A Closer Look into 3D Mapping and 3D Modelling
05:45
Some people might be quick to say that both 3D mapping and 3D modeling are the same, but they are not. While it is true that there is some form of overlap when it comes to the solutions and technology between the two, they certainly do have considerable differences especially when it comes to how they are executed as well as in the resulting outcome.
It is safe to say that there is no scientific difference between the two. However, when one views a map, he will see that it is flat, which makes it two-dimensional. Through the use of modeling technology, it is easier to get the results converted from a flat map to one that is going to be triangulated where the viewer gets to see facades.
What is 3D mapping?
Most of the drone companies that are involved in photogrammetry refer to the flat map as 3D mapping. This is because the creation of a map that is accurate through the use of aerial photographs provides a result that definitely does not look like the usual maps of lines and dots that most people have been used to seeing in the past.
The resulting map is an image of a terrain, a precise one. This includes the natural components and the buildings that make up the terrain. It will give the viewer a sense of depth and size. It is usually combined with other details such as industry-specific information or thermograph data to make it an actionable tool.
Orthomosaics and photogrammetry are used to create 3D maps. This is what results in maps that are accurate and are easy to use for a number of applications such as urban planning, surveying, construction, as well as land management.
What is 3D modeling?
The required equipment for this particular process is pretty much the same. But the drone operators that are aiming to create a 3D model will have to take oblique shots to make sure that there will be images of facades. A modeling software is then used to create realistic fly-through videos or 3D models.
3D modeling is useful or a number of purposes. For commercial purposes, it can be used in real estate or it can also be used to come up with maps that are more creative. Today, more and more people are opting to go beyond 3D mapping and want to take advantage of 3D modeling. There is more interest in 3D modeling thanks to the fact that it provides a detailed and precise look into the elements that make up the map. What used to be ubiquitous maps that are flat and strictly in 2D can now be transformed in a way that will allow users to have the experience of being physically there and actually walking the streets as they explore around. They can even be made to be more interactive.
