Problèmes projections openlayers/Mapserver
Bonjour,
Je suis étudiant et assez débutant dans le domaine du webmapping.
Dans le cadre d'un projet pour les études j'essaye de faire un guichet cartographique pour une commune.
Il s'agit d'afficher un fond de plan (choix orthophoto ou google maps) et par dessus d'afficher des données vectorielles type conduites, plan de zones...
Mon problème actuellement est l'affichage des orthophotos : j'utilise Mapserver voici le code du .map :
Code:
MAP

}
</script>Les orthophotos apparaissent en partie, et c'est lent.
Pour l'instant j'utilise seulement les orthos en fond :
Ii y a une interférence entre le système google maps puis celui de mes données.
Quel code utiliser pour améliorer cela?
Quel code pour afficher correctement les données vectorielles (wfs..) ?
Merci d'avance
