Nous commençons avec une application de démarrage assez simple - juste une carte de base vous permettant de zoomer et dézoomer. Rien de vraiment spécial, sauf le fait que nous n'utilisons pas l'une des cartes de base Esri par défaut en web mercator.<\/P>
Au lieu de cela, nous utilisons
La projection de cette carte est
Dans le code ci-dessous, vous pouvez voir que nous référons la carte web par son identifiant :
Pour pouvoir ajouter cette carte à la vue, nous définissons la spatialReference<\/SPAN> de la vue à 27700<\/SPAN>. Et pour center<\/SPAN> la vue, nous créons un nouveau point dans cette même projection :<\/P>center: new Point({x: 500000, y: 500000, spatialReference: 27700})<\/SPAN><\/P><\/P>Suivez ce lien pour voir le résultat final de cet exercice :<\/P>
Et veuillez noter : nous venons juste de commencer ! Plus de fonctionnalités seront ajoutées dans les exercices suivants.<\/P>
À suivre.<\/P>
