02AgentOSM - OpenStreetMap Downloader
Download OpenStreetMap (OSM) data into QGIS and extract roads, buildings, the street network, schools, hospitals, parks, transit and more for the map view, a named place, a drawn box or a radius, as styled layers or a GeoPackage.
Open the dock, search a town under Named place (or zoom the map to your area), tick a dataset such as Buildings or Road network and press Download. Styled point, line and polygon layers are added to the map, each recording the OpenStreetMap attribution and the date of its data.
44 ready-made datasets in 16 topics cover the street network, buildings, land use, parks and water, public transport, cycling, schools, hospitals, heritage, administrative boundaries and everyday amenities for 15-minute city studies; tick several in a topic to get them in one download. Any OSM tag can be requested, and the Query tab combines up to six tags with ANY/ALL matching, regular expressions and an exclusion. The area can be the map view, the active layer, a named place (inside its mapped boundary when it has one), the bounding box of the selected features, a rectangle you draw or a radius around a point. Areas over 100 km² are downloaded in parts, up to 2,500 km² per download, and a part the servers find too dense is split into smaller ones. When some parts cannot be fetched, the plugin says "Finished with gaps" and Continue fetches only those once the servers are ready. A short request in English or Turkish, such as "parks in Konak", fills in the form.
Results stay as temporary layers or go into a GeoPackage that stores the style, the attribution and the data date. Typed columns (height_m, levels_n, lanes_n, maxspd_kmh, width_m, pop_n, length_m, area_m2) sit beside the OSM tags, and 17 map styles restyle the layers live.
Servers: downloads use overpass.private.coffee and overpass-api.de, one request at a time and at most 64 per download, and rest a server that is busy or asks to slow down. If both fail or are resting for a part of the area, that part can come from Geofabrik's Postpass at postpass.geofabrik.de (optional, off by default; turn it on in the dock or with ALLOW_FALLBACK). Place searches go to nominatim.openstreetmap.org, and the optional basemap loads tiles from tile.openstreetmap.org. Answers are kept in a local cache for an hour, or a day for the parts of a download with gaps. Commands are interpreted on your computer.
Agent Protocol v1 offers four Processing endpoints, three of which 02SmartModeler runs after a validated proposal and your approval.
