OpenStreetMap (OSM) highway, inland water, railway network, railway stations, aeroway heliports, aeroway runways, January 2016 (OpenStreetMap contributors, 2016 - http://www.openstreetmap.org; http://www.opendatacommons.org; http://www.creativecommons.org). Resampled (from pbf source data of varying resolution, typically comparable with SRTM1 at @ ~30 m) to 100 m and provided as 1201x1201 pixel tiles. Attribute values of 1 usually indicate the presence of the respective feature. All 'waterway' tagged features (streams, rivers, drains, etc., and tagging variants/ misspellings) in the osm data are denoted by this single attribute value. 'Waterway' and 'Natural' tagged features of quantifiable size at grid resolution (lakes, wetlands, riverbanks, and variants) are similarly denoted. Rail network features denote ('railway' tagged) lines/tracks only (i.e. commuter, light_rail, mainline, monorail, narrow_gauge, rail, station, subway, unknown, y, yes, branch, goods, railway, single_rail, track, wide_gauge, abandoned, disused, and variants). For railway stations, the osm tag for underground stations is inconsistently used in the source data. Some underground stations use the regular (overground) 'station' tag (denoted by 1). Where underground stations are tagged using the 'subway' tag this is denoted by an attribute value of 2. Similarly, aviation ('aeroway' tag) heliports are sometimes differentiated from helipads in tagging, the latter denoted by an attribute value of 2. Highway attribute values are denoted hierarchically as below: 1 WHERE highway tag = 'proposed' OR 'construction' 2 WHERE highway tag = 'path' OR 'footway' 3 WHERE highway tag = 'track' OR 'bridleway' OR 'disused' OR 'unsurfaced' OR 'abandoned' OR 'trail' OR 'byway' OR 'unknown' OR 'unmarked_route' 4 WHERE highway tag = 'service' OR 'services' 5 WHERE highway tag = 'living_street' OR 'pedestrian' 6 WHERE highway tag = 'unclassified' OR 'road' OR 'yes' 7 WHERE highway tag = 'residential' 8 WHERE highway tag = 'tertiary_link' 9 WHERE highway tag = 'tertiary' 10 WHERE highway tag = 'secondary_link' 11 WHERE highway tag = 'secondary' 12 WHERE highway tag = 'primary_link' 13 WHERE highway tag = 'primary' 14 WHERE highway tag = 'trunk_link' 15 WHERE highway tag = 'trunk' 16 WHERE highway tag = 'motorway_link' 17 WHERE highway tag = 'motorway' 30 WHERE highway tag = 'bridge' or 'tunnel' (used only where highways span coastal water bodies).
