    postgis keyline S'est terminé left

    Développer des fonctions de postgis pour un WebSIG qui puisse faciliter la conception par keyline des champs d'une ferme agricole. La conception de la keyline a été conçue dans les années 1930-1940 par Yeomans, un géologue minier australien, qui l'a appliquée à son domaine en Australie. Il est maintenant utilisé partout dans le monde. L'agencement de la keyline vise à faire bouger l'eau lentement, à l'étaler sur toute la pente, à l'approfondir dans le sol et à la stocker (les 4 S en anglais: slow, spread, sink and store). Tout cela dans la praticité: après avoir défini le design avec une ou plusieurs keylines, c'est-à-dire d...
