Here you can choose where you want to view, and at what scale you wish you to do so.
The scale bar contains ten buttons, eight of which are fixed zoom levels and the the remaining two allow you to zoom in or out to the next or previous level.
Around the main map are eight arrows that allow you to pan around the map in order to find the location you wish to view once you have begun to zoom in to a larger scale. You can also click anywhere on the main map to centre that area in the map view.
The overview map in the top-left corner allows you to centre the main map on wherever you choose. You can do this by simply clicking on the overview map when you have begun to zoom in to a larger scale.
The main map also allows you to zoom in to a larger scale by clicking and holding the mouse button, then dragging the mouse over the image. This draws a box in the image, which shows you the region that will be shown in the new map view. This automatically selects an appropriate scale and redraws the map view for you.
After checking the "Find Policies" checkbox, clicking on the map, in any location, will display a list of related policy numbers allowing you to read the accompanying documentation for those policies.
Here you can choose which policies should be displayed on the main map. This is done by checking or unchecking the checkboxes next to the relevant description in the legend, and then clicking on "Update Map". This will reload the map showing the same region as before, but with the new policy display preferences.
You can also click on the "Check All" and "Uncheck All" links to display all or none of the policies respectively.
Hovering your mouse over the descriptions within the legend will display a tooltip showing any policy numbers related to the described item.
