Satellite Imaging
« on: June 23, 2014, 02:41:30 AM »
Hi All,

I am an Australian racing at Lake Gairdner on a Vespa :) and I am doing some investigation into using satellite imaging to help with timing of races (i.e. best dates to run) and choosing the best track layout.

What I have been doing is getting the new thermal imaging satellite data from Landsat 8 and then filtering it so it highlights differences in ground temperature. This seems to show quite accurately where good and bad salt is. If looking at the lake over time is also seems to show where wet patches have dried in layers.

It would be good to team up with someone at Bonneville to see if we can do a back scratching exercise. I can generate the data for this years Bonneville (i.e. a series of processed satellite images) and it would be good to get some feedback on if it helps and how best to use them.

Here's one I whipped up today which is a recent Bonneville thermal image. I am gathering those are tracks I can see?



Is there interest in this? Does the above image look like it is telling you something you already new?

you're an absolute gem Paul.

Can't wait to see the results of this.

Is the darker area thicker or thinner?

Very interesting, thank you.  I changed the contrast some and put in my best guesses for what is going on.  When was the image taken? They do have the new courses laid our and I thing graded.  If the image isn't very recent then I'd say that is last year's tracks.

Paul has explained a lot in this link, although mostly lake G, it's basically the way he reads the info, Bonneville track conditions is his latest project

The picture is from June 19 2014, it is showing surface temp. Darker is cooler and due to more moisture. At Lake Gardner we could pic out all the tracks and pit area.

The full res 4M image is here: http://files.internetscooter.com/dlra/2014/lake_condition/cropped_LC80390322014170LGN00_B8.tif

And here is how I processed it: http://www.vespalabs.org/Projects/Lake_Gairdner_Satellite_Imaging

Happy to provide more info and help :)

Via general scaling, it would appear that there is moisture around the 2mi. marker if that course towards the top is the long course being used this year?
