Todayâ€™s times, there are more visitors entering a city exceeding the number of
its residents. In such situations we are left with less resources and more
users. A shortage at all levels right from basic infrastructure i.e.
roads, water, electricity to space to live and work. Although we need human
resource to support a growing city but it comes with same amount of
responsibilities and resources needed to provide them with at least basic
necessities within a limited space and time. Such situations arise due to lack
of proper planning and allocation which is only possible with the use of
advanced technology and modern engineering practices. Where we need to begin
with analyzing and visualizing a cityâ€™s future needs and designing it
explore photogrammetry and GIS Software.
They help us craft, evaluate and visualize a 3D City model which can sustain
the future needs. These models can further be used to determine solutions
needed to plan a competent structure that works fine for day to day
administration and also addresses emergency situations efficiently. Firstly, 3D
Vectors having ground features corresponding to global coordinates are acquired
with Photogrammetric technologies and developed by utilizing GIS Tools to add
attribute information and display graphical models. In the process, digital
photogrammetric workstations (DPWs) process aerial data and GIS workstations
model the data produced as 2D Maps, Static 3D and 3D Animation.
CURRENT URBAN ENVIRONMENT
to population burst, currently certain cities are experiencing a havoc in terms
of managing and serving its citizens. The increasing stress on resources every
moment is creating a situation which cannot let these cities and towns survive
for long. Hence, the only requirement is an improved and in fact properly
an effective system for distribution of resources. In India, the problems are
self-sustaining with the ever increasing need of proper accommodation,
conveyance, waste disposal, electricity and water requirements. Environmental
crisis in the cities jam-packed with infinite vehicles is again an issue that
needs a solution as soon as possible. Here the problem majorly lies with the
slums and its crammed residents, who get into the cities for industrial
development, creating posh infrastructure and locations yet they them selves
donâ€™t get a proper place to reside and to add to it all the resources needed
for development comes from the forests and natural sources which are limited or
merely exist as compared to their previous availability.
The latest geo-technologies lets us
understand a situation with forecasts that helps in planning a city that could
appropriately use resources and provides a suitable environment to accommodate
the required number of residents. Using modern computer technology and
simulators, city planners try to visualize and plan for a city, keeping in mind
its limitations and complexity thereby making it proficient for future use.
Here the planning is done using 3D Models which is time-efficient and takes
less effort in creating a feasible environment. They replicate the real world
situations so that the problems that may arise are addressed beforehand thereby
giving them a base to take proper decisions and implement better ideas quickly.
Technology help make 3D Digital Elevation,
digital terrain models and planimetric feature extraction. The collected
imagery is geo-referenced using aerial surveys with ground control points
(GCP). It represents various features of infrastructure and other geographic features
to assist better planning.
Results obtained from the Geodatabase are used to evaluate and
analyze information, design structures and help authorities plan accordingly. A
major advantage of 3D City Planning Using GIS & Photogrammetry Techniques
is that we can deal with a situation much before it arises or even exists, keep
features and utilities at place according to tomorrowâ€™s requirements and
allocate resources as per the need. This can be done to improve the existing
infrastructure or to plan a subsequently new one on a fallow land. The software
applications help visualize data taken by the GIS & Photogrammetry
Techniques and use it in a relevant context to generate insights and utilize
them for an efficient planning.
