FAQ

General Questions

What is NEX?
The NASA Earth Exchange (NEX) represents a new collaboration platform for the Earth science community that provides a mechanism for scientific collaboration and knowledge sharing. NEX combines state-of-the-art supercomputing, Earth system modeling, workflow management, NASA remote sensing data feeds, and a web-based knowledge sharing platform to deliver a complete work environment in which users can explore and analyze large datasets, run modeling codes, collaborate on new or existing projects, and quickly share results among the Earth science communities.
Who can join NEX?
NEX is open to all NASA members and approved public members.  If you have an NDC account, you can start contributing to NEX right away.  External members will need to go through a short approval process first. External members should have a formal or informal agreement with NASA, and be involved in the fields of research that NEX covers. Please note your relationship with NASA/area of research when you register
Is there a community documentation?
There is an NEX documentation project, where users can view and participate in the community efforts to share their experiences/tips/tricks with NEX, including the computing platform. Click on the following link to go to the NEX docs project.

Log In/Registration Issues

I'm working at NASA. How do I register?
If you are a member of a NASA community, you can use your NDC account to login.
Which NASA username/password do I use?
The same username/password combination that you use to log in to your computer. NOTE: Do NOT include the "NDC\" in front of your username.
I'm not at NASA. How do I join?
You can use OpenID to join. If you have a gmail, aol, or yahoo email account, you can choose them as your openid provider. If you would like to use a work or school account, you can either create a verisign account and use that, or change your notification email address when you create your account (note: you will still use your gmail or yahoo credentials to login). Once you complete your initial registration, we will send an email to the account you used (please check your spam filters if it does not arrive). You must follow the link in the email to complete registration. After that, your name will be added to our approval queue and you will be notified when you are approved. The process should take no longer than 2 days.
I'm having issue logging in
Please make sure that you use your NDC credentials without "NDC\". If you're still having issues, contact us using the contact form with the error message you are getting and whether or not you are trying to log in with NDC or OpenID

Projects

How do I join a project?
You can join any project by clicking on the "Join" or "Request Access" link.  You will automatically be added to open projects. In the case of closed project, an email will then be sent to the project's administrator.
How come some projects have wiki/blog and some don't?
Because each project is unique. Project admins can choose what features your project has by going to edit project > features and enabling those which you think will meet your project members' needs.
What's the difference between a project admin and an editor?
In a nutshell, a project admin can do anything and everything, including deleting items in their project and kicking members out. An editor can only edit a subset of a project's attributes like its description, blog entries, and resources. Editors do not have delete permission other than for the blog entries they have created themselves.
How do I add resources to a project?
There are two ways to do this: first is by going to "add new resource" from your projects home page or resource list, or by choosing "add new" on the Resource drop down menu at the top of the page. You can then choose which project you want to associate your resource with.
Can I limit who sees my project?
Yes.  You can allow only project members to see the content of your project by adjusting the privacy settings. Be advised that your member list and project description will be visible through the "quickview" feature.

Resources

What is the difference between a project and a resource?
A project consists of many resources and members and acts as an umbrella where members can discuss events, news, and other things related to the project.  A resource is currently defined as a collection of files that can be used in a project OR as a result of a project collaboration. Examples of a resource include: a collection of datasets, or an algorithm plus a readme, or related publications.
Can I upload more than one file to a resource?
Yes. We suggest giving your files captions to make it easier for others to find what they're looking for.
What if my resources are not part of any projects?
When creating your new resource, instead of adding it to a project, you'll have the option of adding it to your "Personal Library" instead.
What if I see a resource on the site that I think my project would benefit from?
You can use the "add to" link (top right corner) and add it to your project. The item will then be available to the other members on your project's resource list.

Using the site

What are tags?
Tags are a way to categorize projects or resources yourself. Your collection of tags and tagged items will show up on your profile page and be visible to others. You can also browse projects or resources that have been tagged by others.
I have concerns about something I've seen on the site.  What do I do?
Contact the site administrators and let us know.
I have some great suggestions.  Do you want to hear them?
Absolutely.  Use the contact form to let us know what you think.  Don't be shy.
