Geoweb, Neogeography, and VGI: New Challenges for Geomatics Sciences and Engineering Stéphane ROCHE, Canada SUMMARY An important democratization process characterizes Geospatial technologies. Web mapping and virtual globes, GeoWeb, GPS navigation, Location Based Services - LBS or geocaching are concrete examples of this democratization process. Geospatial technologies are accessible everywhere, every time, and by everybody. Even if such a process seems to impact GI Sciences, very little is known about its characteristics and mechanisms. This process is embedded into the exponential development of the Web 2.0., which is a more opened Web, based on sharing, peering and crowdsourcing, in which the location component plays a dominating part - GeoWeb. In this context, new forms of geospatial information production appear, illustrated by web service like Wikimapia or OpenStreetMap for example. Such a "User-driven generated content "initiative", qualified by Mike Goodchild as "Volunteered Geographic Information - VGI", are more generally linked to the new trend called "Neogeography". Our presentation aims at providing an overview of the concept of neogeography from a geomatics sciences perspective, by providing a critical analysis of the geospatial technology democratization process. We provide an analysis of the most popular forms of neogeoraphy, through a series of case studies (Point Of Interest – POI, creation e- community, VGI, geoblog or wikicarto). This presentation finally highlights to what extent all these initiatives challenge geomatics sciences and engineering, from a technological and informational perspective as well as from a professional certification perspective.

Geo-Text Data and Data-Driven Geospatial Semantics
Geo-Text Data and Data-Driven Geospatial Semantics Yingjie Hu GSDA Lab, Department of Geography, University of Tennessee, Knoxville, TN, 37996, USA Abstract Many datasets nowadays contain links between geographic locations and natural language texts. These links can be geotags, such as geotagged tweets or geotagged Wikipedia pages, in which location coordinates are explicitly attached to texts. These links can also be place mentions, such as those in news articles, travel blogs, or historical archives, in which texts are implicitly connected to the mentioned places. This kind of data is referred to as geo- text data. The availability of large amounts of geo-text data brings both challenges and opportunities. On the one hand, it is challenging to automatically process this kind of data due to the unstructured texts and the complex spatial footprints of some places. On the other hand, geo-text data offers unique research opportunities through the rich information contained in texts and the special links between texts and geography. As a result, geo-text data facilitates various studies especially those in data-driven geospatial semantics. This paper discusses geo-text data and related concepts. With a focus on data-driven research, this paper systematically reviews a large number of studies that have discovered multiple types of knowledge from geo-text data. Based on the literature review, a generalized workflow is extracted and key challenges for future work are discussed. Keywords: geo-text data, spatial analysis, natural language processing, spatial and textual data analysis, data-driven geospatial semantics, spatial data science. 1. Introduction Recent years have witnessed an unprecedented increase in the volume, variety, and veloc- ity of data from different sources (Miller and Goodchild, 2015).

Using Wordpress to Manage Geocontent and Promote Regional Food Products
Farm2.0: Using Wordpress to Manage Geocontent and Promote Regional Food Products Amenity Applewhite Farm2.0: Using Wordpress to Manage Geocontent and Promote Regional Food Products Dissertation supervised by Ricardo Quirós PhD Dept. Lenguajes y Sistemas Informaticos Universitat Jaume I, Castellón, Spain Co-supervised by Werner Kuhn, PhD Institute for Geoinformatics Westfälische Wilhelms-Universität, Münster, Germany Miguel Neto, PhD Instituto Superior de Estatística e Gestão da Informação Universidade Nova de Lisboa, Lisbon, Portugal March 2009 Farm2.0: Using Wordpress to Manage Geocontent and Promote Regional Food Products Abstract Recent innovations in geospatial technology have dramatically increased the utility and ubiquity of cartographic interfaces and spatially-referenced content on the web. Capitalizing on these developments, the Farm2.0 system demonstrates an approach to manage user-generated geocontent pertaining to European protected designation of origin (PDO) food products. Wordpress, a popular open-source publishing platform, supplies the framework for a geographic content management system, or GeoCMS, to promote PDO products in the Spanish province of Valencia. The Wordpress platform is modified through a suite of plug-ins and customizations to create an extensible application that could be easily deployed in other regions and administrated cooperatively by distributed regulatory councils. Content, either regional recipes or map locations for vendors and farms, is available for syndication as a GeoRSS feed and aggregated with outside feeds in a dynamic web map.

Preserving Geospatial Data
Technology Watch Report Preserving Geospatial Data Guy McGarva EDINA, University of Edinburgh Steve Morris North Carolina State University (NCSU) Greg Janée University of California, Santa Barbara (UCSB) DPC Technology Watch Series Report 09-01 May 2009 © 2009 1 Executive Summary: Geospatial data are becoming an increasingly important component in decision making processes and planning efforts across a broad range of industries and information sectors. The amount and variety of data is rapidly increasing and, while much of this data is at risk of being lost or becoming unusable, there is a growing recognition of the importance of being able to access historical geospatial data, now and in the future, in order to be able to examine social, environmental and economic processes and changes that occur over time. The geospatial domain is characterized by a broad range of information types, including geographic information systems data, remote sensing imagery, three- dimensional representations and other location-based information. The scope of this report is limited to two-dimensional geospatial data and data that would typically be considered comparable to paper maps or charts including vector data, raster data and spatial databases. There are a number of significant preservation issues that relate specifically to geospatial data, including: the complexity and variety of data formats and structures; the abundance of content that exists in proprietary formats; the need to maintain the technical and social contexts in which the data exists; and the growing importance of web services and dynamic (and ephemeral) data. Standards for geospatial metadata have been defined at both the national and international levels, yet metadata often becomes dissociated from the data, or is incorrect, non-standard in nature, or not created in the first place.

Almost everyone in the world uses mapping information, whether or not one realizes it. Almost every mobile phone now has location services and every event and object on the earth has a location. The use of this geospatial location data has expanded rapidly, thanks to the development of the Internet. Huge volumes of geospatial data are available and daily being captured online, and are used in web applications and maps for viewing, analysis, modeling and simulation. This paper reviews the developments of web mapping from the ﬁrst static online map images to the current highly interactive, multi-sourced web mapping services that have been increasingly moved to cloud computing platforms. The whole environment of web mapping captures the integration and interaction between three components found online, namely, geospatial information, people and functionality. In this paper, the trends and interactions among these components are identiﬁed and reviewed in relation to the technology developments.

Volunteered and Crowdsourced Geographic Information: the Openstreetmap Project
JOURNAL OF SPATIAL INFORMATION SCIENCE Number 20 (2020), pp. 65–70 doi:10.5311/JOSIS.2020.20.659 INVITED ARTICLE Volunteered and crowdsourced geographic information: the OpenStreetMap project Michela Bertolotto1, Gavin McArdle1, and Bianca Schoen-Phelan2 1School of Computer Science, University College Dublin 2School of Computer Science, Technological University Dublin Received: February 28, 2020; accepted: May 12, 2020 Abstract: Advancements in technology over the last two decades have changed how spa- tial data are created and used. In particular, in the last decade, volunteered geographic information (VGI), i.e., the crowdsourcing of geographic information, has revolutionized the spatial domain by shifting the map-making process from the hands of experts to those of any willing contributor. Started in 2004, OpenStreetMap (OSM) is the pinnacle of VGI due to the large number of volunteers involved and the volume of spatial data generated. While the original objective of OSM was to create a free map of the world, its uses have shown how the potential of such an initiative goes well beyond map-making: ranging from projects such as the Humanitarian OpenStreetMap (HOT) project, that understands itself as a bridge between the OSM community and humanitarian responders, to collaborative projects such as Mapillary, where citizens take street-level images and the system aims to automate mapping. A common trend among these projects using OSM is the fact that the community dynamic tends to create spin-off projects. Currently, we see a drive towards projects that support sustainability goals using OSM. We discuss some such applications and highlight challenges posed by this new paradigm.

How Good Is Openstreetmap Information
Haklay, M., 2008, Please note that this is an early version of this article, and that the definitive, peer- reviewed and edited version of this article is published in Environment and Planning B: Planning and Design. Please refer to the publication website for the definitive version. How good is Volunteered Geographical Information? A comparative study of OpenStreetMap and Ordnance Survey datasets Abstract Within the framework of Web Mapping 2.0 applications, the most striking example of a geographical application is the OpenStreetMap project. OpenStreetMap aims to create a free digital map of the world and is implemented through the engagement of participants in a mode similar to software development in Open Source projects. The information is collected by many participants, collated on a central database and distributed in multiple digital formats through the World Wide Web (Web). This type of information was termed ‘Volunteered Geographical Information’ (VGI) by Mike Goodchild (2007). However, to date there has been no systematic analysis of the quality of VGI. This paper aims to fill this gap by analysing OpenStreetMap information. The examination starts with the characteristics of OpenStreetMap contributors, followed by analysis of its quality through a comparison with Ordnance Survey datasets. The analysis focuses on London and England, since OpenStreetMap started in London in August 2004 and therefore the study of these geographies provides the best understanding of the achievements and difficulties of VGI. The analysis shows that OpenStreetMap information can be fairly accurate: on average within about 6 metres of the position recorded by the Ordnance Survey, and with approximately 80% overlap of motorway objects between the two datasets.

Expanding Library GIS Instruction to Web Mapping in the Age of Neogeography
Final version published as: Zhang, S. (2021). Expanding Library GIS Instruction to Web Mapping in the Age of Neogeography. Journal of Map & Geography Libraries, 1–19. https://doi.org/10.1080/15420353.2021.1935399. Expanding Library GIS Instruction to Web Mapping in the Age of Neogeography Sarah Zhang, Simon Fraser University Library Abstract The past two decades witnessed the flourishing of GeoWeb, a web infused with geospatial services and applications, which has given rise to a trend that non‐experts are increasingly involved in creating digital maps, collecting spatial data, and developing mapping mashups or applications, known as neogeography. In light of that, the general public and researchers/students in higher education institutions are becoming increasingly interested in these technologies. However, a gap exists between the GIS educational programs offered by public/academic libraries in Canada and the fast developing web mapping technologies as well as the shifting needs of users. This paper describes two web mapping workshop initiatives at a public library and an academic library, arguing web mapping technologies provides new opportunities to adapt ACRL Information Literacy to GIS education, and advocating academic and public libraries’ involvement in web mapping instruction in the age of neogeography. Introduction Revolutionary technologies in the past decade or so have drastically transformed the landscape of maps and mapping‐ digital maps have dramatically outpaced print maps, interactive web maps or apps have become a ubiquitous part of everyone’s daily life. Higher education institutions, however, have only started to respond to this shift by offering web mapping programs and courses. While distance education programs in web mapping have notably jumped in to fill the gap, with the most prominent examples being the Pennsylvania State University and the University of Kentucky, the cartography and GIS programs in North America which offer courses in web mapping have not become the mainstream (Sack 2018).

Received: 10 December 2013; in revised form: 10 January 2014 / Accepted: 13 January 2014 / Published: 27 January 2014 Abstract: User-generated content (UGC) platforms on the Internet have experienced a steep increase in data contributions in recent years. The ubiquitous usage of location-enabled devices, such as smartphones, allows contributors to share their geographic information on a number of selected online portals. The collected information is oftentimes referred to as volunteered geographic information (VGI). One of the most utilized, analyzed and cited VGI-platforms, with an increasing popularity over the past few years, is OpenStreetMap (OSM), whose main goal it is to create a freely available geographic database of the world. This paper presents a comprehensive overview of the latest developments in VGI research, focusing on its collaboratively collected geodata and corresponding contributor patterns. Additionally, trends in the realm of OSM research are discussed, highlighting which aspects need to be investigated more closely in the near future.

A Protocol and Prototype Application to Find Maps
MAPSEARCH: A PROTOCOL AND PROTOTYPE APPLICATION TO FIND MAPS by JUDITH GELERNTER A Dissertation submitted to the Graduate School-New Brunswick Rutgers, The State University of New Jersey In partial fulfillment of the requirements for the degree of Doctor of Philosophy Graduate Program in Communication, Information and Library Studies Written under the direction of Professor Michael E. Lesk and approved by ________________________ ________________________ ________________________ ________________________ New Brunswick, New Jersey May 2008 © 2008 Judith Gelernter ALL RIGHTS RESERVED ABSTRACT OF THE DISSERTATION MAPSEARCH: A Protocol and Prototype Application to Find Maps By Judith Gelernter Dissertation Director: Professor Michael Lesk Even geographers need ways to find what they need among the thousands of maps buried in map libraries and in journal articles. It is not enough to provide search by region and keyword. Studies of queries show that people often want to look for maps showing a certain location at a certain time period or with a subject theme. The difficulties in finding such maps are several. Maps in physical and digital collections often are organized by region. Multi-dimensional manual indexing is time-consuming and so many maps are not indexed. Further, maps in non-geographical publications are indexed rarely, making them essentially invisible. In an attempt to solve actual problems, this dissertation research automatically indexes maps in published documents so that they become visible to searchers. The MapSearch prototype aggregates journal components to allow finer-grained searching of article content. MapSearch allows search by region, time, or theme as well as by keyword (http://scilsresx.rutgers.edu/~gelern/maps/). Automatic classification of maps is a multi-step process.

Significance of Collaborative Cartography
ARTICLE Significance of Collaborative Cartography It is well recognised that mapping has perhaps changed more profoundly in recent years than in any previous era. In the past map production was reserved for professional cartographers and dissemination was radial: users were amateurs who consumed professional products. The revolutions in digital cartography, initiated in the 1980s, did little to alter expert control over mapping, and GIS if anything exacerbated the power of the producer. Now, however, websites such as Google Earth offer everyone the chance to produce their own individual maps, in many cases without the need of any professional qualification. Never before has such democratisation been as widespread. So many users today are brought together via the internet that producers and consumers are no longer distinguishable. Ambivalence These developments evoke ambivalent attitudes: some critical writers have argued they spell the end of traditional cartography. There is an increasing need for dynamic, and particularly interactive, maps, and web 2.0 offers a suitable platform for these new approaches to the acquisition, assembly and publication of geographic information. Others embrace a new era of map production with undreamed-of possibilities offered by the bi-directional collaboration that characterises the new mapping worlds of web 2.0. New terminologies are emerging to reflect this changing conceptual field: in contrast to the old cartography, there is now ‘neogeography', embracing the integrative power of ubiquitous computing in which geography brings together the formerly separate. Yet others cast these developments as volunteered geographic information (VGI), stressing the potential of locally sourced or volunteered information. Control To date, most academic cartographic research has focused on controlling the syntactical dimension of communication and trying to provide better maps by exploring useful semantic aspects.
