### Change Log for Node-RED Worldmap
- v2.8.8 - Change length of speed leader to show where you will be in 1 min if speed in m/s
- v2.8.7 - Delay start of ui widget.
- v2.8.6 - Better checking of type property before guessing it's geojson. Issue #153
- v2.8.4 - Add addToForm(n,v) option and $form - to make contextmenu form submission easier.

Optionally set `"wms":"grey"` to set the layer to greyscale which may make your markers more visible.
**Hint**: if can use a docker container like https://hub.docker.com/r/geodata/mapserver/ then assuming you have the mapfile 'my-app.map' in the current working directory, you could mount it as:
```
docker run -d --name mapserver -v $(pwd):/maps:ro -p 1881:80 geodata/mapserver
```
then the url should be of the form `"url": "http://localhost:1881/?map=/maps/my-app.map",` where *my-app.map* is the name of your map file. A quick test of the server would be to browse to http://localhost:1881/?map=/maps/my-app.map&mode=map
