H4GEO Service

Topographic LiDAR is a remote sensing technology that uses a laser scanner to quickly obtain fine and precise

It is used to create high-resolution digital elevation models (DEMs) of a land, which can be used for a variety of applications, such as mapping, land-use planning, and real estate development. The technology can also be used to create detailed 3D models of a land, which can be used for BIM modeling.

Compared to other remote sensing technologies, such as photogrammetry or radar, Topographic Lidar provides higher accuracy in dense forest canopies, urban areas, and other challenging environments. The data collected through Topographic Lidar can also be used to extract information about vegetation, land cover, and other surface features.

This service includes the following steps:

  • Acquisition of lidar data by drone
  • Data processing
  • Digital mapping

May be suitable for the following areas:





Why is Topographic LiDAR Useful in Construction and Architecture?

Topographic LiDAR (Light Detection and Ranging) is an advanced technology that has transformed the fields of construction and architecture. Additionally, this technique allows for the creation of highly accurate topographic maps and digital models of a terrain.

First and foremost, Topographic LiDAR is employed in the construction, architecture, and planning industries as it enables the creation of extremely precise Digital Terrain Models (DTMs).

What are the advantages of Topographic LiDAR?

Better Planning and Project Management

These digital terrain models serve as an essential foundation for the planning and design of construction and architectural projects. They provide a detailed visualization of the terrain, including elevation variations, contour lines, and relief details. This information is crucial for designing buildings and infrastructure that seamlessly integrate with the surrounding environment.

Enhanced Vegetation Analysis

Topographic LiDAR can penetrate tree canopies and generate accurate data on the height, density, and distribution of vegetation. This capability allows for improved planning of landscaping projects and a better assessment of the environmental impact of construction projects.

Furthermore, Topographic LiDAR facilitates flood risk analysis and drainage issues by mapping watersheds and watercourses. This method helps identify flood-prone areas and design effective drainage systems to protect buildings and infrastructure.

Improved Inspection for Architectural Projects

Topographic LiDAR is essential for inspecting and documenting existing buildings. It enables the creation of detailed 3D point clouds of both the interior and exterior of structures, thereby facilitating renovation, restoration, and preservation of architectural heritage.

Why Choose Topographic LiDAR for Your Projects?

Topographic LiDAR is an indispensable tool in construction and architecture because it:

  • Provides accurate topographic data
  • Analyzes vegetation
  • Assesses flood risks
  • Documents existing buildings

It is a key element to aid in the design, planning, and preservation of built spaces, contributing to the realization of sustainable projects that are well-integrated into their environment.
