| Abstract: | Until now,any GIS software can not process the data of different GIS data sources and other geographic spatial data with format different from its own.In order to use such data,we usually transform the format of the data.A research reported that, in the developed countries,the money used to transform the data format is up to 30 percents of those of data building. A method called "the Back Door" was used to perform the directly reading of nonstandard geographic spatial data with the API and data structure provided by GIS itself.The technique was xuccessfully applied to the PEIOS (Pearl River Estuary Integrated Observing System). |
