Hi all,

I'm trying to add a custom measurement unit in OpenLayers 2.12. All that is available by default in OpenLayers is:

displaySystemUnits: {
  geographic: ['dd'],
  english: ['mi', 'ft', 'in'],
  metric: ['km', 'm']
}

I would like to be able to extend this and add a custom one to measure in miles only. For example, if measurement is less than 1 mile, say half a mile, display it as 0.5.

I don't want to go as far as editing the actual OpenLayers Measurement.js by adding the following as it is not scalable for future upgrades:

myCustomUnits: ['mi', 'mi']

Any ideas how I can extend OpenLayers to do the above?

Thanks Dimitrios
