In Today’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 city’s future needs and designing it accordingly.
Let’s 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
Due 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 planned infrastructure and 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 don’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.
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 tomorrow’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.
