Cleaning up the Galaxy's bad data: An EDSM story.

The number of systems with missing coordinates has seemed fairly stable, but some do have more recent timestamps. It's been in the 2.6-something million range at least as long as I've been paying attention, in any case. ;)
Is there any information around about how the number of systems with estimated coordinates has varied over time? The systemsWithoutCoordinates file that I downloaded recently has 1,888,289 systems with an estimatedCoordinates field (out of 2,586,248 systems total, which as you say still seems fairly consistent with the 2.6 million you mentioned). At least those can be used to plot routes!

I started tracking it on 8th April this year (I was curious to see if my addition of the get-systems-with-no-coordinates-in-my-current-sector function to EDD would make a difference).

Since then we've been going down by 356/day on average - or about 20 years to clear them all....
 
Thanks, I haven't been tracking the trend, but that sounds about right. It's been in the 2.6 million ballpark for as long as I've been aware. My count is always a few days behind, but I have 2,586,688 missing coordinates in my database currently. The number drops to 2,352,915 when I ignore the "deleted" entries.

(Aside: For deletions, I only "soft delete" rows in the table by flagging them, and only get a chance to do that by syncing against the full dump from EDSM every once in a while. I do this manually once or twice a year.)
