There are no internationally accepted methodologies to evaluate the efficacy of rural cadastral systems in developing countries. In this study, an evaluation framework was designed from the literature review and used to assess the quality of the rural cadastral system. A mixed research method was applied. Data were secured from the pertinent participants, and descriptive statistics was used to analyze the data. The findings indicated that the framework developed for the quality assessment was found to be an essential tool to evaluate the efficacy of rural cadastral systems. The study identified the strengths, weaknesses, opportunities, and threats of the cadastral systems of the Amhara region, which underpinned the understanding of the spatial, legal, and institutional arrangements and statuses. Further, this study identified sets of indicators and good practices of the system.

A participatory trail web map based on open source technologies / Joshua Gore in International journal of cartography, vol 8 n° 2 (July 2022)  

Public [article]  inInternational journal of cartography > vol 8 n° 2 (July 2022) . - pp 223 - 242 Titre : A participatory trail web map based on open source technologies Type de document : Article/Communication Auteurs : Joshua Gore, Auteur ; Stefan Peters, Auteur ; Delene Weber, Auteur Année de publication : 2022 Article en page(s) : pp 223 - 242 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique web [Termes IGN] approche participative [Termes IGN] Australie méridionale (Australie) [Termes IGN] base de données localisées [Termes IGN] carte interactive [Termes IGN] chemin rural [Termes IGN] données localisées des bénévoles [Termes IGN] données localisées libres [Termes IGN] évaluation des données [Termes IGN] qualité des données [Termes IGN] randonnée [Termes IGN] web mapping Résumé : (auteur) Interactive maps can be an important marketing tool for disseminating information about long distance walking trails and a way to value add to the recreation experience. Providing participatory functionality to maps by allowing users to share new information or refine existing information can greatly enhance user interest and improve the product. This research uses open source front and back end technologies to develop a single page, database driven participatory web map application for the Walk the Yorke Trail in South Australia. The development is based on and assessed through a user-centred design approach. The prototype participatory web map is assessed by cartographic experts, trail managers, and trail users. These evaluations indicate the validity of the design directions taken but highlight the need for information quality and quantity when encouraging participation from knowledgeable trail users, and the need for tools to ensure the continuing quality of further submitted information.

According to the urban planning of Zhengzhou City, the different types of functional areas of the city were used as evaluation objects, and the analytic hierarchy-composite index model was used to evaluate the geological environment risk and social economic vulnerability. The risk assessment model was used to evaluate the geological environment risk of Zhengzhou City. The evaluation results show that the area of high-risk area in Zhengzhou accounts for 4.05%; the area of medium-high risk area accounts for 12.89%; the area of medium-low and low-risk area accounts for 83.06%. According to the assessment results, suggestions are put forward to provide service for the urban planning, development and risk management. Highlights: * An urban geo-environment risk assessment technique system combining with the AHP - composite index assessment model is proposed. * Different types of functional zones in Zhengzhou City are taken as assessment units. * Geo-environment risk in Zhengzhou City is qualitatively and quantitatively evaluated.

Micro-tasking as a method for human assessment and quality control in a geospatial data import / Atle Frenvik Sveen in Cartography and Geographic Information Science, vol 47 n° 2 (February 2020)  

Public [article]  inCartography and Geographic Information Science > vol 47 n° 2 (February 2020) . - pp 141 - 152 Titre : Micro-tasking as a method for human assessment and quality control in a geospatial data import Type de document : Article/Communication Auteurs : Atle Frenvik Sveen, Auteur ; Anne Sofie Strom Erichsen, Auteur ; Terje Midtbo, Auteur Année de publication : 2020 Article en page(s) : pp 141 - 152 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique web [Termes IGN] algorithme de filtrage [Termes IGN] chevauchement [Termes IGN] contrôle qualité [Termes IGN] données localisées [Termes IGN] données localisées des bénévoles [Termes IGN] évaluation des données [Termes IGN] import de données [Termes IGN] OpenStreetMap [Termes IGN] précision des données [Termes IGN] production participative Résumé : (auteur) Crowd-sourced geospatial data can often be enriched by importing open governmental datasets as long as they are up-to date and of good quality. Unfortunately, merging datasets is not straight forward. In the context of geospatial data, spatial overlaps pose a particular problem, as existing data may be overwritten when a naïve, automated import strategy is employed. For example: OpenStreetMap has imported over 100 open geospatial datasets, but the requirement for human assessment makes this a time-consuming process which requires experienced volunteers or training. In this paper, we propose a hybrid import workflow that combines algorithmic filtering with human assessment using the micro-tasking method. This enables human assessment without the need for complex tools or prior experience. Using an online experiment, we investigated how import speed and accuracy is affected by volunteer experience and partitioning of the micro-task. We conclude that micro-tasking is a viable method for massive quality assessment that does not require volunteers to have prior experience working with geospatial data.

In this paper, we introduce a method for geometric comparison of a 3D indoor model with a reference, which is useful not only for evaluating the geometric quality of the model, but also for change detection and temporal analysis of the building. The method provides suitable criteria for the quantitative evaluation of the geometric quality in terms of completeness, correctness, and accuracy. Experimental evaluation on a synthetic dataset and the ISPRS benchmark dataset shows the potential of the proposed method for quantitative evaluation and localization of geometric errors in 3D models of indoor environments.
