The river "IJssel" in The Netherlands, nearby "Zwolle" is drawn as thin line. Other rivers like the "Vecht" also nearby "Zwolle" are drawn in a normal way. The river is normally drawn on www.openstreetmap.nl and in Osmand. So it is not a mistake in osm.
I made two almost similar screendumps that shows the ferry on the "IJssel" (lon: 6,125 lat: 52,392) the first screendump is made from mapfactor navigator: shows the 'line' the second screendump is made from osmand: shows the 'river'
Is this the result of a setting or is there a fault in the mapfactor map????
I still have this issue with some of the rivers in the UK river Thames for example, I have updated to latest version of maps and app (android) does any one know a fix.?
