Map legend: The map has a list of layers which can be switched on and off.
Clicking on the name will drop down the box to show the map file and show a preview as to how it looks. Putting a tick in the box will switch that layer on. You can also fade the map layer by clicking on the icon next to the tick box.
Move the scale bar between making it fully opaque (100%) or transparent (0%). Some tick box layers have more than one map layer within them.
Click on the name for the individual layers and their icons to be revealed. You can select any combination of layers you like by ticking the individual boxes. Above the Map Legend are the base maps. You can select between the colour map and the greyscale map. Click on the current base map name to reveal the both choices.
Select the base map you wish and the map screen will adjust accordingly.
Navigation: To move around the map, just click on the map and drag it around.
The pan tool can also be used. Click on one of the arrows to move the map a set distance towards the east, north, west or south. Clicking in the centre of the tool will return the map to the initial view when first launched. To zoom in, either use the wheel on your mouse, rolling forwards to zoom in and backwards to zoom out.
The zoom bar can also be used. Click on the plus at the top to zoom in or click on the minus at the bottom to zoom out. You can also drag the marker up or down the scale to zoom in or out. As you zoom in, different scales of Ordnance Survey map are used to display information at the best scale for each zoom level. Cursor location:
Wherever the cursor is on the map, the precise grid reference is displayed on the bottom right of the screen. Scale bar:
At the base of the screen is the scale bar. This alters as you zoom in and out so that you always have a measured distance appropriate for the scale you are at. Move map to grid reference:
To view your current coordinates click the “Map Centre” tool:
This allows you to move the map to a specified grid reference or longitude/latitude. If accessing the maps from a GPS enabled device, click on the crosshair and the map will zoom to your current location.
Address search:
The address search box is in the top left of the screen. You can type in a variety of pieces of information to find an address: Postcode – full or partial, capital letters and spaces are not necessary. Building name or number Street name Town name The more information you have, the more accurate the results will be.
Type in a postcode, and a few sample addresses from that postcode will be displayed. To see the full list you must then click “Search”.
The search results are displayed on the left hand side. Click on one of the addresses for the map to zoom to that location.
The address location is displayed on the screen. Both a grid reference and a longitude/latitude are displayed for this location.
Find My Nearest: To see the nearest services to this location, you can select from one of the categories displayed. Once you click on a category, you will then see the map layers for particular services available within that category:
Click on a service to select it, and the map will zoom out to the extent of the nearest services:
The results are also listed on the left hand side. The nearest locations are at the top, with the distances given being “as the crow flies” measurements. If you hover over one of the locations on the left then the corresponding icon on the map with be highlighted, and vice versa. If you click on one of the icons on the map, then an information bubble will appear and will contain some information e.g. a weblink to that service:

When you want to start measuring, click on the map and then drag the cursor to the end point. To draw around bends, then just keep clicking along the length and change direction to navigate around. You will see a blue line being drawn:
To finish the measurement, simply double-click. The results are then displayed in the top right:
The default units are metres, but you can alter it to either feet, yards, kilometres or miles by clicking on the drop down box and selecting the unit you want. To measure an area, click on the Measure Area tool. As before, a blue dot will follow the cursor till you are ready to begin measuring. Click once to start measuring. Then click around the edge of the area and a blue polygon will be drawn:
Once you have drawn right around the area, double click and the results will be displayed in the top right:
Both the perimeter and area will be displayed, with metres being the default unit. To see the results in other units such as feet, yards, kilometres, miles, acres or hectares, click on the drop down box and select the unit you want.
Printing: A print can be made at any point by clicking on the Print tool in the top right:
When you are ready to print, click on the button and the print settings will appear:
