What it is?
Digital Orthophoto is a raster image generated by differentially rectifying scanned aerial photographs to compensate for distortions due to the altitude of the aircraft and the relief of the terrain. Digital Ortho photos combine the image characteristics of a photograph with geometric qualities of a map.
Digital Ortho photography provides an enhanced on-screen view of features not captured during traditional mapping operations.
Digital Ortho photography process rectifies aerial photographs to remove distortions caused by:
- The pitch and roll of the aircraft
- Radial distortion of the camera lens
- Image displacement due to terrain relief.
What we do?
Someshinfotech provides complete solutions for all types of digital orthophoto creation and orthorectification.
We do orthorectification of raw aerial imagery to remove the sensor and terrain related distortions from them. It includes the following inputs for processing, namely sensor information, orbital parameters, ground control, and elevation information. Geometric correction is done when there is inadequate information for orthorectification. In Geometric correction, sensor characteristics, orbital parameters, rational functions, or elevation information are not relied upon..
By employing a fine distribution of ground control points (GCPs) through the orthophoto generation process random errors of spatial data are adjusted. Ground Control Points (GCP) are collected from Global Positioning System (GPS) devices set in the field. In some cases GCP are referenced from an existing map. The GCPs are defined in a latitude and longitude coordinate system or in a projected coordinate system. Sensor attitude and orientation are generally corrected by taking into account both exterior and interior orientation parameters of the sensor or camera.
During Orthophoto generation, the "breaklines", GCPs and feature layers are included to ensure the positional accuracy and tonal quality of the Ortho photo. We do checks on the digital Orthophotos for any distortion, and positional accuracy, using the provided Orthophoto maps and surveyed ground control points. Flight height or AGPS data if provided as input, helps to achieve precision in the process.
