For heritage surveying of highly intricate structures, Three Dimensional or 3D laser scanning is capable of capturing and scanning the irregular surfaces or features in very accurate detail. The recent application of LiDAR technology to heritage surveying provides the best and most efficient solution to conservation of cultural heritage and archaeological documentation.


Airborne LiDAR scanning is being used for heritage surveying all over the world. Not only this technology produces a more accurate measurement of building remnants, but it is also safer and faster to use. Conventional surveying of heritage sites such as ruins left by wars, historical buildings reclaimed by the forest, and old churches deeply covered by ashfall could impose danger on individuals conducting the survey. It also endangers the site itself, as human activities within a delicate historical structure may disturb parts of the site. Airborne LiDAR heritage surveying reduces the risk of endangering human life and disturbing historical properties of the site. Moreover, airborne surveying has been a great help in the field of archaeology across the globe.


Heritage surveying is not limited to airborne scanning. LiDAR technology has allowed archaeologists, engineers, and researchers to reach historical sites too deep beneath the earth to venture into. In some cases, LiDAR-abled drones are sent down catacombs and historical tunnels, their laser scanning ability provides experts with accurate structures of underground heritage sites. Aside from allowing experts to see underground structures, using LiDAR technology also lets them effectively store the data gathered by the scans and surveys.

Documentation and conservation of heritage structures are important for cultural preservation. This is better achieved when there is heritage surveying which displays fundamental spatial information needed for the work.
