Does VMAP0 data has different data for salt water and freshwater?
I'll investigate if the VMAP0 contains this information in principle,
but I doubt. Currently we only distinguish between the following:
crimson: 10:20:10 ~/TGPostGIS grep hydro FGScenery.conf | awk -F \| '{print
$2}'
rivers_stream
rivers_intermittentstream
canals_stream
lakes_lake
lakes_intermittentlake
floodland_floodland
You _might_ use that to determine if the water contains salt or not.
Cheers,
Martin.

If yes, then:
// Beginning Pseudocode
if (water==freshwater)
{
if (temperature 0 )
..Kelvin? ;o)
{
usetexture(freshwater_freezed);
}
else
{
usetexture(freshwater_unfreezed);
}
}
else
{
usetexture(saltwater);
..freezes too, the salt just drops the freezing a coupla degree (or
Kelvin ;o) ), depending on salinity. Most lakes above sea level stay
fresh because the salt is run off to sea or a lower lake, like the Dead
Sea in between Palestine and Jordan. The higher-than-sea-level
salty lakes are usually quite far from the seas.
}
This is not a perfect solution, but better than nothing in most cases.
