Topic: Searching against GIS boundaries - WKT

Hi,

To do a spatial search against one's own GIS polygon on the Atlas, Well Known Text needs to be pasted into a box on this page https://records.nbnatlas.org/search#tab_spatialSearch.  Has anyone tried this?  I have to say I had never even heard of WKT until I found it on the Atlas.  Has anyone else done this on another website somewhere perhaps?

Thanks,

Re: Searching against GIS boundaries - WKT

Hi Tom, I vaguely recall wkt is essentially a list of plain coordinate pairs. We use it in done programs and web services. Not at work yet, I'll look into it of I get a chance today (assuming you don't get a response in the meantime!)

Hi Ben,

Thanks very much.

Since I posted this I have had a go.  I got a WKT plugin for QGIS which generates the list of coordinates as you suggest, and which I then pasted into the Atlas. After pressing the button, it didn't appear to do anything, although I suppose it could have been doing something without it being obvious.

I think i'll try again but with a simpler polygon.

That page is broken. There should be a map showing before you ever paste in your WKT I think. There are various JavaScript errors which need fixing before you will be able to anything with it.
