Bienvenue sur PostGIS.fr

Bienvenue sur PostGIS.fr , le site de la communauté des utilisateurs francophones de PostGIS.

PostGIS ajoute le support d'objets géographique à la base de données PostgreSQL. En effet, PostGIS "spatialise" le serverur PostgreSQL, ce qui permet de l'utiliser comme une base de données SIG.

Maintenu à jour, en fonction de nos disponibilités et des diverses sorties des outils que nous testons, nous vous proposons l'ensemble de nos travaux publiés en langue française.

24
25    A specific ``Ext.form.FormPanel`` whose internal form is a
26    :class:`GeoExt.form.BasicForm` instead of ``Ext.form.BasicForm``.
27    One would use this form to do search requests through
28    an ``OpenLayers.Protocol`` object (``OpenLayers.Protocol.WFS``
29    for example).
30
31    Look at :class:`GeoExt.form.SearchAction` to understand how
32    form fields must be named for appropriate filters to be
33    passed to the protocol.
