# GeoJSON Reprojected

geojson, bing, projection
Display GeoJSON data over Bing tiles

This example demonstrates the use of GeoJSON over Bing tiles. The GeoJSON vector data is in geographic coordinates (EPSG:4326). The Bing tiles are in a spherical mercator projection (EPSG:900913). By setting the `projection` property of the GeoJSON layer to the source projection (EPSG:4326), the features are properly displayed over the base layer. In general, the map projection determines how raster or vector data is displayed. The layer projection corresponds to the projection of the data source.

See the geojson-reprojected.js source for details on how this is done.
