@Koichi_Tsuji can you please share how to save in which column type the KML ?
You can find more details on KML layers in this article Map view type just scroll down to the section named “Use KML layers to display geographic data”.
To answer your question, Address or LatLong type columns provide a property for specifying the “optional Url for KML File”. See image

I did created a link with a https://www.webnou.ro/gal/webnou/NY.kml downloaded from New York - KML Boundary File Download
My app has these columns:
but when I open the KML map I get not the boundary I expected but:
Any ideea on how to fix it?
EDITED: I realized I was putting quotes around the URL. Once I removed those, using the US states layer file, the KML layers showed up as expected.
I tried again the file you provided https://www.webnou.ro/gal/webnou/NY.kml and it does not show up. There are limitations and I am wondering about this one:
”Maximum number of total document-wide features: 1000”
I don’t know what counts as a “feature” in the KML files. This file is not very big but there are a LOT of coordinates specified. I am wondering if a restriction is being violated and that is why it does not show up?
You might try copying the file and then removing some of the Polygon objects to see if you can get anything to show.
*Disregard the below
I am also having trouble getting the KML layer to show. I am not sure why. I even used the file in the knowledge base post. Maybe it has to do with how I am trying to reference it off the Google Drive?*
I have been in apps in the past that had KML layers already implemented. I have never tried to add a new KML layer - except when playing around with the feature years ago. I don’t remember needing to do anything special - in either case.
Can anyone else help with this?
