降低SRTM3数据点密度
应用背景从SRTM3网站上下载下来的数据，点密度太大，给使用带来不便，程序目的是降低点密度，使其分辨率降低，通过相邻点删除的方式，使其分辨率降低，但仍然保持原来点方阵的格式，例如，原来是n×n，即n行n列，降低密度后，变为原来的一半。n/2*n/2，即n/2行，n/2列。如果n为偶数，则n/2=int（n/2）+1关键技术
程序分两个 separate_jshu.f 和 separate_oushu.f 。输入文件分别为 Input_jshu.dat 和 Input.dat. 即，当原文件 n×n中n为奇数时，使用前一个程序，新生成的文件为 jishu.dat. 新生成行列为 n/2=int（n/2）+1。当原件n×n 中 n 为偶数时，使用后一个文件，新生成文件为 oushu.dat 新生成行列为 n/2.

MoNetBroker是对ESRI MapObjects开发包产品的扩展，它以OCX控件和类型库的方式提供给那些熟悉MapObjects的开发人员，帮助他们利用MapObjects中的数据图层，方便地实现几何网络的连通性分析、非连通分析、两点路径分析、多点路由分析等强大的功能。MoNetBroker可以紧密并方便地与MapObjects相结合，实现高效的网络连通性分析和路径分析等功能。并且具有结点转向和线路单行控制、末梢点线选择等丰富的处理能力。-MoNetBroker of ESRI MapObjects Development Kit product expansion, which was OCX controls and type library available to those familiar with MapObjects developers, to help them use MapObjects the data layer, to facilitate the realization of the geometric network connectivity analysis, non-connected, 2:00 path analysis, multiple points of the road analysis by the powerful functions. MoNetBroker can work closely to facilitate the integration and MapObjects to achieve effective network connectivity analysis and pathway analysis capabilities. And with node shift and line single control point line peripheral rich choice of the handling capacity.
