SAHANA Overview 
The software itself is expensive running into six figures, and is being offered by Sahana Foundation for use in Pakistan for free. 
The Sahana Agasti project has seven [7] modules that address common disaster coordination and collaboration problems. Sahana Eden is being customized and localized at the moment and may have some of the same features:
Request/Pledge  Management System: An online repository where all relief organizations, relief workers, government agents and camps can effectively match requests of aid and supplies to pledges of support. It tracks aid provision from request to fulfillment.
Organization  Registry: A collaborative “Who is doing what, where” tool which enables tracking of the relief organizations and other stakeholders working in the disaster region. It captures information about the places where each organization is active and the range of services being provided.
Shelter  Registry: Keeps track of the location and basic data of shelters in the region. It also provides a geospatial view to plot the location of the camps in the affected area.
Inventory  Management: Tracking the location, quantities, expiry of supplies stored for utilization in a disaster
Situation  Awareness: Gives an overview of the event and allows people to add information on what is happening on the ground. It features the ability to plot a note and a photo with additional information on a Map, so that people can collaboratively capture the current disaster situation.
Volunteer  coordination: Helps NGOs keep track of all their volunteers, their contact information, project allocation, availability and skills to help them distribute staff resources.
Missing  Person Registry: An online bulletin board of missing and found people. It captures information about the people missing and found, and also the information of the person seeking them.
Sahana also includes  tools for synchronization between multiple  instances, allowing for responders or district offices to capture data on instances in the field and exchange the data with other field offices, headquarters or responders
