Hi  
Can you tell me what the other values of `spatial.precision` give in terms of actual precision? All I can find is the details for the default and 8, but no other details about how other increments of that value will yield.

> The default value is 11 which yields sub-meter precision; a value of 8 will give a precision +/- 50m.

Thanks

Hi,

This is a geohash level, you can see a good example table here with some explanations on it:  
[https://www.movable-type.co.uk/scripts/geohash.html](https://www.movable-type.co.uk/scripts/geohash.html)

If you're looking at trying out Stardog's geospatial support, I highly recommend this primer:

Cheers,

Thanks! So this would be the corresponding precisions (from the page you linked)

| n | width | --- | height |
| --- | --- | --- | --- |
| 1 | ≤ 5,000km | × | 5,000km |
| 2 | ≤ 1,250km | × | 625km |
| 3 | ≤ 156km | × | 156km |
| 4 | ≤ 39.1km | × | 19.5km |
| 5 | ≤ 4.89km | × | 4.89km |
| 6 | ≤ 1.22km | × | 0.61km |
| 7 | ≤ 153m | × | 153m |
| 8 | ≤ 38.2m | × | 19.1m |
| 9 | ≤ 4.77m | × | 4.77m |
| 10 | ≤ 1.19m | × | 0.596m |
| 11 | ≤ 149mm | × | 149mm |
| 12 | ≤ 37.2mm | × | 18.6mm |

I'm already comfortable with geosparql, though I'll probably be back with some performance related questions around making sure I get the query plans as efficient as possible

thanks again!
