This is probably due to you having an Aggregation set on the Data Explorer configuration:
It defaults to MEAN, but since we don’t really know what it means to “average” a GPS coordinate, the
All Data table leaves the values blank. You’ll also notice the MIN, MAX, and MEAN columns in the
Aggregates table are also blank, but FIRST and LAST are populated. This is because MIN and MAX are also not defined concepts for gps coordinates. The FIRST and LAST are simply the first reported gps coordinate and the last reported gps coordinate for each time window, which we do know, so we display them.
The likley solution is to change the
Aggregation drop down to NONE.
