СБОР И ПУБЛИКАЦИЯ ПРОСТРАНСТВЕННО-ВРЕМЕННЫХ ДАННЫХ ПО МАГИСТРАЛЬНЫМ ЭЛЕКТРИЧЕСКИМ СЕТЯМ РОССИИ НА ПРИМЕРЕ МОСКОВСКОЙ ЭНЕРГОСИСТЕМЫ

Электрические сети как предмет изучения географии транспорта на данный момент плохо освещены в отечественной и зарубежной литературе. С появлением высокодетальных космических снимков появилась возможность их использовать для сбора пространственных данных. Несмотря на попытки автоматизации распознавания ЛЭП на снимках, самый надёжный способ получения информации по-прежнему – визуальное дешифрирование. В рамках исследования проведён сбор пространственно-временной информации о магистральных электрических сетях на территории московской энергосистемы. Были использованы общедоступные данные дистанционного зондирования картографических веб-сервисов, а также архивные снимки с американских спутников Keyhole. В работе приведён пример изменения одного участка сети по снимкам за 1973 и 2018 годы. Сбор данных осуществляется с помощью Google Earth Pro и ArcGIS, анализ данных — скриптами модуля arcpy, подготовка данных к публикации – скриптами R, публикация данных в виде WMS (Web Map Service) выполняется с помощью QGIS Server. При анализе данные хранятся в базе геоданных ESRI, для публикации переводятся в открытый формат Geopackage Основной результат исследования доступен по адресу https://powerlines.one.

Real-Time Web Map Construction Based on Multiple Cameras and GIS

Previous VideoGIS integration methods mostly used geographic homography mapping. However, the related processing techniques were mainly for independent cameras and the software architecture was C/S, resulting in large deviations in geographic video mapping for small scenes, a lack of multi-camera video fusion, and difficulty in accessing real-time information with WebGIS. Therefore, we propose real-time web map construction based on the object height and camera posture (RTWM-HP for short). We first consider the constraint of having a similar height for each object by constructing an auxiliary plane and establishing a high-precision homography matrix (HP-HM) between the plane and the map; thus, the accuracy of geographic video mapping can be improved. Then, we map the objects in the multi-camera video with overlapping areas to geographic space and perform the object selection with the multi-camera (OS-CDD) algorithm, which includes the confidence of the object, the distance, and the angle between the objects and the center of the cameras. Further, we use the WebSocket technology to design a hybrid C/S and B/S software framework that is suitable for WebGIS integration. Experiments were carried out based on multi-camera videos and high-precision geospatial data in an office and a parking lot. The case study’s results show the following: (1) The HP-HM method can achieve the high-precision geographic mapping of objects (such as human heads and cars) with multiple cameras; (2) the OS-CDD algorithm can optimize and adjust the positions of the objects in the overlapping area and achieve a better map visualization effect; (3) RTWM-HP can publish real-time maps of objects with multiple cameras, which can be browsed in real time through point layers and hot-spot layers through WebGIS. The methods can be applied to some fields, such as person or car supervision and the flow analysis of customers or traffic passengers.

Mapping accessibility in Norway – a Method to Register and Survey the Status of Accessibility in urban areas and recreational areas

The Norwegian mapping authority has developed a standard method for mapping accessibility mostly for people with limited or no walking abilities in urban and recreational areas. We choose an object-orientated approach where points, lines and polygons represents objects in the environment. All data are stored in a geospatial database, so they can be presented as web map and analysed using GIS software. By the end of 2020, more than 230 out of 356 municipalities are mapped using that method. The aim of this project is to establish a national standard for mapping of accessibility and to provide a geodatabase that shows the status of accessibility throughout Norway. The data provide a useful tool for national statistics, local planning authorities and private users. The results show that accessibility is still low and Norway still faces many challenges to meet the government’s goals for Universal Design.

Methodology to Assess Sustainable Mobility in LATAM Cities

As the first step toward implementing strategies to improve mobility in urban centers, governmental authorities must assess their present situation in order to identify the most effective actions that should be included in their short and long-term plans. However, there is not a well-established methodology to carry out such an assessment. The already existing ones are subjective, incomplete, costly, and hard to implement, especially for the case of Latin American (LATAM) countries. This paper proposes a comprehensive methodology to carry out this assessment. It uses recent advances in information technologies and includes the use of web map services, telematics data, and low-cost vehicle emission tests. As an example of application, a mobility assessment was carried out for Saltillo, a medium-sized city in northeastern Mexico, which is considered a typical city in LATAM countries. Results indicate that this methodology can be replicated at a low incremental cost and that it leads towards the identification of the most sustainable (economic, environmental, and social) actions that should be implemented in these cities considering their local circumstances.

The Database of the Active Faults of Eurasia (AFEAD): Ontology and Design behind the Continental-Scale Dataset

Active faults are those faults on which movement is possible in the future. It draws particular attention to active faults in geodynamic studies and seismic hazard assessment. Here we present a high-detail continental-scale geodatabase: The Active Faults of Eurasia Database (AFEAD). It comprises 46,775 objects stored in the shapefile format with spatial detail sufficient for a map of scale 1:1M. Fault sense, a rank of confidence in activity, a rank of slip rate, and a reference to source publications are provided for each database entry. Where possible, it is supplemented with a fault name, fault zone name, abbreviated fault parameters (e.g., slip rate, age of the last motion, total offset), and text information from the sources. The database was collected from 612 sources, including regional maps, databases, and research papers. AFEAD facilitates a spatial search for local studies. It provides sufficient detail for planning a study of a particular fault system and guides deeper bibliographical investigations if needed. This scenario is particularly significant for vast Central and North Asia areas, where most studies are available only in Russian and hardcopy. Moreover, the database model provides the basis for GIS-based regional and continental-scale integrative studies. The database is available at https://doi.org/10.13140/RG.2.2.10333.74726 and via web map at http://neotec.ginras.ru/index/mapbox/database_map.html (last access: July 30, 2021). Some database representations with supplementary data are hosted at http://neotec.ginras.ru/index/english/database_eng.html.

Collaborative Cataloging of Spanish Industrial Heritage Assets through Teaching in Project Management Subjects

The cataloguing experience presented addresses two key challenges of cataloguing industrial heritage assets. On the one hand, despite their value and interest, some of these assets are little known and difficult to identify. Moreover, on the other hand, this heritage typology needs further promotion and valuation. In this context, collaborative cataloging responds to both challenges from its initial approach. Unlike cataloging tasks developed by small teams, involving many people throughout the territory allows to take advantage of the local knowledge of each participant. However, in addition, each participant contributes to the dissemination of the goods collected in the generated catalog. First in a passive way, when knowing the contributions of the rest of the participants. Secondly, actively, by disseminating the cataloging initiative developed among their contacts. This cataloguing experience has been developed with the students of the subject Environmental Project Management during the last four courses. The assets selected by the students (106) as case studies to develop a reuse project are shown in an open web map, which includes the narrated video presentation of the proposal developed for some of them (25). The obtained results contribute both the identification and promoting of this kind of assets.

Planning and co-creation of Quadrilatero Ferrifero cultural landscape

The article presents results about Geodesign studies of the Iron Quadrangle (Quadrilátero Ferrífero – QF) that are under development since 2016, based on economic, environmental, and social approaches, with the goal to promote cultural landscape planning based on shared process, giving support to collective and individual opinion making. This paper has the goal do present the Brazilian Geodesign platform, called “GISColab”, that was first tested in QF case study. The QF area is characterized by conflicts of interests due to mining activities, urban growth, cultural heritage landscapes and the presence of areas of environmental protection. QF is especially important as part of the economic structure of the state of Minas Gerais (Brazil) but became globally known due to a couple of environmental disasters that caused the death of almost 300 people. In the first studies we used Steinitz´s framework (2012), but some difficulties in the process were observed, what led to the proposal of a new platform and framework, more adapted to inequalities related to access and use of information, so that people could really act as participants of all the steps. The new web-platform is based on Spatial Data Infrastructure (SDI), which receives a considerable amount of data and is open to receive further information via Web Map Service (WMS), which guarantees the users will construct, by themselves, judgments about these areas. It presents a shared process of decision making by digital dialogues, as by voting based on Delphi method. The platform and process are based on geovisualization, interoperability and the co-creation of ideas based on geo-collaboration.
