Description: ：World Wind是NASA发布的一个开放源代码的地理科普软件，由NASA Research开发，NASA Learning Technologies来发展，它是一个可视化地球仪，将NASA、USGS以及其它WMS服务商提供的图像通过一个三维的地球模型展现，还包含了火星和月球的展现。软件用C#编写，调用微软SQL Server影像库Terrain Server来进行全球地形三维显示。它通过将遥感影像与SRTM高程（航天飞机雷达拓扑测绘）叠加生成三维地形。-: World Wind is NASA released an open source geographic science software developed by the NASA Research, NASA Learning Technologies to develop, it is a visual globe, will be NASA, USGS and other WMS services provided by a three-dimensional image Earth model shows, also includes display of Mars and the moon. Software written using C#, call the Microsoft SQL Server Image Database Terrain Server to display the global three-dimensional terrain. It is through the elevation of remote sensing images and SRTM (Shuttle Radar Topology mapping) stack generate three-dimensional terrain.

Description: 读取高程数据的MATLAB程序,经过测试，很不错的，希望对大家有帮助- read_SRTMtile: returns lon, lat, & height (height in meters) SRTM 3-arcsec data
USE: [vlon vlat vhgt] read_SRTMtile(filename,sc)
INPUT:
filename: filename, e.g. s23w041.hgt
sc: spot check, any value here will produce a low resolution
image of tile (note: image rendering can be time consuming)
OUTPUT:
vlon: cell longitude
vlat: cell latitude
vhgt: cell height (in meters)
NOTES:
+ SRTM 3-arc sec data can be downloaded from:
http://dds.cr.usgs.gov/srtm/version2_1/SRTM3/
(as per http://www2.jpl.nasa.gov/srtm/)
+ filename is parsed to obtain lower left (LL) coordinates of tile
(as per quickstart.pdf doc in:
http://dds.cr.usgs.gov/srtm/version2_1/Documentation/
File names refer to the latitude and longitude of the lower
