adding Nautical milles unit to MeasureControl

[jef-maubert]

Thanks a lot for the MeasureControl plugin that I found very usefull !

This MeasureControl plugin includes "acres", "feet", "kilometers","meters" and "miles" as linear units. (Note : the "miles" unit refers to "Statute mile", of the British Imperial unit system)

Could it be possible to introduce also nautical mile (or "nautical") ? This unit is very usefull (almost mandatory) for sea navigation because it is directly linked to the distance between paralleles.

The Implementation could be a new item in the objects list of the unit.js file :

nautical: {
    factor: 1,0/1852.0,
    display: 'nauticals',
    decimals: 2
},
sqnautical: {
    factor: 1,0/1852.0/1852.0,
    display: 'sqnauticals',
    decimals: 2
},

Best regards

Hi @jef-maubert, I haven't tried this but I'm pretty sure you can do this with the standard options of the JS package we use underneath. See https://github.com/ljagis/leaflet-measure#units. It exposes a unit argument that you can try. Our Python wrapper passes on any keyword arguments.

For example:

MeasureControl(
    units={
"nautical": {
    "factor": 1/1852.0,
    "display": 'nauticals',
    "decimals": 2
},
"sqnautical": {
    "factor": 1/1852.0/1852.0,
    "display": 'sqnauticals',
    "decimals": 2
},
    }
).add_to(m)

Can you try if that works as expected?

T‌hanks a lot for your answer

Yes It works perfectly (I had just to quote the python dictionary field names )

Have a good new year 223 !
