How Modern Technology is Revolutionizing Contemporary Land Surveying Methods?


For the longest time, land surveyors resorted to traditional methods for land surveying, be it topographical, construction, or boundary surveying. While these methods accomplished the data collection goal, the entire process was sluggish, resource-intensive, and prone to errors. It was also impossible to use these in adverse weather conditions.

Today, LiDAR, GPS, mobile mapping, and other modern technologies have revolutionized the way surveys are conducted. Surveyors are now able to remotely operate UAVs and access difficult terrains in the most hostile weather conditions. 

In this article, we will talk about how technological disruptions have paved way for efficient and accurate land surveying. But first, we need to understand why surveying should be done.

Why is there a need to conduct a land survey?

Let us put a picture in front of your eyes. Think of a massive canvas, not an entirely blank one though. Imagine the canvas has dents on it, it is disfigured in some areas, and it has unwanted elevations which are disturbing the uniformity of the canvas. Before starting the painting, you will want to survey the canvas and fix these issues, right? It’s the same with land!

Land surveying is the first step in the construction or renovation process. It’s a process where the surveyor uses different equipment to calculate horizontal distances, height, elevation from the surface, and direction of different points on the earth’s surface. 

Here’s why Land Surveying Services are essential for your project:

  • Understanding Topography
  • Determining Plot Size
  • Dividing a Plot of Land
  • Property Upgrades
  • Compliance with City Codes and Planning Standards Better Communication before Construction
  • Encroachments
  • Renovation and Demolition

What are the Different Types of Land Surveys? 

  • Boundary Survey: A boundary survey is used to determine the boundaries of the land that needs to be developed.
  • Construction Survey: Construction surveys are carried out when planning of construction activity and placement of equipment is to be done before the beginning construction process.
  • Topographic Survey: Topographical survey is the process of identifying precise locations of different elements (natural and manmade) on the earth’s surface.
  • Site Planning Survey: It is the combination of the boundary survey and topography survey and is used to make improvements during new construction.
  • Subdivision Survey: A subdivision survey is used to divide the land into smaller sections.
  • ALTA Survey: ALTA survey is a boundary survey method that strictly adheres to a set of standards developed by the American Land Title Association (ALTA) and the National Society of Professional Surveyors (NSPS).

These surveys will help determine the quality, positions of natural and manmade elements, and terrain of the land, and help surveyors take appropriate steps in the process.

The survey process needs to be accurate, otherwise, it will lead to complications in the construction that will follow. For that, surveyors need to use modern, state-of-the-art equipment that will record and deliver precise values. 

What are the Modern Technologies used in the Survey Industry

Today, land surveys are conducted using both traditional and modern technology-aided surveying methods. 

  1. Total Station
  2. GPS
  3. UAVs / Drones
  4. LiDAR
  5. Mobile Mapping System
  • Total Station

A digital instrument that allows surveyors to map the height and distances of different elements in a landmass, be it manmade or natural. 

  • GPS (Global Positioning System)

Latitudinal, longitudinal, height and distance values between two points can be mapped accurately using GPS. Using GPS not only saves time but also saves money as less manpower is required compared to other surveying methods.

  • UAVs (Unmanned Aerial Vehicles)/Drones

Drones equipped with high-resolution cameras and GPS are a great option to get accurate data points while conducting a topographic survey. Drones and other UAVs also allow surveyors to get data points from areas that are difficult for humans to access. 

  • LiDAR (Light Detection and Ranging)

LiDAR uses a near-infrared laser to measure distances on land. It is one of the fastest surveying methods that collects longitudinal, latitudinal, and height values of an area. 

  • Mobile Mapping System

Mobile Mapping System is a modern surveying technique where GPS, GNSS, LiDAR, and other positioning systems. 

The way surveys are carried out has been altered by these technologies. Surveyors are now able to deploy these solutions and collect highly accurate information on the most remote and inaccessible landscapes in a quick and efficient manner.

This information is then drafted in 2D on a map that defines the boundaries. Contour lines are then drawn on a map based on the results of the survey.

Technology Transforming Traditional Land Survey Methods

With the advent of modern technologies, land surveying took on a crucial role in determining the ease of development.

The following are the benefits of these technological advancements:-

  • Precision – Accurate results are presented in a few hours thanks to advanced technology.
  • Speed – Surveyors can cover a large area of land more quickly by using a drone.
  • Scope of Work – With new technologies you can combine topographic surveys, photogrammetry, 3D mapping, and other methods with land surveys.
  • Enhanced Safety – A drone may be able to survey an area that would be challenging and unsafe for a surveyor to access on foot, which can further cut down on time and improve the surveyor’s safety.
  • Improved Decision Making – Data collection is quick and precise, allowing clients to make defensible choices early in the project’s development and maintain momentum.
