GNIS/Vector Problem Statement Problem statement: The Geographic Names Information System (GNIS) was developed pursuant to statutory and business requirements of the U.S. Board on Geographic Names with regard to national standardization of feature names and locations. Additional requirements have developed concerning federal and national standardization of geographic feature record identifiers and associated geolocation codes. The National Vector System is under development in response to requirements of The National Map. Additional requirements are being defined in order to support the Graphics production process. For the most part, these requirements overlap or are mutually supporting. Current TNM operations feed feature data into the two separate systems. This situation results, in the accrual of operational and maintenance costs for two separate data ingestion and update processes, as well as the need for additional processes to reconcile and resolve differences between data in the two systems. This also creates a need to coordinate the planning and execution of data collection contracts and agreements for Names and Vectors. Integration the current GNIS & Vector databases and acquisition applications

Project Scope (today) GNIS Acquisition Names Management Modifications and New Names Metadata Source Originator (form biblio) Auditing Transactions Delivery GAZ Support Services GNIS Shape Files GeoNames Services Database Oracle Database Web Forms PL/SQL Procedures Some Oracle Spatial
5
Project Scope (today) Vector ( NHD, Structures, Boundaries, and Transportation ) Acquisition Names Management New Names Structures Vector/NHD Stored Names Metadata Source Originator Process Description Auditing Transactions Delivery Vector Extracts Personal/File GeoDatabases Pre-defined Model Structure Viewer Services Database Oracle Database ArcObject.Net Tools ArcObject.Net Applications SDE GeoDatabase
6
Project Scope (today) Vector / GNIS Problem breakdown Acquisition Separate applications GNIS Forms/ Geo Edit Tools No consistent verification process to acquire spatial representations GNIS Coordinates does not always represent the true spatial representations Timing New Name acquisition Metadata stored as a different format Delivery Inconsistent results on delivery to GNIS and Vector Community Duplicates Representation Same GNIS ID w/Two different Names (GNIS/Vector) Spatial Representation (Shape / Lat Long Coordinates) Spatial Representation (Spatial Accuracy) Service Representation GNIS and Gaz Services No Vector representation Vector (NHD) Viewer min GNIS presents TNM (Represent both as two entities)
7
Project Scope (today) Vector / GNIS Problem breakdown (cont) Delivery (cont) Extracts Different formats GNIS is not part of the Vector Model GNIS is not delivered with Vector Extracts Vector is not delivered with GNIS Database Two separate databases Inconsistent results Stored in Database Duplicate representation Same GNIS ID w/Two different Names (GNIS/Vector) Spatial Representation (Geometry Shape / Lat Long Coordinates) Spatial Representation (Spatial Accuracy)
8
Project Scope (today) Target Solution Acquisition Consistent Acquisition set of Tools or Applications One consistent validation process Attrib and Spatials True Spatial representations Timing Issue is no longer Metadata Format Gaz points derived Delivery Consistent results on delivery to GAZ and Vector Community Service Representation GNIS/Gaz Services and Vector (NHD) Viewer, TNM Viewer Fully represented Extracts Same delivery formats GNIS part of the Vector Model GNIS/Vector is delivered together
9
Project Scope (today) Target Solution (cont) Database One databases Consistent results Stored in Database No Duplicate representation Data Integrity Spatial Representation (Shape Only) Spatial Representation (Valid Spatial Accuracy) Stored Metadata Format

Development Scope Integrate Database Phase (Migration) Migrate GNIS into a Integrated Database Min adjust front-end and back-end process and applications June 1st implementation To Be Phase Develop or Modify Acquisition tools or applications Develop or Modify the Delivery methods 2009 EOFY implementation Full conflation (when Unknown?) Why Phase Approach Lots of Resources to Conflate the Vector DB and GNIS Approach Benefit Database Integrated Application and Tools Integrated (by EOFY) New and Modified transactions will be conflated Full conflation can take place (existing features)
11
Impacts on the User Community No substantial interruption of current business processes, product and service delivery. Examples: Coordination of data collection operations Input and validation of vector data Board on Geographic Names processes Input and validation of gazetteer data Operational products and services Business as Usual ? Exceptions Once a feature is conflated with GNIS, Only Structure Point Spatials can be modified in GNIS forms All others go thru Vector Applications As of end of FY 2009 Tools and Application in place Acquire and modify Vector and Names representations Data Management of those edits in place to process and deliver
