OpenStreetMap provides a lot of valuable information about urban green spaces, but the numerous and conceptually overlapping OSM tags that describe such features lead to spatially heterogenous representations in OSM. We developed an exploratory data analysis methodology to identify locally relevant OSM tags for mapping green spaces in a specific area and compared the extracted OSM features to admi...

We propose a model that uses only open data for estimating the minimal energy use of individual buildings for heating and cooling at scale. The workflow is divided in two main blocks: (i) predicting at scale a 3D building stock using OpenStreetMap data, and (ii) estimating the energy use of buildings individually with a back-end model. For mitigating climate change, it is crucial to minimize energ...

This talk will present the rise of active, self-standing grassroots communities in Haiti, Western and Central Africa since 2010 resulting from a unique set of continued support actions replicable in other territories, by an ensemble of speakers from (at least) France, Burkina Faso, Senegal and Togo This breakout session will produce a narrative about how since 2010, OpenStreetMap communities emerg...

Over the last few months, we’ve been building an offline first field mapping tool for the OpenStreetMap ecosystem called Observe. Observe makes field surveying, and verification easy for mappers, and works on iOS and Android. My talk will cover how Observe integrates with mapping workflows and helps improve OSM data from the field. I'll also touch upon fundamentals of building Observe and our assu...

Digitalisierung und Nachhaltigkeit sind die entscheidenden, existenziellen Herausforderungen des 21. Jahrhunderts.

This technical talk will introduce Hikar, detail the many new developments since it was last presented at SOTM Birmingham 2013, and describe how it works in technical de...

Currently everyone uses the same seccomp rules for running their containers. This tool allows us to generate seccomp rules based on what the container actually requires and allows us to lock down the container. We had a GSOC student this summer who instrumented podman to allow it to run containers and then genrate the seccomp rules for the container based on the syscalls that the container actuall...

Have you wondered if a certain dataset can be used for OSM? What does it mean for a license to be “compatible” with OSM and ODbL? This talk will give pointers on where to look for information, common compatibility issues, and best practices for presenting a license to LWG for help review. The talk would go over tips for mappers to help them think through potential license issues for imports. The t...
