Advancements in remote sensing technology, such as LiDAR, help develop the most accurate 3D digital terrain models (DTM). These 3D visualization models are helping engineers and other industries to get better terrain analysis.

TL; DR: Importance of 3D digital terrain model studies in various industries

• Digital terrain models help civil engineers in urban planning surveys
• Using LiDAR technology, the developed 3D DTM helps to identify high mineral zones precisely.
• DTM integrated with GIS Mapping helps to identify the flood risk areas precisely.

Previously, the digital terrain models were used to study the hydrology, geography, and oceanography. But the latest 3D digital terrain models are helping civil engineers in various construction projects, offering accurate terrain analysis. By using LiDAR technology, digital terrain models are created and are helpful in different operations such as urban planning, disaster management, and more. Let’s discuss in detail.

Surveying

Surveying the Earth's geospatial landscapes is crucial before planning any construction on the Earth's land. But the 2D mapping doesn’t provide enough information, so the latest technology is used in studying the bare 3D earth landscape. They give the essential data about the flood risk, slope calculations, and soil volume estimations, which help to make precise decisions on construction planning.

Mining

The risk in the mining industry is huge for employees working on-site. So, the demand for safe and sustainable mining practices is rising. Now, with the latest advances in geospatial terrain analysis and a clear understanding of 3D digital terrain models, the potential risks and fatal accidents are lowering in the mining industry.

The LIDAR technology helps to accurately identify the high mineral-rich zones without the need for extensive onsite surveys. The 3D digital terrain models serve as a guide on how to safely approach risk-prone mining areas without causing any ecological disruptions.

Flood risk assessment

One of the serious hydro-meteorological hazards is floods, taking away millions of people's lives every year. Deforestation, rapid urbanization, and global warming are the reasons for frequent floods. To prevent the effects of floods and to save more lives, the GIS mapping Georgia technology studies are helping a lot. These remote sensing technology gathers information about the earth’s surface using satellites, aerial sensors, and LiDAR drone technologies. In addition, integrating the digital terrain model with GIS satellite imagery helps in flood detection, such as identifying low-lying flood-prone zones.
