The map is set with the Charente Maritime right in the centre. You can zoom in and out using the plus minus control and move around by moving the mouse whilst clicking and holding.
For street view just grab the little orange man, place him on the map near a road and you can take a tour of the area.
If when zooming in and out you lose your bearings just reload this page to reset.
To return to the map from street view, click the X in the top right corner of the map.
