Coastline Update Frequency

Posted by porjo on 18 December 2012 in English (English)

The wiki says that the coastline is updated every few weeks, however I have a coastline edit that is still awaiting an update after 5 weeks!?

It'd be great if there was a page somewhere that indicated when the last/next update cycle is due to run so I could know if it's just a matter of waiting, or whether there is something wrong with the edit.

The wiki is wrong (nothing new there...) and it is generally rather less frequent than that - it's a manual process and is also dependent on trying to find a point in time when the coastline as a whole is not too badly broken.

A method to find out when the last update was is described here. According to that the current coastlines date back to October 29th.

This needs a solution. For the low zoom layers, not so bad, but when zoomed in, these updates need to happen more frequently.

Could the following process work?:

  • snapshot the coastline dataset at a point in time
  • the community can then correct errors in the snapshot. When an error is corrected, it should also be corrected in the main dataset (to avoid having to merge changes later), perhaps using an interface with a side-by-side window: on one side is the snapshot data, on the other is the main dataset
  • once all the errors are corrected in the snapshot, then that is commited to be rendered at the next available oppourtunity (this part could be automated?)
  • rinse and repeat

The onus is then on the community to correct the errors - the faster the errors get corrected, the sooner the coastline render gets an update.
