Dear List, I have some issues getting river boundaries out of OSM data when using GDAL to read e.g. an OSM xml file downloaded via the overpass API. Using e.g.:
>ogr2ogr -t_srs EPSG:3857 -f SQLITE -dsco SPATIALITE=YES --config OSM_USE_CUSTOM_INDEXING NO map.sqlite map.osm >ogrinfo --version GDAL 2.1.0, released 2016/04/25 Specifically I have been trying with the River Thames in London. For some parts of the river it works, and I get features in the 'lines' layer with waterway='riverbank', that are closed. But for many locations I get no features (lines or multlipolygons) that can be used to bound the river - links to some images and OSM data below. When running the ogr2ogr command, I do get an errror: ERROR 1: Too many tags in relation 62149, which is not unusual though.. However, the osm2pqsql tool seems to be able to handle the various cases and I do get nice polygons bounding the river. Hope that someone can shed some can shed some light on what can be done. Is it a complex situation, that OGR currently cannot handle, or can I tune some parameters or the osmconf.ini file to be able to handle these cases? I am aware that rivers can be tagged in several different ways.
