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

The scans themselves are (c) npemap.org.uk and licenced under this Creative Commons Attribution-NonCommercial Licence 2.5.

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

So as not to break applications expecting Sector postcodes in the API, there is a new API endpoint:

http://api1.nearby.org.uk/api/convert.php

API requests against this domain will give the position of the full postcode, and also reverse geocode (return you the nearest) full postcode!

- The Original URL for the API is still available – and will continue to be. I’ve also taken the opportunity to add a version number to the URL. It’s been 4 years since I created this API, and learnt lots in that time, so should be able to create a better version 2 When introduce that don’t want to break compatibility.

Of course the ‘Coordinate Convertor‘ is now using CodePoint Open too – the end of having to pay a commercial provider!

(sorry this has taken so long, OS Opendata was introduced at the beginning of the month!, its been a busy month)

Will take the opportunity to duplicate the copyright message:

As it serves as a useful thank you, for making this data available.

Geograph Google Earth Clusters

This works in a similar way to the Geograph SuperLayer, by showing coverage overview, and then zooming in to reveal more detail. The Geocubes layer has the advantage that the clusters work into a closer zoom, and updates to the geograph database make it into the layer within hours. The SuperLayer is slower updating (weeks), but navigating should be much quicker being as its based on KML regions.

You can view also a Google Maps based version of the layer, using the Geocubes API directly.

This is only version 0.1 – there is more to be done – including being able to filter the results based on words and contributor, but this is exciting enough on its own. Once done a bit of work on tidying up the code plan to release it so others can use the geocubes service to create their own layer like this Watch this space!

Then enter:

m.nearby.org.uk

into your mobile browser.

Very privative, only goes to the nearby location links service, and a few pages on geograph. But between them give access to a fair number of (UK esp) websites.

Disclaimer: Only tested on a Google Android phone so far. Doesn’t seem to pickup GPS position (yet). To be honest surprised not found something like this in the Android Market.

If works out will probably add direct links to other websites, and possibly make it configurable so can choose which sites to show

Such as plotting an altitude profile with gpsvisualizer.com***, 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

Thanks to Lordelph for the Javascript (but I notice that links to a version hosted here!)

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 heywhatsthat.com 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 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.

Anyway minutes before I went away I got a deluge of emails saying the site if offline? what?? It turns out my generic credit card had expired, and without warning (feck) the machine was switched off. But this was 12am so their phone lines where closed (billing at least) – so a hasty phone call on the move in the morning and with the new card details they said be back within a few hours – not ideal but the best could do. I carried on my merry way and didn’t think any more of it (my mistake!), but the real feck up was that yes they had re-enabled the machine, they just forgot to re enable it at the switch…

It appears to be back now after much international phone calls….

btw – feck isn’t considered a swear word in Éire, and when in Ireland, do as the Irish do. (which is use it a lot!)

Update: as an amendum to the above, it turns out that on wednesday (3 days after it was switched off) a letter did arrive at home stating that they intended to turn off the server unless payment was received – and that it would take three days to reactivate the server. Which is at least factual.

Following a post on the Maps help group, realised could update it with some other ways to use the KML (even non Google!)
