If there is one thing about land surveys that you have to know of, that would be the fact that they existed way back to the time when people started realizing the importance of holding their own land. When a land is being surveyed, surveyors are using specialized tools and equipments so that owners will know how wide, how, far, how big or even how small the land they have is that is why there are lots of land surveying tools created for such a purpose. Before the Middle Age, there were changes in the way land surveys are done that is why land surveying tools became out of fashion yet, upon the beginning of the Middle Age, these tools were once again brought back to existence and were used since then. During the Middle Age, the desire to hold a land was once again felt by the people of this day, aside from the fact that they want to know how much they own and want to protect the land that they own from others, hence, land surveying equipments were once again brought to existence.
If you are going to compare the land surveying tools and equipments used in the past with what we have now, you will see how they are very similar with each other, with the only difference being that the present equipments are touched with the latest technology. In this present day and time that we live in, with technology being in the middle of its heyday, every single equipments used for land surveys undergo drastic changes, and certainly, the computer is the one transforming this particular industry.
Now, that we have been mentioning about land surveying equipments being used then and now, we will now introduce some of them to you, beginning with what call as theodolite, one of the most popular and commonly used tool for land surveys. Even as recent as ten years ago, the theodolite, regardless of the fact that they were more technologically advanced, were still being used for the purpose of conducting a wide variety of surveys. Today, there are quite a number of improvements made for theodolites to make it more advanced and more functional that it was before and speaking of improvements, one of the greatest that it has is how it turned into an electronic equipment. And because of the many changes and improvements that happened on the part of theodolite, it also takes a different name which is now EDM or electronic measurement device (oftentimes referred to as total stations).
Another land surveying equipment that brought the industry into the age of computers is the GPS surveying. Speaking of GPS, this is an acronym that stands for Global Positioning System and is using satellite technology to do land surveying.
