This « Blue Map Style » colors Water and Waterways features and characteristics in JOSM. A better distinction of these various objects facilitate editing. Rendering of Water and Waterways features (natural and man-made) looks alike the carto-css style (images imported from the various carto-css projects).

This Blue perspective let's concentrate on water features while other objects are grayed. The Waterways style is downloaded and activated from the Mappaint Preferences dialog box. To view simultaneously other objects, you can activate simultaneously other Styles. Assure that you place them below in the list of Styles to assure you dont hide the Waterways features.

Waterways features

• stream, drain, ditch, wadi
• river, canal, pressurised water and pipeline, fairway, tidal_channel, fish_pass, derelict_canal, historic=canal
• symbology for tunnel, bridge, intermittent, abandoned features

Other Waterways features

• nodes+way+area for weir and dam

Natural Water

• ways : coastline
• areas : natural =water, waterway=riverbank, wetland, glacier, sinkhole(+node)
• wetland : bog, fen, marsh, mangrove, reedbed, tidalflat, wet_meadow
• coastal water features + tidal=yes : beach, sand, shingle, mud, reef, shoal, bare_rock

Other Water features

• harbour, dock, drydock, water_tower and reservoir (node+area, water and sewage), pier (way + area)
• landuse=salt_pond
• intermittent water, flood_prone areas

Flags

• flags potential errors with red triangles (ie disconnected segments, transition from river to stream, unclosed polygon)

Setting options

(click with the right button mouse on the Waterways Style (Mappaint window - list of styles)

• setting option to « Show Flags - potential connection errors » (true by default)
• setting option to « Show Water / Waterways names » (false by default)
