Monitoring of Spatial Data Infraestructures

SDI monitoring and evaluation is increasingly attracting the attention of both public sector bureaucrats seeking justification for providing public sources to SDI and SDI practitioners requiring a measure of success of their SDI strategy. In recent years, a shift from an intuitive to more rational SDI assessments can be observed. SDI monitoring and evaluation is becoming operational and is already part of some SDI implementations and practices. Based on an analysis of the operational monitoring systems of the Dutch national SDI (GIDEON), the European SDI (INSPIRE) and the Catalan SDI (IDEC). We describe, analyze and compare comprehensively the design and application of operational SDI monitoring systems and identify common issues to be taken into account for monitoring of SDIs. This can support further improvement of evaluation practices and operational setups of SDI monitoring systems

The economic value of the Dutch geo-information sector

Defining the geo-information sector and estimating its economic value on a national level is difficult and standard methodologies are not available. The aim of this paper is to clearly define the geo-information sector and to measure its economic value in terms of turnover, employment, activities and the market. The results of the survey in the Netherlands estimate the economic value of the Dutch geo-information sector at € 1.4 billion, 0.25% of the national GDP. Furthermore, the results show that the Dutch geo-information sector is a fast developing sector with high potential. The authors conclude that the definition used and the developed survey methodology provides a good basis for measuring the value of the national geo-information sector. They suggest carrying out comparable studies in other countries in order to increase awareness of the geo-information sector as a sector of economic importance and to stimulate further development and innovatio

A characterization of Volunteered Geographic Information

This paper characterizes the Volunteered Geographic Information (VGI) phenomenon and explores comprehensively its relation with SDI. The SDI component view is used as common framework for describing the main characteristics of VGI and as framework for exploring VGI and SDI relation. Openstreetmap, Wikiloc, 360.org, Wikimapia and Eye on earth are evaluated to indentify general characteristics of VGI initiatives and discuss differences and similarities between VGI and SDI. Despite differences between VGI and SDI similarities can be identified. Characteristics of all SDI components have been identified in the VGI case studies. Despite differences between VGI and SDI similarities can be identified. Characteristics of all SDI components have been identified in the VGI case studies

An assessment view to evaluate whether Spatial Data Infrastructures meet their goals

The motives for constructing Spatial Data Infrastructures (SDIs) are often based on their anticipated benefits for society, economy, and environment. According to those widely articulated but rarely proven benefits, SDI coordinators have been defining more specific objectives to be achieved by their SDIs. However, there is a limited number of assessment approaches that are able to demonstrate whether SDIs indeed realize the intended goals. In this article we develop, apply and evaluate an assessment view for evaluating the extent to which SDIs realize their goals. The assessment view has been developed stepwise using the Multi-view SDI assessment framework as a guideline. The application of the proposed view in the Dutch SDI demonstrates its potential. In addition, the evaluation of the proposed view by the potential users confirms to a certain extent its usability. The results also show that the ease of determining assessment indicators depends on the precision with which the SDI goals are formulated. (C) 2010 Elsevier Ltd. All rights reserved.status: publishe
