High Resolution Terrain Mapping

Digital terrain mapping (DTM) is a 3D modelling technique. This data can then be converted into high-resolution models and used to visualise a landscape or surrounding area in relation to the object being surveyed. Because DTM allows users to get an accurate representation of the scale of the surrounding environment, it can be helpful for planning projects that involve moving large amounts of earth.

In some cases, DTM models can be used to show how a building will look after construction is complete. For example, they can be used to create visualisations showing the surrounding areas of buildings that have been proposed and are currently under construction.

Digital terrain maps that have been created using 3D mapping provide users with accurate surface information on objects and structures. This means that they can be used for planning purposes and visualisations and monitoring changes over time.

In this sense, DTM models have been used to monitor urban growth in areas such as London and other major cities.

3D visualisations can be used in a variety of ways. For instance, they might be used to assess the impact of new buildings or structures on the surrounding environment, which helps engineers to make changes that reduce any potential damage.

3D modelling can also be used to create visualisations that show how proposed structures might look once they are built. They can also be used as part of public consultations as they allow people to see what the results would look like in the real world, rather than as „flat” maps on a page.

This is particularly useful for planning purposes because it allows engineers to make changes to their designs before committing to building them, which reduces time and costs.

A 3D modelling system also allows engineers to create more accurate images and visualisations that can be used for risk assessment purposes.

Laser scanning is an excellent choice for creating accurate 3D scans which provide detailed information about how different parts of a structure, such as a building or other structures, fit together.

Maps and plans are produced to scale, designed to show the details of the environment accurately. Accuracy is vital as these plans may be used to calculate flood risks, resolve boundary disputes, and many other uses.

Topographical surveys are commonly used for planning the construction of roads, railways, pipelines, etc. and can help inform the placement of buildings within a construction area.

Topo maps are created by a topographer taking measurements of the land, including all physical features, and producing a map to the specification required. Contour lines showing changes in ground elevations concerning distance or direction will be included.
