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:5efca9eaf8c75fbfc77db2e0/data/search

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。

老刘的研究:32-34,120-122

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:5efca9eaf8c75fbfc77db2e0

username: anonymous

password: rainaleaf@5efca9eaf8c75fbfc77db2e0(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://5efca9eaf8c75fbfc77db2e0/api//u515127/u515368/u515406/u515421/u515529/u516066/u516091/u

516110/u516150/u516307/u517021/u517029

或已知所下载文件名的modis09~17数据可以从FTP上下载:

ftp:/5efca9eaf8c75fbfc77db2e0

tarra的数据放在MOLT里。Aqua 数据放在MOLA。上述的搜索网站(https://5efca9eaf8c75fbfc77db2e0)(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://5efca9eaf8c75fbfc77db2e0/MOLT/MOD11A1.005/2008.10.14/查找到2008-10-14 的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。

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:

5efca9eaf8c75fbfc77db2e0/software/HDFExplorer/或:

5efca9eaf8c75fbfc77db2e0/,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:5efca9eaf8c75fbfc77db2e0/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:5efca9eaf8c75fbfc77db2e0/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:

5efca9eaf8c75fbfc77db2e0/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:

前的数据查看该数据scale_offset值。
