Historic OS Maps in Google Earth

Monday, November 8th, 2010

Thanks to the people at, who have taken the Historic 1940s OS Maps available at, I hearby present:

Historic OS Map layer for Google Earth.

This loads up a layer of Historic New Popular Edition (mainly) maps, onto the 3D Google Earth globe. This is made possible because the original maps are over 50 years old and hence the Crown Copyright has expired.

The WMS service only includes (Most of) England and Wales, no Scotland.

The scans themselves are (c) and licenced under thisĀ Creative Commons Attribution-NonCommercial Licence 2.5.

(Don’t forget to select the ‘OS Map’ layer, and drag the transparency slider!)

UK Onshore geology maps 1:50 000 scale in Google Earth

Sunday, January 3rd, 2010

The BGS recently publised the Geology of Britain website, which makes available a Geological map of Great Britain online in an interactive Map Viewer. They make available a 1:625 000 scale layer for Google Earth, and a the 1:50 000 scale version via WMS only.

Unfortunatly the WMS doesnt play nicely in Google Earth for some reason, so here is a hand tuned Google Earth layer to display the 1:50 000 scale Geological Maps:


Geocube Geograph Clusters in Google Earth – part 2

Wednesday, July 15th, 2009

Now ready with the next version of the Geograph Google Earth Clusters layer mentioned yesterday.

Google Earth Layer Geograph Google Earth Clusters

It’s the same download link, if you already have a copy, just right click and select Refresh on the “Geograph Google Earth Clusters” feature.

This has a number of advancements:

  • Filterable – click the main title in the Places panel to open configuration options in the popup balloon. Includes options to filter by keyword or Geograph contributor. (Requires Google Earth version 5)
  • Cubes/Cloud – Geocubes offers two clustering options, can how choose between then on the same popup as above
  • Thumbnails – Now shows a image thumbnail in the placemark balloons.
  • Shows a few coarse clusters when not zoomed on the British Isles
  • Source code available! Download the GPL licenced PHP source code here

But its not all rosey – this version seems to suffer from an annoying bug, when first loads sometimes the layer ‘freezes’ and doesnt automatically update as you move around. If that happens right click on the ‘Clusters’ feature in ‘Places’ and select Refresh, doing that once seems to fix it!

Thanks to Geocubes to the amazing service that powers this – highly recommended if you have larger numbers of features to display!

Multi Destination Routing + Altitude Profile

Friday, May 8th, 2009

There is a tool on nearby for taking a multi destination route – and loading it into Google Earth. It was also used to load directions into a “My Map”, but thats basically redundant now, but as the script just converts the directions to a KML file, there are many useful things that can be done with it…

Such as plotting an altitude profile with***, but to make it even easier, have added a button to the page, that links direct to the form on gpsu with the data prefilled as well as the ‘add altitude’ option enabled.

Enjoy! (Oh and let me know if there are any other interesting destinations would like to load the KML file into!)

Multi Destination Routing Toolkit

*** which Adam recently added the functionalty to add alitude automatically – previsoully a problem as the KML files from Google maps dont include altitude

My Maps Container

Wednesday, August 6th, 2008

When using the Google’s My Maps feature you can display multiple maps at once simply by ticking the boxes, however the ‘Link to this Map’ will only ever include 1 map, so you can’t easily send a group of maps to someone.

… So a new script – this time under the banner – for creating a ‘container’ KML that simply opens a bunch of maps at once – this KML is openabe in Google Earth, but also you can share the link so others can see your batch of My Maps at once in Google Maps.

Create a KML container for a group of My Maps

As a total aside I notice My Maps, now sport a (Geo)RSS feed :)

Google Earth 4.3: Magnetic Compass

Friday, August 1st, 2008

A while ago released a Compass Overlay, which (hopefully) makes reading directions of the navigation control easier. Well this new version does the same, but its (mostly) correct for the Magnetic Direction!

Magnetic Compass correct link this time!!

Note: its positioned to fit the navigation control of Google Earth 4.3, not the separate compass, which has only recently begun working for me… Updates a few seconds after stopping moving.

Now have a way to determine the magnetic variation at a location have some other ideas for using this in Google Earth, eg magnetic bearing along a line, but this is a starting point. For example in the uk the variation is often too small to be really seen on the tiny control.

Thanks to for the pointer to a webservice that gives the variation.

Update: Rather embarrassingly just noticed the link above was wrong! It was to a static compass. The link above has been updated, and it should now rotate! Sorry for confusion… (always wondered why this didnt get much traffic!)

Google Earth: Chart Plotter

Sunday, July 27th, 2008

Did someone mention a chart plotter? If so have a look-see:

Google Earth: Map Plotter

Its hot off the presses so don’t know what options it will need yet, just used three example zooms levels – other options would include the mobile map style. (You can change it by altering the link in Properties)

Also its standard Google Maps, as that is all the API offers. Ideally would be proper flight plan data, but would need a Static Map API to work.

Note: The map is centered on the camera position (so is ideal for the Flight Simulator) – and while it can be used in other modes it wont make much sense. If interest could make one that shows the center of the view itself.

Disclaimer: this is entering the gray area of what is possible with the Static Maps API, so might get pulled, etc.

More flight sim tools

Google Earth: Flight Simulator GPS Arrow

Saturday, July 26th, 2008

Behold a new network link from

Google Earth GPS

Once you have chosen a destination point, a small arrow will be shown in the bottom right of your Google Earth window, which points towards your destination! Ideal for use in the flight simulator, where you can play follow the arrow.

Note it only updates every 5 seconds, and comes with all sorts of disclaimers such as don’t use in life or death situations.

Howto: Save Directions to a MyMap (GoogleMaps)

Friday, May 23rd, 2008

Google Maps doesn’t include a method to save ‘Driving Directions’ easily into MyMaps. Fortunately they do include KML import/export for most features, so can export the route as KML then reimport it into a My Map.

I’ve moved the meat of this post to a Thread on the Google Maps Group, better for Google to be hosting it :)

Where in the world are people looking? part 2

Saturday, March 1st, 2008

Following part 1 yesterday, have now plotted some maps per individual service.

Flash Earth Layer


  1. Google Earth does request a link for the initial view on startup – that point in the Atlantic.
  2. I guess North American installs have two slightly different default placemarks; has it changed, or maybe Canada gets a different one?
  3. But that doesnt explain the lines from there – people must have their links set to periodically refresh?
  4. Germany likes FlashEarth (or rather people like looking at Germany with FlashEarth link enabled)
  5. Many people leave the links open even when not in use – e.g. the British Isles links show worldwide usage, notably over Russia.
  6. MGRS notably has high usage in two areas.
  7. The Far east likes to know what direction they facing.

Update: In a total forehead slapping momont realised these unprojected whole world images, are exactly what is used in GroundOverlays, so the the pages now include links to view the higher resolution images directly in Google Earth, duh!

Example: View In Google Earth (don’t forget to try adjusting the tranparency slider!) [Update, to fix broken link, sorry!]
