These software tools generally offer features like 3D model generation, point cloud creation, and the ability to produce geo-rectified outputs.
Detailed Explanation
Photogrammetry software tools have various functionalities essential for processing aerial imagery. They can create 3D models from multiple 2D images, generate point clouds that represent the surface of an area, and ensure that the outputs are geo-rectified so that they accurately reflect real-world locations. These features are crucial for accurate analysis and visualization of the surveyed areas.
Examples & Analogies
Imagine you're building a detailed model of your house using photographs from different angles. Each photograph provides a view of the house's dimensions, which when combined, help you create a precise 3D model. The software helps in stitching these photographs together, much like how you might use a scrapbook to piece together memories to create a complete picture.
