Projection UTM
bonjour,
j'ai des shapefile qui ont la projection UTM 28 nord , j"ai essayé de les mettre sur la ma carte main j'ai pas pu.
après une vérification j"ai constaté dans le MetaData il y a une difference en locale cordinates
pour le premeir j'ai In projected or local coordinates
Left: -12.000000
Right: -6.000000
Top: 27.300000
Bottom: 14.000000
pour le deuxième
In projected or local coordinates
Left: -12.000000
Right: -6.000000
Top: 27.300000
Bottom: 14.000000
comment je peux mettre le premier en mètre
merci

Re: Projection UTM
bonjour,
Logiquement, comme ta couche est projetée, tu peux avoir les distances selon l'unité que tu désires (et donc en mètre).
Ce que je ne comprend pas bien c'est pourquoi tu n'arrives pas à afficher tes couches (quel est le message d'erreur?).
Donne-nous de plus d'infos.
Cordialement

Il m'affiche pas un message d'errure.
mais je vois pas les deuxcouches sur la memeplace alors qu'ils doivent se superposer.

Re: Projection UTM
Il semble effectivement que la première couche n'est en fait pas projetée. Il faudrait donc le faire grâce à l'outil "projeter" de la toolbox.
Est-ce que cela corrige ton problème?

Re: Projection UTM
Bonjour,
j'ai changé la projection en utilisant ToolBox , mais c'est toujours la même chose.

Re: Projection UTM
Bonjour
mes recherches m'indiquent que ta zone d'etude se situe au senegal, pas vrai?
Il faut d'abord que tu lui definisses une projection sous arc catalog et ensuite tu le projectes
ça devrait marcher normalement.
merci
Mame
