Encapsulation Application Research of ArcSDE Access Interface in .Net Environment
Abstract
The GIS and Digital Roadbed System of the Qinghai-Tibet Railroad is developed in the .Net environment and designed to store and to manage the information along the Qinghai-Tibet railroad which is 1118km long and is constructed in the regions more than 4000m high Spatial data Management plays a very important role in this GIS, and ArcSDE was selected to implement the management of mass spatial data. How to connect ArcSDE and exchange vector and raster spatial data in this system is a key technique. There are three approaches, which are recommended officially, can be used for client to connect ArcSDE, but none of them can meet the needs of spatial information storage and management in the GIS and Digital Roadbed System of the Qinghai-Tibet Railroad. This paper explained a solution of encapsulating the ArcSDE Client API for C programmers into the form of Net managed code with C++ programming language The final program not only provides a solution to resolve the problem of spatial data management_but also bring forward a flexible interface which followed the principle of OOP.
