Previous works using call detail records (CDRs) tend to focus on modeling the spatial and temporal patterns of human mobility, not paying much attention to the semantics of places, thus failing to model and enhance the understanding of the motivations behind people’s mobility. In this paper, we applied a methodology for identifying individual users’ routine locations and propose an approach for attaching semantic meaning to these locations. Specifically, we used circular sectors that correspond to cellular antennas’ signal areas. In those areas, we found that all contained points of interest (POIs), extracted their most important attributes (opening hours, check-ins, category) and incorporated them into the classification. We conducted experiments with real-world data from Coimbra, Portugal, and the initial experimental results demonstrate the effectiveness of the proposed methodology to infer activities in the user’s routine areas.

Discovering transition patterns among OpenStreetMap feature classes based on the Louvain method / Yijiang Zhao in Transactions in GIS, vol 26 n° 1 (February 2022)  

Public [article]  inTransactions in GIS > vol 26 n° 1 (February 2022) . - pp 236 - 258 Titre : Discovering transition patterns among OpenStreetMap feature classes based on the Louvain method Type de document : Article/Communication Auteurs : Yijiang Zhao, Auteur ; Wentao Yang, Auteur ; Yizhi Liu, Auteur ; et al., Auteur Année de publication : 2022 Article en page(s) : pp 236 - 258 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique web [Termes IGN] Açores, archipel des [Termes IGN] algorithme glouton [Termes IGN] données localisées des bénévoles [Termes IGN] étiquette [Termes IGN] géobalise [Termes IGN] Indiana (Etats-Unis) [Termes IGN] OpenStreetMap [Termes IGN] réseau routier Résumé : (auteur) Numerous studies have shown that OpenStreetMap (OSM) data can achieve high positional quality. However, the thematic attributes of OSM objects can be modified several times, which has a large impact on semantic heterogeneity. Identifying transition patterns within OSM feature classes is an important preliminary step for the tag recommendation algorithm, which can reduce the number of modifications and enhance the efficiency of OSM data updates. In this article, we propose an approach for discovering transition patterns among OSM feature classes. We first produced the transition matrix of feature classes and then developed a graph. Next, the Louvain method for community detection was utilized to cluster the feature classes. OSM data from Indiana, USA, and the Azores, Portugal, were used for our experiments. Some transition patterns were discovered: (1) many feature classes with the most transitions are the same in both datasets and most transitions occur in road-related feature classes; (2) people tend to tag general classes if they are unsure of the specific classes of tagged objects; and (3) most class transitions occurred as a result of volunteers improving the specificity and precision of feature classes. Moreover, consistently confusing concept pairs were identified.

Conservation zones increase habitat heterogeneity of certified Mediterranean oak woodlands / Teresa Mexia in Forest ecology and management, vol 504 (15 January 2022)  

Public [article]  inForest ecology and management > vol 504 (15 January 2022) . - n° 119811 Titre : Conservation zones increase habitat heterogeneity of certified Mediterranean oak woodlands Type de document : Article/Communication Auteurs : Teresa Mexia, Auteur ; Xavier Lecomte, Auteur ; Maria Conceição Caldeira, Auteur ; et al., Auteur Année de publication : 2022 Article en page(s) : n° 119811 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] biométrie [Termes IGN] certification forestière [Termes IGN] chênaie [Termes IGN] conservation des ressources forestières [Termes IGN] écosystème forestier [Termes IGN] forêt méditerranéenne [Termes IGN] gestion forestière durable [Termes IGN] Portugal [Termes IGN] Quercus suber [Termes IGN] régénération (sylviculture) [Termes IGN] sous-étage [Termes IGN] sylvopastoralisme [Vedettes matières IGN] Ecologie forestière Résumé : (auteur) Forest certification is a conservation tool, which aims to promote the sustainable management and conservation of forest ecosystems. Establishing set-aside or lower intervention conservation zones to promote biodiversity conservation is a requisite of forest certification. We tested the effects of conservation zones on the tree biometrics and regeneration, as well as on the taxonomic, functional, and structural diversity of the shrub and herb understory, in Mediterranean oak woodlands. We also assessed how oak biometrics, regeneration and understory diversity varied among conservation zones established 10, 14, and 20 years before our sampling dates. Oak regeneration tended to be higher in conservation zones than in controls, but results varied with the age of conservation zones. For example, the abundance of oak seedlings and saplings was higher in 10-year-old conservation zones than in those established 20 years ago. Abundance of young oak trees was higher in 14-year-old conservation zones than in 10- and 20-year-old conservation zones. The understory vertical diversity was significantly higher in 14- and 20-year-old conservation zones than in controls. Functional diversity differed significantly between conservation zones and controls, with a higher abundance of late-successional shrubs, namely fleshy-fruited species in 20-year-old conservation zones. The plant species composition of the shrub and the herb understory was most dissimilar between older conservation zones and controls. Additionally, the cover and diversity of the understory herb species decreased with the age of conservation zones. Conservation zones implemented under forest certification increase habitat structural complexity of oak woodlands, which may benefit wildlife species, but there will be trade-offs with the cover and diversity of the herb understory. Forest managers must evaluate such trade-offs when establishing conservation zones in cork oak woodlands under forest certification schemes.

Evaluating narrative in geoportals for territorial public policies / Luis Manuel Batista in Cartographica, vol 56 n° 4 (winter 2021)

At the Portuguese municipal level, the municipal master plan (PDM – plano diretor municipal) is the territorial management tool responsible for long-term territorial planning and ordering. Since the PDM will constrain the citizens’ lives, it should be of easy access and interpretation. However, due to its large amount of information, it is often hard for them to understand what is presented using only static cartographic elements. Comparing 60 Web sites that present geographical information for a wider public, we found that narrative, visual, and interactive elements and data presentation in flexible portions with the necessary information for partitioning, browsing, or querying made the data more engaging. This flexibility is particularly important with large data sets, where decreasing the level of complexity is vital for proper understanding and analysis. We found that geoportals dedicated to territorial public policies lack narrative elements that would improve comprehension. Since it is difficult for the general public to understand the strategy the municipality wants to implement, the desired public participation, although possible, will return poor results.

How national forest funds can support small-scale forest businesses to deliver ecosystem services / Ludwig Liagre in Austrian journal of forest science, vol 2021 n° 4 (2021)  

Public [article]  inAustrian journal of forest science > vol 2021 n° 4 (2021) Titre : How national forest funds can support small-scale forest businesses to deliver ecosystem services Type de document : Article/Communication Auteurs : Ludwig Liagre, Auteur ; Alex Pra, Auteur ; Davide Pettenella, Auteur Année de publication : 2021 Langues : Anglais (eng) Descripteur : [Termes IGN] Costa Rica [Termes IGN] financement [Termes IGN] Guatemala [Termes IGN] Luxembourg [Termes IGN] Portugal [Termes IGN] service écosystémique [Termes IGN] Tanzanie [Vedettes matières IGN] Economie forestière Résumé : (auteur) National Forest Funds (NFFs) represent an increasingly relevant funding source for the forest sector at the global level. With the increasing role of NFFs, their structures and operational procedures are becoming more complex and diversified. While many of these funds are State-driven and often support projects that include public goods with a focus on social and environmental benefits, some also support privately managed small-scale “for profit” businesses related to wood and non-wood forest-based value chains. This paper describes some the recent developments of NFFs and presents the results of a research effort that analyzed how NFFs’ funding targeting small-scale forest enterprises can contribute to the provision of forest ecosystem services. For this analysis, five case studies from Costa Rica, Guatemala, Luxembourg, Portugal, and Tanzania have been selected. In specific, the Forest Financing Fund (FONAFIFO), the FONABOSQUE, the Forest and Climate Change Fund (FCCF) of Luxembourg, the Floresta Atlantica Fund, and the Tanzania Forest Fund (TaFF) are reviewed. The research addressed several key research questions, including: How are NFFs operations conceived to support small-scale forest businesses? What type of funding windows are targeting small-scale enterprises? What are the current practices of NFFs supporting ES provision through small-scale forest businesses? How could NFFs further support small-scale enterprises while unleashing contributions to the provision of ES?
