3. Background Current effort an outgrowth of a National Spatial Data Infrastructure (NSDI) Cooperative Agreement Program (CAP) project -
Developed reference implementation of the National Hydrography Dataset (NHD) through a CubeWerx Web Feature Service (WFS)
New profile of Geography Markup Language (GML) for easy access geospatial information (GMLsf)
Collaboration of geoLeaders, CubeWerx, The Carbon Project, EPA and USGS
4. Implementation of the NHD via WFS successfully demonstrated that NSDI based on open standards is feasible - Effort resulted in the current project
Background
5. Goals of Current Project Fulfill vision of the NSDI, enable operational NSDI Framework Data Services based on ANSI and OGC standards.
Implement key improvements to make WFS a viable platform for operational NSDI applications
Provide key support to the tapestry that weaves together a national geographic information system of systems
Propel the United States into a leadership position in the implementation of interoperable spatial data infrastructures for E-Government
6. Key Tasks Task 1 - Operational NSDI Framework Data Service for the Hydrography, Transportation & Governmental Units Framework Data Themes
Task 2 - Automated Transactions to Update Operational NSDI Framework Data Service
7. Task 1 Overview Deploy operational NSDI Framework Data Service for the Hydrography, Transportation & Governmental Units Framework Data Themes as OGC Web Feature Services
Implementation & Loading for Transportation & Governmental Units in addition to the National Hydrography Dataset
Deploy as operational NSDI Framework Data Services
Validate GMLsf Profiles defined for the Framework Data Themes as part of the CAP Grant Program
Review Hydro/Gov Units/Transportation schemas
Validate against UML, validate against GMLsf Level 1
8. Task 2 Overview To make the use of the Framework Data Theme Web Feature Services viable for operational applications
Implement an automated transaction-based update process
Maintain integrity, currency and consistency of the CubeWerx WFS with maintenance/production systems based on ESRIs Geodatabase
This component includes working with the USGS to coordinate the Transaction capability

10. Framework Themes Seven core data themes are considered Framework Data of critical importance to the NSDI
Geodetic Control
Orthoimagery
Elevation and Bathymetry
Hydrography
Cadastral
Governmental Units
Transportation (Air, Road, Rail, Transit, Waterways)
Geographic names (GNIS) also available
14. ANSI Framework Standards Supports the exchange of geospatial data
Seeks to establish a common baseline for the semantic content of databases for public agencies and private enterprises
Seeks to decrease costs and simplify exchange of data among local, Tribal, State, and Federal users and producers and discourage duplicative data collection
Benefits include the long-term improvement of the geospatial data through the establishment of Web data services for data and maps within multiple communities
15. ANSI Framework Standards Concise documentation of Framework Data content needed to support the intersection of stakeholder requirements
Includes conceptual/abstract model of the feature types, attributes, relationships, identifiers in UML
Includes appropriate description of all elements and a narrative to provide scope and context for its use
Includes an informative annex describing the encoding of the model in XML/GML including an XML-Schema document to facilitate validation of data
18. Overview of the Hosting Service Online services to efficiently store, manage and provide web-based Access for high volumes of Framework data at multiple resolutions
Optimized for online delivery and based on OGC Web Feature Server (WFS), Filter Encoding (FE) and the Geography Mark-Up Language Simple Features (GMLsf) Specifications
Data in ANSI Framework Standard for common community framework

25. Massively scalable online spatial data warehouse
Web Feature Service technology for Web-based access using HTTP as distributed computing platform
Integrate ANSI Framework Schema, GMLsf and Transaction-based updates
Capacity to dynamically navigate through all of the providers data sources as well as fuse data layers from multiple remote data sources and types (Cascading WMS)
Based on CubeWerxŽ Suite
Design
26. CubeSTORŽ Spatial Warehouse
Highly scalable Spatial Warehouse that handles massive amounts of all types of geospatial data
Built on Oracle, used to store, manage, access and publish geospatial data (vector, matrix and imagery) over the Web
CubeSERVŽ Web Feature Server
CubeSERV Feature Server builds on the CubeSTOR, providing a web-based service for spatial data delivery on the Web
Implemented using the latest OGC Web Feature Server (WFS), Filter Encoding (FE) and the Geography Mark-Up Language Simple Features (GMLsf) Specification Major Components
27. Key Points on GMLsf GMLsf Level 1 defines a simple profile of GML for encoding geographic features
GMLsf Level 1 enables distributed geospatial architectures
Supports enterprise information system for the Nations geospatial assets
Enables distributed network of data stewards to implement the NSDI
Lets NSDI users create map products and geographic knowledge
28. Why GMLsf? Greatly simplifies development of NSDI-based applications
Makes it easy to use GML and WFS in multiple applications
Can be integrated into new applications on network-connected mobile, desktop and multi-media platforms
Some potential applications for hydrography, transportation and governmental boundaries content in GMLsf include
natural resource management
crisis management and situational awareness systems
environmental site assessments and impact statements
risk and vulnerability assessments
many others
