"Addresses all aspects of developing and using geographic information systems (GIS) within an organization. Coverage includes the role of the GIS professional, how geographic information fits into broader management information systems, the use of GIS in strategic planning, and ways to navigate the organizational processes that support or inhibit the success of GIS implementation"--Publisher description

Assessment of geographic information infrastructures (or spatial data infrastructures) is increasingly attracting the attention of researchers in the Geographic information (GI) domain. Especially the assessment of value added GI appears to be complex. By applying the concept of value chain analysis to GI, this paper provides a research framework for unambiguously assessing GI value adding. The paper details the enhancing process that must be employed to turn raw geographic information into new services and products regardless of the organisation performing the enhancement. Not only the differences in technical characteristics of data sets are identified, also the roles in a value chain of government organisations and commercial organisations were explored. The framework is applied to two types of GI in the United States and Europe. The presented research shows that the framework allows for true comparison of GI enhancement in different jurisdictions. This should result in better understanding of the level of GI enhancement in a specific jurisdiction and accordingly in effective decisions stimulating GI enhancement, geographic information infrastructures and information societies. ; Built Environment ; OTB Research Institute for the Built Environment

During the past few years much effort has been put into developing community-based methods to capture and analyze a large amount of data in a systematic manner. This new source of geo-referenced data could be very important throughout Africa where crowd sourcing activities or volunteered geographic information (VGI) enhance participation and decision making based on local knowledge. VGI has the potential to be a significant source of information for a variety of applications. It will especially help national mapping authorities to build and update their national geospatial datasets, and improve the availability and currency of the countries fundamental and thematic datasets. Governments therefore need to take proactive measures to develop strategies maximizing on the opportunity in the current technological development. This calls out the need to developing strategic guidance on how to strengthen the communities' participation in data collection. The United Nations Economic commission for Africa developed a document on the best practices and principles for adopting community mapping and VGI in the mapping practices in Africa. An expert group meeting is held to gather experts in the field to discuss on the issues, review best practices and current status on citizen participation in community mapping and to develop a roadmap for the adoption of the technology and agree on the guiding principles. The outcome of the meeting resulted in the framing of guiding principles for community mapping which is published in 2017. This paper therefore provides overview of VGI in Africa and the efforts made to date.

Abstract: What's the relationship between GIS and the political subject? In an effort to address this question, this paper traces the movement from the map to GIS. The map is shown to be the performative utterance of the state, one that supports its national discourse and narrative. GIS, on the other hand, is shown to be a device of neoliberal governmentality, its non-representational economic practices, divided discourse and subjectivities. Despite the seemingly hopeless situation surrounding GIS, however, certain simulation and modelling practices are attempting to construct subjectivities out of economic neoliberalism's fractured narratives. They do this by reading meaning into otherwise mathematical datasets and models. These practices could form a basis for queering GIS. This article is developed through research carried out as part of the Machine Feeling project funded by both Cambridge University's Centre for Research in the Arts, Social Sciences and Humanities (hereafter CRASSH) and Aarhus University. The paper began as a presentation at a workshop based at CRASSH which resulted in a shorted publication entitled Digital Modelling. It was then developed into a larger piece and delivered at Transmediale Festival 2019. Proceedings from both events were then compiled into a special issue of the Transmediale journal ARPJA. The festival, which is due to celebrate its 30th anniversary next year, and journal have wide appeal in digital media circles, especially through social and online media. The special issue includes articles by artists, designers and other academics based in the social sciences and the humanities from Europe, the US and the UK.
