Site Recorder 4
Site Recorder 4 was developed from the original 3H software program called Site Surveyor which was developed to overcome some of the problems found when 3D surveying during archaeological fieldwork. Site Surveyor was completed during work on the Resurgam submarine in 1997 and was then used on many underwater archaeology projects all over the world. The complexity of site recording during the excavation of the Dutch East Indiaman Vliegent Hart in 2000 showed that there was a need for a single program that was capable of capturing all of the information about an archaeological site underwater. Site Recorder 3 was developed to fulfil that need and was used on a number of major projects including the Mary Rose excavations in 2003 - 2005. Site Recorder 4 is the next generation in this family of programs.
Site Recorder software has been used on many of the leading marine archaeological projects completed in recent years and is used by institutions, government organisations, commercial companies and universities in more than 23 countries. Site Recorder has also been used for mapping distributions for marine biology, inshore civil engineering, crime scene investigations and recording dinosaur footprints.
