What red colour indicates here?

It is a false Colour Image Brother.

In a false-color image this close correspondence between subject color and image color is altered. That can happen in many ways. For example, a photographic negative could be called a false-color image, since it shows the complementary colors of its subject. However, the term "false-color" is typically used to describe images whose colors represent measured intensities outside the visible portion of the electromagnetic spectrum (or outside the electromagnetic spectrum altogether)

Here's a sat zoom. Know where on the image this area is?

What red colour indicates here?

It's all about false color imagery. For example, here's an area, a grassland/field with natural shrub cover , as it appears in natural color in this aerial oblique view:

vegetation covers.

A notably different color version (typical false color rendition)
in which various kinds of vegetation display in several tones of
red, pink, or yellow (the latter two may indicate a degree of
stressed or unhealthy vegetation).


This type of projected color combination, yielding the false color IR composite, is ordinarily used to emphasize a property of healthy vegetation in which incident light in the range of 0.7 - 1.1 µm reflects strongly from the internal cells of plants, giving rise to bright tones in the color IR film.

Cheers!
