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 datapoints of the second series to the reference series, but there is 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 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 datapoints
- Copy the geolocation from "dummy" to "reference"
$reference $dummy filler.interpolate FILL COPYGEO

It is time go back to the basis. The FETCH function allows you to extract your data from Warp 10™ in different manners.
Warp 10 works with UTC time for data points, but, you can easily convert UTC times in your timezone.
