The brilliant online utlility, GPS Visualizer, now offers a network link for Google Earth that once refreshed, allows you to download alternative background satellite data for the area being viewed, as a KMZ overlay. The link works out which data sets are available for the particular location. I’ve already used it to find an alternative landsat image for a case study that I’m working on.

The screenshot shows the range of satellite data available for the selected location in the Places folder, with the “Terra” daily 250m overlay loaded in the main viewing window.
Thanks to Ogle Earth (as usual!)
Last week I spontaneously decided that it would be a good idea to film some students talking about their homework. I recorded the video on my mobile phone and converted the file into .avi format using Xilisoft 3GP video converter.
Subsequently, I’ve felt that this is a really good way of assessing work. Because the students themselves aren’t in the frame (an important point), they focus on describing their homework. Their understanding is evident, and a collection of short videos like these may be a useful tool when demonstating their progess to a sceptical Ofsted inspector.
I got some Year 10 students to talk about the Year 7’s work today and filmed them in the same way. There were two reasons. Firstly I thought it would be an interesting form of assessment for learning, because the Year 7 students would be able to see how other pupils interpreted their work, and consequently how to improve it. Year 10s got the opportunity to revise some of their work on settlement.
I’ve briefly edited the videos in Windows Movie Maker and the results are available to download below:
Year 7 talk about their work (9.4mb wmv)
Year 10 talk about Year 7 work (4.1mb wmv)
The files play in Windows Media Player, and because of the limitations of the recording device, you may need to turn up the sound on your speakers.
Thanks to Ogle Earth for this post about a new tool for Google Earth.
ITag is a free application that lets you add locational information to your photographs using Google Earth.
Simply drag pictures into the application’s main window and geocode them by dropping a Google Earth placemark over them. It’s remarkably quick and simple, and there is the option to add the Flickr Fly script that I’ve previously mentioned, so that once the photograph is posted to Flickr, it’s possible to open it up directly in Google Earth from within Flickr.
This file can be shared easily, and an example is posted below:

Thanks a lot folks!
I thought I’d post a Google Earth placemark created by Year 8 students as part of my lesson for visualizing a safer San Francisco. The placemark locates a suitable site for a new hospital. See previous post

Lots of placemarks were created by the class, and a peer assessment exercise selected this one as the best overall site. I was impressed by the detail, and the way the students selected information from the standard Google Earth layers as well as the overlay information provided. The students also make links to previous learning.
