Views GeoJSON

Views GeoJSON is a Views plugin for outputting geospatial data as GeoJSON, a JSON-based text format for encoding a variety of geographic data structures.

Features

• Generates GeoJSON data feeds from content using Views.
• Accepts data in latitude/longitude, Geofield, or WKT formats.
• Works with OpenLayers and Leaflet modules.
• Accepts a bounding-box argument to filter points by those within given coordinates.

Basic usage:

1. Create a View ("Show: Content") that includes geospatial data in its fields
2. Add a Display to the View with Format: GeoJSON Feed
3. Add fields to the Display that include lat/lon, Geofield, Geolocation, or WKT data
4. Set the Display's Format to GeoJSON
5. Set those fields as the "Map Data Sources" under "Format > Settings"

The view's output will be textual JSON, including data as GeoJSON Features wrapped in a FeatureCollection.

Origins

This module was born from a patch by tmcw to the OpenLayers module: Implement GeoJSON output as a standard, and a good deal of the original Drupal 7 version was modeled after the Views Datasource module.
