QGIS – Loading Windmill Layer from Vindbrukskollen’s Map

arcgis-rest-apiarcgis-serverlayersqgisweb service

My aim is to visualize the windmill locations at QGIS from Vindbrukskollen's map. To achieve this, right click on the map, select Inspect. I find this link (highlighted in blue, cursor over it):

Copying it here:

https://ext-geodata-applikationer.lansstyrelsen.se/arcgis/rest/services/VBK/lst_vbk_read/MapServer/export?dynamicLayers=%5B%5D&dpi=96&transparent=true&format=png32&bbox=266751.24243930646%2C6410467.740252377%2C551121.8258585681%2C6538509.733104119&bboxSR=3006&imageSR=3006&size=1890%2C851&layers=show%3A-1%2C-1%2C-1&f=image

From the …arcgis/rest… part, I think I should add this layer to QGIS as an ArcGIS REST Server.

In QGIS, I do Layer -> Add Layer -> Add ArcGIS REST Server Layer -> New and paste the above link into the URL field, with a name Sweden1:

Click OK, then Connect, and I get:

Connection failed: Parsing error

The little windmill symbol did make it into QGIS, just left to Sweden1 text, indicating that I am probably on the right track.

How to solve this parsing error to add Vindbrukskollen's windmill layer to QGIS?

You can access the individual layers if you shorten the URL to:

QGIS – How to Import Public Online Map Layer into QGIS

This works in 3.0, at least - add it using Data Source Manager as an 'ArcGIS Map Server' (not WMS) using the following URL

https://netmap.vodafone.de/arcgis/rest/services/CoKart/netzabdeckung_mobilfunk/MapServer/

You should now be able to see a list of layers when you clickConnect. Select your layer from the list, click on Add and that should load it into QGIS.

(You might want to add a basemap layer e.g. OSM to better let you navigate to the area you want)

Access ArcGIS REST Layers in QGIS – Using Python Console

Here is a script that will walk through the directory of folders, services, and layers. Ultimately, it prints the folder name, the service name, the layer name, and layer type for all available layers.

See this answer for clarification on how the URLs were derived.

import urllib.request, json 

root_url = r'https://ext-geodata-nationella.lansstyrelsen.se/arcgis/rest/services/?f=pjson'

# download the root json
with urllib.request.urlopen(root_url) as url:
    data = json.loads(url.read().decode())


# iterate through the 'folders' key of the root json
for folder in data['folders']:
    
    # construct a url to get the json of the folder
    folder_url = root_url.split('?')[0] + folder + '?f=pjson'
    
    # download the folder json
    with urllib.request.urlopen(folder_url) as url:
        sub_data = json.loads(url.read().decode())
    
    # some urls require a log in, in which case the json has a key called 'error'
    if 'error' not in sub_data.keys():
        for service in sub_data['services']:
            
            # construct the url for the service json
            service_url = folder_url.split(folder)[0] + service['name'] + '/MapServer/?f=pjson'

            # download service json
            with urllib.request.urlopen(service_url) as url:
                sub_sub_data = json.loads(url.read().decode())
                
            # iterate through service json 'layers' key
            for layer in sub_sub_data['layers']:
                
                # do something with results
                print(folder, '|', service['name'], '|', layer['name'], '|', layer['type'])
