The Third Dimension - A third factor that gives the realistic view (3d GIS)

If we turn back and look at the path that has been traversed by the geospatial technology, we could see the journey of amazing evolution of GIS technology starting from cartography and towards improvement and at each stage of its evolution this technology has been getting wide acceptance from the users around the world. The extrusion of GIS technology from paper maps to real time digital maps with the advent in computer and internet technology has given rise to a tempt to become aware about the location, time and cause – ‘where, when and how’. The ability of the geospatial technology to represent the world and its phenomenon in three dimension has brought about a revolution in this industry that for the professionals in the fields of architecture, production, planning and decision making belonging to various domains can now mould and analyze a conceptual design in their ideas by defining all the procedural rules and policies that abides by the real world’s and arrive at a conclusion that would best fit during the fare implementation.

For urban planning the 3D GIS can be best used to create a 3D landscape involving all the aspects like the in and surrounding environment, road and utility networks, population density, traffic data etc. that give a realistic view on how the scenarios will be like when the ideas are transformed into real. For the building construction and restructuring segment, a 3D GIS can be used to build a conceptual design and identify the pros and cons like whether the infrastructure blocks any kind of view, is there any violation in its measurements regarding the height and zoning, does the glare caused by the reflection from building affects any around it. Likewise, many analysis and manipulations can be done using the 3D GIS which gives away many speculations and thus the project becomes very cost effective.

The 3D GIS has proved its ability in depicting various crime incidents incorporating all the evidences and speculations and all represented in a 3D environment which facilitates the crime investigators to manipulate scenarios as if it would have happened or has happened. Thus GIS has given way to the crime investigation in a 3D conceptual design to study the incidents and arrive at a conclusion as if like investigating in the real world.

The GIS technology is for sure evolving towards greater improvements for aiding the decision makers to design the future and in depicting the world and its phenomena three dimensionally.
