Hey Matthias, are you aware of the difference in google earth (kml) of TimeStamp and TimeSpan ?
it might be that your data is for points in time, not spans, so when you look at a point in time between 2 data 'points in time', there is no data. make sense ? hence the slider in GE needs to be a range or the data needs to be a series of non-overlapping timespans. not sure if its possible, i've never tried to get GS to be so specific with the time slider. -i Le 21/03/2011 09:40, matthias.spe...@bkw-fmb.ch a écrit : > Hi List > Here's what I'm trying to do: I have a PostGIS view with hydrological > runoff measurements on four gauging stations.
