Orthophoto Data Processing: Challenges and Solutions
Orthophoto data processing involves the creation of geometrically corrected aerial or satellite images that represent the Earth's surface in a planimetrically accurate manner. While the process has become more streamlined with advancements in technology, there are still several challenges associated with orthophoto data processing . Here are some common challenges and potential solutions: Image Distortions: Aerial or satellite images can suffer from distortions due to camera and sensor characteristics, relief displacements, atmospheric conditions, and other factors. These distortions need to be corrected to ensure accurate orthophoto generation. Solutions include using specialized software that can model and correct for various types of distortions, employing calibration techniques, and utilizing ground control points (GCPs) for accurate georeferencing. Georeferencing Accuracy: Georeferencing involves aligning the orthophoto to the correct geographic coordinates. Achieving...
