1. Visualize the data

1.1 NASA World Wind Virtual Globe

The global, monthly mosaics of MODIS burned areas and active fire products are available for visualisation in the 3-dimensional World Wind virtual globe. World Wind was developed by NASA Ames Research Centre, and is distributed as open source software.

Clicking on the banner below will launch the World Wind Java applet in a separate window. You will be able to visualize the MODIS fire datasets alongside with the standard World Wind datasets.

You will need the latest version of Java installed on your computer; to verify, go to the JAVA homepage. After installation, your browser might need to be restarted for the changes to make effect.

More information on how to use the World Wind Java Interface is available in the User Manual

Launch World Wind!

1.2 NASA LANCE FIRMS Web Gis System

The NASA LANCE Fire Information For Resource Management System (FIRMS) allows the visualization of the MODIS Active Fire and Burned Area datasets via a 2D Web GIS system.

2. Download the data

2.1 Reverb web interface

All MODIS products are available free of charge. The MODIS Burned Area Product is available for ordering from the Land Processes Distributed Active Archive Center (LP-DAAC) using the EOS Data Gateway web interface located at:

http://reverb.echo.nasa.gov

Additionally, an ftp server is maintained by the University of Maryland, mostly to provide support to the science users who need to download systematically large volumes of data.

2.2 FTP server

The MODIS burned area product is available for download via ftp from the website http://modis-fire.umd.edu/.

We request users to fill in a user online form for statistical purposes and in order to obtain username and password for the server. The form is available here:

http://modis-fire.umd.edu/form.html

You are asked to enter your name, affiliation and a short description of the intended use of the product. A username and password is send to your given e-mail address. Once you have received your username and password you can start retrieving the data either in HDF or GeoTIFF format.

For downloading the data via FTP you can either use your current web browser such as the FTP extension of Firefox or Internet Explorer. However we recommend using special FTP software for downloading large amounts of data. You can use freely available software such as FileZillaClient or SmartFTP, which has the advantage that you can schedule your download to start at a later time and if you download multiple sources, it will try to download different portions from them to speed up. These clients are available from here:

filezilla

smartftp

Whichever program you will use for data download you will need to connect to the UMD ftp server:

ftp://ba1.geog.umd.edu

Data Structure of the FTP server

Both data sets HDF and GeoTIFFs are available on the same FTP server. However, the subdirectory structure is different.

a) HDF Files

The file system on the ftp server is structured to organize the data hierarchically by year and by month. All the data from the same month is located in a directory identified by the year and month as:

  • /HDF/YYYY/DDD/

where:

  • YYYY is the year
  • DDD is the julian day of the beginning of the month

For example, the directory /HDF/2001/152 contains all the tiles (named with the convention explained in the user guide in section 3.1 of the user guide) of the product for June 2001.

B) GeoTIFF files

The file system on the ftp server is structured to organize the data hierarchically by window, and then by year. All the data for the same window from the same year is located in a directory identified as:

  • /TIF/WinXX/YYYY/

where:

  • XX is the number of the window (User Guide, figure 2)
  • YYYY is the year

For example, the directory /TIF/Win01/2001 contains all the months of 2001 for window 01 (Alaska).
