I have the polygon data for the city of Kamloops in QGIS 3. When I try to copy features of this polygon and try to paste it over here: https://arthur-e.github.io/Wicket/sandbox-gmaps3.html I don't get the shape I am looking for, instead I get individual points.

This is how the city of Kamloops looks in QGIS 3: enter image description here

This is the MultiPolygon data for the yellow neighbourhood:

When I plot this over here: https://arthur-e.github.io/Wicket/sandbox-gmaps3.html

This is what I get: enter image description here

I am not sure what's going on there, is there something wrong with the data?

    Probably wrong crs, try wgs84 (epsg:4326). – MrXsquared Jan 8 at 0:26
  • What coordinate system is your polygon data in? – Cezar B Jan 8 at 0:26
  • thanks @MrXsquared , you are correct. I resolved the crs and it worked! – hky404 Jan 8 at 19:55

I tested your multipolygon WKT with OpenJUMP and it seems to be valid. The problem you faced is that the site https://arthur-e.github.io/Wicket/sandbox-gmaps3.html assumes that WKT is using WGS84 longitude-latitude coordinates but your WKT is in some other coordinate system. If you want to use just that site for visualizing you data you must first convert your layer into EPSG:4326 with QGIS.
