地理信息系统－组件开发篇所有例程。书中对各章的实例都进行了编码，读者可根据编码在光盘中找到对应的实例代码。要运行这些应用程序，必须先安装MapObjects与MapX两个组件，而无须其他软件。- Geographic information system- module development all examples
regulation. In the book all carried on the code to each chapter of
example, the reader has been possible to act according to codes found
corresponding in the compact disc the example code. Must move these
application procedures, must first install MapObjects and the MapX two
modules, but does not need other software.
