The Function of Land Surveying After a Natural Disaster

    Land Surveying After a Natural Disaster Helps Make Sense of Destruction

    It seems that wherever you are in the world, natural disasters strike in some form or fashion. Be it tornadoes, hurricanes, earthquakes, or snowstorms, the frequency and severity of natural disasters appear to be on the rise. In the aftermath of such natural disasters, homes and businesses can be destroyed and the land itself permanently changed. In fact, natural disasters can and often do alter property boundaries and create confusion for landowners. Land surveying is a way restore order to the chaos that is the aftermath of natural disasters.

    Aftermath of Disasters: Rebuilding

    In the event of a natural disaster, after relief efforts comes rebuilding. So how does land surveying come in? In the aftermath of natural disasters such as hurricanes, coastal land can be completely altered compared to prior to the disaster. The same goes for floods and earthquakes as well, the latter which upends property markers. Land surveying techniques such as distance measurement, angle measurement, levelling, position determination, reference networks, and datums have improved to include hardware and software that can minimize gross, systematic, and random errors. Through careful calibration, process consistency, and meticulous design of the reference network, accuracy and precision of measurements can be improved.

    Land Surveyors: What do they do?

    After a natural disaster strikes, the land could be completely different from before and require a change of use. How so? Well, in the event of an earthquake triggering a landslide, the original property could be unsafe for any rebuilding and have other associated risks now. Land surveyors can help develop a redistribution plan in such cases that is fair for everyone involved.  Primarily, land surveying helps restore normalcy to property owners through mapping and re-establishing property boundaries. In addition land surveyors can offer assistance in conflict management and resolution, land tenure issues, and property right protection.

    Land surveying is not restricted to natural disaster aftermaths. Perhaps the most common application of land surveying is to map out in 2D and 3D the terrain in order to generate the information necessary for developing a residential or commercial property. With a combination of traditional hardware and modeling software, land surveying can help generate a complete 3D map of the area of interest.

    Land surveying involves elements of geometry, statistical analysis, engineering, and physics. In order to combine the necessary technical disciplines, equipment such as 3D scanners and GPS receivers are used in addition to dedicated surveying software. Most forms of construction require land surveying, everything from transport and communications to mapping of legal boundaries.

    In a time where the physical world around us is being frequently reshaped, land surveying is even more applicable and critical. If you want to learn more about land surveying and the tools and services we offer for your project, contact cadsourcing today to get started.
