Demonstration of World Wind

This is a transcript of a QuickTime movie (18.8 MB) recorded at the Macquarie ICT Innovations Centre in 2006 when Carol Oliver, from the Australian Centre for Astrobiology, demonstrated one of the virtual field trip tools, World Wind, for high school students.


You’ll find it’s a free floating planet. You can move it in any direction just holding down the left hand side of your mouse, okay? You don’t have to try and remember this, just exploring with your mouse, you’ll find which one actually works, okay? I know that you young people are very good at working out how things work

So I’m going to take you into an area of the western United States, actually into Washington State and I’m going to take you to Mount St Helen now actually it’s a volcano. You can see it blew out its side some years ago. And what you can do with this is this, by holding down the right hand side of your mouse. So you can have lots of fun with these tools, okay? All right? You can also, that is we’re looking at this full Landsat data, okay? All right? So you can also try these and sort of look at it in different colours. Well I won’t wait for it to come up but when you, you see across there you can see, or maybe you can’t, here, green. That tells us more information is coming in. If it’s red, well the red tells you there’s more information coming in, sorry. The green tells you that there’s more information to be got, okay?

But when you try out these ones, the one thing you have to remember is to click it off before you go on to the next one, all right? If you open multiple ones, it’s not going to respond to you, all right? The next version of World Wind will get over that problem but you have to remember to click off as you go through each one, all right? But you’ll see there are other ones, Geocover there, and when you’re in the US you can look at the one metre resolution. That’s one metre per pixel, okay? You can look at topographical maps. You can look at the urban maps in the US, which gets you down to looking at cars in the street and into people’s backyards. You can go to the Astrobiology Field Guide and I’ll go back to that in a moment. You’ll find boundaries and place names. You can explore all of these at will, okay, Modis data, cloud data. The cloud data, by the way, is updated but it doesn’t move. Place finder you’ll find. You’ll see a compass so you can put compass direction in the bottom there. You can put latitude and longitude lines on. Come right out and see the latitude and longitude lines. Oh by the way the other thing is if you make it disappear below, down at the bottom of the screen and you can’t make it come back up, just reload it. It takes a bit of practice to get it back. You can also put on headings, they’re over there, see, like that. So you watch these move as I move, all right? You can read off the latitude and longitude.

So what I’m going to do before I let you go and have a go at this, you see it’s cloudy in Western Australia today, is I’m going to take you into Western Australia. And the way to look for the Pilbara is to turn on that Astrobiology Guide. See the little icon there. You’re sure it’s that one because you go in there and it says Pilbara, okay? You can go in and actually that icon is a little bit in the wrong place, we need to fix that. Just go down the river, this is the Shaw River, and you’ll come to this bend in the river here, okay? And as you see, it’s quite clearly different there from the rest of the countryside. Just go in there and actually the Trendall locality that we were looking at in the presentation is actually there, either side. That’s North Shaw and on the other side is the Trendall locality. And again, you can do this, the same thing, okay? But the interesting thing about this is I want to show you layers.

If you go into the Layer Manager and you go to Zoomit, okay, I know this is going to be all too much for you to remember but you just go exploring, and pick the one for Australia and you’ll see you can get other maps. This one I’ve asked for is the geology map and you can still move it around, all right? So you can explore that.

Ok, that’s our planet but before you go I just want to show you one of the other ones. You can explore all of the other ones down on this list and I want to show you Mars. Again it shows you the Layer Manager. It gives you another opportunity to understand that Layer Manager. You’ve got this kind of thing. I’m going to take off latitude and longitude lines so you can see it. So you can do exactly the same thing as with the Earth. I’m just going to go into Layer Manager, you can actually use this image that is up at the moment but I actually don’t like it so we’ll go to Images and because I don’t like it I’m going to actually take off the data and we’re going to go down to this one here, Themis color data. And there are two interesting areas really to just explore in here. This big gash you see here is actually Valles Marineris and it’s really the Grand Canyon on steroids. If it was stretched, if it was here on Earth it would stretch from Sydney all the way to Perth so it’s huge. Now, your question?

Can you get to the Moon?

Yes, you can get the Moon. The Moon is there so I’ll let you explore that by yourself, all right? By the way, you’ll see that, no wait a minute, before you go, when you get to it you’ll find some strips with missing data. That’s because it’s satellite data not because of imaging problems, all right?

Now let me just take you into Olympus Mons, the largest volcano in the solar system and you can see you can get right into the caldera and we can do this, okay? Move out and then I’ll just tilt it around to show you what you might be, you see there’s lots of missing data there, you see all those, that stuff there. But there is that Grand Canyon on steroids, we’ll just go in there and, it looks a bit of a mess doesn’t it, but then you turn it on its side and you fly down it, all right?
