos have been geometrically corrected to match a specified coordinate system. This means that each pixel in the image corresponds to a specific location on the Earth's surface.

Ortho photos are commonly used in a variety of industries, including agriculture, forestry, urban planning, and environmental monitoring. They can be used to accurately measure distances, areas, and volumes, and can provide valuable information for land management, disaster response, and infrastructure planning. Ortho photos are also used by government agencies for topographic mapping, geologic mapping, and resource exploration.
