Revisions

Version 22

Fri, 13 Oct 2023 10:53:43 +0200

Updated status to hidden as the dataset is not deprecated but will not be used in the final grid.

Version 21

Tue, 10 Oct 2023 15:03:47 +0200

Added the final mask which will be used for all future updates as a supplementary file.

Version 20

Mon, 26 Jun 2023 10:05:21 +0200

Data has been deprecated in favor of splitting up the dataset into several smaller ones based on TID of individual points.

Downloaded latest data from CHS on 2023-06-12, converted to 3996 and decimal coordinates, and masked all previously removed points (122000). Created a supplementary file of all previous masks and the unedited download file. Updated preprocess script and metadata; filename, filesize, originator, provider, srs, url.
