Geospatial Web Services

• Over the past ten years the FGDC has been promoting online sharing of government data using Web Services

• Helped formulate the first OGC “Testbed” in 1999 to evolve a common Web Map Service specification

• OGC WMS is now the most commonly adopted geospatial Web Service, allowing neutral requests to multiple map servers

NSDI CAP Programs

• Supported establishment of geographic Web Services by State and Local government– 2004: WMS– 2005: Web Feature Services for Framework– 2006, 2007: Framework client development– 2008: Best practices in geospatial SOA– 2009: GOS Catalog- Use of GOS Map and

Data Services

Geospatial Line of Business

• Geospatial data lifecycle, A-16 “Framework+” data definitions and stewardship, governance

Multi-Tier Architecture

Suitable for deployment in agency or commercial data center and Cloud environments

Suitable for deployment in agency or commercial data center and Cloud environments

GeoCloud Initiative• One-year project to test and monitor externally-hosted

Cloud data and service solutions for the geospatial domain, sponsored through the Geospatial LoB

• Anticipated outcomes:– Identify requirements-driven solution architectures for various

sized deployments of geospatial data and services– Document and assess cost models to support scalability,

reliability, and redundancy– Expedite FISMA certification and accreditation for agency

adoption of packaged solution architectures– Support and collect cost comparison information from

agencies for existing and externally-hosted Cloud solutions

Notional Cloud Computing Stackhttp://en.wikipedia.org/wiki/Cloud_computing

• GSA apps.gov will be offering Infrastructure as a Service (IaaS) solutions for acquisition• This is roughly equivalent to “shared-hosting” of raw computers with an operating system in the Cloud domain

Platform as a Service (PaaS)“A cloud platform (PaaS) delivers a computing platform and/or solution stack as a service, generally consuming cloud infrastructure and supporting cloud applications. It facilitates deployment of applications without the cost and complexity of buying and managing the underlying hardware and software layers.”

The GeoCloud intends to pilot the deployment of candidate services or solutions architectures (suites of software) on top of the GSA IaaS to provide common geospatial capabilities. GSA will venture into PaaS next.

Services and the Cloud

• Direction from CTO and OMB to:– Deploy services (PGFSOA)– Place data online (data.gov)– Evaluate cloud provisioning for federal IT

• Federal geospatial resources are key:– Large data volumes– Complex information content with high value– Analytical capabilities, data structures, and

Web Services are standardized
