I just found out about geohash. The geohashTools package creates short hashes that can be decoded to return the longitude and latitude.
The createLocationID() function should be deprecated in favor of a new createGeohash().
Based on this post, the length parameter should be around 10 to get adequate precision:
- 9 => 4.8m at equator
- 10 => 0.6m
- 11 => 0.15m
- 12 => 0.02m
This change will impact all of the data archives but maybe not much else. The rest of the code shouldn't care how the deviceDeploymentIdentifier was created.
