Distances between harbours

LIRA · Posted: Sat Jun 27, 2009 4:37 pm Post subject: Distances between harbours

Hello,

is it possible to publish a database (text-based) including the distances between the harbours in pocxxl ?

I need sth. like this for my admin-tool for pocxxl to calculate the real times needed for travelling from port A to port B.

By time I build a database on my own (act. including 2500 items), but the possible combinations maybe 10000 and more indiv. distances.
So, if a database is available, I can save a lot of time in future.

Mike

The distances are calculated in real time. You would need the algorithm of the game to create a database with all possibe routes - and then there would be no need for the database, because you could calculate the distance when you need it.

and they depend on the ship

Thanks.

That means:
the route, a ship takes from e.g. Rotterdam to Sydney depends on what type of ship this route takes ?

Let me say:
it is not possible to calculate e.g. tanker from Dubai to Capetown = 5090 nm.
Next time I use a smaller tanker or the same tanker with less fright on it, then the distance is not 5090 nm ? Alternate routes (storms etc.) I can decide I take. But standard-route is always calculated individually.

Correct ?

If so, how can "company-owner" calculate and decide, to accept an order, if there is no possibility to calculate, the estimated ships can arrive the dest-harbour in time ?

depends if they can pass the panama canal or the suez canal for example. Also depends if you use the extended maps.
The program uses one of the mps and tries to find a shortest path to the destination.

does this mean, that the three different maps are for the three types of vessels? Panmax, post panmax and suezmax?

@Christian
have a focus on both canals:
map3 = all canals are open
map4 = panama closed
map5 = panama and suez are closed

different routes for using suez/panama is ok.
but for ships who cannot use both of them the route should be always the same.
Is so ?

If yes, all ships, not using suez or panama, travelling from dubai to new york, sail the same distance (no storm astimated).. Correct ?

yes - there is no random choice.

ok, that's I want to know.
Thanks
