Bonjour à tous.
Je suis un newbie en Mapserver et j'espere que ma question est pertinente.
Mon fichier .map reference 3 layers Mapinfo (.tab)
Les 2 premiers layers sont visibles sans probleme. Le 3 eme lui ne l'est pas.
Voici le fichier Map

Le layer "ecoles" n'est pas visible.
Comme conseillé par ObiWan Kenobi "Use the source, Luke". Le probleme lors du dessin est que je me fais clipper par l'extent visiblement parce que un extent en kilometres est comparé avec des degrées(OGRLayer::FilterGeometry ligne 783 de ogrlayer.cpp)
voilà la callstack.

La difference principale est selon moi l'unité utilisée. Pour l'un en degrés pour l'autre en metres.
Mes questions:
- Mon analyse vous semble elle correcte ?
- Comment puis je modifier le fihcier ecoles.tab afin que l'unité utilisée soit degrés.
J'ai fais de nombreux essais dans Mapinfo sans y parvenir.
J'ai tenté de changer l'unité du fichier .map en dd et le probleme existe encore

Pouvez vous m'aider ?
Nicolas

ton analyse est bonne, il te faut reprojeter le layer qui ne s'affiche
pas dans la projection des deux autres :
ajoute un bloc PROJECTION au bloc MAP qui définira la projection de la carte
ajoute un bloc PROJECTION dans tous les blocs LAYER qui ne sont pas dans
la projection de la carte, en y spécifiant la projection de ce LAYER.
par exemple :
PROJECTION
"init=epsg:27572"
END
pour du Lambert II étendu

concernant les unités du bloc MAP, il faut indiquer celles de la
projection utilisée : DD si c du non-projeté (WGS, EPSG:4326) ou METERS
pour du lambert

Bonne chance !

GENIAL !!!! ça fonctionne maintenant.
Comme indiqué par Guillaume
dans la section MAP j'ai ajouté :
PROJECTION
"init=epsg:4203"
END
UNITS DD
dans la section Layer du layer qui ne s'affichait pas j'ai ajouté :
PROJECTION
"init=epsg:20356"
END

MERCI encore Guillaume. :-)
