OpenStreetMap
An open-source collaborative world mapping project that provides freely available and editable geographic data and map tile services, using the Web Mercator projection standard.
Core Facts
Timeline (last 90 days)
In the Mainz Neustadt district in Germany, OpenStreetMap has mapped 431 benches, and the app uses this data to plan multiple circular routes of 590 meters, 987 meters, and 1294 meters, with the longest unseated segment being only 149 meters.
In the Kalighat-Hazra area of Kolkata, India, the number of seating locations recorded in OpenStreetMap is zero.
The Overpass API is a read-only interface for data queries in the OpenStreetMap ecosystem, supporting the filtering and extraction of geographic features in specific areas through SQL-like syntax with conditional criteria.
TerraGemma uses folium and streamlit-folium to render OpenStreetMap layers.
A developer scraped data from two Indian cities approximately 300 km apart and found: the smaller city had 28 locations, 0 benches, and 3 tagged trees within 1200 m; the larger city had 701 locations, 24 benches, and 566 tagged trees.
OSM data reflects where annotators live rather than the actual distribution of features, creating a structural bias in the geographic availability of applications built on OSM.
card_writer requires the model to wrap each place name in double brackets, which are then extracted via regex and compared against a real OSM place name list to check for hallucinations.
The OSM community currently has no unified rules for handling sensitive annotations; some contributors prefer to mark only the outlines of facilities without adding functional descriptions, in an attempt to balance information transparency against the risk of potential misuse.
The quality of OSM layer data related to North Korea is uneven: data on the urban area of Pyongyang is relatively more complete, but road network annotations in rural border areas are rough and have higher error rates.
The OSM community typically organizes dedicated "Mapathon" events for high-risk or hard-to-access areas, concentrating volunteers to batch-annotate in order to improve data coverage and consistency.
