What is 3D Mapping

Another marvel of modern technology, 3D mapping is a new machine vision technology in the field of cartography. While we are already acquainted with 2D maps and 3D vision, it is not difficult to imagine what a 3D map would look like. Don’t let the curvature of the Earth obscure your view; instead, use 3D mapping to zoom in close to your location.

3D mapping is the process of profiling objects in three dimensions in order to map them in the real world. There are several methods for 3D profiling an area or object, such as using a stereo camera pair. Another method is to calculate the depth of an object or feature from the point of focus. You can also create a 3D effect by using plenoptic methods to detect the light field or active 3D imaging techniques.

Advantage of 3D mapping over 2D technology

One of the most significant advantages of 3D mapping is that it provides the most advanced technical methods for visualisation and information gathering. When a 3D map of the object or area under study is available, knowledge visualisation and science mapping become easier.

A 3D map provides a realistic view of a location that local governments and planners can use. A 3D map is just as useful as a blueprint in the construction industry. It is very simple to visualise floor plans on a 3D map and identify potential construction obstacles.

When you have a 3D map in front of you, you enter a world of limitless imagination in which you can virtually experiment with many visual effects before the final output. From determining aircraft position to making your event unique with projection mapping, 3D mapping is acting as a magical eye.

3D map preparation

“Projection Mapping” or “Video Mapping” are other terms for 3D mapping. Many people refer to 3D mapping as “Spatial Augmented Reality.”

A technique is used for projection mapping that can convert any surface into a dynamic visual display. Though there are numerous ways to achieve the same effect, combining 2D or 3D data with some computer animations can highlight the necessary features while minimising non-essentials.

3D mapping in GIS

When collecting data for GIS analysis, a Z value (other than x and y) provides greater depth. Some of the applications of 3D GIS include city planning, building information modelling (BIM), coastal modelling, and wind farm assessment.

3D mapping and cartography are important tools for creating 3D scenes of a location that can be used for many studies such as high rise development, building interior and exterior, and disaster effects. If you want to make a 3D map with ArcGIS, you can do so in a few simple steps. ArcGIS includes a feature called “ArcGIS scene viewer.”

ArcGIS Pro, another desktop application from ArcGIS, is a desktop application. Because it is a 64-bit application, it has a wide range of 3D capabilities. It allows you to work with both a 2D view and 3D scenes at the same time, side by side.

3D mapping provides detailed information such as fire coordinates and aids in disaster response.

You can also use AutoCAD Map 3D software to create maps that can be used for resource management and planning. You can improve the quality and productivity of your project by integrating GIS data with CAD tools and intelligent models.

Few of us are aware that we can also create 3D maps in Microsoft Excel. Enter your data into a worksheet (with X and Y coordinates), then select it. Column headers should not be overlooked during this step. Now, click Insert, then 3D Maps, and then open 3D Maps to learn more.

3D mapping has numerous applications ranging from science to entertainment to advertising. Why represent the Earth in 2D when it is not flat? Add the ‘Z’ coordinate and watch your projects come to life.
