Make queries toOpenStreetMap'soverpass API and output asGeoJSON.

install:

$ npm install -g query-overpass

use (Bash):

$echo'node(57.7,11.9,57.8,12.0)[amenity=bar];out;'| query-overpass

use (Windows cmd):

$echo node(57.7,11.9,57.8,12.0)[amenity=bar];out;| query-overpass

Optionally, a file containing the query can be passed as the first argument:

$ query-overpass query.ql

Goes well together with other command line tools, like for examplegeojsonio-cli:

$ npm install -g geojsonio-cli$echo'node(57.7,11.9,57.8,12.0)[amenity=bar];out;'| query-overpass| geojsonio

You can also provide the URL where the Overpass API is located:

$ query-overpass --overpass-url http://my.overpass-provider.org/

The default is to usehttps://overpass-api.de/api/interpreter.

You can also flatten each GeoJSON feature, making it more easily processable by other software and tools

$ query-overpass --flat-properties

The default behaviour, without adding--flat-properties is to usefalse to be consistent with previous version.

Installation is easy with npm:

$ npm install query-overpass

query-overpass exports a single function:

Performs the provided query and calls the callback when done. The callback is of the form

callback(error,data)

Where error is an object containingmessage andstatusCode if an error occured, orundefined ifno error occured.data will be the query response as an GeoJSON object.

The options supported at the moment are

• overpassUrl, which will default to'https://overpass-api.de/api/interpreter' unless specified.
• flatProperties which will default tofalse.
