A multidimensional web-application for dynamic quering into geographical information system
Κουγιουμτζής, Δημήτριος Α.
Before the evolution of computer science for the management of geographic data we made use of maps. The evolution of computer science although has allowed us to create digital maps. The management of geographic data requires the use of geographic databases for execution of spatial query. In this master thesis we present the development of an application which offers the ability to the user to find a specific point of interest in a specific area. The first way of doing this is by giving the ability to the user to draw a polygon on a Google map and to select a point of interest he wants to find in that area. The database then returns the results of the points of interest that the polygon contains if any. The second way is by just drawing a line (path) on the map and selecting a point of interest. The database then returns the points of interest that are close to that line.
