360 panoramas on Juicy Geography

My recent 360 degree panoramic images with some degree of classroom potential have been added to a new page on Juicy Geography. Eventually they’ll be sorted out into categories and suggested teaching ideas added.
It has been incredibly expensive to buy the necessary equipment to make these images. I wonder if the donation button will get any response? It is easy to remove the embed option – which I will if they start appearing on other web sites!

It’s been an ambition of mine to create my own immersive VR panoramas ever since I first came across the 360 Cities website. After saving up for a decent camera, lens and the requisite tripod technology, I’m finally up and running. I bulked at the cost of stitiching software though, and while I really liked PTgui and would love a copy of Autodesk Stitcher I can’t afford them. Fortunately, Hugin is free, Open Source and totally brilliant. I also use Cubic Converter to extract cube faces from the equirectangular images in order to clone out the tripod.

There’s so much to learn about this form of photography; it’s not quite as easy as I had imagined. Here’s one of the first images I’ve produced:

The Nave, Wells Cathedral in England

I’m planning to create a series of images specifically for classroom use. These will eventually be available on Juicy Geography. An example is this image of a brown-field site:

Morlands, Glastonbury in England

I notice that if you right click on the image you can choose different projections. This one works quite well as a “little planet”

Please get in touch if you have suggestions for a panorama for the geography classroom. And if you do use one, why not help me to recoup the massive financial investment by donating to the site development of  Juicy Geography?

Spherical panorama QTVR project

To celebrate the reconnection of my broadband which had been off for two days I’ve uploaded my very first attempt at a spherical panorama. I’m using a trial version of stitching software, hence the logos for ptgui everywhere. Lacking the funds for a proper pano-head and tripod leveller, both of which are fairly essential pieces of kit, I’m using a combination of tripod and a plumb line suspeneded from the nodal point of my lens to a compass rose on the floor in order reduce parallax errors. It’s really time consuming and fiddly, taking several minutes to shoot the 10 images required to assemble the final panorama.

The image is of my favourite bouldering spot on Dartmoor – Black Hill. I managed a couple of v4 6b problems here yesterday, despite being fat and weak after months of sitting at the computer. A better version is now on 360 cities.net, but it’s technically unpublished.

Message to my sponsors!
I’ve been saving up for the equipment to make a series of these panoramas for the benefit of the geography education community (to supplement those on 360 cities.net). I’ve recently brought a new camera and a very expensive fisheye lens but the rest of the hardware and software is out of my reach at the moment. If any company or professional organization wants to make a contribution to get my QTVR project off the ground, then please get in touch. All the images I produce will be published on 360 cities for the benefit of the whole community, however it could be possible to add a small corporate logo to the finished images, as well as an advert link from Juicy Geography which will eventually have a dedicated QTVR page.

Animated prism map in Google Earth and EarthBrowser site tracker

Here’s a quick mention of Thematic Mapping blog in which Bjørn Sandvik describes a number of data visualization techniques using Google Earth. Since I’m teaching about the Green Revolution tomorrow, I wanted to find a suitable animation to impress the class. A Google search led me to Bjorn’s blog and a kml file on the human population explosion that was perfect for my needs. The file can be found on this page, and is illustrated in the video:

Animation of SE Asia population growth in Google Earth from Noel Jenkins on Vimeo.

I’m sure that many other geographers will find the population animation (and many of the other resources at Thematic Mapping) very useful.

Another discovery on Thematic Mapping, was Matt Giger’s EarthBrowser site tracker. I love EarthBrowser and was interested in this embeddable version. I tried it out but found that it currently seems to prevent Safari from scrolling properly.
