静态综合实验

123.topo第一次实验

此资源是HCIA-R&S学习完成后的综合测试实验。可参考博客：https://blog.csdn.net/qq_45668124/article/details/105671086

ETOPO1 is a 1 arc-minute global relief model of Earth's surface that integrates land topography and ocean bathymetry. It was built from numerous global and regional data sets, and is available in "Ice Surface" (top of Antarctic and Greenland ice sheets) and "Bedrock" (base of the ice sheets) versions.

完整DEMO。纯前端代码，后台采用模拟数据。稍加修改即可用于自己的项目中。

This readme file contains information on the ETOPO1 binary grid formats. ETOPO1 comes in two different binary formats: 2-byte/16-bit integer (i2) and 4-byte/32-bit float (f4); float refers to the file format, not the elevation values in the grids, which have been rounded to whole integers for all versions. Each zip file contains the binary grid and an associated header file that describes the grid format. ESRI ArcGIS users should use the f4 version and convert using 'Float to Raster'. An example 4-byte float header file, of the ETOPO1 Ice Surface grid-registered grid (etopo1_ice_g_f4) is: ncols 21601 nrows 10801 xllcenter -180.00 yllcenter -90.00 cellsize 0.01666666667 NODATA_value -99999 byteorder LSBFIRST NUMBERTYPE 4_BYTE_FLOAT MIN_VALUE -10898.0 MAX_VALUE 8271.0 An example 2-byte integer header file, of the ETOPO1 Bedrock cell-registered grid (etopo1_bed_c_i2) is: NCOLS 21600 NROWS 10800 XLLCORNER -180.000000 YLLCORNER -90.000000 CELLSIZE 0.01666666667 NODATA_VALUE -32768 BYTEORDER LSBFIRST NUMBERTYPE 2_BYTE_INTEGER ZUNITS METERS MIN_VALUE -10803 MAX_VALUE 8333 ETOPO1 1 Arc-Minute Global Relief Model

在GIS领域，拓扑（topology）算法是一个很重要的算法。它把平面上的线段、折线，自动连接成网络，进而构成封闭的区域。 从而形成面和面之间、面和线之间、线和结点之间等各种空间关系。 通过这个算法，可以把给定区域内的线的集合构成网络或面，因此拓扑是数据处理、空间分析领域的一个极为重要的运算工具。几乎所有的重要的GIS系统都提供这样的算法。然而即使是最出名的系统，提供的算法仅是让用户使用而已。本文根据作者多年的经验，总结出这样一套C语言的算法，不敢说是目前出现的最好的算法，起码在互联网上，搜索不到比这个更精炼和优美的算法实现。

这是基于eNSP搭建的校园网拓扑，完整项目哦，可以运行。
