HOW TO
In einigen Fällen ist vorteilhaft, eine Webkarte mit einem Skript zu erstellen, da dieses für mehrere Webkarten programmiert werden kann. Mit der in einer JSON-Datei angegebenen Definition kann die Funktion "gis.content.add" in ArcGIS API for Python zur Erstellung der Webkarte verwendet werden.
Webkarten können von einer JSON-Dateirepräsentation mit der Funktion "gis.content.add" im GIS-Modul erstellt werden. Dazu gibt es zwei Möglichkeiten:
Hinweis: Das Definieren der JSON-Beschreibung nimmt mehr Zeit in Anspruch. Der Benutzer hat dabei jedoch die Möglichkeit, die JSON-Repräsentation des Skripts zu ändern.
Die nachfolgenden Schritte beschreiben, wie Sie eine Webkarte von einer JSON-Datei erstellen, indem Sie sie mit dem JSON-Modul einlesen.
Importieren Sie die erforderlichen Module.
from arcgis.gis import GIS from arcgis.mapping import WebMap import json
gis = GIS("https://machine.domain.com/portal","adminuser","adminpassword")
print ("Successfully Logged Into GIS: ", gis)
with open('/home/jupyter/test2.json') as json_data:
data = json.load(json_data)
item_properties_dict = {"type": "Web Map","title": "Test Map","tags": ["test","test1","test2"],"snippet":"This is a snippet", "text":data}
newmap = gis.content.add(item_properties = item_properties_dict)
