1 Technical Deployment Task Team (TDTT) Recommendations Steven Jackson FGDC Core Team Telecon 04 APR 2011
2 Agenda Background Notional Technical Architecture Candidate Components Candidate Interfaces Contributing Data and Services Geospatial Platform V0 Next Steps
3 Bottom Line Up Front The TDTT’s work is only the beginning The team identified some potential next steps The proposed notional architecture Leverages existing capabilities heavily Decentralizes data/services storage Centralizes discovery Will require funding to support centralized components Open standards are key to implementation of the architecture
4 Background Origin: Assembled December 2010, as a functional team comprised of representatives nominated by FGDC partner agencies and the Geospatial Platform Core Team Purpose: Recommend a path forward for implementation of Geospatial Platform common services and shared infrastructure Lead efforts to deploy "mature" capabilities identified in the Modernization Roadmap for the Geospatial Platform that provide a useful service, can be built upon, and can be undertaken quickly
5 Background Approach: Develop a set of requirements by evaluating existing Federal geospatial capabilities to determine their potential to meet the needs of the Geospatial Platform Outcome: Generate a Technical Deployment recommendation for the Geospatial Platform Core Team and FGDC Executive Committee which will include: Notional technical architecture Candidate solutions architecture(s)

8 Background Team Members: Chair: Steven Jackson, NGA - Steven.P.Jackson@nga.mil Myra Bambacus, NASA - firstname.lastname@example.org Jeff Booth, DHS - Jeffrey.Booth@dhs.gov Paul Fukuhara, USDA - email@example.com Travis Hardy, DHS - Travis.Hardy@associates.dhs.gov Doug Nebert, FGDC - firstname.lastname@example.org Kari Sheets, NOAA - Kari.Sheets@noaa.gov Michelle Torreano, EPA - Torreano.Michelle@epamail.epa.gov
9 Notional Technical Architecture – Use Case Casual User This use-case describes the process of a casual user discovering and accessing data from multiple sources and displaying them together in a map for visual or print usage.
10 Notional Technical Architecture – Use Case Advanced User This use-case describes the process of an advanced user discovering and accessing data from multiple sources and applying them in a personal computing environment.
11 Notional Technical Architecture – Use Case Publisher This use-case describes the process of a publisher registering a data, service, or application resource into a platform catalog. A-16 Portfolio Designation is also handled within this use case.
12 Notional Technical Architecture – Use Case Geospatial Viewer This use-case describes the basic functionality to be included within the Geospatial Viewer with a focus on the base map content.
13 Web Metadata Editor Web Metadata Editor Federal (blue) and non-federal (green) geospatial metadata catalogs Geospatial Catalog Geospatial Catalog Geospatial Viewer Geospatial Viewer Geospatial Query UI Geospatial Query UI Geocoder Service Geo-Enabler Tool Geospatial Assets GeoPlatform Web Presence Geoprocessing Services Phase IPhase II Geospatial DSS Workbench Geospatial DSS Workbench metadata Data.gov Catalog Data.gov Catalog Synchronized Dublin Core Metadata View FGDC/ISO Metadata View queries results with links metadata as XML harvest Distributed search FGDC/ISO metadata as XML plus data dictionary RDF metadata links to assets sends links asset display and query uses extends accesses Notional Technical Architecture
14 Contributing Data and Services The Notional Technical Architecture is component- based Open standards based components can be changed Offers partners an opportunity to interact with the Geospatial Platform at several levels The Geospatial Platform is an environment where Partners are able to share their content and gain access to the work of others while reducing their own operating costs
15 Contributing Data and Services Publishers expose content (“the give”) in the Geospatial Catalog using the Web Metadata Editor Focus is on public data/services. Each data/service maintains host user credentialing Content is discovered through the Geospatial Query UI Mappable data is passed to the Geospatial Viewer while other content is provided to the user for download Publishers can register their catalog to support content search/harvest
16 Contributing Data and Services Partners discover and use content (“the get”) within the Geospatial Platform or other within their own capabilities Partners contribute their specific content to the Geospatial Platform and at the same time seek the specific content of others Integrate data/services into their own environment to enhance their own mission Minimize duplication
17 Contributing Data and Services Web Metadata Editor Web Metadata Editor Federal (blue) and non-federal (green) geospatial metadata catalogs Geospatial Catalog Geospatial Catalog Geospatial Viewer Geospatial Viewer Geospatial Query UI Geospatial Query UI Geospatial Assets GeoPlatform Web Presence Geocoder Service Geo-Enabler Tool Geoprocessing Services Phase IPhase II Geospatial DSS Workbench Geospatial DSS Workbench metadata
18 Geospatial Platform V0 Deliverable of the TDTT was to stand up an initial instantiation of the Geospatial Platform Team members examined “mature” capabilities for suitability Version 0 developed to demonstrate Architecture Intentionally integrated components of several organizations Intended to facilitate detailed feedback and discussion
19 Web Metadata Editor Web Metadata Editor Federal (blue) and non-federal (green) geospatial metadata catalogs Geospatial Catalog Geospatial Catalog Geospatial Viewer Geospatial Viewer Geospatial Query UI Geospatial Query UI Geocoder Service Geo-Enabler Tool Geospatial Assets GeoPlatform Web Presence Geoprocessing Services Phase IPhase II Geospatial DSS Workbench Geospatial DSS Workbench metadata GEOSS Clearinghouse (GeoNetwork) GEOSS Clearinghouse (GeoNetwork) Spatial Web Portal OpenLayers MERMAid Geospatial Platform V0 MERMAid GeoNetwork MERMAid GeoNetwork
20 Next Steps Identify what Metadata Catalog attributes or triggers can be used to identify a base map record for the Geospatial Viewer. Work with the Geospatial Viewer to expose the base maps. Identify what Metadata Catalog attributes would be required to facilitate A-16 Portfolio Management. Add those attributes to the Metadata Catalog. Additionally, need to document the reporting mechanism functionality through a Use Case.
21 Next Steps Integrate the Status Checker into the catalog so that it can populate an attribute which will allow users to quantify the reliability of the service which they are looking to use. The initial data content for the Geospatial Catalog must be identified and then integrated into the Catalog.
22 Next Steps Need to investigate how the National Map can be used by the Geospatial Platform. Can the National Map be a destination for services found within the Geospatial Query UI? Can it be the/a Geospatial Viewer? Need to investigate implementation of Phase II of the Geospatial Platform Web Presence. The FCC’s Broadband Map would serve as good test candidates because they are completed and standards-based.
23 Next Steps The current architecture enables each organization to maintain their own user access and logging. Investigate the degree to which single sign-on is feasible or desired within the community. Publicly available data need not be access controlled.
24 Next Steps Integrate the Status Checker into the Geospatial Catalog so that the long-term reliabilities of the services can be captured and used as a query property.
25 Summary TDTT’s work should be used As base material for subsequent Task Teams Reference next steps To communicate the desired end-state to partners and developers of the Geospatial Platform Use Cases Notional Architecture As the foundation for the Geospatial Platform
