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?

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?

Check out section 5.3 on this PDF from the Canada Center for Remote Sensing:
http://www.ccrs.nrcan.gc.ca/resource/tu ... tals_e.pdf
It's got some good stuff on forests in general, plus some great things relating it back to remote sensing.

Somebody telling me to read the exact tutorial I've been telling everybody else to read? (I've read it)

To both of you, I'd suggest reading the ccrs tutorial here:
http://www.ccrs.nrcan.gc.ca/resource/tu ... tals_e.pdf

It helped me a ton. It's a lot about the concepts of remote sensing.

Start with the ccrs tutorial. Move on to NASA with time, or learn about the individual satellites and their systems. Throw in some of the bio. That should just about cut it, I think. Also, you can check the glossary on the Remote Sensing Wiki, I based in on the content of ccrs.
:lol:

Okay, well, anybody have any other bio resources?

:lol: lol, guess I wasn't paying attention. Well, you're right, it's a totally great tutorial!
Another thing I did was search Wikipedia for articles about all the different types of forests. (boreal, tropical, deciduous, etc) There's some good stuff about them there.

for anyone else who took the New York state test this year, what were your opinions on it?
I still dont really understand why it was called remote sensing when there were barely any questions related to satellites and waves on it.

Oh joy...my partner bailed... (he has Fed this weekend)

So now I'm stuck learning the bio ALONE!

Help please? Like... a lot of it?
