 +MODIS Level 1 and atmosphere products are available through the Level 1 and Atmospheric Archive and Distribution System ​LAADS). [[http://​ladsweb.nascom.nasa.gov/​]] ​ Level 1 products include raw radiance and calibrated radiance images. Raw digital number images are also available through order. All of the images in their archive are free of charge. ​ 
 +\\ \\ 
 +Level 2 and 3 Land Products are available through Nasa’s Warehouse Inventory Search Too (WIST) and the Land Processes Distributed Active Archive Center (LPDAAC) Data Pool at the U. S. Geological Survey EROS Data Center (EDC). https://​lpdaac.usgs.gov/​get_data ​ Examples of level 2 and 3 products are land cover, leaf area index, surface temperature,​ and burned area. All products on a specific temporal schedule are archived and available free of charge to the general public. Detailed instructions on how to acquire MODIS  data through the LPDAAC Data Pool are here: [[https://​lpdaac.usgs.gov/​sites/​default/​files/​public/​get_data/​docs/​DP_Tutorial.pdf]]. 
 +\\ \\ 
 +Another source for MODIS data is the Global Land Cover Facility. [[http://​www.landcover.org/​data/​modis/​]] They offer several vegetation products ​ made from 16-day and 32-day composite images. The products come in a GeoTIFF format which can be easier to work with in a geographic information system.

-===== Image format ====== +===== Image Format ​===== 
-Format and delivery options for imagery from this sensor+MODIS data from NASA/USGS are distributed in the Hierarchical Data Format ​(HDF-EOS). This format can be reprojected or converted into other formats such as GeoTiff, but in the past HDF-EOS has been notoriously difficult to work with. Recent versions of ArcGIS (e.g., version 9.3) can read the HDF-EOS format. A listing of some other tools that can be used to view and convert HDF-EOS images can be found at [[https://​lpdaac.usgs.gov/​tools]],​ but be cautioned that most of these tools are not easy to implement.

-Links to projects or references ​of where data from this sensor was used in a rangeland projectDoesn'​t need to be an exhaustive listjust an example or two of where/how it was used+  * Reeves et al (2001) discusses the use of MODIS images ​to study rangeland productivity  
 +  * Reeves et al (2006) studied the net primary productivity ​of North Dakota grasslands with MODIS image products 
 +  * Kaurivi et al (2003) compared MODIS based enhanced vegetation index with temperature and rainfall patterns ​in a semi-arid region 
 + 
 +=== Online applications of MODIS data === 
 +  * RangeView http://​rangeview.arizona.edu/​RangeView,​ developed by the University of Arizona is a web based tool that helps land managers visualize biophysical conditions across the landscape. Tools within the site allow the user to view MODIS derived vegetation indices and other mapping layers in a format similar to a geographic information system. A series of images can be animated to show how conditions change over time.  
 +  * Geospatial Multi-Agency Coordination (GeoMac) www.geomac.gov - GeoMAC is an internet based mapping application that shows current and past fire locations and perimeters in the conterminous U.S. and Alaska. Users can view fire maps a different scales and print them for use in resource decision making on the ground. ​ MODIS thermal anomaly and fire productsacquired twice daily, are displayed in this mapping tool. 
 +  * USFS Active Fire Mapping (http://​activefiremaps.fs.fed.us/​) - This site is similar to GeoMAC in that it displays current fires derived from MODIS fire products on a map of the U.S. The mapping tool also displays forecasted fire danger throughout the country.
  
 ===== Software/​Hardware Requirements ===== ===== Software/​Hardware Requirements =====
-Any special (or helpful) software or hardware requirements ​for using this kind of imagery (e.g., converters for reading NASA HDF format ​and saving ​data to a more user-friendly format) ​ +Java is required ​for viewing ​and selecting ​data in the LPDAAC Data Pool.

-===== Sample Image ===== +MODIS images can be converted into GeoTiff format making is compatible with ESRI ArcGIS and other GIS platforms. The images can be manipulated and processed in remote sensing software packages such as ENVI and ERDAS Imagine.
