There are lots of extra options you can specify as `msg.options` - see the <ahref="https://github.com/spatialillusions/milsymbol/tree/master/docs"target="mapinfo">milsymbol docs here</a>.
### Buildings
The OSM Buildings layer is available in the layers menu. You can replace this with a
building of your own by sending a `msg.payload.command.map` containing an `overlay`
and a `geojson` property. The geojson property should be a GeoJSON Feature Collection
as per the OSMBuildings spec. For example in a function node:
var geo = { "type": "FeatureCollection",
"features": [
{
"type": "Feature",
"properties": {
"color": "rgb(0,0,255)",
"roofColor": "rgb(128,128,255)",
"height": 20,
"minHeight": 0
},
"geometry": {
"type": "Polygon",
"coordinates": [
[
[-1.356221,51.048611],
[-1.356039,51.048672],
[-1.355765,51.048311],
[-1.355937,51.048237],
[-1.356221,51.048611]
]
]
}
}
]
}
var m = {overlay:"Golf Clubhouse", geojson:geo, fit:true};
**Note**: the object you supply will replace the whole buildings layer. To delete the building send a msg with a name and the building property set to "" (blank string).
#### Buildings 3D view
A 3D map view has now been added as **worldmap/index3d.html** using the mapbox api - the msg can support `msg.command.pitch` and `msg.command.bearing` to angle the view, for example:
The `icon` can be specified as a person, block, bar, or "anything else" - they will render slightly differently - all units are approximate. They will be positioned at the `lat`, `lon` as normal but also at the `msg.payload.height` - where height is in meters above the surface of the map (which may or may not relate to altitude...)
`msg.payload.icon` can be
- person : 1m x 1m x 2m tall
- block : 5m x 5m x 5m cube
- bar : a bar from the surface up to the specified minHeight
- (else) : 1.5m x 1.5m x 1.5m cube
in addition existing male, female, fa-male and fa-female icons are all represented as the person shape.
`msg.iconColor` can be used to colour the icons.
**NOTES**
- There is currently no way to add labels, popups, or make the icons clickable.
- The 3D only really works at zoomed in scales 16+ due to the small size of the icons. They are not scale independent like icons on the normal map.
- As this uses the mapbox api you may wish to edit the index3d.html code to include your api key to remove any usage restrictions.
- This view is a side project to the Node-RED Worldmap project so I'm happy to take PRs but it probably won't be actively developed.
### Areas, Lines and Rectangles
If the msg.payload contains an **area** property - that is an array of co-ordinates, e.g.
**ranges** can be a single number or an array of arc distances from the marker.
The **pan** is the bearing of the centre of the arc, and the **fov** (Field of view)
specifies the angle of the arc.
Defaults are shown above.
### GeoJSON
If the msg.payload contains a **geojson** property, and no **lat** and **lon**, then rather than draw a point
it will render the geojson.

Other optional properties (see below) can be used to style the geojson "outside" of the feature itself.
Often geojson may not have a `properties` or `style` property in which case you can specify some global optional properties (see below) in order to set some defaults for the geojson object.

### Arcs, Range Rings
### Drawing
You can add supplemental arc(s) to an icon by adding an **arc** property as below.
Supplemental means that you can also specify a line using a **bearing** and **length** property.
A single *right click* will allow you to add a point to the map - you must specify the `name` and optionally the `icon` and `layer`.
**ranges** can be a single number or an array of arc distances from the marker.
The **pan** is the bearing of the centre of the arc, and the **fov** (Field of view)
specifies the angle of the arc.

A single *right click* will allow you to add a point to the map - you must specify the `name` and optionally the `icon` and `layer`.

The `icon` can be specified as a person, block, bar, or "anything else" - they will render slightly differently - all units are approximate. They will be positioned at the `lat`, `lon` as normal but also at the `msg.payload.height` - where height is in meters above the surface of the map (which may or may not relate to altitude...)
If you select the **drawing** layer you can also add and edit polylines, polygons, rectangles and circles.
Once an item is drawn you can right click to edit or delete it. Double click the object to exit edit mode.
`msg.payload.icon` can be
- person : 1m x 1m x 2m tall
- block : 5m x 5m x 5m cube
- bar : a bar from the surface up to the specified minHeight
