Different kinds of maps are being created today for various purposes. For example, a city can hire an illustrator to create a map illustration that will capture architectural details in an artistic manner. The illustrated map can be displayed at the lobby as a perfect conversational piece. There are also road maps for navigational purposes and 3D maps for certain projects.
During one hot Tuesday, people saw a helicopter hovering over rooftops in the city of Bangalore. Its mission was to map the solar potential of rooftops so that people can take advantage of the abundant sunlight. The data gathered which will be placed in public domain has the potential to help people in reducing their electric bills. The solar energy that will be generated can be consumed with the excess sold to make some money.
The helicopter took off from Jakkur Aerodrome and lingered particularly on the dense concrete stretches. The team aboard the helicopter including The Hindu which was given exclusive access took down the most important notes.
The helicopter had a camera onboard that emits laser pulses. It was able to capture reflections from the ground that will be used in creating 3D maps. The raw data will be delivered to the Defense Ministry for vetting before it will be used in the process of shadow analysis and creation of a model city map.
The web-based rooftop photovoltaic tool uses LIDAR (Light Detection and Ranging) system for the project that is being executed by the Center for Study of Science, Technology and Policy (CSSEP) for Bangalore Electrical Supply System. The purpose of the project is to create a map of rooftop solar prospects. In 2 ½ weeks, about 990-oddsquare kilometers have been covered and includes dense urban sprawls and industrial zones. The outcome will be a game-changer for Bescom as well as its consumers.
Technology is now an indispensable tool in the creation of maps but while commercial web mapping is quite popular right now, map illustration is still widely used for print media. A map of a city, school campus, business center or town is crafted from a favorable vantage point which is from above where you get an oblique view.
