3D Mapping: An overview

Cartography’s 3D mapping is another wonder of modern technology. Although we are familiar with 2D maps and 3D vision, it is not difficult to imagine how a 3D map might look like? Take advantage of 3D mapping to zoom in close to your location without being hindered by Earth’s curvature.

Profiling objects in three dimensions to map them in real life is called 3D mapping. 3D profiling can be done in several ways, including the use of stereo cameras. Measurement of depth can also be done from the point of focus. By using active 3D imaging techniques or by using plenoptic methods, you can also create a 3D effect.

Three-dimensional mapping has an advantage over two-dimensional mapping

Three-dimensional mapping offers the latest technical methods for visualizing and gathering information, which is one of the best benefits. A 3D map of the object or area under study facilitates knowledge visualisation and science mapping.

Local authorities and planners can use a 3D map to get a realistic view of the location. Construction companies use 3D maps as much as blueprints. A 3D map makes it easy to visualize floor plans and identify potential obstacles during construction.

With the aid of a 3D map, you are able to experiment with many visual effects virtually before the final output. With its ability to determine aircraft positions and make events special through projection mapping, 3D mapping is transforming the world.

Creating a 3D map

Many people refer to 3D mapping as “Spatial Augmented Reality.” It is also known as “Projection Mapping” or “Video Mapping.”

In projection mapping, surfaces can be transformed into dynamic visual displays using a technique. While there are many ways to achieve the same result, combining 2D or 3D data with computer animations can highlight the desirable features and diminish the less important ones.

Maps in 3D in GIS

If you collect data for GIS analysis, you can enhance depth by using a Z value (other than x and y). Three-dimensional GIS plays a critical role in city planning, BIM, coastal modeling, and wind farm assessment.

Creating 3D scenes of a location using 3D mapping and cartography is an important way to study the development of a high-rise building, its interior and exterior, and the effects of a disaster. With ArcGIS, you can easily make a 3D map. “ArcGIS scene viewer” is a feature of ArcGIS. ArcGIS Pro is another desktop application from ArcGIS. It has many extensive 3D inbuilt capabilities because it is a 64-bit application. A 2D view along with a 3D scene can be viewed at the same time, side by side.

A 3D map provides precise information like the location of a fire and enables quick disaster response.

As well as creating maps that can be used in resource management and planning, AutoCAD Map 3D software can also be used for this purpose.You can enhance the quality and productivity of your project by integrating GIS data with CAD tools and intelligent models.

Microsoft Excel allows you to create 3D maps as well. Your data must be entered into a worksheet (with X and Y coordinates), then selected. Do not ignore the column headers. To learn more about 3D Maps, click on insert, followed by 3D Maps.

There are numerous applications for 3D mapping in a variety of fields, including science, entertainment, and advertising. Why should the Earth be represented in 2D when it is not flat? Adding the ‘Z’ coordinate will make your projects a reality.
