有关mapinfo的源程序，主要是用于GIS的二次开发。-the source, GIS is used mainly in the secondary development.

应用背景在物力大地测量学中，重力异常的计算，需要测量计算点的重力值和计算测量点的正常重力。计算正常重力时，需要已知计算点大地坐标，即经度、纬度和大地高，如果采用GPS采集数据，那么获得的大地坐标的参考椭球是WGS84。关键技术此程序，采用WGS84参考椭球参数，因此输入数据为WGS84大地坐标，顺序为，纬度、经度、大地高。输入文件为，Input.dat。输出文件为，output.txt。计算结果为，椭球面以上高程为h处的正常重力。如果将大地高设为0，那么计算结果为此点处参考椭球面上的正常重力。

新的等值线编程实现，很好用的的东西阿，不能错过-contours of the new programming, the good thing A, not to be missed

ArcGIS二次开发编程实例。全书分两部分：基础篇和提高篇。基础篇通过 100多个具体的实例详细地讲解了ArcGIS 二次开发过程中涉及到的各个主要的知识点；提高篇则以实际项目开发为例，综合运用基础篇的各个知识点，详细地展示ArcGIS 二次开发的流程、方法和各种开发技巧。-ArcGIS programming examples of secondary development. The whole book in two parts: the basis of papers and articles improve. The basis of more than 100 articles, through specific examples to explain in detail the process of secondary development of the ArcGIS involved in each of the major points of knowledge improve articles while the actual project development as an example, the integrated use of knowledge based on various papers, the detailed display ArcGIS secondary flow development, methods and development techniques.
