Historical Real Estate Maps- LibraryHack Entry

I’ve submitted our second entry to this year’s LibraryHack competition – a PivotViewer collection of historical Queensland Estate maps. The application can be viewed here: http://rem.soulsolutions.com.au/.

Soul Solutions has taken the State Library of Queensland’s collection of digitized estate maps, advertising new housing estates in Queensland from the early to mid 20th Century. 165 of these have been digitized in the collection that can be found here: http://data.gov.au/dataset/real-estate-maps/

The maps are predominantly from Brisbane but also cover some regional areas of Queensland such as the Gold and Sunshine Coasts.

We have chosen to visualise these using an enhanced version of the Microsoft PivotViewer control, from LobsterPot Solutions, that allows us to presents 100’s of things at once and visualise them in a way that can add value by allowing multiple ways to filter and sort the collection and view details and metadata while showing the estate map image in a “zoomable” format.

Here’s a quick video demonstrating the application or you can watch it on YouTube here :http://www.youtube.com/watch?v=5RpauKnxp2w&feature=channel_video_title



Mosaic of Queensland – LibraryHack Entry

I’ve just submitted my entry for this year’s LibraryHack competition, a 10 Gigapixel Mosaic of Queensland made from 52,102 images from the State Library of Queensland.


View the full resolution version here.

Currently the full resolution version is only 50% or 2.5 Gigapixels, I’m having trouble outputting a complete tileset at level 17 but it is still great to explore at level 16.

The images are from the State Library of Queensland’s out of copyright photographs from their photograph collection “People and places from across Queensland across time” . Data source is here: http://data.gov.au/dataset/picture-queensland/

The image for the mosaic is NASA’s Blue Marble Imagery cropped to the political boundary of Queensland. The mosaic was created using AndreaMosaic’s 64bit professional version, Photoshop CS5 and DeepZoom tools. It was processed on a Dell dual 6 core Xeon X5680 T5500 Workstation with 24GB Ram. It took just under 7 days to compile the images, mosaic, process, tile and upload to our website. The energy used to power the hardware was offset by our 6KW/h Solar System and the awesome Queensland Sun.

Since the requirements of the competition are to upload to flickr I’ve made a little 1024px representation of the artwork combining the zoomed out view of the mosaic with a magnifier. Each one of those pixels is a separate image.

Unable to debug JavaScript in VS2010?

I was scratching my head a bit last night when I needed to debug some JavaScript in my project. I’d one all the things I thought I needed to do:

  • Turn on ASP.Net debugging
  • In the Debugging Session turn on script debugging
  • In Internet Explorer I’d turned OFF disable JavaScript debugging in IE and other (just to be sure)

But my breakpoints still weren’t being hit! Turns out when you have Silverlight debugging on , it disables ASP.Net debugging even though you have it selected. So the fix….uncheck the Silverlight Debugging in the project properties and it starts working again.
