Cadastral Framework Project
June 15, 1999
Since the last Cadastral Framework Project meeting in November, much has happened on the Cadastral Framework Project. The final draft of the Partnership Agreement is under review, and has been sent to the department supervisor for DNR signature. The DNR has completed its conversion of public land survey, ownership, administration, management, and corner GIS layers to the cadastral database. The integration pilot has been developing business procedures, standards, and integration methods. Integration is being tested in a development environment. The Washington Interagency Committee for Outdoor Recreation has been working to develop support for a proposal to the legislature to support the Cadastral Framework as a means of keeping the public lands inventory up to date. The framework projects have been meeting to coordinate the framework theme implementations. In the most recent event, the Washington Cadastral Framework Project has been invited by the National States Geographic Information Council to join the Parcel Consortium of an ESRI project sponsored by the U.S. Bureau of Land Management and U.S. Forest Service which will develop cadastral object classes and object editing software to be implemented as part of ARC 8.1.
The integration pilot partners met 02/03/99, 03/03/99, 04/07/99, and 05/05/99, to address the technical implementation of integration standards and processes. Another integration meeting is scheduled for 07/14/99 to finalize the deliverable products. Participants in the integration pilot are Snohomish County, US Bureau of Land Management, Longview Fibre, ESRI, DNR, and Clallam County. Minutes for the meetings and revisions for the business processes and roles have been distributed.
The integration pilot is attempting to minimize the work load on the data integrator and data providers. Partners discussed several possible procedures for integrating data in the pilot. Partners are providing updated data sets for integration development and testing. Partners determined that the scope of the integration pilot is limited to Legal Area Descriptions, Boundaries, and Corners. BLM is developing the PLS subdivision of sixteenth sections and government lots, and assigning GCDB codes to corners in east Snohomish County. BLM's revisions will be integrated into the framework database. A cadastral data transfer standard has been developed to allow partners to extract data from their data sets and integrate the data into the framework database. Partners have reviewed the data transfer standard several times. DNR is developing AML programs which will create transfer standard tables, format partner data into the transfer standard, and extract ASCII attribute and shape files for integration with the framework database. These AML programs could be used as examples by additional partners for developing procedures to integrate their data.
IAC has held meetings of the Public Lands Inventory Project Data Reporting Committee on 01/12/99, 02/24/99, and 04/21/99, to discuss continuing support and maintenance of public lands records with respect to their mandate from the legislature to provide options for future public lands inventory updates. Some organizations on the Data Reporting Committee has expressed an interest in providing additional local government requirements to the project at the next opportunity for revision.
Representatives of the framework Transportation, Hydrography, and Cadastral projects have met on 01/26/99, 02/18/99, 03/31/99, and 04/29/99, to review requirements of theme integration and coordinate development. The Cadastral Framework Project has expressed interest in Hydrography features, and Transportation routes and addressing. Hydrography and Transportation projects are interested in having the Cadastral Framework provide point coordinates of significant locations.
The NILS project will rely on the Washington Cadastral Framework Project to provide representation of the Washington Framework partners, representation of Pacific Northwest states, input on changes that should be made to the Cadastral Data Content Standard, implementation of the cadastral object classes, and development of tools to edit those objects within ARC 8.1. The Washington Cadastral Framework Project should continue as planned with minimal delay in implementation. Participation in the NILS project provides an opportunity to promote the standards which the Washington partners have developed at a national level. The Washington partners can expect the NILS project to develop similar extensions to the FGDC standards which the Washington partners have developed. We can expect some differences in content, naming, and formatting, and to make compromises on some of these differences. But, we will end up with a national standard which will make cadastral communications and analysis possible between a wider set of organizations. The NILS project manager would like to have one or more representatives of the Washington Cadastral Framework Project attend between four and eight sessions from June through October. Project partners have agreed upon DNR participating in several meetings and then reassessing the value of continuing.
The remaining tasks for the project are to establish the check-out/in procedures, integrate data using standard procedures, develop database backup/recovery procedures, and define a plan for continuing to support the cadastral framework database and its maintenance. If time and funding permit, then notification procedures appear to be the next priority. As the FGDC supported development project draws to a close at the end of August, the transition to a supported application system must be made. The development project is just a first step. The integration of cadastral data will go on and noticeable improvements in data quality, coverage, and integration tools will be made.
