407 Islands on the World Map
Can you identify all the coloured islands in this World Map? The list consists of islands that fit at least one of the following:
A. A >= 5k or largest lake island in the world
B. A >= 0.5k and #C <= 5 or A >= 0.4k and #C <= 3, not fluvial/lake
C. A >= 250 and #C = 1, not fluvial/lake
D. Part of country name or A >= 10 and #C = 1, not fluvial/lake/coastal
E. Contains capital/largest city/largest island of an otherwise missing island country
F. Pop >= 400k, not fluvial/lake/coastal (coastal included only if A>= 150 or A >= 75 and pop >= 1M; fluvial/lake included if pop >= 2M)
G. Maximum altitude >= 2,000 m, not fluvial/lake
H. Isolated islands (see notes)
I. Islands with at least 10 terrestrial endemic species
Islands are coloured with the same background with which the first criterion they meet is written.
Islands up to 200 square km have a ring around them that disappears when you guess them. Some category F coastal islands larger than 200 square km but smaller than 800 square km have a smaller ring.
Notes:
-a is the area in square km (k = 1,000); #C is the rank in area within a country
- under C you are shown the flags of the countries the island belongs to
- the list of countries is taken for the list of 2-letter codes
- an island is considered 'coastal' if it's within 5-10 km of mainland
- in sections B, C and D an extra island with A >= 100 can be assigned to a country by not counting shared islands and islands that have the same name as the country
- area is in bold if the island is the largest of its country
- an island is considered isolated if:
1) it's isolated by at least 800 km
2) it has isolation index >= 61 and A >= k
3) it has isolation index >= 61 and out of the following 4:
a) A >= 0.4k
b) island distance >= 400 km
c) group distance >= 850 km
d) continent distance >= 1.800 km
a) and another are true; b) and another are true; c) and d) are true and A >= 15 and island distance >= 200 km
Note that in a few occasions a group of small islands is considered as one in the data, in such cases the largest island has been added
A. A >= 5k or largest lake island in the world

Don't forget that the projection used distorts areas!

for real this is huge
Clause 3 under isolation notes says '3) it has isolation index >= 61 and out of the following 4:
a) A >= 0.4k
b) island distance >= 400 km
c) group distance >= 850 km
d) continent distance >= 1.800 km'
I believe the underlined section should be 'one of the following 4'.
