Discovering the local in national cultural heritage collections. How web maps can help the UK public engage with their ‘own places’

ABSTRACT Identity is a critical influence on the public’s engagement with cultural heritage. This article emphasises the role of geographical scale in this relationship examining how the presentation of local heritage can foster meaningful engagement with collections. The geographical information embedded in digital collections – such as where objects were made or the locations they depict and describe – can help varied audiences to discover digital heritage records that are significant to them. Yet the interactive web maps used by cultural heritage organisations have not presented the breadth of collections effectively. Audience research conducted by the Locating a National Collection project offered insights into how the presentation of local heritage using web maps can broaden engagement. A survey explored the values, motivations and identities of the UK public in relation to geography and web technologies. ‘Pretotypes’ or sketches of interfaces prompted focus groups to offer insights into interface design and the suitability of collections. The public were not only interested in heritage connected to the area where they reside but also a range of familiar locations drawn from memory, genealogy and community, termed their ‘own places’. Only particular collections offer geographical information of suitable quality and distribution to support engagement with familiar locations at a local scale. This user-centred approach can help organisations to design web maps that help audiences discover the parts of collections they find meaningful. The article offers the first step in a pathway to achieving social impact such as community building through digital collections.

A Framework for Co‐designing and Developing Participatory Storymaps with Aboriginal Communities

AbstractThe research reported in this paper is part of an ongoing project on promoting Aboriginal cultural storytelling using mobile participatory mapping applications and web‐based interactive storymaps. This paper presents a conceptual framework for developing a co‐designed participatory storymap. The storymap aims to ubiquitously collect location‐based knowledge and stories in both online and offline modes, as well as present an interactive web map that dynamically integrates information recorded as georeferenced texts, images, audios, and videos. The participatory mapping has a potential to allow Aboriginal communities to capture and preserve their cultural heritage on their own using a smartphone or tablet. Ethical co‐designing process of implementing the storymaps is also discussed.

Mapping of enviromental pollution of air in Lviv

The condition and composition of air in Lviv are influenced by two main factors: the introduction of pollutants into the atmosphere through various sources and harmful physical effects on it. The latter includes radiation, sound vibrations, noise, and so on. These and other factors disrupt the optimal conditions of the air, which negatively affects human health and the condition and development of animals and plants. The main sources of pollutants in the air of Lviv are as follows: dust — vehicles, woodworking and building materials industry; sulfur dioxide — industrial enterprises, carbon monoxide — vehicles, thermal power plants; nitrogen dioxide — heat power companies; formaldehyde — motor transport, woodworking industry. Today, emissions from mobile sources are the biggest air pollutants in the city. The chemical composition of emissions from mobile sources of pollution is characterized by the predominance of carbon monoxide (up to 74 %), nitrogen compounds, and hydrocarbons (12 % and 11 %, respectively). Today the state of atmospheric air in large cities of Ukraine and, in particular, in the city of Lviv is at an unsatisfactory level. The main problems in this area are the progressive nature of the negative impact on the ecological state of the environment and human health. As there is currently no interactive cartographic material that can visualize the problem of environmental pollution, the main purpose of this work was to create an interactive web map of the quality of life of the population of Lviv in terms of air pollution. To achieve this goal, we collected and systematized geospatial statistical cartographic materials on the ecological conditions of the air in Lviv. The necessary software for the development of an interactive map of air pollution has been selected, and its possibilities have been studied. An algorithm for loading geospatial data into the created web resource has been developed. A template of applications for creating web maps of air pollution in Lviv was selected according to the indicators of 2020, which were measured at 30 crossroads of the city. Thus, two interactive web maps of air pollution in Lviv were developed in the environment «Google My Maps» and «ArcGIS Online».

From Data to Narratives: Scrutinising the Spatial Dimensions of Social and Cultural Phenomena Through Lenses of Interactive Web Mapping

Modern web mapping techniques have enhanced the storytelling capability of cartography. In this paper, we present our recent development of a web mapping facility that can be used to extract interesting stories and unique insights from a diverse range of socio-economic and demographic variables and indicators, derived from a variety of datasets. We then use three curated narratives to show that online maps are effective ways of interactive storytelling and visualisation, which allow users to tailor their own story maps. We discuss the reasons for the revival of the recent attention to narrative mapping and conclude that our interactive web mapping facility powered by data assets can be employed as an accessible and powerful toolkit, to identify geographic patterns of various social and economic phenomena by social scientists, journalists, policymakers, and the public.

Sonification of Spatial Data: An Online Audiovisual Cartographic Representation of Fire Incidents

Abstract. The possibilities of using sound in cartography have been formulated by numerous researchers. However, there are still no general guidelines for mapping data dimensions to auditory variables, while the decision of which spatial data dimension to represent by which sound variable is crucial. The method for embedding sound in maps is commonly known as "sonification"; the representation of data through sound. Many researchers use sonification to convey their data through the auditory channel as an alternative way to understand and represent our complicated world. With this in mind, we created an interactive web map that depicts the fire dynamics, adopting the sonification technique of parameter mapping; a sound variable was used to represent fire duration. For assessing the effectiveness of different sound variables for this map, an online survey was conducted. The main finding is that to represent spatial data through sound, participatory approaches can highlight the most effective cross-modal correspondence.

Interactive HGIS platform union of lublin (1569): A geomatic solution for discovering the Jagiellonian heritage of the city

• Lublin Historical GIS is the first www platform in Poland developed with object-oriented approach dedicated to present historical narrations. • The portal is based on four-pillar types of data: events, places, people and sources linked in multirelational matrix. • The developed CMS is integrating various multimedia so that the portal editors (journalists, historians - generally humanists) dont have to have technological skills to develop attractive, deep spatial narratives. • The case presented is so far the deepest and the most accurate historical reconstruction of Lublin in the 16th century. • The users visiting teatrnn.pl/unia-lubelska can explore the vast digital world of 16th-century Lublin at their own pace and with the individual intrests. Lublin in the period of the Lublin Union (1569) is an interdisciplinary research project conducted by the “Grodzka Gate – NN Theatre” Centre in Lublin as a part of the celebration of the 450th anniversary of signing the Union of Lublin Act - one of the most important historical events in 16th-century Europe, during which the Polish-Lithuanian Commonwealth was constituted. This paper aims to present the research process by which an innovative Historical GIS web platform, based on an object-orientated database design, was tested and refined. The portal uses four pillars of spatial-temporal databases (events, people, places, sources) to collect data and develop historical narratives presenting various events in the history of the city and the region. The idea behind the project was to develop an Internet portal that would acknowledge modern users with the historical event of the Union of Lublin from the perspective of the then resident of Lublin. What is known about the 16th-century Lublin? What did the city and its surroundings look like? Who lived in Lublin? Who used to visit it? What architectural elements and traces of cultural heritage have been saved to this day? The reconstruction of the 16th-century urban space was carried out using the retrogression method of 11 early plans and maps of Lublin, verified and supplemented with the latest archaeological findings, accurate architectural research (geo-radar, laser scanning) and an extensive archival query. Thanks to the Historical GIS technology, the research results have been published in the form of a universal platform ( www.teatrnn.pl/unia-lubelska ), with an interactive web-map of 16th-century Lublin (Google Maps API implementation) and modelling urban facilities with 3D technology (SketchUp & Unity). The designed technological solution is scalable, making it possible to search and combine individual records (e.g. person-event-address) as well as entire groups of records on higher hierarchical levels (social groups - sequences of events - multifaceted maps). The portal editing panel is dedicated to humanists (historians, journalists, sociologists, etc.) without specialist knowledge of GIS. The functions integrated with the CMS facilitate mapping the content collected in the database and embedding the narration in an adequate context of the historical space. As a result, editors preparing a thematic article have a searchable set of documents, facts, people and places at their disposal, and their task is to fill the narrative with descriptive content. This is a universal model for building deep maps and spatial narratives.

Interactive web mapping tools and custom subsurface cross-sections for interdisciplinary geologic investigation

Using Python-based geospatial analytics, open-source web mapping technologies, geophysical data models, and subsurface stratigraphy models from the Regional Geology Geologic Framework Model database assembled by Los Alamos National Laboratory, we developed a suite of web-based geologic investigation tools to identify and understand subsurface structures and geophysical properties concerning salt and shale formations within the contiguous United States. Coupled with a web map interface, these tools allow for the interactive visualization of various geologic data and demonstrate the ability to quickly generate custom subsurface cross-sections, borehole charts, and diagrams for azimuthal orientation data. These capabilities were developed for stakeholder and researcher use to facilitate informed decision making for spent nuclear waste disposition. However, these capabilities provide a flexible model for a variety of subsurface investigation needs, and we have demonstrated this flexibility by adapting these tools to meet visualization needs for various subsurface models within a web-based platform.

Interactive Web Maps: Usability Heuristics Proposal

Abstract. With the evolution of technology, maps have changed how they are produced and consumed. In the 1990s, along with the internet uprise, printed and digital maps began to be shared and viewed on the web, which provided more significant user interaction with the map and geographic data. However, the ease of creating interactive maps using computational resources sometimes neglects cartographic concepts, impairing the interpretation of geographic data and the quality of the interaction between user and system. This work presents ten specific Usability Heuristics for Interactive Web Maps to identify and elaborate a set of criteria that help create and evaluate the quality of interactive web maps. For this, we used a methodology to develop domain-specific Usability Heuristics, composed of eight steps. This paper presents the ten heuristics elaborated along with the attributes of the name, ID, category and definition, and an additional checklist. This new set encompasses both the concepts of cartography and usability, contributing to better user interaction with the system and geographic data.

Flood Risk Communication Using ArcGIS StoryMaps

In Canada, flooding is the most common and costly natural hazard. Flooding events significantly impact communities, damage infrastructures and threaten public security. Communication, as part of a flood risk management strategy, is an essential means of countering these threats. It is therefore important to develop new and innovative tools to communicate the flood risk with citizens. From this perspective, the use of story maps can be very effectively implemented for a broad audience, particularly to stakeholders. This paper details how an interactive web-based story map was set up to communicate current and future flood risks in the Petite-Nation River watershed, Quebec (Canada). This web technology application combines informative texts and interactive maps on current and future flood risks in the Petite-Nation River watershed. Flood risk and climate maps were generated using the GARI tool, implemented using a geographic information system (GIS) supported by ArcGIS Online (Esri). Three climate change scenarios developed by the Hydroclimatic Atlas of Southern Quebec were used to visualize potential future impacts. This study concluded that our story map is an efficient flood hazard communication tool. The assets of this interactive web mapping tool are numerous, namely user-friendly mapping, use and interaction, and customizable displays.

Exploring the nexus between transdisciplinarity, internationalisation and community service-learning at a university of technology in Cape Town

Background: The ability of the South African citizenry to overcome a myriad of challenges (which include the triple challenges of inequality, poverty and unemployment) can be called into question.

CPUT, University of Michigan, St. Mark’s Church and District Six Museum. The aim of the collaboration was to develop an interactive Web map, which would display the socio-spatial information based on the baptismal records of the former residents of District Six.Methods: The article explores interconnections between transdisciplinary education, internationalisation of higher education and community service-learning. The discussion is based on the authors’ reflective analysis of the deployment of the triad of concepts in the initiative reported on.Results: Intricate interdependencies were discovered between transdisciplinarity, internationalisation of higher education and community service-learning.Conclusion: It is proposed that future teaching and learning initiatives employ a critical lens and the notion of complexity to meticulously explore the aforesaid concepts towards extending the frameworks for higher education.

Healthy Aging Data Reports: Measures of Community Health to Identify Disparities and Spur Age-Friendly Progress

This translational research had 2 aims: first, to analyze and translate data from multiple original data sources to provide accurate, unbiased local community and statewide information about healthy aging; second, to work with stakeholders to use the tools to identify disparities in healthy aging and to support their efforts to advance healthy aging. Data sources from the Centers for Medicare and Medicaid Services, Behavioral Risk Factor Surveillance System, U.S. Census American Community Survey, and other sources were analyzed using small area estimation techniques to determine age/gender-adjusted local community rates in Connecticut (CT), Massachusetts (MA), New Hampshire (NH), and Rhode Island (RI). State-level analyses revealed gender and racial/ethnic disparities in healthy aging. A factor analysis identified 4 dimensions of community population healthy aging/morbidity: serious complex chronic disease, indolent conditions, physical disability, and psychological disability. Healthy Aging Data Reports now exist for MA (2014, 2015, and 2018), NH (2019), RI (2016 and 2020), and CT (2021) and demonstrate differences in health by place. Each report includes community profiles for every city, town, and some urban neighborhoods with more than 170-197 indicators. The reports include maps of the statewide distribution of rates, an infographic, highlights report with state-specific multivariate analyses, and 18 interactive web maps, 18 regional interactive web maps, and technical documentation about data sources and methods. Overall, the research has identified variations in healthy aging and provided tools to track change over time to support age-friendly efforts in the region.

EXPERIMENTAL RESEARCH OF THE ACCURACY OF NAVIGATION GNSS - RECEIVERS IN CONDITIONS OF THE CONSTRUCTED TERRITORY

Use of digital geodetic support technologies with the use of GNSS satellite systems in combination with electronic geodetic instruments, introduction of new methods of construction of geodetic networks, collection of information by ground and aerospace surveying, unification of exchange formats of measurement results based on computer technologies and their application conditions. Substantiation and development of remote methods of spatial information collection requires analysis and consideration of a number of errors in order to improve accuracy.
 Wikimapia is a map project for shared use with open content, which aims to identify all geographical objects with the introduction of useful information about them. It combines an interactive web map and a Wiki system.
 One of the features of the Wikimapia resource is that it is possible to determine geographical coordinates. To do this, you need to move the cross cursor on the object of interest and get its coordinates visually.
 The purpose of the study was to determine the accuracy of the coordinates of GPS receivers Garmin Oregon 450 in the built-up area, using as a basis for calibration, the resource "Wikimapia".
 In order to determine the accuracy of the location with the help of GARMIN Oregon 450 GPS receivers, GNSS measurements were performed at 30 marker points.
 Ellipsoidal coordinates were recalculated into spatial rectangles according to known formulas.
 In order to assess the accuracy of determining the location of marker points, the differences in the coordinates of their position were found and the root mean square error from a number of measurements was found.
 The average error of coordinate measurements was ± 4.79 m for the GPS receiver.
 Based on experimental research, the possibility of using the resource "Wikimapia" not only to quickly determine the coordinates of topographic objects, determine their categories, but also with sufficient accuracy to apply for the calibration of navigation GNSS receivers when there is no network of geodetic points.
 A promising direction in the process of scientific and practical research should be the creation of a general mathematical model for predicting the influence of the plurality on the location and improvement of navigation aids.

CREATING INTERACTIVE WEB MAPS FOR THE CITY

The features of creating interactive web-maps on the territory of the city are considered. In a separate category maps created with Google, Yandex, OSM mapping a substrate with a certain set of points of interest (POI), and maps created with GIS applications. The technology of creating an interactive map is proposed, which includes the main stages: designing a mathematical basis, creating a geo-graphic basis, forming thematic databases, creating a web map. In the framework of this technology, the scale levels of the map are determined, and the choice of the cartographic projection is considered. The sources for creating an interactive map are identified, namely, the geographical basis, housing and utilities reform data, and thematic data. The interrelations of thematic objects with general geographical elements of the map content are established. A technological scheme for creating and filling a spatial database for a city site is presented. The stage of forming thematic data from various sources is considered. The technological scheme of creating an interactive web map is presented. The process of creating interactive logic is described. This technology allows you to easily make updates to the thematic database, which provides quick access to the information of the end user.

A database of global storm surge reconstructions

Storm surges are among the deadliest coastal hazards and understanding how they have been affected by climate change and variability in the past is crucial to prepare for the future. However, tide gauge records are often too short to assess trends and perform robust statistical analyses. Here we use a data-driven modeling framework to simulate daily maximum surge values at 882 tide gauge locations across the globe. We use five different atmospheric reanalysis products for the storm surge reconstruction, the longest one going as far back as 1836. The data that we generate can be used, for example, for long-term trend analyses of the storm surge climate and identification of regions where changes in the intensity and/or frequency of storms surges have occurred in the past. It also provides a better basis for robust extreme value analysis, especially for tide gauges where observational records are short. The data are made available for public use through an interactive web-map as well as a public data repository.

Using Real-Time Data to Detect Delays and Improve Customer Communications at New York City Transit

New York City Transit operates one of the world’s largest transit systems, and it can be difficult for the agency’s communications team to keep track of the numerous service disruptions that need to be communicated to customers. This paper introduces the Transit Visualization tool, which processes real-time train location data to automatically identify areas of the system where service may not be living up to customers’ expectations. Specifically, the Transit Visualization is set up to identify areas of the system where trains are operating at lower-than-normal speeds and areas of the system where there are atypically long gaps between trains. Any occurrence of slow speeds or long gaps is assigned a severity level (Moderate, Severe, or Very Severe) to indicate the magnitude of the problem. An overview of any problems the application identifies is shown on an interactive web map, as well as on several easy-to-digest summary tables. The map also displays real-time locations of trains and buses throughout the transit system. The Transit Visualization has been successfully rolled out to the subways communications team and has become a mission-critical tool for communicating delays to customers, especially during the course of the COVID-19 pandemic.

Community Catalyst: Building a Water Sanitation System for Social Inclusion in Winneba, Ghana

Located on the coast of the Gulf of Guinea in Ghana, West Africa, the city of Winneba boasts one of the important ecological wetlands inscribed on the list of Ramsar Sites. However, Winneba faces daunting environmental, economic and social challenges—e.g. water sanitation crisis, infrastructure deficiency, environmental degradation, gender inequality, and social conflicts—interacting with each other to create a vicious cycle. Based on a collaborative workshop, a “crowd-sourcing” decisionmaking process, on-site fieldworks, and an Interactive Web Map, the project team develops in-depth study of the social context and traditional customs of Winneba. A water sanitation system, also as a network of public spaces that facilitates ecological and social improvement, is proposed. It includes drainage systems, rain gardens, water kiosks, orchards, public biogas toilets, and organic waste collection stations. Combining a three-phase implementation, i.e. establish the concept of public space, create a site through collaborative work, and connect communities, the project team introduces a bottom-up incentive system that encourages local community residents to collaborate and participate in constructing and maintaining the public space system for their communities, so as to improve the wellbeing of the communities and the city. Not just proving a design strategy for a kind of public space or a plan for a network of urban green space system, this project sets an exemplar to long-term sustainable management of water sanitation system through self-government of residents and communities in developing countries.
