方法
場合によっては、複数の Web マップにプログラミングできるため、スクリプトを使用して Web マップを作成することをお勧めします。 JSON ファイルで指定した定義を使用し、ArcGIS API for Python の gis.content.add 関数を使用して Web マップを作成できます。
GIS モジュールの gis.content.add 関数を使用し、JSON ファイル表現から Web マップを作成できます。 これには、次の 2 つの方法があります。
注意: JSON 記述を定義するほうが、作業時間は長くなります。 ただし、この方法であれば、ユーザーはスクリプトの JSON 表現を変更することができます。
以下の手順は、json モジュールを使用して JSON ファイルを読み取り、Web マップを作成する方法を説明しています。
必要なモジュールをインポートします。
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)
