How Land Surveying Has Evolved Over Time
Land surveying has been an integral part of human civilization since ancient times. It has been used to measure and map land, and to divide it into parcels for ownership. Over the centuries, land surveying has evolved from a simple process of measuring distances and angles to a complex science that uses sophisticated technology to accurately measure and map land.
In ancient times, land surveying was done using simple tools such as a measuring rod, a compass, and a plumb line. These tools were used to measure distances and angles, and to determine the boundaries of a parcel of land. This process was known as “chain surveying” and was used to create maps of the land.
In the 18th century, the development of the theodolite allowed surveyors to measure angles more accurately. This instrument was used to measure angles in both the horizontal and vertical planes, and it allowed surveyors to create more accurate maps.
In the 19th century, the development of the transit and the plane table allowed surveyors to measure distances more accurately. The transit was used to measure angles in the horizontal plane, while the plane table was used to measure angles in the vertical plane. This allowed surveyors to create more accurate maps of the land.
In the 20th century, the development of electronic distance measuring (EDM) instruments allowed surveyors to measure distances more accurately than ever before. EDM instruments use lasers or microwaves to measure distances, and they are accurate to within a few centimeters.
Today, land surveying is done using a combination of traditional methods and modern technology. Surveyors use GPS receivers, total stations, and other sophisticated instruments to measure and map land. They also use computers to store and analyze data, and to create detailed maps of the land.
Land surveying has come a long way since ancient times. It has evolved from a simple process of measuring distances and angles to a complex science that uses sophisticated technology to accurately measure and map land.

The most common type of land survey is a boundary survey. This survey is used to determine the exact boundaries of a property, including the location of any existing structures, fences, or other features. The surveyor will use a variety of methods, such as aerial photography, GPS, and ground measurements, to accurately map the boundaries of the property.
A topographic survey is used to create a detailed map of the land, including its elevation, contours, and other features. This type of survey is often used to plan construction projects, as it provides a detailed view of the land that can be used to plan the project.
A construction survey is used to ensure that a construction project is built according to the plans. The surveyor will measure the location of the project and compare it to the plans to ensure that it is built correctly.
A mortgage survey is used to verify the boundaries of a property for a mortgage lender. The surveyor will measure the boundaries of the property and compare them to the deed to ensure that the property is accurately described in the deed.
A subdivision survey is used to divide a large parcel of land into smaller parcels. The surveyor will measure the boundaries of the parcels and create a map that can be used to divide the land.
Finally, an ALTA survey is used to provide detailed information about a property for a potential buyer. The surveyor will measure the boundaries of the property and create a detailed map that includes information about the location of any existing structures, fences, or other features.
Each of these types of land surveys serves a different purpose, and it is important to understand which type of survey is needed for a particular project. A qualified surveyor can provide the necessary information and ensure that the project is completed accurately and efficiently.
How to Prepare for a Land Survey
