Cooliris (formerly Piclens)

Classroom Flickr users might like to be reminded of the amazing Cooliris browser. The plugin (which works best in Firefox) adds a virtual 3D lightbox over your computer screen, over which images and video can be dragged and resized at will. It would be brilliant with an interactive whiteboard and is a really good way to find pictures, news stories and videos.

Imagine a lesson on waterfalls…

Launch Cooliris using the browser icon. Select ‘Flickr’ and type in ‘waterfall’…

Browse hundreds of photos (automatically selected by Flickr’s “relevance” algorithim - so they’ll be good ones!) Students choose the one they’d like to sketch.

Which turned out to be this one…

It’s difficult to do justice to the coolness of this application. Go to the Cooliris site and download it!

NASA World Wind for sea level change modelling

I haven’t used World Wind for a while because I found the Virtual Earth plugin essential and it didn’t work with the latest release. Thanks to the comments from Bull UK in this post, I have been able to upgrade to version 1.4 and enjoy some of the new features which include the 3D connexion plugin for my Space Navigator, the Virtual Earth plugin and lots of other enhancements which make the program even nicer to use.

I was interested in testing the Global Flood plugin for World Wind and am pleased to say that it worked very well, though not at the zoom level required for the lesson I describe here. When zooming in to street level the flood layer fills the screen regardless of the elevation of the terrain and the Google Earth option works rather better. However, if the object of the lesson is to look at the impacts of sea level change on a regional scale, then World Wind is an improvement on the Google Earth technique, and the level of flooding can be controlled by a simple slider. Observe the “flood of blood” invading the Gold Coast!

Panoramic images in Google Earth

Digital Urban have published their tutorial for creating immersive panoramas. I made the short video below. There’s lots of potential for the classroom.

3D panoramas for the whiteboard

2007 celebrations in 3D
Thanks to Ewan of Edu.blogs for this post about 3D panoramas of New Year celebrations around the globe. He is right that they make superb viewing on an interactive whiteboard. I got students to work out the locations of some of the images using visual clues. The Dubai example is particularly good. The large number of Asians in the crowd make a starting point for discussing the situation of immigrant labour in a country where 73.9% of the population in the 15-64 age group is non-national.

Panoramas for geography lessons

It all gets even better if you go to the Panoramas dk home page and start to explore. Try the drop down menu in the top right and prepare to be amazed by some of the potential. As a taster, have a look at this image of a weapon search in Rio de Janiero

One of my favourite sites, Digitally Distributed Environments, is at the forefront of this kind of technology. Dr Andy Smith has just published a 3D panorama of a suburban area. This is a brilliant settlement resource:

Panoramas inside Google Earth

Andy Smith of Digitally Distributed Environments has recently posted about a 3D panorama viewer for Google Earth that his team is developing.

globe

Essentially the viewer allows you to fly into the 3D image which hovers above the actual location. There is a video that demonstrates the concept on the Digital Urban site and the viewer should be ready soon. It’s amazing stuff and I’m really hoping that I can get it working in my classroom, especially as a Digital Urban Flickr group has been set up to host panoramic images. Until now virtual fieldwork has been kind of uninspiring. How about one of Brick Lane Andy?

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.

space navigator The SpaceNavigator from 3Dconnexion

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.

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

Live Local in 3D

I forgot to mention the news from earlier this week of an important update to Live Local (or is it Virtual Earth?) Downloading a small plug-in brings 3D enhancement, and in my part of the UK at least, the images are of far higher quality than Google Earth. Unsuprisingly, the plug-in only works with Internet Explorer 6/7. The interface is now remarkably similar to Google Earth:

This is a view of my house:

The site is fast and very easy to use, and sharing placemarks is very easy. I see this being used a lot in the classroom, where Google Earth is not available, or where the resolution is inadequate. Stefan Geens has posted a very helpful summary of the merits of Live Local / Virtual Earth 3D.
