Land surveys today benefit from hundreds of years of experience, knowledge, and tools. Our map creation of today uses anything from magnetic locators to special telescopes, to drones and satellites. The men tasked with early land surveys had simple equipment and employed special and innovative techniques to get the job done. As we saw in our series about Lewis & Clark, some of America’s most notable land surveyors, these early pioneers didn’t have much to work with but their knowledge of the land propelled them forward. Land surveys rely on smart techniques but also on their tools to get the job done.
Early Tools and Techniques for Surveying and Understanding the Land
Even ancient peoples had the urge and necessity to understand the land that surrounded them. It is an essential part of civilization—though not often discussed as such.
The Roman Groma
One early instrument in the history of land surveyors seems to have made its way from Mesopotamia. The Groma looks rather simple. It is a vertical staff with horizontal staff pieces at right angles. It was also adopted by the early Romans to measure land in the empire for taxation purposes.
The Greek Diopter
With the advancement of math and geometry came advancements in other fields. Land surveying advanced as the art of measurements and mathematical equations developed further. The Greeks developed the diopter. This was a lightweight portable tool composed of a cogwheel. They used water levels and astronomical features to survey a property. The theodolite—an instrument still used today— seems to have derived or at least been inspired by the early Greek diopter.
Land Surveying in Early Europe and American History
As Western civilizations expanded, the need to understand and record features of the land became more and more important. As the British Empire extended its borders across great lands, the explorers that led these expeditions sought to understand the lands in which they ventured.
In 1571, Joshua Habermel created the first theodolite. Modern versions of this tool still exist today and form part of the day-to-day surveyors kit. This is a precise instrument that requires a tripod and compass. When early Europeans began using the technique of triangulation, it improved the accuracy of the measurements of boundary lines. This early European method of triangulation was used up to the 1980s because of its simplicity and accuracy.
The Use of Celestial Maps & the Night Sky
In the mid 18th century, the theodolite was improved by the addition of a scope. Today’s Theodolite, for example, is a rather sophisticated telescope derived from these early versions. Surveyors around this time used sextants, which measured angles using celestial maps.
The Use of Other Early Tools
The land surveyor’s tool kit has evolved but the ideas have remained the same. Below is a list of various other early tools used by pioneer land surveyors that learned to be creative and innovative with what was at hand.
- Gunther’s Chain: This tool was around during the 17th century. It is a thin-looking chain consisting of a linked chain that is pinned to the ground and extended outward up to 60-65 feet. It helped surveyors define a path and record measurements from endpoint to endpoint.
- Gunter Surveyor Compass: Angles are critical for land surveys. Many of the tools that were developed early on focused on using angles to measure distances and terrain. Also known as the circumferentor, this tool helped determine right angles.
- Zenith Telescope: This is a refracting telescope and was pretty sophisticated for its time. It was designed to observe the night skies and contributed to the understanding of Earth’s rotation and axis. Portable versions of this telescope were used for land surveys including latitude determinations.
- Ramsden Theodolite: Jesse Ramdsen developed the Ramsden Theodolite in the late 1700s. He was an innovative London instrument maker that was tasked with creating an accurate instrument that used triangulation to divide England. The instrument weighed up to 200 pounds.
The Day-to-Day Instruments Used for Land Surveying Today
Most days it depends on the job. When surveying relatively flat terrain in the middle of a city to surveying mountain regions or deserts, there are various instruments and equipment that can be used. On any given day you might find your local land surveyor using the following:
- Surveying magnetic locators
- Surveyors safety vests
- Surveying tripods
- Marking paint
- Automatic levels
- Total stations
- Electronic levels
The list goes on. Depending on the kind of job and the kind of survey that needs to be done, the tool kit may vary slightly.

Surveying and map-making began as a treacherous and rather dangerous enterprise. It wasn’t for the faint of heart. Lewis and Clark were one of history’s most important land surveyors. They and their crew would be responsible for changing the course and expansion of America. In our last post, we explored the background of Lewis and Clark and some of the surveying tools that they would take on their journey. Today we continue our remembrance of this historic expedition and the surveying marvels that were born from this trek across unknown lands.
Two Surveyors, a Guide, & Thousands of Miles
In addition to their early surveyor tools like compasses, quadrants, telescopes, and chronometers, Lewis and Clark also gathered other necessary equipment. Some of these included weapons and ammunition, medical supplies and medicines, books on botany, geography, and astronomy, maps, as well as gifts to present to Native Americans they knew they’d run into including beads, face paint, ivory combs, and more.
The duo recruited 45 brave souls to join them on their way westward. Among these were 27 unmarried men, a French-Indian interpreter, a boat crew, and Clark’s slave known as York. One other unique characteristic about the Corps was the fact that it was a rather eclectic and diverse bunch. In addition to the Southern roots of Lewis and Clark, there was his slave, a one-eyed-part-French-part-Omaha-Indian fiddler player, a German named John Potts, and the famous Sacagawea, a Shoshone Indian.
Both Lewis and Clark knew the journey would require incredible tenacity and discipline and so they ran a tight ship.’ Historical accounts describe how the corps was led with an iron fist, including harsh punishments like bareback lashing and hard labor for dissidents or uncooperative members of the team. It is the ultimate adventure story, only one person of the crew would die during the journey—a 22-year-old who died of an abdominal infection.
The team headed northwest along the Missouri River. Thomas Jefferson tasked them with several missions and goals for the expedition. These included finding and mapping a route across the continent, making detailed observations and notes regarding the natural geography, landscapes, and natural resources out West. At the same time, the team was meant to establish good relationships with native peoples along the way to interrupt the British dominance of the fur trade in the areas.
By mid-October, the expedition had reached the Mandan villages on the Missouri River. This important trading place allowed them to make some connections and talk to others about possible routes westward. The team had moved to South Dakota, North Dakota, and Montana. From the Mandan Villages, the crew was now facing the Rocky Mountains, the highest mountain range. One famous story was of Merriweather Lewis falling 20 feet into a cavern, was poisoned, and then shot in the thigh.
The now-famous Sacajawea, the wife of one of the Frenchmen in the expedition, proved to be invaluable for the success of the journey, as her language skills and knowledge of the territory proved essential. By the winter of 1805, they had reached the Columbia River and made a transcontinental crossing north of Mexico.
By the end, the expedition has traveled about 8,000 miles while pushing, pulling, and hauling ‘the boat’, the famous keelboat of the Corps, facing harsh storms, weather, hunger, thirst, and one or two run-ins with bears, friendly and not-so-friendly Indians, exhaustion, sleeplessness, mosquitoes, venereal disease, dysentery, boils, ticks, injuries, and God knows what else. The crew also found themselves face-to-face with some elk, buffalo, and deer, which they kindly turned into campfire dinners.
Throughout the trek, many of the men kept detailed journals, which would serve them well, as many of the maps and drawings they tried to send back to Jefferson during their journey never made it through. Finally, the crew made it to the West Coast, moving through northern Montana, Oregon, and present-day Washington onto Ft. Clatsop.
The Land Surveyors Return Home to a Hero’s Welcome
When Merriweather Lewis and William Clark returned to St. Louis with their crew, they were celebrated as pioneers and heroes of the time. The crew arrived back in St. Louis in September. The Corps of Discovery go their own way, but Lewis is named governor of the Louisiana Territory, while Clark becomes an Indian agent for the West. Most of the intended goals of the journey were met. This included establishing diplomatic relationships with Native Americans. The crew held councils with Indians and participated in events with them. Upon his return, Lewis had identified 178 plants including bitterroot, prairie sagebrush, Douglas fir, and ponderosa pine. They had also identified 122 animals such as grizzly bears, prairie dogs, and pronghorn antelope.
A Tradition of Land Surveying Continues With Unprecedented Precision
Lewis and Clark’s journey is seen differently among historians. For many, the journey was one of the first tales of American exceptionalism and would spearhead a movement of westward expansion and discovery. Others focus on the tragedies that plagued the journey. In the end, the expedition’s contributions to early maps of American territory are indisputable. The flourishing country understood its terrain and natural resources much more in-depth than it did before 1804.
As land surveyors, we can only admire the skill and technical understanding of Lewis and Clark in their creation of maps. Their understanding of geography, astronomy, and climate, allowed them to make extraordinary conclusions that turned out to be quite accurate.
While the process is much different today, here at Land-Mark Land Surveying, we move forward with creating detailed and accurate land surveys for construction, government contracts, and more. Connect with us to find out more!
Since 1991 Land-Mark has been at the forefront of the land surveying industry. A lot has changed since 1991, of course. In the early nineties, very few people could imagine that their cumbersome beepers would be transformed into sophisticated mobile devices capable of helping them navigate unknown territory (figuratively and literally), facilitate immediate communication across the globe, provide up-to-date news, take decent photographs, and store hundreds of bits of information. Similarly, technology has found its way to land-surveying and other relevant industries, providing equipment that increases accuracy and efficiency.
We use a variety of equipment, depending on the specific job, land, and project at hand. One of our trusted partners includes the company TopCon. These guys are highly innovative and perfectionists in developing new systems and equipment to improve the construction and planning of infrastructure and land planning. Topcon provides the positioning technology for surveyors, civil engineers, construction contractors, equipment owners, and operators. The geospatial solutions from Topcon have the most in-depth precision measurement for land mapping and surveying.
The Use of Digital Systems in Construction, Infrastructure, and Mapping
As land surveyors, Land-Mark is at the opening stages of a construction project. We form, however, part of the bigger picture that is all infrastructure building and construction. The use of technology in all stages of the construction industry has improved construction’s accuracy, safety, and efficiency.
In 1927, as TopCon points out, the world had 2 billion people. Only about one hundred years later did that number rise all the way to 7 billion. This means thousands of more acres developed, millions of more buildings erected, hundreds of more cities extended and expanded, and a constant and consistent demand for better and smarter building solutions.
A Few Amazing Examples….
Building great structures has always come at a human cost. There is not only a demand for human toil and labor but a high risk of accidents and injuries in any construction site. Any great building or structure you can think up has come at a cost of human lives. Some projects have been more successful than others. The Golden Gate bridge, for example, had 11 laborers died, a neighboring bridge, the Oakland Bay Bridge, had 28 people die in its construction. The World Trade Centers had 60 construction deaths. Recent technology, however, has allowed engineers to survey an area using drone technology without putting human lives at risk. A TopCon project to repair the Great Wall of China would have required workers to traverse a dangerous area. Instead, they sent a drone that was able to take thousands of high-resolution images that could then be input into a 3-D model, that was then used to examine the area and determine what needed to be done.
Measurement instruments have improved the ability for land surveyors like ourselves to enhance our workflow and improve our accuracy. Another great thing that technology offers is that added guarantee of accurate measurements and absolute efficiency. Land-Mark personnel is trained in a variety of high-tech and highly-specialized equipment that will ensure the proper mapping and measurements of your land project.

Here’s a fun fact for you, did you know that three of the four presidents immortalized on Mount Rushmore were land surveyors? It’s true. George Washington, Thomas Jefferson, and Abraham Lincoln were all proud of land surveyors. It’s a beautiful thought; these men who basically build the America we know and love today also played their part in literally surveying America’s own land. The importance of land surveyors goes as far back as history immemorial. If you’re looking for land surveying assistance in the Southwest region, give Land-Mark Professional Land Surveyors a call!
What Goes Into Land Surveying
Although there have been many advancements in modern technology that have made land surveying as accurate as possible, the basic tenets of land surveying are the same as they were in Washington’s day. The measuring of properties and land in order to determine boundaries is as important in this day and age as it was back when the Louisiana Purchase first went through. Let’s say you purchased some land and you plan to develop said land. Before doing so, you must have it surveyed by a professional land surveyor. Avoiding this can lead to many issues in the future.
The Right First Step
Just imagine, you buy land, develop it, and build a shopping center over it. Then, a few years later, you find out the person who owns the plot of land adjacent to yours wants to develop it as well and a land surveyor determines you built on the neighboring land. This will undoubtedly lead to litigation and other legal issues you’d rather avoid. So, before breaking ground, hire a land surveyor. With their findings, you’ll be able to take the first steps towards building whatever you may have in mind. Even if you’re not currently planning on developing your land, it’s still a good idea to have it surveyed. This information will be incredibly useful, no matter what you plan to do with your land.

Let’s transport ourselves to middle school history class. Do you recall the term “manifest destiny?” This was a 19th-century belief that the United States had a destiny (appointed by God) to expand across the entire North American continent. This was much more than a physical expansion of the nation; it was an expansion of the democracy and capitalism that was the foundation of the United States. Manifest destiny was much more than a belief, as it became a reality rather quickly. The Louisiana Purchase in 1803 doubled the size of the young United States, kicking manifest destiny into gear. Soon afterward, the famous Lewis and Clark expedition took place. Meriwether Lewis and William Clark were both land surveyors (amongst many other things) so they were the perfect candidates for such an expedition. This is just one example of the importance of land surveyors in America’s history.
How the Dominion of the United States Spread from East to West
The United States acquired large parts of Mexico in the early and mid 19th century. By 1846, we acquired the Oregon Territory thanks to a treaty with Great Britain. By 1850, the United States had grown to the size it is today. Fewer than 100 years after we declared independence from England, the United States ostensibly quadrupled in size. This is where land surveyors came into play. With so much land available, it was necessary for land surveyors to document each piece of the new America. Many land surveyors actually went on to become presidents of the United States. George Washington, Thomas Jefferson, and Abraham Lincoln all held the title of land surveyor. In fact, it was Thomas Jefferson who sent Lewis & Clark on their famous expedition of the Louisiana Purchase.
Land Surveyors Continue Making History
Although the days of early America are far behind us, land surveying still plays a major role in our modern society. Today, land surveyors pinpoint where your particular land begins and ends so you won’t accidentally build over someone else’s land. Surveyors are able to set boundaries as well. Many things have changed since the days of Lewis & Clark. Now, we’re able to use highly advanced technology to garner the most accurate readings. If you own land and want to begin developing it, make sure to speak with a land surveyor from Land-Mark Professional Surveying. We offer our services to clients in the Southwest regions of El Paso and New Mexico. When you partake in land surveying, you’re partaking in American history!

The purpose is to make sure that the owner of the plot of land knows what pieces of ground are theirs and where their property ends. Land-Mark Professional Surveying, Inc. can provide assistance with boundary surveys in El Paso. The practice of surveying dates back even before people began building structures. Now, in the modern age, Land-Mark Professional Surveying can help.
History of Surveying
In 2,500 B.C., prehistoric surveyors set Stonehenge’s area with Peg and Rope geometry. Surveys, therefore, date back at least this far. When it comes to boundary surveys specifically, ancient Egyptians used to use simple geometry and a rope structure to conduct this type of survey. The rope structure and the geometric tools would re-establish the boundaries of lands after the Nile River flooded each year. In ancient Rome, land surveyors were professionals. With the developing of more tools, the modern surveying process began. And, in 1620, Gunter’s Chain was first introduced to make it possible for plots of land to be surveyed for both legal purposes as well as for commercial purposes. The long tradition of surveying began so long ago continues to this day.
Boundary Surveys in El Paso
