Grab a Grid Reference...
The single map version of this tool is HERE
Show:    Bedfordshire    VC30     

Checking tile count...

Drag the red marker on the left map to where you want a National Grid reference (as defined on Page 35 of A Guide to Coordinate Systems in Great Britain)
(Although the National Grid covers a portion of Ireland Irish grid references are usually given using a different system. Irish grid refs can be obtained here)
The grid refs will appear on the right, and the corresponding boxes are drawn on both maps.
Please do not record using 2km or 10km grid refs. These are for information only.

On the left map press "Satellite" for aerial photos only, or "Map" for Google Maps only.
The Vice-counties, VC30, Bedfordshire and Accessible Wildlife Site boundaries only show on the left map (at present...)

The right map shows Ordnance Survey maps of different scales according to the zoom amount.
Ordnance Survey limits the number of map tiles accessed per day, so the right map will stop working if this is reached.

The right map tracks the left map whenever it is zoomed, panned or the marker moves, but the right map can be can be zoomed and panned on its own.
If you've found the place you wanted using the right map, you can move the left map to it using the "Match Left Map to Right Map" button.
The "Get The Marker" button moves it to the centre of the left map, so match the maps first.
The marker on the right map cannot be dragged.

The "Go to ..." box can be used to go to a Grid reference (e.g. TL123456), or a postcode e.g. (MK41 9DJ), or a place name. (Currently it goes to the first matched place name, but a choice will eventually be offered - bear with me).

The new "Toggle Vice-County" selector turns a Vice-County boundary on and off each time that county is selected. It takes a while to download to your PC some of the VCs, so you may see a delay before the boundary appears. Multiple VCs can be displayed. If you want to clear all the VCs, select the second option "Clear Vice-Counties". Clicking on a boundary will tell you which VC it is.

GAGR now fits to the browser's window size when started. If you subsequently change the browser window size you can re-fit the maps to it using the "Fit to Window" button. Please let me know if this causes you any problems and I'll have a rethink.

A location, along with all the display options other than selected Vice-Counties, can be bookmarked using the Bookmark button. If using Firefox you'll probably want to untick the "Load this bookmark in the sidebar" option in the dialogue box that pops up, otherwise the bookmark will open in the sidebar.

OS Vector Map District maps have been enabled at one zoom step between the 1:50,000 maps and OS StreetView, to provide an extra choice of map. I'm still getting used to how pale these are - I don't know why OS didn't make the colours bolder like the other levels of mapping...?

The "mono" map version of this tool can still be accessed HERE if you prefer it.
If you find this tool slow and jerky with Internet Explorer, try Firefox, or Chrome or Opera, which are all much smoother and faster on my PC.
Showing boundaries slows the map update process, considerably with Internet Explorer. Turn them off while moving and zooming the maps if you find this to be a problem. Boundary names can be found by clicking on them (unless using IE).
