Shanghai to open Remote sensing map site to see more clearly than Google

Light mouse, not only can real-time view the greening of the community and surrounding traffic site distribution, even the structure of the roof tank can be seen clearly ... At the 2009 International Conference on Urban Remote Sensing held yesterday, Sun Jianzhong, director of the Information Technology Department of Shanghai Urban Development Information Research Center, said that in the construction of the Shanghai Spatial Information Basic data platform, the city will open the relevant "Remote sensing map" website to provide guide for the citizens ' travel and purchase.

Coincidentally, yesterday, Shanghai three-dimensional geological structure model debut. For those who are preparing to buy a house, there is also a new geological reference index.

Some developers often use inaccurate descriptions of real estate advertisements, such as "a few minutes away from the subway XX station" to mislead homebuyers, but not long, such tricks can be easily detected. At the 2009 International Conference on Urban Remote Sensing, held yesterday, Sun Jianzhong revealed that in the construction of the Shanghai Space Basic data platform, the city will open the relevant "Remote sensing map" website, and now Shanghai has a large number of remote sensing map data obtained by aviation and satellite remote sensing, and has built the spatial information base data platform.

Yesterday, the reporter used "Google Maps" search the vicinity of Waitan in Shanghai, the sparkling Pujiang water, wide roads and high-rise buildings are clearly visible, but the road can only see the vehicles, pedestrians, leaves and other things will be difficult to without let. Future use of the Shanghai version of "Google Map" can be seen more clearly. "The resolution of aerial remote sensing can reach 0.25 meters, and pedestrians and zebra crossings on the road are fully visible." Sun Jianzhong said that the resolution of the "Remote Sensing map" in Shanghai was higher than that of "Google Maps".

Since the opening of the spatial information basic data platform in 2002, the platform has been applied to urban greening maintenance, traffic adjustment and so on, based on the data platform, Shanghai plans to open the application website for the citizens. By then, buyers can be online netizens, the "home" of commercial housing to find out. Whether there are large green areas around the real estate, traffic conditions, there are no schools, hospitals, and even the direction of the purchase of housing information can be "panoramic view." After the site is expected to open, there will be hundreds of indicators for the public to select real-time viewing.

　　Underground: stratigraphic structure at a glance

If the "Remote sensing map" mainly look at buildings on the ground, then "underground three-dimensional map" can let you have a more in-depth understanding of the environment around your home, for those who are preparing to buy a house, but also a new geological reference indicators.

Yesterday, the reporter saw the first three-dimensional geological structure model in Shanghai on the ring screen of the Shanghai Institute of Geological Survey. Different shades of color on the model represent the various layers of the ground beneath the region. Display staff at random on the model to draw a line as a "tunnel", click on the "tunnel", "tunnel" in the geological structure is also a three-dimensional display, reporters as if by the drilling truck, carried out a "tunnel trip." "These three-dimensional data are all derived from the data integration of Shanghai geology for more than 50 years." "Shanghai Geological Research Institute deputy chief Engineer founder said, the relevant strata of information from the geological exploration, urban construction and other departments, the public has now been able to log into the Shanghai Urban Geological Information Network, to understand the secrets of the land under foot."
