Creating new web map, featuring other webmaps on portal

[VaL]

Hi all,

In our portal I have ~10 webmaps covering different projects. Each webmap has different number of layers (web feature layers).

The projects cover different areas (sometimes overlapping).

Is there a way to create a new webmap which will show all 10 webmaps' data in one place?

I know it will be very messy and potentially not very performing, but this is an ask.

Are you asking it have all of the layers from each map or just where all the data overlaps?

Hi @Laura 

I need it to have all layers from all webmaps - regardless of duplication - in the new combined webmap.

[Laura]

You can just go in and add all of those layers to a new map then. Is the problem you don't know what layers you need?

Hi,

Problem is really that some of the web maps have 10s of layers (wfs). 

So not very easy to start adding layers to a new web map. 

Unless if there is a python way to interrogate every web map2 in turn, get all layers' ids/names and then create a new web map and iterate through the layers list and add each of them. 

Is this possible?

[Laura]

I mean that is not unheard of. I have maps with loads of utility layers. I just manually add it all in because I know what I need and many are part of group layers. I am not good with python so you'll have to see if someone else can answer that.

In my case I have 10 projects with 100s of layers (some are group layers) so manual adding is not really an option.

Hello @VaL,

I may be able to provide some guidance on your question. Can you clarify if you are looking for a workflow, such as a Python script, that will assist you in combining a large number of layers from multiple web maps into one or are you looking for a way display and present multiple maps?

Looking forward to seeing how I can assist further.
