I used to coach Science Olympiad in Indiana. Currently I am working on my PhD in remote sensing at University of Nebraska-Lincoln. I saw several comments about recommended reading. I highly recommend both of John Jensen's books on remote sensing (Remote Sensing of the Environment and Advanced Digital Image Processing) though the first is probably the most useful.

I know this event can be difficult to study for since there are not very many practice tests out there. In my opinion you should know the different types of platforms (i.e. radar, lidar etc). I wrote one of the regional test for Nebraska and I posted it on my university's ftp server which can be reached at:

ftp://snrftp.unl.edu/Outgoing/Science%20Olympiad/

I do not make any promises on how long it will stay up. Good luck!
Thanx...
A couple things?
Can we use it on our test exchange? (If not, at least add the link?)
Could you please repost it in Word 97-03 Compatibility Mode?

I don't care if you put it on the test exchange. I added MS Word 97-03 files and PDF versions to the ftp link.

Whoaaaaaaa...

Regionals is tomorrow, and now I'm worried...
I was expecting an easy gold (I got one at a invitational ten times harder than our regionals) but now I'm not half as sure... :shock:
That's one hard test...

Well, I added it to the test exchange!
Thanx for the test...and the wake-up call!

Dude, I took that test! It was really interesting, plus my partner and I got first! And hooray for someone else from Nebraska posting something :D

Hey Guys,
I had a question on my regional test that I haven't figured out how to answer. Does anyone know how to solve this one?

Assume that the spatial resolution of the satellite imaging system that took these images was 79 meters. What does that mean in terms of the pixel size in Image 1? Be specific with respect to image distance on paper.




If there's anymore information that you need, I'll be sure to post it!


Thanks!

The more I think about it, the more I realize that I know absolutely nothing about this event. Looks like I got my partner to thank for the medals I got here.
2009 events:
Fossils: 1st @ reg. 3rd @ states (stupid dinosaurs...) 5th @ nats.
Dynamic: 1st @ reg. 19thish @ states, 18th @ nats
Herpetology (NOT the study of herpes): NA
Enviro Chem: 39th @ states =(
Cell Bio: 9th @ reg. 18th @ nats
Remote: 6th @ states 3rd @ Nats

I think that means 1 pixel = 79m

Smallest thing that it can detect is 79 meters in size. I'm not sure what it has to do with pixel size though. Was there any other given information? As in the ppi or something?

Yeah, but I'm assuming smallest thing is 1 pixel? I don't think the sensor can produce anything smaller, and that's the definition/limitation of the pixel.

Edit: Winneratlife is right. Spatial resolution of 79 meters means that each pixel is 79metersx79meters.

If you have a scaled image, you have to square the scale to find area, correct?

:P

If you mean to find the area of one square inch, and the scale is 1 in = 100 miles, then yes, because its 1 in by 1 in = 100 miles by 100 miles = 100^2 square miles.



Does somebody have a good idea of what to study for the bio portion? (I'm epic at sensors, but epic fail at bio) And where to study it?
