Sammen med Augmented Reality vil 3D GIS komme til at fylde rigtig meget i morgendagens GIS løsninger for folket ... Vi vil ikke kalde det GIS da det jo kun er noget for nørder ...

Along with augmented reality we will see GIS being used A LOT - it won't be called GIS but that's also just for nerds ...

3-D and 4-D information, particularly when supported by analysis, processing and integration software can open the door to whole new ways for thinking about everything we see and do.
- Picture a farm producer traveling across a field. In the cabin of the tractor is a complete picture of the farm - below ground - displaying soil moisture content and level of soil N, P, K and S (as well as a few micro-nutrients). Models running in the tractor, based on the information as 'decision-making' where and how much fertiliser to apply. This sounds like a typical precision farming application, but it's not. Soil moisture by depth significantly impacts rate and amount of infiltration and soil moisture by depth is slope and aspect dependent - 3D.
- Imagine a lidar pount cloud. It consists of about 100 million data points. Rather than displaying all of these points, it is decided to display only those for areas previously processed in 3D through GIS analysis. That is, a 3D polygon has been determined. Picture a bomb blast or an atmospheric release of gases within a 3D space and you want to know what objects (determined by point cloud) will be impacted. Perhaps modeling the wind flow through these spaces.
- Think of a GNSS application with a GPS receiver. Your job is to representively sample a 3D space. How do you pre-program a GPS to take samples (locations - measurements) in a 3D space?
- How would you create a 3D visualisation of a 'what-if' scenario? How would you display a series of remotely sensed images witin a 3D space? We have all seen pictures rotated in 2D space - flipped back and forth. Is this where levels of visualising uncertainty come in, where fuzzy boundaries begin to take shape?
