Learn how to synchronize timestamps of two Geo Time Series and copy the locations from one to the other.
Imagine that we have a reference series without geolocation (called "reference") and a second series with geolocalized data (called "dummy").
We would like to copy the location of data points of the second series to the reference series, but there are no timestamps in common.

Random data generation
At first, for this blog post, we will generate random data:
NEWGTS 'reference' RENAME 1 10 <% 'index' STORE NOW RAND 100 * STU * - TOLONG // timestamp NaN NaN NaN // lat long elevation $index TOSTRING // value ADDVALUE %> FOR 'reference' STORE
NEWGTS 'dummy' RENAME 1 100 <% 'index' STORE // generate fake data NOW RAND 100 * STU * - TOLONG // timestamp 48.2 RAND + -4.3 RAND + NaN // lat long elevation $index // value ADDVALUE %> FOR 'dummy' STORE

The data process consists on:
- Fill the "dummy" GTS with timestamps coming from the "reference" GTS
- Interpolate values and locations for those new data points
- Copy the geolocation from "dummy" to "reference"
$reference $dummy filler.interpolate FILL COPYGEO
