Data have been provided to NEODC via a number of routes:
Most data up to 2005 was provided directly from ARSF flight team (ARSF-Ops) or Andrew Wilson at CEH, on various media.
Data since 2008 was mostly transferred to NEODC from ARSF-Data Analysis Node (DAN) in Plymouth via rsync.
Data for 2006 - 2008 were provided partly from ARSF-DAN, partly from ARSF-Ops, and some from Andrew Wilson.
Data from the ULM LiDAR instrument was provided, via FTP or on media, from ULM Cambridge.
Scanned aerial photographs were provided by Bluesky Ltd, who carried out the digitisation, on LaCiE disks.
Some data ("user_provided") was sent to NEODC by ARSF data users.
