An Oblique Photograph is a picture taken from the side of the aircraft at an angle to the subject rather than from directly overhead. Therefore, the aircraft does not have to fly directly over the area to be photographed. A high oblique does not shows the horizon; a low oblique does. A high oblique photo shows much more area than a vertical photo taken with the same focal length and from the same altitude; however, the images grow smaller toward the horizon.

A High Altitude Oblique (5000+ feet) is ideal for pictures of large areas or multiple lots giving the over all feel of a large area.

A Mid Altitude Oblique (1500 – 5000 feet) would scale down slightly from a high altitude oblique, focusing perhaps on a specific building or area with more detail, while still giving a view of surrounding lands or lots.

A Low Altitude Oblique (500 – 1500 feet) would focus much closer to a specific lot, building, or area giving great detail to a specific target within the picture. Detail of the surrounding area would be minimal.

By combining pictures taken at High, Mid, and Low altitude you can get a complete view of your lots, buildings, or properties.

An Orthophoto is an aerial photograph that has been corrected to remove distortion caused by camera optics, camera tilt, and differences in elevation, meaning that the photo can be considered equivalent to a map. Unlike an uncorrected aerial photograph, an orthophotograph can be used to measure true distances, because it is an accurate representation of the earth's surface. This enables the orthophotograph to be used as a backdrop onto which map features can be overlaid. This allows you to create a “digital” map using photographs of a wide range of buildings, land lots and other areas. However unlike traditional maps an Ortho Photograph gives you a true “bird’s eye” view of the area and various ground features.

An Ortho Photograph can be shot anywhere between 6000 feet to 8000 feet depending on what area or subject you want photographed, and how much detail you want. You can use multiple photographs taken at the same altitude to create a large “digital” map while giving you greater detail of the overall area.
