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.
