Aan de slag met ArcGIS JavaScript - Nederlandse basiskaartgalerij

Egge-Jan_Pollé

BasemapGallery

Tot nu toe heeft onze applicatie (zie deze oefening) slechts één basiskaart. Hier willen wij de mogelijkheid toevoegen om van basiskaart te wisselen, en zo bijvoorbeeld ook een luchtfoto als ondergrond te gebruiken.

Het toevoegen van een basiskaartgalerij gaan we doen met een BasemapGallery widget. Als je deze widget zonder verdere argumenten in een web app toevoegt, dan bevat deze vanzelf al een aantal basiskaarten. Maar helaas, helaas, al deze standaardbasiskaarten zijn in de Web Mercator projectie (Spatial Reference: 102100 (3857)), en dat werkt niet voor onze kaart, want die is in de Nederlandse projectie (Spatial Reference: 28992). Alle kaarten in de galerij moeten in dezelfde projectie zijn.

Om onze basiskaartgalerij te vullen met kaarten in de juiste projectie, moeten we eerst een aantal kaarten als Basemap definiëren, en deze vervolgens aan een lokale bron, een LocalBasemapsSource, toevoegen.

Dit zijn de 6 basiskaarten van Esri Nederland die we in deze oefening in onze basiskaartgalerij gaan stoppen - maar je kunt deze lijst natuurlijk zelf aanpassen met andere basiskaarten. In het script worden de kaarten aangeroepen via hun unieke id:

Topo RD
Open Topo - die mooie, van Jan-Willem van Aalst
Stratenkaart RD
Luchtfoto (RD)
Lichtgrijze Canvas RD
Donkergrijze Canvas RD

De broncode staat hieronder. Klik hier om de applicatie in actie te zien.

Oh ja, onze basiskaartgalerij neemt nu wel veel ruimte in beslag op het scherm. In een volgende oefening zullen we zien hoe we een widget dicht kunnen klappen en onder een knop kunnen verbergen.

Hoi Egge-Jan,

Ik probeer dit allemaal wat beter te begrijpen, maar ik heb er toch wat moeilijkheden mee.

Hoe krijg ik net als jij dat enkel België zichtbaar is en niet de rest? Je begint met een basemap waarbij de verwijst naar een PoralId (Topo RD), maar waar haal je die info vandaan? Als ik dan in de docs wat lees vind ik dit: PortalItem | ArcGIS API for JavaScript 4.12 maar waar/wat is die portal?

Enige hulp met dit alles is welkom om me op het juiste pad te zetten. Eventueel via mail mocht je willen (sergedb(at)gmail).
