You're all set!

To start developing, please head over to our developer documentation.

Activate the Google Maps JavaScript API

To get you started we'll guide you through the Google Developers Console to do a few things first:

  1. Create or choose a project
  2. Activate the Google Maps JavaScript API and related services
  3. Create appropriate keys

Basic map types

 * This demo demonstrates how to replace default map tiles with custom imagery.
 * In this case, the CoordMapType displays gray tiles annotated with the tile
 * coordinates.

 * Try panning and zooming the map to see how the coordinates change.
