MicMac is an open-source photogrammetric suite, licensed under Cecill-B, designed for a range of 3D reconstruction applications. While the software primarily targets professional and academic users, there are ongoing efforts to enhance its accessibility for a broader audience. One of its key advantages is its impressive versatility, allowing it to be applied across diverse domains such as cartography, environmental studies, industry, forestry, heritage preservation, and archaeology. MicMac facilitates the generation of both 3D models and ortho-imagery when suitable. It is capable of handling objects of various sizes, from small items and statues captured from ground level to larger structures like churches and castles using drone imagery, as well as extensive environments like buildings, cities, or natural landscapes through aerial or satellite methods. Furthermore, the software provides tools for georeferencing products in local, global, or absolute coordinate systems. Additionally, several supplementary tools expand its capabilities into metrology and site surveying, enriching its functionality in professional applications.
