Some units are moving and regularly registering it location. Each of these register events corresponds to row in a csv-file. This row contains fields:
id
(unit identifier),lat
,long
(event location),time
(event time inyyyy-MM-dd HH:mm:ss
format, it can be a number of seconds from 1970 if it really matters)
I need to create a polyline layer in QGIS from this csv-file, that represent routes of the units.
