Overview of Overpass API Query Generator for OpenStreetMap

The Overpass API Query Generator for OpenStreetMap is a specialized tool designed to create precise Overpass QL (Query Language) queries. These queries extract specific geospatial data from the extensive OpenStreetMap (OSM) database. This tool is adept at handling a wide array of queries, including the extraction of data on buildings, natural features like hills, infrastructure such as bridges, and even complex spatial relationships, like proximity of certain features to others. The primary purpose of this tool is to facilitate users in accessing and manipulating OSM data effectively, tailored to their specific requirements. Powered by ChatGPT-4o

Core Functions of Overpass API Query Generator

  • Data Extraction for Specific Features

    Example Example

    [out:json][bbox:{{bbox}}];nwr["building"];(._;>;);out qt;

    Example Scenario

    Used to extract data of all buildings in a specified bounding box area.

  • Queries Involving Spatial Relationships

    Example Example

    [out:json][bbox:{{bbox}}];nwr["building"]->.buildings;nwr["waterway"]->.waterways;nwr.buildings(around.waterways:300);(._;>;);out qt;

    Example Scenario

    Helpful for urban planners to find buildings within a 300m radius of rivers.

  • Exclusionary Searches

    Example Example
