I am interested in knowing more about the accuracy of the plus code. I have been working with organisations who need to define locations for delivery and servicing applications. We have been looking at "What Three Words" as well, but I prefer your system and licensing model.
I am assuming that your system is based on the WGS84 spheroid? We are also hoping that we can add a fourth value after the "+" in your Code to bring the grid down to a 1mx1m. Is that a possibility? We also want to make provision for a process / system that is Geoid based - i.e. relative to specific tectonic plates. Why is this relevant? Our services are relative to real world places - i.e. places that are fixed to the Tectonic plates, not the WGS84 Spheroid - which as you know is fixed to observations external to earth - i.e. celestial bodies. Given that the average tectonic movement is a negligible 2-3 cm per year, this may seem unimportant. When the plate moves - as during or after earthquakes - the WGS84 coordinates will of course be different for the same place. In some places, especially around the so-called "ring of fire" movements can be as much as just around 10cm per year with jumps of several meters during earthquakes. Over a ten year period that makes a lot of difference. So my question is this - have you considered how to future proof your system?
