Online WKT and GeoJSON viewer

Question

I once found a great but simple webpage that has a drop-down with several text-based GIS formats such as GeoJSON and WKT, and a text box to copy/paste your data. The feature is then drawn on a world map. You can continue to add shapes on the same map.

Does anyone know the page, or any page where I can paste WKT and GeoJSON to see them displayed on a map?

That first link for OpenLayers is the exact page I was looking for!! Thanks so much - I'm not sure why I couldn't find it. – JPhi Oct 02 '14 at 03:07

Is it possible to specify the WKT as URL parameter, in order to share a shape with someone? – Eric Duminil Feb 13 '23 at 14:43

I created this little utility for a co-worker to plot multiple WKT or GeoJSON geometries on a Leaflet map. You can fork it and tailor it to your needs.

Fantastic tool, thanks! (if'd be great it could accept more than WKT object at once... ;)) – jjmontes Oct 01 '15 at 22:52

In case anyone comes across this question and needs to convert to/from Esri (ArcGIS) json, geoJson, or WKT, I created a small application called geometry-inspector. It is much like the listed applications in the accepted answer, but with the improvement that it supports Esri's json format.

Hope it helps someone!

For bash, I use my own script: https://gist.github.com/rajanski/4d2595c1fd4e35c19b4e1a02b4ed579f Pro: Geojson data doesnt leave local machine, good for confidential stuff.

Kepler.gl https://kepler.gl/demo

I can recommend the Kepler.gl demo where you can add your data in the following formats:

CSV, Json, GeoJSON or saved map Json.

As data privacy is a concern when using online viewers, they state:

*kepler.gl is a client-side application with no server backend. Data lives only on your machine/browser. No information or map data is sent to any server.

geometrymapper is what you're looking for. This Online Mapping Tool is capable of plotting WKT and GeoJson in different coordinate systems and colors. Really recommend it. (mirror https://vannieuwenhovej.github.io/wkt-geometry-plotter)

Avoid overt self-promotion. The community tends to vote down overt self-promotion and flag it as spam. Post good, relevant answers, and if some (but not all) happen to be about your product or website, that s okay. However, you must disclose your affiliation in your answers.. In practice this means any answer that recommends your own product must include something like "Disclosure: I am the [position] of [company] that develops/distributes this software". – PolyGeo Nov 20 '23 at 08:01
