bonjour à vous

je cherche désespérément à comprendre comment reverser une carto de MapGuide sous OpenLayer
je suis tombé sur plusieurs sujet qui parle de la manipulation à faire
comme http://dev.openlayers.org/releases/Open … de-js.html
ou encore http://zacster.blogspot.com/2008/04/map … d-map.html
et encore http://georezo.net/forum/viewtopic.php?pid=117113 (bonjour à Nath ;-) )
mais hélas ce n'est pas très claire pour moi

je vous laisse aussi un tutoriel (source OpenLayer )
ma question est d'avoir un petit retour d'expérience sur ce sujet et un peu plus d'éclaircissement

et un grand merci à vous
Jean-Marie

Bonjour,

Je lis ce message aujourd'hui (hello Jean-Marie !), j'avais mis de coté cette problématique depuis un moment, et j'y reviens maintenant. As-tu trouvé des réponses ?
Mon but était alors de remonter des couches mapguide dans l'api du géoportail. J'en suis à me poser la question, faut-il continuer dans cette voie, ou abandonner mapguide pour travailler directement avec l'api ?
Si quelqu'un a des réponses ou de l'expérience sur ces sujets, je suis preneuse.
Merci à tous

Nath

Bonjour Nath

Hélas je n'ai pas plus d'info que toi sur ce sujet et je n'ai pas avancer non plus
bonne journée

Gwenael Bachelot · Thu 16 April 2009 20:59

Bonsoir,
Il y a un exemple en ligne à l'URL suivante :
http://enterprise.mapguide.com/googleopenlayers

Le code source de la page est lisible directement.

Cordialement,

Bonjour,

J'aimerais pouvoir récupérer la carte courante et les calques affichés dans MapGuide (sans codage en dur!), mais comment faire concrètement? Ne pourrait-on pas utiliser l'id session?
En lisant les codes sources proposés par Jean-Marie au-dessus, il y a des choses intéressantes mais que je ne comprends pas...

/*
The MapGuide layer can also be created using mapname and session as follows provided there
is some wrapper code to obtain a valid session id and mapname
var params = {
mapname: 'Sheboygan47b3560bf1071',
session: '043bb716-0000-1000-8000-0017a4e6ff5d_en_7F0000010AFC0AFB0AFA'
};
=> ??? D'où sort ce numéro de session?

Merci d'avance pour votre aide!

Sébastien
