Guess the Map VIII: Didn't Color the Island Countries

[shadowplay]

Rivers patroled by the coast guard or some sort of border services agency?

 

[Takhisis]

Number of major/main river basins?

 

[Fuzzz]

Boat lifts, or maybe locks longer than x meter?

 

[Takhisis]

Argentina has no boat lifts that I know of.

 

[TheMulattoMaker]

Something to do with waterfalls, perhapsibly?

Vaguely related to natural resources.

...it does relate to rivers.

Or maybe something to do with the number of rivers where gold has been found (panning, etc.)?

 

[Thedrin]

The natural resource it's related to is rivers.

 

[TheMulattoMaker]

Places where you can ride a riverboat (tourism)?

 

[W|M]

Amount of freshwater fishing compared to saltwater fishing?

 

[TheMulattoMaker]

...I'm 'bout stumped. It doesn't seem like "number of major rivers", because I'm pretty sure Russia and China would be #1 and #2. The grayness of Egypt and Sudan rule out "river length". The fact that Brazil isn't #1 means it's probably not "drainage basin area" or "overall flow". And since it's not related to energy, it's not hydroelectric anything.

All islands are coloured correctly.

Map:

Spoiler :

Black (15) > Dark Grey (12) > Maroon (9) > Red (7) > Orange (6) > Yellow (5) > Green (4) > Blue (3) > Indigo (2) > Purple (1) > Light Grey (0)

Portugal is coloured incorrectly. It should be the same colour as Spain.

Amount of osmose plants?

 

[Thedrin]

Amount of osmose plants?

Thanks, I was previously unaware of this. Is 0.75kWh/m^3 good?

 

[Takhisis]

As in desalination facilities, you mean?

@Thedrin: it'd be a great visual scale to have a scale of shades of the same colour.

Edit: x-post.

We need another hint.

I'm not sure how to do that with Paint. I'll keep it mind for the next time I make a map. I quite liked the previous maps that I did, garish though they may have been, but I do agree that this map looks really ugly.

We need another hint.

I wrote this 10 minutes earlier.

All islands are coloured correctly.

Also, I'll reiterate that Portugal is coloured incorrectly. It should be the same colour as Spain.

 

[say1988]

Based on Hispaniola, Borneo, and New Guinea being the islands coloured, Number of rivers crossing national borders? It also mase sense why Spain and Portugal would be the same, if no river crosses the pyranees.

 

[Thedrin]

Getting closer ...

 

[say1988]

Bridge border crossings?

 

[classical_hero]

The number of rivers that form part of the borders?

 

[Thedrin]

Correct.
