Snapping a line to a point before splitting was meant to ensure that the split point is really on the line. However, ST_Snap() does not always behave well for this case. It may shorten the interpolation line in some cases with the result that two points housenumbers suddenly fall on the same point. It might also shorten the line down to a single point which then makes ST_Split() crash. Switch to a combination of ST_LineLocatePoint and ST_LineSubString instead, which guarantees to keep the original geometry. Explicitly handle the corner cases, where the split point falls on the beginning or end of the line. |

Nominatim
Nominatim (from the Latin, 'by name') is a tool to search OpenStreetMap data by name and address (geocoding) and to generate synthetic addresses of OSM points (reverse geocoding). An instance with up-to-date data can be found at https://nominatim.openstreetmap.org. Nominatim is also used as one of the sources for the Search box on the OpenStreetMap home page.
