We were tasked to find and article and I found this one that shows a map of “Before” and “After” of the flow of the rivers. The purpose of the map included in the article is to show where the flood waters had risen as compared to the pre-flood state in Rockhampton, Queensland.
Floods in Rockhampton - before and after
By BBC News Mobile January 7, 2011
“The image above right shows the devastating impact of flood waters on the town of Rockhampton, Queensland, Australia. It was taken on 5 January, when the Fitzroy River was at its peak level of 9.2m.
The image was created using radar data collected by the Cosmo-SkyMed satellite constellation, operated by the Italian Space Agency. The satellites are capable of taking images day and night, as well as through clouds. The flood maps are made available to assist emergency services in their work.
The flood data was overlayed on an existing optical satellite image of the Rockhampton area by BBC News.

Also I found two videos about the disaster that I wanted to share.
The first is great video of a fly-through of a model that was designed by AAM Group before the flooding occurred. You can really see how the city of Brisbane appears spatially with varying levels of water. I would be interested to know the tools that they used to generate this 3D spatial view of the city.
The second video really puts a face on the disaster one year later. Not much spatial information on this one, but worth a watch nonetheless.

The fly-through video is fantastic! I don't know which software they used to model the flood and produce the video but I know a software called Blaze View that has similar functions. I used it a couple of times and is excellent for interactive fly-through.
ReplyDeleteThe video is very good at portraying the extent of the flood and the apparent density of people there.
ReplyDeleteI really like the video you included, and the maps really show the extent of that rivers' flooding. Very nice post.
