Re: Remote Sensing C

I'm leaning towards c, since water changes temperature more slowly than land. So during the day land will have a higher temperature than water, but at night the water will have a higher temperature than the land.

For your second question, I'm thinking red implies heat or warmth, since that's the general implication, but it depends on what purpose the image is serving. It can represent a lot of things, all anyone has to do is set a false color scheme and bam, you've got red.

Thanks, so to clarify colors themselves do not mean much, it depends a lot more on brightness?

If you're trying to identify what certain colors represent in an image (this is in regards to your second question) you first have to identify if the image is true-color or false-color. (This is usually fairly simple: Does the image look real?). If it's true color then it should be easy. If it's false color it's usually a bit trickier, but it's also simple once you understand the process used to make false-color images.

In a nutshell, the sensor collects energy at different wavelengths on the spectrum. Since some wavelengths (mostly IR) can't be seen by humans in true color, they can be assigned a color to appear in the picture (hence the term false-color, since it's not the actual color). There are a lot of reasons you might do this, but one of the more common ones is making infrared appear red. In this case, it's similar to what EAST said- this will often represent vegetation and brighter shades of red represent healthier plants.

You should also use context when interpreting images- take into account all information you've been given for the image. For a bit more on how to interpret images, look no further than here

Are there any measuring tools that would be helpful to bring into competition that aren't mentioned in the rules? I think the triangle, ruler and protractor pretty much covers it all, but if anyone has any other items they would recommend, that would be helpful.

The only measuring device I've ever had to use is a ruler. I believe you're also allowed a magnifying glass, which would probably be to your advantage to bring. You never know when you'll need it or anything else mentioned in the rules.

Well, since you're allowed to bring in any measuring device, I would recommend bringing in a camera to photograph various objects in the room, such as other teams' tests. If the event supervisor seems uncertain regarding the legality of its usage, just tell him that you are simply applying remote sensing in the field. Better yet, bring in a cell phone and conduct measurements of local UHF emissions. Really, though, I just bring in a triangle/ruler, a protractor, and an electron microscope. No need to get fancy.

Okay everyone I am completely new to this event! What should I particularly look over and study for this event? The events I've done in the past had powerpoints I could take notes off of, on the soinc website, but this one has no powerpoint...Also, do u have any strategies for making the 5 cheat sheets? The events I've done have only allowed one cheat sheet, double-sided so I am new to this! Thanks for all of your help! :)

Do some of the tests from the Test Exchange. They should give you a good idea of how the event is generally run.

Im new to this event- like i got assigned it 2 weeks ago- does anybody know where i can find what the false colors mean on the satellite images. also what are the best things to take notes on for this even.
