  Citation × Citation Citation Abstract Copy Title: Building and Maintaining a Statewide Transportation Framework Author: Dueker, Kenneth, Bender, Paul Year: 2002 Creating and maintaining up-to-date sharable Geographic Information SystemsTransportation (GIS-T) data is challenging. Many states are working on Transportation Framework efforts to build a complete, consistent, and current transportation data layer in conjunction with the NSDI and Geospatial One-Stop efforts. This paper summarizes an effort that systematically re-examined transportation data sharing issues as part of the development of a Transportation Framework for the State of Washington. Business needs were assessed in terms of spatial and temporal accuracy needs of stakeholders and users of a state-wide Transportation Framework. A conceptual model was developed for a Transportation Framework with emphasis on data flows to update and maintain it and other transportation databases. The paper concludes with a synthesis of issues, including determining the desired robustness of the Transportation Framework and cost allocation principles for possible add-on enhancements.

  Citation × Citation Citation Abstract Copy Title: ORBIT: The Oregon Road base Information Team Draft Summary Report II Author: Bender, Paul, Bosworth, Mark, Dueker, Kenneth Year: 1999 Data sharing among organizations has the potential to 1) decrease long-term costs of obtaining and maintaining data and 2) to facilitate data consistency and accuracy. Consistency includes both completeness and currency, while accuracy includes positional and relative accuracy of transportation features and their attributes, i.e. any data element related to roads or other transportation infrastructure. ORBIT, the Oregon Road Base Information Team, is an ongoing effort to create an accessible and comprehensive GIS transportation base for use by public and private agencies with shared stewardship through stakeholder partnerships and standards. ORBIT is occurring concurrently with an effort at the national level to develop an NSDI Framework Transportation Identification Standard to enhance the development and implementation of principles and procedures for sharing of transportation data Title: ORBIT: The Oregon Road base Information Team Draft Summary Report II Author: Bender, Paul, Bosworth, Mark, Dueker, Kenneth Year: 1999 Data sharing among organizations has the potential to 1) decrease long-term costs of obtaining and maintaining data and 2) to facilitate data consistency and accuracy.

  Citation × Citation Citation Abstract Copy Title: White Paper on Issues and Strategies for Building a State Transportation Framework Author: Dueker, Kenneth, Bender, Paul Year: 2002 The purpose of this white paper is to systematically re-examine transportation data sharing issues that have been discussed at length, but in a manner to foster final decisions and closure. In some cases, choices among alternatives may require more detailed analysis or pilot studies. The development of this document has benefited from discussion at the Interorganizational Resource Information Coordinating Council (IRICC) Roads Committee, which has led to this consensus document. This sixth and final version serves to draw the process to a close and recommends a twofold approach to the development of a Transportation Framework. It also recommends six pilot studies to examine remaining issues in more detail.

  Citation × Citation Citation Abstract Copy Title: Sharing Transportation GIS Data Author: Dueker, Kenneth, Bender, Paul, Zhang, Jihong Year: 2000 Updating and maintaining Geographic Information Systems-Transportation data (GIS-T data) is proving difficult. Different database formats needed to support diverse applications leads to inconsistencies and inaccuracies, and duplication in updating. Dueker and Butler (1998) have proposed an Enterprise GIS-T data model that unbundles the various components of transportation data (network links, cartography, and attributes) to facilitate generating application-specific networks, and which eases updating and maintenance. However, developers of existing application-specific databases that employ integrated data models that bundle the network link with cartography and attributes are reluctant to step back to an intermediate form for managing their data. Consequently, attention is given in this report to the development of a method of incorporating transportation system changes directly to existing application- specific networks.
