setting line thickness and colour for geojson

[mattpgreen]

hi, is there a way to set the line thickness and colour for geojson items - currently it appears to default to 1px which doesn't stand out from the background

Hi @mattpgreen, sorry for the late answer. The easiest way to style geojson features in terria is to use advanced style editor.
Here is a screen recording of how you can achieve changing the line width (ignore the copy error it is because the clipboard can only be used with https)

I used https://gist.github.com/zoran995/d3767b3fc3ddee6bf39b7e1f9102b559 as a sample data set, and this is a sample style definition

{"styles":[{"id":"User Style","color":{"colorColumn":"name"},"outline":{"null":{"width":5}},"hidden":false}],"activeStyle":"User Style"}

You just need to merge this style definition in catalog item JSON
