[HOT] Plus code grid service

We're really excited to launch a free plus code grid service at
https://grid.plus.codes

(Plus codes is an open source algorithm to combine location with locality
names, so that you can have address-like references in places where street
addresses don't exist, like this school in Ghana: 8MF9+5C Sunyani. Plus
codes are displayed and supported in Google Maps as well as some other
apps.)

One of the strengths of plus codes is that they are based on a grid. Up to
now, the only way to visualise the plus code grid was with the JavaScript
grid overlay library, and that only worked with Google Maps.

The grid service that we have just launched means you can fetch the grid
and overlay it on top of your map using any library or application that
supports TMS requests, using either GeoJSON or image tiles. This could be a
GIS application, or a map that uses the Google Maps, Leaflet or Open Layers
libraries, etc.

The service also produces KML, making it possible to view the grid using
Google Earth. Just download the file at https://grid.plus.codes/pluscode.kml
and open it with Google Earth, and it will draw the grid whenever you move
the map.

Whatever format you choose, the level of detail of the grid depends on the
zoom level. If you zoom in, it will show more precise grid levels. The
image tiles display the plus code for each grid square, the GeoJSON format
includes that information and the KML format displays an info bubble when
you click on a grid cell.

For more information, see the website https://plus.codes or our GitHub
