How to modify Text in Sketch Layer

KazFukuoka

There is a Web Map that has a Sketch Layer with a Text in it.
How can I modify the Text by using ArcGIS API for Python?

Hi @KazFukuoka,

Here's how you can do it...

from arcgis.gis import GIS

## access ArcGIS Online
agol = GIS("home")

## the name of the Sketch layer in the layer list
sketch_lyr_name = "Sketch"

## get the WebMap as an item object
item = agol.content.get("WM_ITEM_ID")

## get the WebMap JSON definition as a dictionary
item_data = item.get_data()

## for each layer in the operationalLayers
for lyr in item_data["operationalLayers"]:
    ## when we hit the Sketch layer of interest
    if lyr["title"] == sketch_lyr_name:
        ## iterate over the layers in the Sketch layer eg. Polygons, Polylines, Points, Text
        for sketch_lyr in lyr["featureCollection"]["layers"]:
            ## we are interested in the Text layer of the Sketch
            if sketch_lyr["layerDefinition"]["name"] == "Text":
                ## for each feature in the Text layer of the skatch
                ## at this point if there is only one text you could use
                ## indexing instead sketch_lyr["featureSet"]["features"][0]
                for f in sketch_lyr["featureSet"]["features"]:
                    #print(f["symbol"]["text"])
                    ## if the current text begins with what we are looking for
                    if f["symbol"]["text"].startswith("UNIQUE START OF TEXT"): # UPDATE CODE HERE
                        ## update the text
                        f["symbol"]["text"] = "UPDATED TEXT" # UPDATE CODE HERE

## update the WebMap Item definition
updated_properties = {"text" : item_data}
item.update(item_properties=updated_properties)

 

Update the text in lines 29 and 31.

Please let us know if this works for you.

All the best,
