You can't.
"World's Coastlines From Above" is not available on Amazon.com or eBay. It is not available from HDNet (now AXS TV - and not available there either). It does not appear available from any torrent site to any location outside of metropolitan Paris.
The French version, under the title "Côtes d’Europe vues du ciel", was available from Amazon until 2010, but it was playable only on European devices (Region B) and not devices available in the US (Region A). See Region codes at

It's in the catalog of the distributor, Terranoa (
http://www.terranoa.com/english/fiche-detail.php?id=1342), under the title "Europe's Coastlines From Above". Si tu converser en the langue Francais avec fluence, you might try calling Marie-Pierre Izard, +33 1 55 25 59 39. But they probably don't retail anything.
It's in the catalog of the production company, Gedeon Programmes (
http://www.gedeonprogrammes.com/en/fiche.php?annee=2006&id=171&type=1&real=&titre=&resume=&pos=7), also under the title "Europe's Coastlines From Above". Bon chance, mon ami.
If you look hard enough, the disappointment in your search will probably overwhelm all delight you might have had if you had actually managed to find it.
C'est dommage, n'est-ce pas?
