Strategic and Acupunctural GIS Implementation within Community-Oriented Organizations: Evidence-Based Insights from a South African Participatory Action Research for Informal Settlement Upgrading / Jennifer Barella in Cartographica, vol 55 n° 4 (Winter 2020)  

Public [article]  inCartographica > vol 55 n° 4 (Winter 2020) . - pp 266 - 280 Titre : Strategic and Acupunctural GIS Implementation within Community-Oriented Organizations: Evidence-Based Insights from a South African Participatory Action Research for Informal Settlement Upgrading Type de document : Article/Communication Auteurs : Jennifer Barella, Auteur Année de publication : 2020 Article en page(s) : pp 266 - 280 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Systèmes d'information géographique [Termes IGN] Cape Town [Termes IGN] organisation non gouvernementale [Termes IGN] outil d'aide à la décision [Termes IGN] recensement [Termes IGN] SIG participatif Résumé : (Auteur) This article brings evidence-based insights to support the importance of considering contextual elements when analyzing modalities of GIS implementation within NGOs and community-based organizations. I discuss challenges and unforeseen insights of GIS implementation within an advocacy NGO that supports community claims in an informal settlement of Cape Town’s metropolitan area. Through the lens of empirical data, limitations of the GIS implementation models framework are highlighted. GIS implementation will appear to be “acupunctural” and highly strategic and will unveil the use of GIS-based solutions as relational leverage. Finally, I discuss directions for further scientific research on GIS implementation within NGOs and community-based organizations.

CityJSON in QGIS: Development of an open‐source plugin / Stelios Vitalis in Transactions in GIS, Vol 24 n° 5 (October 2020)  

Public [article]  inTransactions in GIS > Vol 24 n° 5 (October 2020) . - pp 1147-1164 Titre : CityJSON in QGIS: Development of an open‐source plugin Type de document : Article/Communication Auteurs : Stelios Vitalis, Auteur ; Ken Arroyo Ohori, Auteur ; Jantien Stoter, Auteur Année de publication : 2020 Article en page(s) : pp 1147-1164 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Systèmes d'information géographique [Termes IGN] CityGML [Termes IGN] édition en libre accès [Termes IGN] format JSON [Termes IGN] implémentation (informatique) [Termes IGN] modèle 3D de l'espace urbain [Termes IGN] module d'extension [Termes IGN] QGIS [Termes IGN] visualisation 3D Résumé : (Auteur) When QGIS 3.0 was released in 2018, it added support for 3D visualisation. At the same time, CityJSON has been developing as an easy‐to‐use JavaScript Object Notation (JSON) encoding for 3D city models using the CityGML 2.0 data model. Together, this opened the possibility to support semantic 3D city models in the popular open‐source GIS software for the first time. In order to add support for 3D city models in QGIS, we have developed a plugin that enables CityJSON datasets to be loaded. The plugin parses a CityJSON file and analyses its tree structure to identify all city objects. Then, the geometry and attributes of every city object are transformed into QGIS features and divided into layers according to user preferences. CityJSON parsing was proven to be straightforward and consistent when tested against several open datasets. One of the biggest challenges we faced, though, was mapping CityJSON’s hierarchical data structure to the relational model of QGIS. We undertook this issue by providing various methods on how geometries from the model are loaded as QGIS features. We intend to use the plugin for educational purposes in our university and we believe it can be proven a worthy tool for researchers and practitioners.

Follow the road: historical GIS for evaluating the development of routes in the Negev region during the twentieth century / Motti Zohar in Cartography and Geographic Information Science, vol 47 n° 6 (October 2020)  

Public [article]  inCartography and Geographic Information Science > vol 47 n° 6 (October 2020) . - pp 532 - 546 Titre : Follow the road: historical GIS for evaluating the development of routes in the Negev region during the twentieth century Type de document : Article/Communication Auteurs : Motti Zohar, Auteur Année de publication : 2020 Article en page(s) : pp 532 - 546 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Systèmes d'information géographique [Termes IGN] carte militaire [Termes IGN] cartographie historique [Termes IGN] Palestine [Termes IGN] point d'appui [Termes IGN] point d'intérêt [Termes IGN] réseau routier [Termes IGN] Sinai [Termes IGN] transformation polynomiale [Termes IGN] vingtième siècle Résumé : (auteur) At the beginning of the twentieth century, a British mapping team led by Captain S. F. Newcombe surveyed and mapped the Negev region, Sinai, and western Jordan. The map was mainly produced for military use. Consequently, it included a network of branched routes, water supplies and facilities, and topographic contours. This study used this map to examine the development of routes in the Negev region between the beginning of and until the end of the twentieth century. First, the individual sheets comprising the study area were pieced together and the accuracy of the map was evaluated. The accuracy found on the Newcombe map was 0.76 mm on the map scale, equivalent to 100.3 m. Route development during the twentieth century was then evaluated by comparing the routes digitized from the Newcombe map to digitized routes on a late twentieth-century map. The results do not reveal tremendous changes in path, shape, or number of routes. Instead, they merely indicate the natural development in their quality. This Historical GIS-based approach provided a useful technique for analyzing and comparing the line segments extracted from historical and modern maps. The implemented approach may also serve other geographical or historical studies aiming to examine the development of branched networks throughout history.

It was ensured that the number of points in each TIN was approximately equal to the number calculated by Töpfer’s formula, and that the vertical error of each TIN was less than the error calculated by Koppe’s formula. According to the results, (1) both methods are quality prioritized, (2) IPE is more sensitive to local surface changes, (3) important triangle edges determined by IPE make a significant contribution to the TIN, (4) some of the points selected by IPE are more important points than that of VIP, and (5) IPE-based TINs are more structural fidelity than VIP-based TINs.

A context sensitive approach to anonymizing public participation GIS data: From development to the assessment of anonymization effects on data quality / Kamyar Hasanzadeh in Computers, Environment and Urban Systems, vol 83 (September 2020)  

Public [article]  inComputers, Environment and Urban Systems > vol 83 (September 2020) . - n° 101513 Titre : A context sensitive approach to anonymizing public participation GIS data: From development to the assessment of anonymization effects on data quality Type de document : Article/Communication Auteurs : Kamyar Hasanzadeh, Auteur ; Anna Kajosaari, Auteur ; Dan Häggman, Auteur ; Marketta Kyttä, Auteur Année de publication : 2020 Article en page(s) : n° 101513 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Systèmes d'information géographique [Termes IGN] analyse spatiale [Termes IGN] anonymisation [Termes IGN] approche participative [Termes IGN] collecte de données [Termes IGN] données ouvertes [Termes IGN] protection de la vie privée [Termes IGN] qualité des données [Termes IGN] SIG participatif [Termes IGN] système d'information géographique Résumé : (auteur) Use of Public Participation Geographic Information System (PPGIS) for data collection has been significantly growing over the past few years in different areas of research and practice. With the growing amount of data, there is little doubt that a potentially wider community can benefit from open access to them. Additionally, open data add to the transparency of research and can be considered as an essential feature of science. However, data anonymization is a complex task and the unique characteristics of PPGIS add to this complexity. PPGIS data often include personal spatial and non-spatial information, which essentially require different approaches for anonymization. In this study, we first identify different privacy concerns and then develop a PPGIS data anonymization strategy to overcome them for an open PPGIS data. Specifically, this article introduces a context-sensitive spatial anonymization method to protect individual home locations while maintaining their spatial resolution for mapping purposes. Furthermore, this study empirically evaluates the effects of data anonymization on PPGIS data quality. The results indicate that a satisfactory level of anonymization can be reached using this approach. Moreover, the assessment results indicate that the environmental and home range measurements as well as their intercorrelations are not significantly biased by the anonymization. However, necessary analytical measures such as use of larger spatial units is recommendable when anonymized data is used. In this study, European data protection regulations were used as the legal guidelines. However, adaptation of methods employed in this study may be also relevant to other countries where comparable regulations exist. Although specifically targeted at PPGIS data, what is discussed in this paper can be applicable to other similar spatial datasets as well.
