OSM-Carto is a style whose purpose is to visualise OSM data to MAPPERS, do it quickly (fast feedback is essential). OSM-Carto also has a requirement to be easily deployable by almost anybody on any hardware. This means that pre-processing of data is impossible as per requirements (not a design decision). And without pre-processing it is impossible to have a cartographically sound map. So even while the OSM-Carto team is doing a terrific job and they do have people with good cartographic knowledge (like Christopher), but OSM-Carto does not have such a purpose - cartography. We're playing around with a small project striving to comply with cartographic rules - topo.openmap.lt - some data is updated daily, generalisation is done weekly. But you already get generalised roads, buildings, smart lines for waterbody labels as well as text size and letter spacing. This should get cartographic simplification for waterways this coming spring (not DP or VW, but Wang-Müller). So this can be done, but OSM-Carto is not the place to do it. Therefore if you want to have a cartographically sound map - you will need a separate project - separate rendering and stuff. You're totally right - for general (not mapper) use, minutely update is less important than cartographically correct representation. And also not everything has to be generalised, some parts could be updated very fast, some could be updated weekly or even monthly. Segmentation of data could also get more attention (re-calculating only the parts which need re-creation). Such tasks could even push forward topics which are currently the target of generalisation and multiple representation group of International cartographic association - I really think OpenStreetMap has people and capabilities to have a say there. -- Tomas _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
