However, i'm not exactly sure how to read the DSS post-scanned map ui ( filtering thru each Bio type as you said ) of the globe surface itself , to know exactly where to LAND in order to maximize the spot area whereby the Bio 'plant' ( or resource or bacteria or whatever ) is actually located. Is it just a matter of land random area and then use SRV to search & explore?

Although the various shades of blue might look like a "heat map", in fact it is not. The shade variation is just caused by the underlying topography. So, in essence the map shows where the bio/geo in question can be found (the blue) and where it can't (the rest).
The way to actually find the bio/geo is to fly down to the surface and then fly along about (or under) 100m and just rely on the Mk I eyeball to spot what you are after. You soon learn where to look for certain things and what they look like - some things are easy to spot, some things can be infuriating. I tend to use the ship to fly from sample to sample, others prefer to use the SRV to travel on the surface, you will find your preference as you go on.
