Extracting ArcGIS REST Server from Webmap URL

Question

I would like to view certain Webmap information in my desktop GIS software, and I'm looking for a way to extract a REST server (or, in future situations, WMS/WFS/WCS URLs) from a webmap website.

I reviewed these two posts:

• Find out ESRI REST URL for web map which is hiding it
• Adding ArcGIS webappviewer to QGIS?

It's clear that you need to inspect the website/use developer tools to find the feature service URL from the Network Tab... and this is where I run into problems. For example, I'm trying to get the REST URL for this website https://tpwd.maps.arcgis.com/apps/webappviewer/index.html?id=f5e8debeaa994abe888d86a7112649ff. But when I analyze the network tab, I can't find the REST server URL.

How do I find this URL using inspect element?

• sutan: search 'query?' on the network tab on your inspect element. check this out, it works

Answer 1

The first thing to do is get the application's configuration. Do this by searching the Network tab in the browser's Developer Tools.

If you filter on f5e for instance (which is part of the ID in your URL), you will find a request to the Web Mapping Application: https://tpwd.maps.arcgis.com/sharing/rest/content/items/f5e8debeaa994abe888d86a7112649ff/data?f=json

The response is a JSON file which has a map attribute that in turn has an ItemID of ef0d5fe1a5f841ffb432445b1913cb55:

Web Mapping Application JSON

Now, search the Network tab for that ID. You will find two items, you need this one: https://tpwd.maps.arcgis.com/sharing/rest/content/items/ef0d5fe1a5f841ffb432445b1913cb55/data?f=json

This is also a JSON file, of the Web Map this time, containing all used layers and basemaps.

• greyhug: Thank you, that was helpful, however I haven't been able to add the map to my QGIS. I find the area that you're talking about, and I successfully reach a REST server page when I search for the URL from layer 0 "GCWA_2016HabClass_3319". However, when the layer does not display after it's added to my map. Is this ia security/access view, or is there another step I have to complete in order to see map?
• Berend: Sorry, I don't know about qgis. You might ask a separate question about that .
• greyhug: Okay no worries, and thank you for your help. I realize that that was not specified in the original question, so a new post would be best.
