The SpaceNavigator

Over the past few weeks, a small round UFO-like object emitting a blue glow has sat on my desk. Coincidently that’s the same amount of time that I haven’t been using a mouse to interact with Google Earth.

The SpaceNavigator is a 3d input device that provides a delightful way of interfacing with Google Earth. A gentle press on the top results in a smooth gliding descent towards the ground. Equally intuitive hand motions allow the user to navigate within the virtual globe, and after a couple of sessions my mouse was confined entirely to essential clicking operations.

It’s a lovely object, comprising a heavy stainless steel base and a stumpy joystick surounded by a blue LED. The SpaceNavigator experience is somewhat addictive, and on reflection, I’ve spent a lot more time in the past few weeks exploring the earth purely out of interest, rather than an urgent desire to find a crucial placemark in time for a lesson the following day. Certain operations, for example flying around a mountain or valley feature, or following a route through a 3D city are considerably enhanced with the SpaceNavigator, since you just keep watching the screen as your hand does the navigating. By comparison, a mouse now feels clunky, especially when tilting the view.

Setting up the SpaceNavigator for initial use was straightforward, with a well constructed tutorial part of the software. It plugs in to the PC via a USB port and the driver installed with ease. The joystick and two buttons can be customized via a control button and preferences saved for different applications. (I found that I was happier with most of the controls reversed.)

I’d love one of these in my classroom, in fact now the device has officially launched, that’s where it will be heading, albeit somewhat reluctantly, since I’m extremely attached to it! Younger test subjects (i.e. my 12 year old daughter and friends) have responded with huge enthusiasm. A particular benefit of the device is that navigation is generally a lot smoother than with a mouse, and video captures are therefore improved. I envisage students recording in-flight commentaries for Google Earth videos as part of future lessons. The SpaceNavigator works with many other 3D applications including SketchUp.

I’m very happy to recommend the SpaceNavigator to teachers and students alike. The Personal Edition will cost £39.00 inclusive of VAT in the UK. This version is licensed for non-commercial and educational use, and is functionally identical to the Standard Edition (£69.00) The 3Dconnexion web site has more information on the device, and a list of re-sellers.
I turned down an initial invitation to travel to London for an early preview, because cynicism and inertia outweighed my interest in the product when it was first described to me. 3Dconnexion sent me a device to try, with no obligations to write a review. I wouldn’t part with it now!

Update:
Ogle Earth and Google Earth Blog have detailed Space Navigator reviews out today. Ogle Earth also has a short interview with Rory Dooley from 3d connexion and Frank Taylor has posted a great video on You Tube. I’ll be updating my review once I’ve trialled the device in the classroom.

Peer vs Public assessment: Google Earth blogs and polls

With peer assessment a currently popular trend, I decided to add a twist and get members of the public to vote and comment on some Year 8 work.

It occurred to me that a basic web poll and blog comments would serve to give students useful feedback on their work. The assignment was based around my Google Earth San Francisco lesson. I’ve mentioned before that the ease with which Google Earth placemarks can be created and shared, makes them ideal for assessing spatially located geographical work.

Go here to my new Google Earth blog to find the poll and the students work. Download the work as a Google Earth file, together with the teaching materials, and vote for your favourite. Leaving a comment would provide the students with additional feedback. We would be particularly keen to hear from any residents of San Francisco!

The students and I would be very grateful for all feedback.

New blog for Juicy Geography

I’ve revised the Google Earth page at Juicy Geography with a fresh new look, revisions to the content, and a blog front end. This should make it easier to maintain the page, which had become to long and unwieldy.

Arc GIS Explorer news

A tempting preview of the long awaited new product from ESRI, ArcGis Explorer is available as a podcast. You’ll learn how to pronounce “ESRI” correctly, but more importantly the interview with a member of the development team offers an insight into the nature and scope of the new virtual globe. This page contains a showcase of ArcGIS Explorer’s potential.

The new product is not designed to compete directly with Google Earth and isn’t really a consumer product, but a platform to publish GIS data. It is powered by ArcGIS Server and should be regarded as a series of globes with worldwide data on a range of topics. The globes will be called ArcGIS Online Services and encompass a range of themes, for example worldwide streets, terrain and physiography and more. The new virtual globe will be free, though you’d the full Arc GIS product to create new content. It remains to be seen whether ArcGIS Explorer will be a useful classroom tool, though ESRI do actively promote the use of their products in schools.
According to the podcast, ArcGIS Explorer is on the point of being rolled out. Link to download site

Google Earth news

Two exciting new overlays to report.

Firstly, Maplecroft Maps have sent an email to their users announcing that a selection of their excellent maps are available for Google Earth. Great news as the screenshot of the world AIDS data shows:

Meanwhile Frank Taylor and Barry Hunter offer a network link to display the shiny Blue Marble imagery from NASA that dramatically improves the initial look of Google Earth. Added is a link to the near real-time global cloud data. This layer uses the new alttiude feature of Google Earth 4, so you can zoom in past the clouds on your way to the surface. Truly a great network link. Frank hopes that the Google team will implement an official version soon. It makes me slightly worried for the vast number of schools who are constrained by hardware to the older version of Google Earth. Hopefully Google won’t withdraw version 3 any time soon. Head immediately to Google Earth Blog for the network link!

A new blog is born.

A new blog has been set up for Somerset geography teachers. All welcome!
