Description: srtm是美国nasa指定的精度为90米的全球高层数据，函数srtmshow可以利用matlab读取这样的数据，并且以mesh的形式显示他们。用法：srtmshow（‘c:/.../XXX.ttf’,60,70,60,70）。表示读取文件XXX.ttf中横向60 -70 ，纵向60 -70 的数据并显示他们。
-srtm the United States designated the accuracy of nasa' s global top 90 m data, the function srtmshow can use matlab to read this data and to display them in the form of mesh. Usage: srtmshow (' c :/.../ XXX.ttf' , 60,70,60,70). That read the file XXX.ttf 60 -70 in the horizontal, vertical 60 -70 of the data and display them.

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
