There are several specialized software for photogrammetry, which could be used to analyze the 2D images captured by photogrammetric camera. Mapping or the surface creation process is also done with these photogrammetry software.
Detailed Explanation
Photogrammetric software is essential for analyzing images taken by cameras designed for photogrammetry. These tools help transform captured two-dimensional photographs into three-dimensional models or maps. This is a crucial step in mapping processes, where the software does the heavy lifting of analyzing and interpreting the images to recreate the physical surfaces and topography of the earth.
Examples & Analogies
Imagine a chef who uses various kitchen tools to create a dish. Just as a chef needs knives, pots, and pans to prepare a meal, photogrammetrists rely on specialized software to turn aerial images into useful maps and models.
