Solo
To claim this achievement alone, a geohasher must occupy the same hashpoint at two or more significantly different altitudes on the correct day.
The level of achievement gained depends on how many significantly different altitudes were reached that day.
Team
To claim this achievement as a team, the geohashers must simultaneously occupy the same hashpoint at two or more significantly different altitudes on the correct day.
The level of achievement gained depends on the number of hashers at different altitudes involved.
Positioning of the Geohashers
To be significantly different, the altitude difference must be at least 2 metres. This requires each hasher to reach their altitude independently (i.e., can't stand on each other's shoulders).
As long as both placements are within the margin of error for the hashpoint, the achievement is valid. The exact positions do not need to completely overlap as long as they would both be valid as independent expeditions.
Because GPS altitudes can be more inaccurate than lat/long positions, if the positions are shown to be a decent distance apart as shown in a photograph or other proof, the award can be claimed.
Proof
The standard proof for claiming a successful expedition is required.
Alongside this:
- A photograph showing how the stacking was possible (e.g. a photo of the outside of the car park, a photo of the bridge showing the path underneath), and
- A photograph of each geohasher at each level, or
- A photograph of each geohasher's GPS. As altitude measurements on GPS devices aren't very accurate, an alternative could be the GPS photographs showing the same time, or
- A convincing story if the GPS cannot provide proof (e.g. one geohasher was underground, one geohasher stood on a road bridge while another drove underneath).
Examples
- A bridge over land would allow for a Level 2 Multiple Elevation Achievement, as would a tunnel through a traversable hill.
- A hashpoint in a multi-story car park or a building staircase could allow for a Level 3+ Multiple Elevation Achievement.
- An apartment or office building could also allow for a Level 3+ Multiple Elevation Achievement.
- A simultaneous air and land geohash would be the ultimate multi-elevation, but this would be hard to prove!
