Using online maps for grid refs

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I used to use the OS Get-a-map (http://getamap.ordnancesurvey.co.uk/getamap/frames.htm) for getting grid references, but I've got a bit frustrated with it for various reasons. 

I've recently been fiddling with Google maps and have written a web page that lets you get a grid reference by right-clicking on the map; you can also jump to a typed-in grid ref or a named location:

I'd be interested in any feedback on this, I'm already finding it useful for myself.

Some other people have already done similar pages:

http://maps.google.co.uk/maps/mapplets?moduleurl=www.nearby.org.uk/google/gridref_mapplet.xml

http://googlemaps.record-lrc.co.uk/

I'm sure there are others, does anyone here have recommendations?

	I gave up using Get-a-map some time ago as it took too long and was so cumbersome to get a grid reference. I use Keith Balmer's "Grab a grid reference" page he developed for Bedfordshire Natural History Society. There's two versions either mono where you have to toggle between aerial & Google map windows http:////www.bnhs.co.uk/focuson/grabagridref/html/mono.htm or the duo version where there is an OS map frame next to the aerial & Google map frame on the screen. http://www.bnhs.co.uk/focuson/grabagridref/html/index.htm It determines grid refs as eastings and northings, or for a 10m square, 100m, 1km or 2km square. There is a limit to the number of views the OS allow per day. This also applies to another useful website "Where's the path" which has OS map and aerial views side by side and the position of the cursor is given as a grid reference and latitude & longitude. It is useful in that you can also use the path tool to measure distances - or if the aerial photos are detailed enough to work out the dimensions of ponds, etc. http://wtp2.appspot.com/wheresthepath.htm Edited by Chris Monk - 18 May 2011 at 11:58pm

	The 'grab a grid reference' one is very good indeed, especially the duo version- I might give up on mine, and just use that one!
