ATINDEX
gts
The ATINDEX
function consumes a Geo Time Series™ or a list thereof from the stack, looks at its index-th point and put on the stack a list with the timestamp, longitude,
latitude, elevation and value for the index
-th point of the GTS.
Since 2.1, the index can be negative. In this case the effective index is index + size of the GTS.
ATINDEX is available since version 1.0.0.
