Zoom level and building numbering #98

Open polly64 opened 2 years ago

polly64 commented 2 years ago

https://maps.bristol.gov.uk/pinpoint/ @edwardchalstrey1 @tomalrussell @matkoniecz Hi this Bristol Council site uses OSMM and the zoom level we want and the building numbering, latter presumably from OS AddressBase, Any thoughts re whether we can now also add these under the explorer OSMM licence as both have been raised as issues by users?

As in the example and work in progress on colouring-cities/colouring-core#710 we should be able to go up to zoom level 20 with the OSMM map tiles.

Building numbers are purely in the background map though, both in the Bristol example and the tiles we're using - so if we draw coloured-in building on top, they will be obscured.

We do have a number_labels tile layer which should be rendering the location_number data that we collect.

@matkoniecz can I check we are on max zoom as above for Loughborough?

Just adding Maciek's mnotes from 2020 - issue 85 in case useful 'The cached tiles for the type category, for further-away zoom levels (around 12-13 and lower numbers) are out of date. When zoomed in, more data is available and displayed on the map.

Analysis shows that the buildings that are visible in all layers were updated around October 2019, whereas the ones that are only visible on more detailed layers (zoom 13+), were updated in late November 2019. This suggests that between these dates there was potentially a change to the tile server code which prevented the tile cache from being properly invalidated upon the November edits.

The tile cache needs resetting (whether this affects only one category or all is unclear for now). The tile server code also needs investigating to find if the cause for this situation is still present'.

After additional analysis including performance measurements this was changed, and now all zoom levels are cached (I can track down commit if needed)

That was done before planning permissions presentation when performance was a concern.

Tile cache was fully reset recently.
