We beginnen met een vrij eenvoudige starter-app - slechts een basemap waarmee je kunt in- en uitzoomen. Niets bijzonders, behalve het feit dat we niet een van de standaard Esri-basemaps in web mercator gebruiken.<\/P>
In plaats daarvan gebruiken we
De projectie van deze kaart is
In de onderstaande code zie je dat we de webmap refereren via zijn id:
Om deze kaart aan de view toe te kunnen voegen, stellen we de spatialReference<\/SPAN> van de view in op 27700<\/SPAN>. En om de center<\/SPAN> van de view te bepalen maken we een nieuw punt in precies deze projectie:<\/P>center: new Point({x: 500000, y: 500000, spatialReference: 27700})<\/SPAN><\/P><\/P>Volg deze link om het eindresultaat van deze oefening te zien:<\/P>
En let op: we zijn net begonnen! Meer functionaliteit zal worden toegevoegd in latere oefeningen.<\/P>
Wordt vervolgd.<\/P>
