Enabling Use of Government Tabular Data in a Geographic Context

U.S. Federal Geographic Data Committee 2009 CAP Grant, Category 4

FGDC Cap Grant, Category 4

• Easy and productive access to geographic, tabular government data

• Reference location by Address, Code, or Coordinates

• Shared Public Web Service

• Discoverable, Accessible, and Applicable to geographic contexts

Project Goals

• Enable more data to be consumable in a geographic context

• Increases in geo-enabled data will cause an increase in demand for geographic applications and education

• Geo-enabled data creates a positive externality for the entire ecosystem of agencies and companies that leverage or provide geospatial technologies

• Mapping should be an option for every data work flow when there is a geographic component available (80-90% of the time)

• Make data available to a variety of workflows (spreadsheet data to GIS and GeoWeb) and provide dynamic loops (GIS data back to spreadsheets and GeoWeb) allow for collaboration and data sharing

Proposed Solution

• Deliver a platform to provide easy georeferencing of non-spatial data

• Quality Assurance and Error identification and remediation of contributed datasets

• Catalog and store taxonomy of existing boundary data sources

• Add OGC Catalog Services for the Web (CSW) support

CAP Added Capabilities

• GeoCoding Engine for Street Address georeferencing

• GeoJoin Engine for polygonal region georeferencing

• Spatial, hierarchical aggregation

• Federated search and discovery

• OpenSearch and GeoRSS

• OGC Catalog Services for the Web (CSW)
