presentation outline
Presentation Outline
  • Enterprise approach to data distribution
  • Product Distribution and Access (PDA) system overview.
  • User level interaction:
    • User interface examples (under refinement)
    • Subscription process (sequence diagram)
    • Search and ad-hoc data request process (sequence diagram)
  • PDA capabilities
  • Timeline
  • Summary
  • Q&A
enterprise distribution approach
Enterprise Distribution Approach
  • TODAY
    • Environmental Satellite Processing Center (ESPC) distributes data from several different systems: DDS, McIDASADDE servers, AWIPS GINI, ftp services, etc.
  • WHY CHANGE?
    • Need to distribute large data volumes from new missions
    • Want to leverage latest technology improvements, and build in scalability
    • Required to improve IT security posture
    • Have to handle data management challenges
  • THE FUTURE
    • Product Distribution and Access (PDA), an enterprise solution.
    • An enterprise distribution system will:
      • allow authorized real-time users to manage their data subscriptions and delivery
      • allow those users to tailor their data requests to meet their specific needs
      • enable ESPC to proactively manage data volume usage
enterprise distribution approach1
Enterprise Distribution Approach
  • Uses a PROVEN CONCEPT:
    • Adapted from data centers that deliver data with less stringent data latency requirements.
    • Replaces the traditional, mission-specific “point to point” real-time delivery approach.
  • Implements data management FLEXIBILITY:
    • NESDIS real-time authorized users can manage their unique data delivery needs.
    • Meets time-critical delivery requirements.
    • Provides a secure and scalable enterprise system framework.
    • Simplifies operations and maintenance for ESPC Operators.

PDA User Interfaces (examples)utilize Google Web Toolkit (GWT)
  • User authenticates or a new user can register for account activation – subject to NESDIS’s data access policy.
  • Once the user is approved and authenticated, they are able to log into the system and are dropped onto a landing page.
  • Menu options
  • System announcements and user specific notifications.

Create new data subscriptions

- Receive data by pulling from provider

- Receive data pushed by provider

  • Fulfill data subscription by pushing to subscribers
  • Fulfill data subscription by notifying data available for pull

Sectorizing

Remapping

Translation

  • Remapped to:
  • Lambert Conformal
  • Polar Stereographic
  • Mercator
  • Platte Carre

With GOES-R ABI-based products being delivered in fixed-grid coordinates, remapping to user specifications on PDA can be implemented in a CPU-efficient look-up-table application, saving resources and avoiding latency impacts.

  • Sectorizing - geographic sub-setting
  • File sub-setting – layer extraction
  • Remapping and resolution reduction
  • Bit-depth scaling
  • File translation (NetCDF McIDAS)

pda capabilities1
PDA Capabilities
  • Create a Region of Interest
  • define the region bounds or
  • define center and extent of region
  • define if data exists within region or
  • define if data overlaps
  • save user defined region or
  • select an existing region to use.

Sustainment/Ops Support

Inform users of PDA capabilities as outreach (now).

Provide training information and HOWTOs to users – early 2014.

PDA system assumes data distribution in parallel with legacy distribution systems – late 2014.

Summary

  • PDA:
    • represents a new paradigm shift in NESDIS’s capability to deliver data to our real-time users.
    • enables users to manage their data subscriptions.
    • provides event responders with in-depth data discovery and a powerful search capability.
    • enables ESPC to manage its entire product distribution from a single enterprise system.
  • PDA timeline key milestones:
    • inform users of the system’s capabilities (now)
    • provide user level training (mid-2014)
    • transition the system to operations (late-2014)
