Tom Barrett has mentioned on Twitter the welcome return of OS Maps in Google Earth. The network link is available at Gavin Brock’s Ordnance Survey overlays for Google Earth.
This is really great news – the  link effectively renders digital maps like Memory Map and Anquet somewhat obsolete, since the OS maps can be draped over 3D terrain. There is a catch though – like the brilliant side by side mapping website Where’s The Path? the link is subject to a limit of 30,000 map tiles per day. Frustrated users are directed to the Free Our Data campaign. Where’s the Path? is so popular that it’s often unavailable in the afternoon.

I’ve been using a couple of useful mapping apps on my iPhone. The useless battery makes it very limited as a navigation device. However if you’re out with a paper map and lost, then GB Locate at 59p (iTunes) will give you an OS grid location with little fuss.

A second useful iPhone App is iOSMaps (iTunes) which provides Ordnance Survey Maps on the iPhone. It works well providing a wifi connection is available and it’s free to download.

Some brief updates and news…

Action Aid contacted me with news about an interesting free online resource called 20 Years of Chembakolli. More details below:

ActionAid has worked very closely with the tribal people of south India for many years, initially supporting them to fight for rights to their ancestral land, and in subsequent years in producing a range of Key Stage 2 resources for UK primary schools. The QCA even built up a scheme of work around ‘A village in India’ making explicit reference to our resources.


Join the March

We’ve launched a free online march to celebrate the 20th anniversary of the land rights marches that helped the Adivasis secure the rights to their land. The march allows teachers and pupils to join the march themselves and send a message of support to the Adivasis. It also allows them to explore the landscapes of Gudalur and, closer to the actual anniversary, the village of Chembakolli. They can click on buildings, objects and people to see photographs and learn more about life in south India.

Thanks to Adam Brewer who has contributed a really fun “Kung Fu” activity to Juicy Geography that is guaranteed to enliven the teaching of plate tectonics!

The Vendee Globe race is proving very popular among my Year 7, who won’t settle down until they’ve plotted their chosen skipper on their tracking maps. The Vendee Globe site hosts daily videos and podcasts and the key page for checking the current position of the boats is here. (Relating to a recent post)

Great news for 360 cities.net – their panoramic content now appears as a layer in Google Earth. Usually I rely on Google Earth blog for this kind of update, but I noticed it yesterday while running a Google Earth training course. I’m convinced it wasn’t there in the morning, but appeared just after I’d demonstrated the site to the participants. (related post)

Some iPhone news. The 2.2 update has arived. Lots of grumbling from some blogs that the update doesn’t feature cut and paste, Flash, voice guidance, toast making or world peace, however it does bring Street View to the platform. I’m finding my phone incredibly useful in the classroom, really just for the simple things – music, the decibel meter and the brilliantly simple stop watch for games such as Just a Minute. I use Maps, Evernote, Remember the Milk, Fizz Weather every day, and I still don’t care that the camera is useless and there’s no video. For the benefit of anyone accessing Digital Geography with an iPhone, I’ve installed the wpTouch plugin which renders the site super-efficiently like this:

Finally – it’s been two weeks since the very last malicious script was discovered and removed from my web server and no subsequent hacks – yay!

… and ran around school with it. The rest of the class watched live on the interactive whiteboard while demanding their turn.

We used My Moving Map for this activity (mentioned in a recent post), which was designed as a quick 5 minute demonstration of some of the differences between paper and digital maps.

there are notes in boxes that are empty
every room has an accessible history
every place has emotional attachments you can open and save
you can search for sadness in new york

The predictions of the HeadMap Manifesto (recently made available for downloading again) are becoming reality with the onset of location-aware mobile phones. I was recently directed to Woices.com by Mapperz and was really impressed by the concept of geolocated voices (the echosphere).

Here’s a Woice from my daughter. We’re going to complete a few more from this location. It’s a poem she wrote as an eight year-old visiting Race Track Playa. She left a copy in a kettle at TeaKettle junction!

More from Woices…

An echo is an audio record that is attached to a physical real-world location or object. Echoes are words, left by one person at some precise place, that can be listened to by anyone, as if their author was still there. Echoes can speak about any topic and respond to any user’s purpose. They can speak about local history, art, curiosities, personal memories, and so on. Just something you think its worth to leave that may make the world a more interesting place.
What is the echosphere?

The echosphere is the new virtual space spanned by all echoes left by people. Surrounding earth (and you), the echosphere contains all echoes and can be accessed through your computer or mobile phone.

The site implies that there will be an iPhone client on it’s way. There is a special mobile phone optimized page to access echoes quickly via an ecode. The ecode could be printed off and left at a real location for others to listen to – similar in concept to Yellow Arrow

UK teachers as usual, are very quick off the mark to spot the potential. Tom Barrett has written an inspiring post on how he intends to make Woices part of his digital storytelling project at his primary school. Tricia has created an example of a walk along the Thames. I’m going to use Woices next time I do a local enquiry.

I’ll update the post when we’ve completed our Death Valley walk.

Frank Taylor’s Google Earth blog once again scoops the official announcement from Google regarding the much anticipated release of Google Earth for the iPhone.

Google Earth on the iPhone

Google Earth on the iPhone

I’ve just been testing it, and OMG as my daughter frequently proclaims! The interface is incredibly intuitive. The search box also brought up my contacts list, so the first place I visited was my parents house…



The iPhone’s GPS quickly found my location in Google Earth, one obvious advantage over the normal platform.

Panning and zooming is simple – a combination of finger taps and movements. Tilting the phone also tilts the view. 3D terrain works!  The developers have also made use of the iPhone’s landscape orientation enabling a wider view. Here’s Snowdon in it’s new, high resolution imagery.

Finally, the Panoramio and Wikipedia layers are available, as are the borders and places layers from the parent application.



This is brilliant news. Walking out of my house and away from my wifi link slowed everything right down so I won’t be seeing myself in real time scrambling over Crib Coch. On the next upgrade I wonder if we’ll see the ability to add placemarks?

Update: Google Earth help notes / Ogle Earth’s rather more considered review!

iPhone GPS and the ideal classroom hand-held learning tool

 Google Earth, GPS, ICT, mobile, Neogeography, Photographs  Comments Off on iPhone GPS and the ideal classroom hand-held learning tool
Oct 262008

The aim of this review is to compare four different GPS applications for the iPhone. I selected them on the basis of generally positive reviews in the App Store, potential as an educational tool, and value for money. Over the course of preparing this piece, I had the opportunity to reflect on the perfect neo-geography iPhone application, and the ideal handheld learning device…

The applications on test are..

The applications on test

Each application was tested on a short bike ride around my block. I live in a rural part of the South West and phone reception is patchy – though actually O2 is the only carrier that works properly in my area. There’s no wifi or 3G reception and part of my route takes me through a GPS blackspot consisting of a lane with high banks and overhung with trees. I recorded a track and then uploaded it to the relevant web site. If the application permitted, I took  photographs and recorded waypoints.

The first application to be tested was My Moving Map website / iTunes

My Moving Map

This is a simple application that transmits your position to a website from which others can view your location, simply by entering your email address. It was extremely simple to set up and use. In operation, one merely taps the screen to broadcast the location of the device, which can also be seen on a Google map. The My Moving Map website not only offers a real-time map showing your location, that can be embedded in a blog (not WordPress I found) but also allows tracks to be downloaded as a csv file and KML for viewing in Google Earth. Here’s a map showing a recent walk during which My Moving Map constantly pinged my location.

Without the ability to create waypoints, the application is limited, but could be fun for certain classroom situations. You could envisage giving your phone to chosen students to go on various missions around the school while their progress is being tracked on the interactive white board. The application is is missing a software lock (necessary for all GPS applications on the iPhone) It didn’t seem to work well in my jacket pocket either. For what is does though this is a great application and well worth £1.19.

Next I tested RunKeeper. website / iTunes


RunKeeper is a free application and simply records a track that is uploaded to an excellent website where it can be viewed on a Google Map and speed evaluated against altitude. The RunKeeper site also logs your trips. The track data is very accurate, but there’s no export option which is a shame as it precludes the use of sites such as Magnalox and GPS Visualiser. A software lock works well.

RunKeeper is very highly recommended and I’ll be using it frequently. I’m not convinced that there’s much value to the geographical curriculum though for a collaboration with the PE department it would be excellent. Ollie Bray has also reviewed this application and seems to be impressed. It would be my first choice for monitoring runs and bike rides.

Next up was EveryTrail website / iTunes


This is a really useful application for geotagging photos. Just walk around and use the camera. At the end of the trip, upload the details to the EveryTrail website where it can be analyzed and viewed in a mumber of ways. The EveryTrail website is a popular resource among the geotagging community. See the details of my test here.

The GPS track was very accurate, the application has a software lock and is extremely easy and reliable to use.  The trail can be exported to Google Earth or as a GPX file. A great little application and definitely worth the £1.79. There is a real niche for this kind of application for fieldwork. I’d love to be able to add notes and recordings as well. The only other limitation is the notoriously poor iPhone camera!

Finally I looked at iTrail website / iTunes


I really wanted to like iTrail, having chosen to review it ahead of the more expensive GPS Kit. Like RunKeeper, iTrail is a tracking application; it’s USP is that it also records waypoints. In practice I found it difficult to use. iTrail crashed on several occasions, and I was unable to complete a journey without experiencing a problem. I’ve had several attempts, but each have ended up in frustration. The programmer mentions on his site that iTrail is in constant development, which is encouraging news. There are two modes – Quick Trail – which you’d use if you just wished to monitor a walk or run (though RunKeeper would be a free alternative). In Trail Mode you can add waypoints (though not photos). I found the lock button worked sporadically, more often than not resulting in the selection of Quick Mode, after which it was confusing to regain Trail Mode. The application crashed several times when entering waypoint information. I’d like to see the lock button moved to a different part of the screen, and a button to toggle between the modes. When it worked, the GPS track was accurate, and the program does give you an indication of GPS strength. A strong point is the ability to export KML and GPX data formats direct to a computer (rather than a third party web site) I’m going to watch out for updates to iTrail, though at the minute I wouldn’t rely on it. I’d like to think that out of the four applications, this one has the most potential for further development.

Summary of features:

Conclusion: The best GPS applications on the iPhone are the simplest. There’s little point in pretending that the iPhone, in it’s current incarnation could possibly replace a specialized GPS device for serious navigation or field studies. Poor battery life and cost are just two of the constraints. (Hence this is a rather futile post, despite the hours spent in preparation!)  However researching the post has helped me draw up a specification for the ideal neo-geography iPhone application which would…

Record a GPS track
Display a live view in Google Maps (similar to the free Maps app)
Have a screen lock and dimmer to preserve battery life
Create waypoints
Able to annotate waypoints with short written notes
Able to annotate waypoints with audio recordings
Add photos to waypoints
Geotag photos
Export in KML format and GPX format
Offer tools for analysis of performance, speed, altitude etc

I’m looking forward to seeing which developer gets there first!

Although I’m really conscious of the fact that I’m in the fortunate position of owning an iPhone (though it’s on PAYG) the era of widespread adoption of handheld devices as learning tools in schools is clearly arriving. I don’t think that the web-book type devices currently popular in some schools are quite mature enough yet for really immersive geographical fieldwork. However I’m sure that altruistic Apple developers are working away to create the ideal classroom computer, in the form of a slightly enlarged iPhone/tablet device featuring the same touchscreen interface, a better camera (and video recording) and a long life battery. The device would incorporate all the functions of the iPhone and also suport Flash, Google Docs, Google Earth and optimized versions of iWork and iLife. Not much to ask for…

Sep 192008

I can’t actually afford an iPhone however if / when I eventually acquire one, the first application I’ll install is Johan Nordberg’s Seismometer.

Seismometer records vibrations using iPhone’s built in accelerometer to “measure movements in two axes, calculate the resulting energy and draw the results on a rolling logarithmic scale.” There are many favourable reviews on the iTunes store and at 59p it’s somewhat cheaper than the classroom alternative.
In fact Seismometer would be perfect to use with my Shaker Maker – do it yourself earthquake table.

Other iPhone Apps that I’d like to try out include:


Earthscape is a virtual globe, though resolution outside the US is fairly poor. It’s currently available as a free download. (iTunes link)


GPS kit looks like an indispensible application to make the best use of the phones GPS. (iTunes link) It costs a few pounds though. I guess I just want to be able to replicate as many features of my Garmin Etrex as possible.

Aside from the three geography-related applications, I suppose I’d get some kind of Twitter client since my current phone is rubbish for that kind of thing. I also love the idea of the free WordPress application to be able to add and edit posts on my blogs rather more spontaneously than at present.
