Hi Daniel,

I just had contact with him yesterday after I noticed the incorrect 
rendering. He responded quickly. I asked him whether he was aware of the 
problems, and if he could use some help. He has seen the flooding and 
reverted some of the changes yesterday, notably the broken coastline 
northeast of Ile d'Orleans. He wanted to tag the coastline of the. St. 
Lawrence as a riverbank, so it would show up properly (as a blue area). 
This is a known issue with mkgmap. He will leave the riverbank tag 
upstream of Ile d'Orleans, but has reverted the other errors. Most 
notably the multipolygon for the St. Lawrence he made has been removed 
again. In this multipolygon Ile d'Orleans was tagged as natural=land, 
which caused it to be rendered white (because "natural=land" is one of 
the topmost styles). I've quickly checked his changes, and the coastline 
seems to appear all right. I still need to do a bigger check.

So, currently the St. Lawrence is tagged both as natural=coastline and 
waterway=riverbank between Quebec City and (at least) the St. PIerre 
lake. Would that be a problem? For the rendering it should work nice, 
but having duplicate / complimentary tagging should be avoided. I'd like 
to propose to use the natural=coastline from downstream Quebec, and use 
waterway=riverbank upstream. Right now Alain has drawn this boundary 
just east of Quebec City. I'd rather move it towards approximately the 
ferry connection with Levis, since upstream the flood/ebb cycle is much 
less strong.

Here is Alain's full answer:

J'ai vu ce matin après quelques jours n'inactivité, que la rive nord du fleuve, de la pointe de l'île d'Orléans à la ville de Baie-St-Paul ne se dessinait pas correctement sur OpenStreetMap.

Je crois maintenant avoir enlever toutes les modifications à l'est de la ville de Québec, y compris l'île d'Orléans et les deux rives du fleuve.

Cependant cela ne corrige pas l'erreur. Peut-être, comme tu l'indiques dans le deuxième courriel, est-ce à cause de la mise-à-jour qui ne se fait qu'à tout les mercredi.

Mon but était de tagger waterway=riverbank jusqu'à l'est de l'île d'Orléans, endroit ou la marée est supposée se manifestée (?). Le reste de l'estuaire du fleuve peut demeurer avec natural=coastline c'est vrai qu'il est très large. Cependant, à ma connaissance, lorsque les rives du fleuve sont marquées comme natural=coastline, le fleuve se dessine comme natural=land sur les gps-garmin lorsque passé à travers le logiciel 'mkgmap'.

J'ai essayé de modifié les fichiers de Style, les fichiers '.TYP', mais sans résulats. Mais en marquant les rives du fleuve avec waterway=riverbank, et en inscrivant les rives dans un multi-polygone, comme indiqué dans la documentation, ils ressortent correctement sur les Gps Garmin et le logiciel QLandKarteGt.

Je pensais bien avoir pratiquement terminé mes modifications, mais cette erreur me complique la vie. Je ne parviens pas à la cerner.

Ton aide serait la bienvenue !

Regards,

Frank
