ESRI Lays Foundation for the International Cadastre Data Model 05.02.2003
ESRI announces a development initiative focused on creating an ArcGIS Cadastre Data Model template based on the Cadastre 2014 concepts of the International Federation of Surveyors (FIG). Cadastre 2014 was originally proposed in 1994 as a template for the development of a modern cadastre system based on geographic information system (GIS) technology and presents a vision for cadastral agency operations in the year 2014.
As with other data model initiatives, ESRI has reached out to industry experts for their input and advice. Together with FIG and the International Institute for Geo-Information Science and Earth Observation (ITC), ESRI recently cohosted an international cadastre data model workshop at the ITC headquarters in Enschede, the Netherlands. More than 30 cadastre data modeling experts from around the world gathered to share their expertise and project experience to help define the core data model requirements. The goal of the workshop was to refine the initial 2014 cadastral data model so it could be used to implement core requirements, which include the management of multiple property rights and restrictions by cadastre agencies.
Led by Steve GrisÂ¿rom ESRI and Christiaan Lemmen from ITC, the workshop was opened by Professeur Paul van der Molen of ITC, who shared his extensive international experience with various land management systems. This was followed by selected presentations from attendees, who outlined the many issues involved in implementing cadastre systems in their organizations.
Specialist working group meetings on property rights, survey/topography, and land registry and philosophy were conducted and, after lengthy discussions, reported back to the general meeting to consider specific issues and recommendations.
It is anticipated that within a few weeks the preliminary version of ESRI's ArcGIS Cadastre 2014 Data Model will be released on the ESRI Data Model Web page (http://support.esri.com/datamodels), joining the existing Land Parcel Data Model and others. The ArcGIS Cadastre 2014 Data Model is a part of ESRI's ongoing effort to provide its users and the broader GIS community with practical, open, standards-based templates for industry-specific data models that are intended to facilitate the successful implementation of GIS. A key design goal of the data model efforts is that each data model must be open, multipurpose, and standards based. ESRI builds each design on appropriate implementations of the Open GIS Consortium (OGC) Simple Features Specification in which the spatial data is managed in database management system tables. The land records and cadastre community is encouraged to further enhance the ArcGIS Cadastre 2014 Data Model by leaving feedback on the ESRI Data Model Web page.
