GEOGRAPHIC INFORMATION SYSTEMS

SEMINAR ON GEOGRAPHIC INFORMATION SYSTEMS : The idea of using layers is an old man. Layers of information traditional maps have been used for practical purposes a long period. But computers is the application of this The concept of a lot of practice. GIS has been a positive change in the era of hand cartography when the cards had to be carefully done by hand, even small necessary changes in the new map. The first version known as computer cartography and GIS line work is simple to represent the characteristics of the land at the top other to determine the manner and causes of spatial phenomenon. The characteristics of GIS is far from simple motivation Computer cartography. At the simplest level, GIS can be responsible for the high-tech map. It is not only can be produced paper maps much faster and more efficiently storing data in an easily accessible digital format enables complex analysis and modeling have not possible. Reach of GIS expands into all disciplines and been used for varied problems that the priority sensitive species habitat to determining optimal real estate locations for new businesses. The key word of this technology is geography, which generally means that spatial data is, in other words, data that is somehow reference to the places on earth. There is also often
information is called attribute data. The characteristics are defined in general terms information, which may be linked to spatial data. example of this would be schools. The location of schools spatial data. Additional data such as name of school, level the education taught, school capacity would attribute data. It is the partnership between these two data that allows GIS as a tool for solving problems effectively. GIS operates on many levels. At the simplest level, GIS used as computer cartography, ie mapping. The real power in GIS and statistical methods to analyze spatial attribute and spatial information. The final result The analysis can be derived information, interpolated information.
