• It allows for the creation of accurate 3D models and orthophotos.

7. Describe the workflow involved in processing aerial photographs for mapping purposes.

The workflow for processing aerial photographs for mapping purposes typically involves the following steps:

• Image preprocessing: Correcting for radiometric and geometric distortions, color balancing.
• Stitching: Assembling overlapping images into a seamless mosaic.
• Orthorectification: Correcting for terrain elevation and camera tilt, creating a geometrically accurate image.
• Feature extraction: Identifying and extracting relevant features from the images, such as roads, buildings, and water bodies.
• Map production: Creating thematic maps or digital elevation models based on the extracted features.

8. How do you maintain and calibrate aerial photography equipment to ensure optimal performance?

To maintain and calibrate aerial photography equipment for optimal performance, the following steps can be taken:

• Regular cleaning and inspection of cameras, lenses, and other equipment.
• Periodic calibration of cameras to ensure accurate measurements and image geometry.
• Use of specialized software and tools for camera calibration and maintenance.
