Bachelor’s thesis: Using OSM for location analyses of residential real estate projects – an extrinsic analysis of data quality
In his bachelor’s thesis, supervised by HeiGIT’s apl. Prof. Dr. Sven Lautenbach, Lars Reckhaus examined the suitability of OpenStreetMap (OSM) for location analyses in the context of residential real estate projects. Typically, such analyses require the use of a variety of data sources and are mostly performed manually. For this reason, they tend to be…

Introducing ohsomeNow stats: Real-Time Monitoring for OpenStreetMap Contributions
You can now monitor contributions to OpenStreetMap (OSM) in real time with ohsomeNow stats! We developed this new dashboard as part of our long-term cooperation with the Humanitarian OpenStreetMap Team (HOT), an international organization dedicated to humanitarian action and community development through open mapping. This dashboard replaces the Missing Maps Leaderboard with a comprehensive overview of…

OEV: Indicator Correlations (4/4)
After introducing the OSM Element Vectorisation Tool last week, we now want to show possible use cases and specific examples of what the tool can do. This third and last example will look at the correlations between indicators. The goal is to first assure that the indicators measure distinct data attributes and then search for interesting or…

OEV: Quantifying differences between imports (3/4)
After introducing the OSM Element Vectorisation Tool last week, we now want to show possible use cases and specific examples of what the tool can do. This second of three use cases (see use case 1) compares the data in the regions of Maribor, Slovenia and Ngaoundéré, Cameroon. Both regions are exceptionally well covered with land-use and land-cover information in OSM.…

OEV: Analysing attributes of remarkable elements (2/4)
After introducing the OSM Element Vectorisation Tool earlier this week, we now want to show possible use cases and specific examples of what the tool can do. This first of three use cases takes a closer look at the data in the region of Heidelberg, Germany. We will use the concept of archetypes to identify…

New Paper: Carbon Fluxes Related to Land Use and Land Cover Change in Baden-Württemberg
Featured Image: Figure 1. Total carbon fluxes related to LULCC in Baden-Württemberg between March 2018 and October 2019 (LaVerDi, OSMlanduse+), and March 2018 and March 2020 (OSMlanduse, OSMlanduse cleaned). The upper plot shows the relative difference of carbon fluxes [%] with respect to LULC transition and carbon flux attribution method. The carbon fluxes of method…
