Get and change reference point.

[bhuvankumaru]

Hello,
I have been using SARVey with MiaplPy and the results look very interesting. I would like to compare my results to the ground-based instruments. For that I would like to know:

1. How can I get the information of the reference point/pixel and how can I change it. I would like to change it to a stable ground station I know.
2. How to query to extract the timeseries of a particular point if I have the coordinates. For now, I am querying with the .shp files which is arduous, but is there a way to do it using p2_*ts.h5 and coordinates_utm.h5.
   Thank you!! Any directions or suggestions to contribute to the above issues are appreciated.

Hi @bhuvankumaru,
great to hear that you are using SARvey for your application!

You can use the sarvey_plot script to visualize the time series interactively and change the reference point when activating "Select Reference"-button and clicking right-click on a pixel.
Selecting a reference point during sarvey_export is not yet supported. If you are interested, please add an issue with a description of the feature. Perhaps you might consider adding it yourself? Let me know if you would be interested and if you need any support ;-)

SARvey does not provide a feature to query for the time series by coordinate. However, we have developed the free InSAR Explorer Plug-in for QGIS that provides an easy visualization of time series from various InSAR time series softwares. I hope it reduces the effort for you when querying time series. In case it does not fullfil your needs, please add an issue at the InSAR Explorer GitHub Repo.

Best, Andreas
