02Agent OSM Downloader
QGIS 3.28+ and QGIS 4 OpenStreetMap acquisition studio with 30 curated presets, named-place resolution, structured multi-tag queries, safe Processing endpoints and bounded temporary outputs.
02Agent OSM Downloader is a stable QGIS 3.28+ and QGIS 4 acquisition studio for OpenStreetMap. Its 15 thematic groups and 30 curated presets cover urban context, street and rail networks, morphology, buildings, land use, green-blue systems, public transport, religion, tourism, heritage, sport, cycling, cars, traffic, healthcare, education, emergency services and administrative places. Urban Context connects street network, built form, trees, public transport and public-realm datasets, and datasets within a theme can be combined in one bounded request.
The four-tab dock provides Presets, Query, Command and Agent workflows. The English Command panel resolves dataset requests and named administrative places through pinned Overpass mirrors. A standard OpenStreetMap XYZ basemap can be added from the dock, while downloaded line layers can use OSM highway categories for distinct widths or one uniform width. The structured advanced-query panel combines up to four validated OSM tags with ANY or ALL matching, selectable geometry scope, examples, key/value suggestions and a read-only Overpass preview.
Sixteen persistent map styles provide live palette previews and native categorized QGIS renderers for buildings, roads, rail, transit, water, green space, trees and common points of interest. Agent Protocol v1 exposes four stable QGIS Processing endpoints that SmartModeler GIS can discover, inspect and run only after a validated proposal and explicit user approval. API keys remain in SmartModeler's process memory or encrypted QGIS vault and are never copied into this plugin.
Downloads use the current map or active-layer extent, three pinned Overpass mirrors with diagnostic failover, strict area, response and feature limits, cancellation, session caching and temporary point, line and polygon outputs. The plugin accepts no editable raw Overpass query, arbitrary URL, user path, API key or pip dependency. Online User Manual and Documentation: https://yusufeminoglu.github.io/02Agent-OSM-Downloader/
