[PLUGIN] - Google Maps Geometry/Drawing + W3W

Perfect! That works! I’m drawing some pretty complex polygons must be about 42,000 coordinates total. Where can I find the section to remove the white circle? They are slowing down the page speed:

This is such an awesome app and your Technical Support is the best I’ve encountered.


Nice! and no worries with support, it helps me make the plugin better.
So those white dots (vertices) appear when the shape is editable, set the “Editable” option to No and they’ll disappear.

@pork1977gm I figured it out, the Change Shape Properties was set to “Yes” fixed that by changing to “No” and it’s good to go now! Thanks again for all your help.

Hi Paul,

I’ve been looking at your plugin and it looks fully featured (if somewhat overwhelming for me), so I though it would easier to ask the questions directly to you with my use cases…

  1. We have the polygons and multipolygons for every country in the world and would like to check when we send a message to a user if they are in the country of question (the use case for this is that the FCDO in the UK send country alerts to citizens) we want to be able to see when the alert is sent if the recipient is actually in country or merely 'following that country. countries can be polygons or multipolygons (think USA and Alaska or Hawaii not being close to the main body of the country)

(our polygons are long.lat,long.lat,long.lat and our multipolygons are long.lat,long.lat,long, lat**;**long, lat,long.lat,long.lat)
We want to be able to store in the database "in country’ or ‘out of country’ when an alert is sent to the user, and if they read the alert later (ie if they land in country) then we get an updated status to say in country, again this will be stored in the database we will not store their actual location.

  1. We have polygons again (single and multipolygon) from the environment agency in the UK and have created groups for all of these, we want to allow a user to use their current position or any given position and obtain a list of all the flood areas that are covering that point.
    (our polygons are long.lat,long.lat,long.lat and our multipolygons are long.lat,long.lat,long, lat**;**long, lat,long.lat,long.lat)

  2. we want to allow the user to generate a polygon or multipolygon shape and attach it to a ‘group’ so that when users are at a location or searching a location they can see what groups are avalaible to join - the use case for this is something like a festival when we want to create a boundary around a location that may not be postcode specific. - right now we get the user to optionally add postcodes to their groups, but I think the polygon is the way to go.

  3. we want to be able to show all the possible polygons on a map so that a user can drop a pin and see what’s avaliable and what’s nearby etc - think police force districts local authorities.

I’d be grateful if you could confirm and if so point me in the right direction.

thanks in advance


Hi Robbie,

If you can bear with me, I’ll come back to you on this. These types of questions always put my head into a spin, but what you ask for can be done.


No worries, speak soon


PS for others interested in some decent sources for polygons…

  1. our country polygons come from this URL (World Administrative Boundaries - Countries and Territories — Opendatasoft) there are loads of different data sources in there that make quite interesting datasets in there that may be of interest in some of the others on this trail.

  2. our flood area shapes comes directly from the environment agency here in the UK, the have some 4.5k of flood areas across the country and can be found here , again some might find this interesting. (http://environment.data.gov.uk/flood-monitoring/id/floodAreas?_limit=5000)

  3. we also have one for the met office, however it’s restricted by an API key, but if anyone is interested you can find out more here (Met Office DataPoint - Met Office)

question for the wider collective and users of the plugin,

I have a GEOJson file that contains multipolygons that produces this when displayed though the plugin…

however when I extract the coordinates and plot them onto a map I get this…

which looks like the ‘pen’ is not being lifted between moving from the last coordinate of one shape to the first coordinate of the next shape.

I’ve tried various things like having each shape contained with combinations of brackets eg…





does anyone know off the top of their head if it’s possible to have multiple non connecting polygons on the map and if so how did you delimit them?

Can you send me the GeoJSON file (or contents) to me and I’ll try and figure out what’s going on. I think it will be to do with the way the coordinates are being reconstructed again. If it’s large, email to pork1977gm@gmail.com

When you say… “when I extract the coordinates and plot them onto a map”
What action did you use to do that?


Hi Paul, I know you and I discussed this, but for the sake of anyone else on the trail that follows your work and may be interested in this for their own purposes.

The GEOJson was read in python by a script that I wrote, it then extracted all the polygon shapes and split each shape set by a ; and then saved this as a text file.

so you get x,y,x,y,x,y,x,y;a,b,a,b,a,b,a,b;c,d,c,d,c,d,c,d as a single line of test where each x,y or alb or c,d represents a coordinate pair that makes a closed polygon shape.

And as demonstrated when we use the shape coordinates in the workflow action and select the item split by (;)Random Item, we get each of the shapes.
