Spatial Data Integrability and Interoperability in the Context of SDI

چکیده
The number of multi-sourced heterogeneous spatial datasets continues to grow and the fragmentation of organizational arrangements has caused much technical and non-technical heterogeneity. Spatial Data Infrastructures aim to facilitate spatial data use and sharing, and can be an effective platform to aid in data integration. This paper discusses the technical and non-technical heterogeneities of multisourced spatial data within the holistic framework of Spatial Data Infrastructure. The paper capitalizes on research and case studies undertaken within Australia. The paper also introduces Geo-WebServices as a means of facilitating spatial data integration and interoperability. Geo-WebService can provide a platform to assess the level of integratability and readiness of multi-sourced datasets. The results of this research aim to assist practitioners in developing the necessary technical tools including geo webservices and guidelines for effective data integration.

متن کاملUnderstanding how and why practitioners evaluate SDI performance
Practitioners around the world are building frameworks for spatial data interoperability and cross-agency coordination, referred to as spatial data infrastructure (SDI). In this study, we attempt to understand how and why SDI practitioners ‘on the ground’ are evaluating their ‘own’ efforts in developing such frameworks. For this purpose, we mobilize concepts from ‘control’ evaluation, as well a...
متن کاملFree and Open Source GIS Software for Building a Spatial Data Infrastructure
The implementation of Spatial Data Infrastructures (SDIs) for governments and companies is a task that has gained ample attention in recent years. Different categories of spatial software such as desktop GIS, server GIS, web map servers, spatial database management systems, web map development toolkits, etc., are required to realize the software components of an SDI. We catalogue a (selected) v...
