iWitness is the easiest close-range photogrammetry program available for learning and building image-based measurements and 3D-models. iWitness was designed specifically for non-photogrammetrists. The program uses the most powerful and sophisticated features available but does so through a graphical-user-interface that is easy to use. The software program can be self-taught with the provided video demo example, users manual and easy-to-use Help Menu by anyone with basic computer skills.

If you are looking to "fast track" your understanding of iWitness or to develop a deeper understanding of its capabilities, please explore our training options discussed below.
