The Research And Implementation Of WebGis Based On .NET And MapObjects

I intend to resolve automatic distribution of geography data, superposing geography map layers under the control of remote clients and to keep the geography map layers property data in a secure application circumstance. Therefore, I brought forward and implement the WEBGIS based on DOTNET and MAPOBJECTS components.After analyzing what kinds of technologies we often use to implement WEBGIS, I think I can produce the WEBGIS by separating the map elements and property data. At the same time, I applied the effective data access ability and the authentication method of ASP.NET to guarantee the efficiency and security of data access in this system. Afterwards, I designed and implemented an algorithm of map superposing. By using the algorithm, I managed to superpose map layers under the control of remote clients. That will realize the integrated application of data belonging to the system and the customer themselves.Furthermore, I would introduce the smart client and WEB services to show the excellence (user interface and security) when we implement WEBGIS with the infrastructure of smart client and WEB services.
