I am asking about exporting time series in small area module.
Normally, I tick “mov”, “temp” and “model” to see the “real” movement happening there, and the model line is fractional (of course), and then press CSV.
But if I want to see the movement without the temperature component, I tick “mov” and “model” and expect the line to be straight (but it is not). And also, the time series are exactly the same except for a small change in lat, lon coordinates (this is what I do not understand at all).
Can you please advice me how to export time series without the temperature component?
sorry for the late answer, your matter highlighted a bug that needed some attention.
A new version is going to be uploaded in the next hours and the model mov/temper stuff should be fixed.
However, I do not understand what you mean when you say that there is a small change in lat and lon coordinates: what are you comparing to see the change?
If the comparison is between data exported after processing them with different options, this is the answer:
lat and lon coordinates are estimated using SAR coordinates + the height estimated from phase time series
if you process phase time series using different options for the movement, the height (which is jointly estimated together with the movement) will be slightly different.
as a consequence, also lat and lon will be slightly different.
if the movement model and the corresponding result is similar, the height change will be minimal (tens of cm) and consequently the lat and lon coordinates.
however, in some particularly complex cases, the choice of the model may be very important and the result very different…
Thank you, it works for my first AOI (I checked only if the model line is fractional or not).
However, in my second AOI, the model line is a straight line for most of the time, however at the end, it gets fractional again.
The weather data is complete here so that I do not understand it. However, as you answered me recently in a different topic, the weather data are downloaded first from a station near the whole image center, and then, when the area is cropped, it is re-downloaded from a station near the AOI. Then, maybe due to different versions used for the initial processing and the updates, the weather data for one AOI are from various stations (up to 3 but it is a different AOI/dataset, so not attached now), situated more than hundred km apart.
this effect was caused by the fact that the weather download (update) was performed between the small area processing and the display (geocoding), probably after save/load. So, it helped to reprocess it and display again and the lines are already straight.
