Small change not uploading

Posted by Georgie Cassar on 1 June 2010 in English (English)

I simply changed a street name on an existing item 2 weeks ago using Edit with Save. After hitting save, I still have not seen the name change in OSM. Is there something I am forgetting to do ?

Location: -34.837, 138.502

The tiles may be cached still, to help reduce load or your browser may be caching them to prevent wasting bandwidth, what street(s) ?

If you mean Dickenson Close St. I see this street with this name in zoom 17, but in zoom 18 (max) it is named "Victoria Road". This can happen when some tiles have been updated, but some not. You can force updating with steps:
1)Right click on image and select "copy link to this image",
2)Paste it into adress line and add in end of line "/dirty", like that http://c.tile.openstreetmap.org/18/231925/158165.png/dirty and press enter,
3)In some time this tile will be rendered with new data.

If you just change name and did not change any shapes, then this place is not scheduled to update.

I have noticed this behavior as well. I think all changes should result in an update. It seems wrong that only updates that change shape are updated.

There are 2 update way for mapnik:
1) a change that affects x nodes will be rendered immediately
2) if there is nothing to render the rest of the world gets a refresh. That means that every tile will be refrehsed from time to time.

Updating a tile for every small change may be a huge load issue. I think the current way is ok.

Thanks to all for your advice.
Clearing my temporary files in the browser fixed the issue. I have leant that updates may not be immediate, however its handy to know about the /dirty method.
