I am writing because I am facing a problem in exporting in .CSV format.
I have my defo image, and I go to File–>Export --> CSV and set all the parameters, also choosing only Abstracted Metadata in Metadata subset, selecting only a small area of the entire image, and my estimated raw storage is very small, more or less 100 Megabytes, but when I run the process, the final output can be also more than 20 Gigabytes! How is that possible? Can you please tell me how to export easily metadata infos?
the CSV export is designed to write raster values into a CSV, probably not for metadata records in the first place.
When I try the export on a larger raster, disable all outputs except for AbstractedMetadata, I end up with an empty table subset_TDM1_ifg_clip_flt_flt.csv
If you want an entire set of metadata, you can open them, hit Control+A (to select all records which are displayed), then open a text editor and hit Control+V (to insert them). This gives me such a file metadata.txt
