Their subjective nature, however, and the resulting difficulties in collecting data, means that in many countries there are no officially defined neighbourhoods either in terms of names or boundaries. This has implications not only for policy but also business and social decisions as a whole. With the absence of neighbourhood boundaries many studies resort to using standard administrative units as proxies. Such administrative geographies, however, often have a poor fit with those perceived by residents. Our approach detects these important social boundaries by automatically mining the Web en masse for passively declared neighbourhood data within postal addresses. Focusing on the United Kingdom (UK), this research demonstrates the feasibility of automated extraction of urban neighbourhood names and their subsequent mapping as vague entities. Importantly, and unlike previous work, our process does not require any neighbourhood names to be established a priori.

Crossing boundaries: mapping spatial dynamics of urban phenomena at micro scale to support urban management in the Amsterdam urban region / Els Veldhuizen in Belgeo, vol 2016 n° 2 (2016-2)  

Public [article]  inBelgeo > vol 2016 n° 2 (2016-2) Titre : Crossing boundaries: mapping spatial dynamics of urban phenomena at micro scale to support urban management in the Amsterdam urban region Type de document : Article/Communication Auteurs : Els Veldhuizen, Auteur ; Karin Pfeffer, Auteur Année de publication : 2016 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] accessibilité [Termes IGN] Amsterdam (Pays-Bas) [Termes IGN] cartographie urbaine [Termes IGN] distribution spatiale [Termes IGN] données spatiotemporelles [Termes IGN] dynamique spatiale [Termes IGN] gestion urbaine [Termes IGN] limite indéterminée [Termes IGN] WebSIG [Vedettes matières IGN] Géovisualisation Résumé : (auteur) Maps are widely used to provide urban managers with information on critical urban issues such as deprivation, unemployment, and segregation. Although administrative boundaries have always played an important role in map making, they are not meaningful for revealing the spatial dynamics of urban phenomena that vary within wards, cross ward boundaries and do not necessarily stop at the city boundary. Recently, very detailed (spatial) data have become available providing opportunities for new types of urban mapping. To process these data into meaningful maps, three aspects are important. First, information on maps should be produced at a spatial scale that is relevant for a particular urban phenomenon. Second, to reveal and monitor urban dynamics, maps of a phenomenon at different moments in time are needed. Finally, to accommodate access to these maps for potential users without (much) expertise in mapping, they should be provided through an easy to use tool. The Regional Monitor Amsterdam (RMA), an online GIS application, deals with these aspects. The purposes of this paper are to explain the mapping methodology adopted in the RMA and to illustrate the usefulness of the tool in urban management. This methodology goes beyond administrative mapping areas with fixed boundaries by introducing ‘data-driven dynamic geographies’. We argue that this methodology produces relevant information by recognizing the scale at which urban phenomena occur. The monitoring tool assists in answering policy questions by easy access to relevant maps for different moments in time.

Using a geographic information system to resolve a riparian boundary / Josephina Campbell in SaLIS Surveying and land information science, vol 72 n° 4 (December 2012)

Public [article]  inSaLIS Surveying and land information science > vol 72 n° 4 (December 2012) . - pp 195 - 202 Titre : Using a geographic information system to resolve a riparian boundary Type de document : Article/Communication Auteurs : Josephina Campbell, Auteur ; Brent Corning, Auteur ; Seth Frazier, Auteur Année de publication : 2012 Article en page(s) : pp 195 - 202 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Applications SIG [Termes IGN] intégration de données [Termes IGN] limite cadastrale [Termes IGN] limite indéterminée [Termes IGN] rivière [Termes IGN] système d'information géographique Résumé : (Auteur)Geographic Information System (GIS) technology is rapidly evolving into a valuable tool for land surveying professionals. GIS surveying applications include land record databases, land use planning, and the compilation of historical mapping and aerial photography. A professional surveying project can include determining the location of a riparian or littoral boundary. This project shows how a professional land surveyor can utilize GIS software to solve a riparian boundary. The case study for this paper is the Lost River in Klamath County, Oregon. This research project includes historical survey data, maps, and aerial photography. The historical data are combined with current global navigation satellite system (GNSS) survey data and LiDAR imagery to solve the riparian boundary. Figure 1 shows the area of the case study.

Mining boundary effects in areally referenced spatial data using the Bayesian information criterion / Sudipto Banerjee in Geoinformatica, vol 15 n° 3 (July 2011)

Subsequent interest often resides in the formal identification of ‘boundaries’ on the map. Here boundaries refer to ‘difference boundaries’, representing significant differences between adjacent regions. Recently, Lu and Carlin (Geogr Anal 37:265–285, 2005) discussed a Bayesian framework to carry out edge detection employing a spatial hierarchical model that is estimated using Markov chain Monte Carlo (MCMC) methods. Here we offer an alternative that avoids MCMC and is easier to implement. Our approach resembles a model comparison problem where the models correspond to different underlying edge configurations across which we wish to smooth (or not). We incorporate these edge configurations in spatially autoregressive models and demonstrate how the Bayesian Information Criteria (BIC) can be used to detect difference boundaries in the map. We illustrate our methods with a Minnesota Pneumonia and Influenza Hospitalization dataset to elicit boundaries detected from the different models.
