    v4 v5  
    55This is proposed to be done using the [wiki:BluePrint/GIS/SOSLayers SOS Layer].
    66
    7 ==== Model ====
    8 Storing different positions of objects (and some other dynamic information) related to time into the database (first/past/current/forecasted
    9 positions)
     7== Introduction ==
     8At times of an emergency it may be improbable to expect volunteers/staff to check in with a superior in the Emergency Response Team but the incident commander is required to know the status of his deputies to make effective and efficient decisions. The objective here is to provide just that, the ability to locate objects and staff on a map without any manual communication with the person involved.
    109
    11 ==== View ====
    12 Display position tracks of objects or object groups on maps, additionally indicate or link other data (such as speed and course, or even
    13 non-discrete such as triage/recovery status, member count in groups, free-text, wiki-text, or other URL)
     10=== Added Value ===
     11-Instantaneously access location information of resources on a map
     12-Location information in the form of images to put across information cognitively
     13-Improve inter-organization and intra-organization co-ordination at the site of incident
    1414
    15 ==== Backend ====
    16 Take up position data of the objects in real time and update the database. This may be multiple controllers
     15== Stakeholders ==
     16=== Benefits ===
     17-All the users of Sahana-Eden(ie. Government Organizations, NGOs, Volunteers)
    1718
    18 ==== Client system ====
    19 Capture and send real-time position/object data to the backend (e.g. from a mobile phone), this could happen via HTTP, URL
     19=== Affects ===
     20The developers of Sahana-Eden, requires additional code implementation in Model,View,Backend and Client System(elaborated below)
     21
     22== User Stories ==
     23
     24-Member of a NGO Emergency Response Team at the site of a flood taking part in rescue operations, enters a perilous zone and immersed in his task does not hear his alert go off, and finds himself in an unfortunate situation. Another member tracking his movements notices this and informs concerned authorities so that necessary directions can be passed down the command structure.
     25
     26-A volunteer goes offline and is out of reach of all communication efforts from the incident command center, tracker maybe used to review the volunteers last movements while still online and search efforts may begin in the forecasted position zones.
     27
     28== Requirements ==
     29
     30=== Functional ===
     31-Use GeoFencing to trigger notifications when users enter perilous zones.
     32
     33-Authorize user check permissions to allow viewing of tracking details (If making use of existing framework no work is required but in case of writing custom functions to access the database, relevant framework functions maybe used to maintain security)
     34
     35-Add a function to modules/s3/s3gis.py or static/scripts/s3.gis.js to generate forecasted position
     36
     37-Take up position data of the objects in real time and update the database. This may be multiple controllers
     38
     39-Capture and send real-time position/object data to the backend (e.g. from a mobile phone), this could happen via HTTP, URL
    2040(RESTlike controller), SMS, E-Mail, file transfer (CSV or XML), or other/multiple methods - but should be as easy, portable and reliable as
    2141possible.

    23  * Example UI: http://www.opengts.org
     43-Display position tracks of objects or object groups on maps, additionally indicate or link other data (such as speed and course, or even
     44non-discrete such as triage/recovery status, member count in groups, free-text, wiki-text, or other URL)
    2445
     46-Enable users to check-in/check-out through SMS refer to http://eden.sahanafoundation.org/wiki/UserGuidelines/Messaging
     47=== Non Functional ===
     48-Store different position-related data like average speed,current position,past position(before a certain time interval),approximate direction of movement
     49    -The framework required to store position along with timestamp is present here.[https://github.com/flavour/eden/blob/master/modules/s3db/gis.py#L95 ]
     50   
     51    -All other attributes are to be made part of a different table which can then be made a 'component' of the main table here http://eden.sahanafoundation.org/wiki/S3/S3Model/ComponentResources
     52
     53-Documentation
     54
     55== Design ==
     56=== Technologies ===
     57-Python
     58
     59-Web2Py Framework
     60
     61-Jquery
     62
     63-OpenLayers (For advanced features)
     64
     65== Future Extensions ==
     66-Enable the use of TimeSlider proposed in another GSOC Project
