• What is GeoBrain? What is NEHEA? What is their relationship?
  GeoBrain is an open, standard compliant, interoperable, distributed, web-based, three-tier geospatial information system.The NASA EOS Higher Education Alliance (NEHEA) is an open and free alliance for promoting and facilitating the wider use of NASA EOS data in teaching and research at higher education institutes around the world, through the data-intensive Earth system learning and modeling environment provided by GeoBrain. The GeoBrain system provides a data-enhanced learning and research environment for NEHEA members. NEHEA members are the core developers and users of the GeoBrain system.
  
• Does one have to be a member of NEHEA to use this site?
  No, but being a member has the following benefits:
  1) free and prompt technical support from the development team.
  2) Immediate notice of new available products and system capabilities.
  3) Information and experiences sharing with other NEHEA members.
  
• If there is a membership option, what perks are there to becoming one?
  There is a NASA EOS Higher Education Alliance (NEHEA) membership option. Anyone can join NEHEA . NEHEA welcomes Earth Science Educators around the world to join as associate members via http://geobrain.laits.gmu.edu/join_nehea.html

• Is this data free to download or is there a fee associated with downloading?
  Yes, it is free; there is no fee associated with downloading.
  
• Can any researcher use the GeoBrain site or is it limited to those in the academic field?
  Any one can use GeoBrain site. There are no limits on usage.
  
• What are the requirements on my computer for downloading most of the data?
  Internet access is the only requirement for downloading the data.
  
• When used in projects or published works, how should this data be cited?
  Through the GeoBrain system (http://geobrain.laits.gmu.edu)
  
• Are you taking in new associates to add to the data or are you at your limit? If you are taking new associates, how do I get involved?
  The idea of this project is to provide a platform so that users can obtain not only the raw data but also information on it, and so that users can build their own models to obtain the information they need. Everybody can contribute modules and models.
  
• Is there a plan to expand the number of products available on the Web site in the future?
  Yes. This is a 5-year project. New products will be announced as they become available. Also, the GeoBrain system is a self-evolutionary system: with more users using the system and contributing service modules and models, the system will have more capabilities.
  
• Are the meetings open only to those on the team or is someone who is not on the team but is interested in the future development of GeoBrain allowed to attend?
  Anybody interested is welcome to request to attend a meeting.
  However, the final meeting attendee list is determined by the project core teams.
  
• How often are updates of data expected to occur?
  Continually. The system is self-evolutionary. The development team will make announcements about important updates.
  
• What extent does the downloadable data cover (Earth, Mars, etc¡­?)
  All of the earth
  
• Who do I contact if a link doesn't work or there are technical problems downloading the data?
  Aijun Chen (achen6@gmu.edu) or Peisheng Zhao (pzhao@gmu.edu)
  

• Web Service
  "A Web service is a software system designed to support interoperable machine-to-machine interaction over a network. It has an interface described in a machine-processable format (specifically WSDL). Other systems interact with the Web service in a manner prescribed by its description using SOAP messages, typically conveyed using HTTP with an XML serialization in conjunction with other Web-related standards." (http://www.w3.org/TR/ws-arch/)
