Remote Sensing C

What is the difference between false color imaging and pseudo color imaging? I'm not understanding the difference very well upon searching google.

What is the difference between false color imaging and pseudo color imaging? I'm not understanding the difference very well upon searching google.

False color is you assign different bands of light to R, G, and B in an image, it's just it's not red assigned to R, green assigned to G, and blue assigned to B. One of the most common types assigns NIR, R, G to R, G, B; but you could also do it with other types of light showing up as whatever color on the image.

Pseudo color, each color represents a different value within a certain variable - so, sea surface temperature, where you have a scale from, like, blue to red, for cool to warm, this is pseudo color. Rather than it being colors assigned to red, green and blue and the colors that are assigned are not the real ones, it's basically like an image going from black to white for low values to high values, except they use color to make it easier to tell.

I have been asked several times, including on my Regional test, how many pixels are in this image. I don't have examples of this because it was on a Regional test, but can someone explain how you are supposed to be able to tell? (All the answer choices were low numbers, but I thought there were a lot of pixels in images)

Count the "squares" in the image. Some example images may just be a grid of a few squares where each square represents one pixel

Sign-up to compete in a nation-wide remote sensing competition! This competition IS NOT AFFILIATED WITH NATIONAL SCIENCE OLYMPIAD. The test materials will be sent to registered competitors by email, but all materials will publicly released eventually. Raw scores and rankings will be released.
The goal of this exam is for students across the nation to be able to compare their mastery of remote sensing with peers.

I will edit this post with a list of schools that are currently signed up. If you have any questions, feel free to PM me!

I am not ready to stop caring about this event, so thank you for this...

You're very welcome! Unfortunately the test won't be national difficulty because the actual purpose of this test is the Florida State Tournament, but at least you'll get a chance to compete against others at that level in a way

Testing materials have been emailed out! Results will be posted on SciOly Discussion facebook group as well as emailed out by Sunday, April 1st at 11:59pm

Is it just me or is whythelongface's test on the test exchange super hard?

It's just long, and the answer key had a few errors that I only spotted after submission, but I wanted to include as many topics as I could, since it's just a practice test. I guess I didn't emphasize climate as much as I would've liked, but I didn't know the current topic at the time anyway so...
