Re: [OSM-talk] How best to create a single point of interest online map with OSM data?
Overall CartoDB is working out fairly well. Here's an example: https://brycenesbitt.cartodb.com/viz/8385ca6a-49a1-11e4-ad81-0e4fddd5de28/public_map I've post processed ways into nodes as suggested in this thread. The cartoDB server side rendering is a big plus. Though it does still get laggy: try Europe. The popup formatting is not as nice as uMap. Both umap and CartoDB lag Fusion Tables here. Coloring dots according to an attribute is also easy in Fusion Tables, but more awkward here. The CartoDB example, unlike with uMap, is not live data. This map also shows quite graphically how many toilets are missing from OSM :-)! Bryce Nesbitt ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk

That is a known problem, which however can be solved by pre-processing the data. For example with osmconvert with --all-to-nodes (you will need to remove untagged nodes with grep after this).

It's not the same sort of thing as uMap, but for info the switch2osm leaflet example does include some information about getting data from an external source for the map viewport (so you don't try and display everything all of the time): http://switch2osm.org/using-tiles/getting-started-with-leaflet/ You'd presumably need to do something similar to thin out the POIs made available if there are too many in a given area.

Re: [OSM-talk] How best to create a single point of interest online map with OSM data?
It depends on what is slowing down: retrieving the data via OverPass, parsing that file, drawing the individual pins ? - retrieving the data can be avoided by caching in a GeoJSON file. I don't expect that clustering will help if this is the bottleneck - the two other parts depend on your machine, browser and JavaScript interpreter, although clustering helps improving the drawing, as one has to display less pins. Limiting the data to a certain viewport only helps when you start looking for POIs when you are zoomed in enough. If you don't do that, you'll see 30.000 markers when the whole world is viewed.

[OSM-talk] How best to create a single point of interest online map with OSM data?
* Ways disappear on the map (they don't get a pin: zoom in on the map to see two hidden toilets). This was a problem we had with the Mappa Mercia pub example. Turned out overpass can export centre points and following an update to uMap we posted a new guide: http://www.mappa-mercia.org/2014/09/extracting-centroids-from-openstreetmap.html Hope this helps. As for the issue of too many points, one option is to have uMap collect data dynamically (as per our guide) and restrict to only showing data when at a certain zoom level or above (with clustering at lower zoom levels).

http://cartodb.com has OSM Basemaps (via MapBox) It can do server side rendering of datasets like fusion tables does.

What is the difference between a point of interest and a single point of interest? Saying that a map will show multiple single points of interest seems like a contradiction.
