Increasing OpenStreetMap Data Accessibility with the Analysis-Ready Daylight Distribution of OpenStreetMap: A Demonstration of Cloud-Based Assessments of Global Building Completeness
Jennings Anderson, Timmera Whaley Omidire

A recent release of new scientific datasets generated from OpenStreetMap exemplifies the need for analysis-ready repositories of OSM data that require minimal pre-processing. We created the Analysis-Ready Daylight OpenStreetMap Distribution to provide researchers with the opportunity for simple cloud-based SQL queries of nearly 1B OSM features. We demonstrate the capabilities with intrinsic and extrinsic data coverage assessments of OSM buildings globally.

OSM Sidewalkreator - A QGIS plugin for automated sidewalk drawing for OSM
Kauê de Moraes Vestena

Sidewalks are a relevant part of the living space in urban environments, but there are still few mapped sidewalks. In recent years, the mapping of sidewalks has grown in importance among the OSM and academic communities. To cover up this gap, we propose a Github-hosted, fully open-source QGIS Plugin entitled "OSM SidewalKreator" to automatically draw for OSM the geometries of sidewalks crossings and kerb crossing interfaces. Furthermore, the tool gives the user the capacity to control the process. Then, deepen, improve, and increase the amount of sidewalk mapping in OpenStreetMap to improve accessibility and mobility worldwide.

The cell size issue in OpenStreetMap data quality parameter analyses: an interpolation-based approach
Silvana Philippi Camboim

The quality of OSM data is dependent on many different factors and is quite heterogeneous. Therefore, in both intrinsic and extrinsic quality parameter analyses, a common practice is subdividing the study areas into subareas. In this paper, we worked on a method for obtaining the optimal grid cell size for OSM data quality analysis. Furthermore, we proposed that if the quality is homogeneous in a region, it can be estimated using an IDW interpolation. . In this summary, we have done a preliminary analysis for a Brazilian city, Curitiba, with about 28,000 points of known accuracy.

Corporate editing and its impact on network navigability within OpenStreetMap
Corey Dickinson

Using intrinsic quality indicators we explore how network quality, in terms of its suitability for navigation, varies across areas with relatively high and low corporate editing in OpenSteetMap. Our work shows areas with relatively high rates of corporate editing exhibit not only an overall increase in data quality, but also increased rates at which quality improves.

Automated derivation of public urban green spaces via activity-related barriers using OpenStreetMap.
Theodor Rieche

Urban green spaces serve people for active and passive recreation. On the basis of OpenStreetMap data, suitable green spaces are to be derived in order to incorporate them as recreation destinations in a location-based service (the “meinGruen” app) as polygons. The modelling approach focuses on activity-related barriers in the context of urban green, transitions between different land use classes, and public accessibility. The case study was implemented for the city of Dresden in Germany.

Null Island - a node of contention in OpenStreetMap
Peter Mooney, Levente Juhász

Null Island is where the prime meridian meets the equator at (0,0) longitude and latitude. While Null Island is a fictitious, dimensionless, point object, its existence stimulates vigorous debate making it worthy of serious consideration. Many examples exists illustrating how Null Island impacts OSM discourse. Our study considers what the geographic oddity of Null Island means for OSM. The main contribution is a structured knowledge-based resource facilitating understanding of Null Island’s impact on OSM. This socio-technical and philosophical investigation of Null Island can become a catalyst for deeper discussions and debates in OSM around mapping practices.

OSM for sustainable transport planning
Greta Timaite, James Hulse, Robin Lovelace

OpenStreetMap (OSM) data has the potential to facilitate bottom-up approach to transport planning which is essential for localized data-driven policy interventions. Given this, OpenInfra project is exploring the potential of OSM data in transport research with a focus on active travel. The exploration showed that currently missing data limits the applicability of OSM data. Nevertheless, we argue that the potential and relevance of OSM data can be demonstrated by recategorizing OSM data to provide more actionable insights to policy-makers. This, therefore, could encourage the uptake of open data leading to more transparent, reproducible, and participatory transport planning.

Combining Volunteered Geographic Information and WPdx standards to Improve Mapping of Rural Water Infrastructure in Uganda.
Stellamaris Nakacwa

The lack of data on the distribution of the water resources, possess a great challenge for the water resource investment and AI/ML-enabled advancements in the water sector compared to all other sectors like heath. This paper describes the methodology for combining different water mapping schemas to create comprehensive multi-platform water infrastructure data and enhance rapid updates to support a suite of water resource analytics and extended advanced technology explorations towards improved decision-making.

Leveraging OpenStreetMap to investigate urban accessibility and safety of visually impaired pedestrians
Sagi Dalyot

Cities worldwide encourage urban active mobility by advocating policy and planning. Although contribution is evident, in practice, these actions disregard population parts that have mobility impairments. This research suggests using OpenStreetMap data in customized analytical models to assess the accessibility level of the urban environment for visually impaired pedestrians. Models results show the existence and spatial distribution of existing accessibility problems, including challenging street network connectivity and dangerous walking areas. These models can be used to enable decision makers, city stakeholders and practitioners to enrich management, monitoring and development of their cities, and support sustainable, livable lifestyles and walkability equality.

Understanding and modelling accessibility to public green in large urban centers using OpenStreetMap data
Alice Battiston

OpenStreetMap data represents a valuable source of information for public green areas in large urban centers and effectively measures the United Nations' Sustainable Development Goal 11.7. Our study provides a threefold contribution in this direction. First, we validate land-use-related tags in OpenStreetMap, through a comparison with satellite data from the European Urban Atlas. We then propose a framework and an interactive tool to measure access to public green areas through several established indices. Finally, we show how the framework can be used to simulate the impact of new green areas and help policymakers design effective interventions.

YouthMappers: A Hybrid Movement Design for the OpenStreetMap Community of Communities
Patricia Solis

The YouthMappers experience lends itself to explore interesting questions about the cultural and organizational aspects of data production and usage practices in OpenStreetMap, in order to improve them. First, this study aims to identify what are some of the qualitative and quantitative characteristics distinguishing the performance of YouthMappers as an academic-based community within OSM. Second, this study aims to better understand how the design approach taken by and on behalf of YouthMappers reinforces an identity as unique contributors.

Landmarks for accessible space – promoting geo-literacy through geospatial citizen science
Sagi Dalyot

Geo-literacy provides skills to read, interpret and use geospatial information, where little evidence exists regarding the potential and capacity of new education programs in advancing these skills. We present a citizen science project held in 13 high schools in Israel, where the students practice participatory mapping with OpenStreetMap to map features relevant to the navigation of visually impaired pedestrians. We show that students improve their geospatial thinking and reasoning skills, including their self-esteem. We believe that this research contributes to various pedagogic and education levels, in terms of theoretical knowledge about the integration of innovative geo-literacy programs.

Mapping crises, communities and capitalism on OpenStreetMap: situating humanitarian mapping in the (open source) mapping supply chain
Anne Lee Steele

This proposal expands an understanding of humanitarian mapping from an ethnographic perspective, seeking to understand the complex mechanics behind this confluence of humanitarianism, technology, and crowdsourced labor. It seeks to scaffold a notion of the “open source mapping supply chain”, situating both humanitarian mapping and OpenStreetMap itself within a larger ecosystem of commercial, humanitarian, open source, government, and other actors in developing geospatial-related technologies.
