Top 4 Surveying Systems Used in Creating Top-Class Digital Terrain Models

A top-notch Digital Terrain Model (DTM) requires accurate data and sophisticated survey systems. A DTM serves as a 3D representation of the earth's surface. It is used in construction, mapping, flood assessments and other projects. Enlisting the survey tools ensures accuracy and trustworthiness. Below are four leading survey systems in fabricating terrain models. 


Accurate Construction Surveys

Accurate construction surveys play a role in ensuring a successful plan and execution of construction projects. In construction surveys, using tools like stations and GPS receivers to measure distances and angles effectively is common.

This data is processed into a DTM (Digital Terrain Model) to ensure the construction work alignswith the intended design seamlessly.These survey tools play a role in preventing mistakes or the need for additional work during the construction process.

Drone Surveying

Drone surveying is transforming the surveying industry. It offers cost-efficient solutions for capturing landscapes using advanced cameras and LiDar sensors to create intricate three dimensional terrain models.

Drone surveying service and technology is introduced to create DTMs. They enable surveyors to reach dangerous locations without relying on time-intensive ground surveys. Aerial data collected by drones is transformed into a DTM using software based on photogrammetry techniques to generate DTMs.

As-Built Surveying

These surveys depict the positioning of buildings, critical utilities, and other elements that are part of the design plan.In-built surveys are carried out using laser scanners or total stations to gather precise data for comparison with the original blueprints. The information is used to revise the DTM to represent the conditions post-construction. This procedure is crucial for adhering to regulations and planning for maintenance and alterations.

Planimetric Surveying

Planimetric surveys deal with measuring the aspects of the terrain. Unlike topographic surveys, which capture horizontal and vertical data, this survey focuses on features like buildings, roads, and other structures.

The Planimetric survey method is useful for generating 2D maps or DTMs that emphasize the surface-level characteristics of an area. Total stations and GPS devices are employed to record information about the layout of a location. Planimetric surveys play a role in development and infrastructure planning. They offer detailed depictions of the land surface without including unnecessary elevation details.

Creating a top-class DTM requires accurate data from reliable surveying systems. Professionals use the right surveying tools to create DTMs that serve as the foundation for successful projects.
