Hi all,
As I mentioned yesterday, I've been preparing a tool that would allow to
analyze changes in OSM data. This work is based on OWL although it
includes major alterations to the original code so it is not certain
that it should be called OWL anymore (Matt's opinion pending)...
Anyway, after I resurrected the database part I went to work on the
owl_viewer component and this is what I have to show you today:
http://suncobalt.dyndns.org:8082/map
It is based on the original owl_viewer with couple of major changes:
* There is no tiling of changes - it works based on the current viewport
- what you see is what you get in the changeset list and RSS feed.
* Full changeset geometry is shown for each changeset (marked in yellow).
* You can click on a specific changeset row to zoom to its extent.
* Right now it is limited to min zoom level 12 and shows max 100 last
changesets at once because of server overload issues.
* Changesets that contain only changes on relations or only removals
currently don't have any geometry in the database thus will not be
display on the map - it is on the TODO list.
* The database contains changesets starting from 2012-10-11 11:59:01.
* Data replication on the server is currently at 2012-10-12 16:58:57 and
going (very) slowly so new changesets are appearing.
This is mainly an initial experiment to see if current database schema
scales to large number of changesets.
