GeoServer - Render style of points based on URLs saved in a field of the table using YSLD

0

1

I am new to styling in GeoServer and was wondering if there is a way to style points in a table based on the external URLs defined in one of the fields in that table.

Let's say I have a table in PostgreSQL with 100 points and a field (e.g. link) of that table has the URLs of the images that I want to use to style these points in GeoServer. One unique URL can be used across multiple points and the 'link' field will define what image to use for what point.

I cannot use filter rule because we want to keep the style dynamic in the sense that if a new point is added that has a new image URL, Geoserver should just style it based on the URL in the field rather than defining a new filter rule in the style for that new image.

This sounds like a simple point with graphic except instead of using a literal URL (as in the cookbook example) you would use a property.

title: 'YSLD Cook Book: Point as graphic'
feature-styles:
- name: name
 rules:
 - symbolizers:
 - point:
 size: 32
 symbols:
 - external:
 url: $my_url_col
 format: image/png
