UK National Grid Reference (NGR) Coordinates

In the UK a common coordinate format, are British National Grid References (NGR). This is a projected coordinate system that has 2 grid letters that prefix the numeric eastings and northings e.g. Cardiff, Wales = ST 18212 76515.

We already make use of the BNG Locator, but we also wish to add the functionality to allow a user to click a point on a map and have it return the NGR.

In the Portal for ArcGIS New Map Viewer, the Location widget has an 'Add conversion' feature to convert coordinates. How can this be expanded to accommodate our need for an NGR coordinate?



If this isn't possible, how else can we achieve the same end result?

@OliverIshmael Did you ever find a solution to your question? I'm using ArcGIS Online but interested to know what options there might be

@dcallaghan unfortunately there doesn't appear to be an ESRI solution. For now we have just added a button within our Portal that links to this external site: Grid Ref Finder
