MODIS数据下载与处理_new
MODIS数据(1B、产品、常用处理软件)免费下载
1、MODIS 1B数据下载
L1B数据下载地址：https://www.360docs.net/doc/885895093.html,/data/search.html
打开网页，选中需要的数据源类型
注意：其中，MOD03数据是用于对1KM,QKM,HKM数据进行几何纠正所用。别忘记下载。其中，日期类型为：月/日/年时:分:秒
其中，网页中显示的时间为UTC时间，换算为北京时间为：UTC时间=北京时间-8小时。因此，要获得1月16日的数据则范围为：01/15/2003/ 16:00:00~01/16/2003/ 16:00:00
在‘spatial selection’选项中选择“latitude/longtitude”,按经纬度形式选择影像范围。
点击’search’查到需要的数据：
据。(如果要搜索多天数据，可以选‘add files to shopping cart’继续搜索其他日期的数据。
所订购数据的存放位置信息：
点击‘Data->Track Orders ’可以查看所有已订购的数据的状态。
如果’state’显示‘avalable’即可开始下载。
ftp:https://www.360docs.net/doc/885895093.html,
username: anonymous
password: rainaleaf@https://www.360docs.net/doc/885895093.html,（自己申请数据的邮箱）一般使用FTP下载工具下载。
首先新建站点：
的框中，开始下载数据。
OK！
2、MODIS产品下载地址
https://https://www.360docs.net/doc/885895093.html,/api//u515127/u515368/u515406/u515421/u515529/u516066/u516091/u
516110/u516150/u516307/u517021/u517029(要装IE7支持)
或已知所下载文件名的modis09~17数据可以从FTP上下载：
ftp:/https://www.360docs.net/doc/885895093.html,
tarra的数据放在MOLT里。Aqua 数据放在MOLA。上述的搜索网站（https://https://www.360docs.net/doc/885895093.html,）（如果遇到能查到数据但是下载不了的情况，也可以在FTP中通过查找与该数据相同日期同轨道号来下载。）在网站查到该数据的好处是能查看数据的覆
盖区域。可以查看覆盖范围。
假如：MOD11A1.A2008288.h28v06.005.2008290030125.hdf 从：
ftp://https://www.360docs.net/doc/885895093.html,/MOLT/MOD11A1.005/2008.10.14/查找到2008-10-14 轨道号为H26V05,就从里面的文件夹里选出来下载就可以了。一般使用FTP下载工具下载。
注：数据的轨道号：
（H27V05、H27v06, H28V05、H28v06四块组成）
3、常用的MODIS软件：
常用的MODIS查看软件还有：
a、MODIS explorer（推荐使用）其下载地址：
https://www.360docs.net/doc/885895093.html,/software/HDFExplorer/或：
https://www.360docs.net/doc/885895093.html,/，该软件可以方便查看HDF格式的MODIS元数据或信息。
b、modis swath tool（推荐使用）
可用NASA网站提供的modis swath tool 对HDF格式的1B数据进行几何精纠正（下载地址：https://www.360docs.net/doc/885895093.html,/pub/imswelcome/），该软件使用MOD03数据对影像进行纠正，处理速度快且使用简单方便。比直接用ENVI的Georeference 更好用。（好像也可进行影像拼接）
C、MRT（推荐使用）
可以用来对下载的hdf格式的MODIS产品进行重投影等,下载地址：https://www.360docs.net/doc/885895093.html,/pub/imswelcome/）。

4、MODIS 1B数据需处理的过程（几何纠正，DN转反射率，拼接）
1、几何纠正
1、安装从网站上下载MODIS Swath tool 软件(用于1B数据的几何纠正，下载地址：
https://www.360docs.net/doc/885895093.html,/pub/imswelcome/需要注册（免费）才能下载) 以及java 软件。并安装，安装方法与MODIS tools相同。
2、然后从安装路径中ModisSwathTool.bat，打开MODIS swath tool,’Open input file …’，打
开下载的1B数据。
3、从菜单‘file’->’open geolocation file’打开与该数据想配套的03级数据。
4、设置投影参数：
点击‘edit Projection Parameters …’修改参数：
然后点击”run”,几何纠正开始。
1、几何纠正完成后即可用ENVI打开：
