I am doing bathymetry analysis, where I would like to color the contours one by one in the case land is rising (or sea level going down). There is a comprehensive explanation about coloring contours (Colouring areas between (vector) contours?) but it is not working since my contours never meet. I didn't success to change the .shp file with one contour to polygon correctly: I wanted the "land side" of the contour to become polygon, not other way round.
I have several .shp files of contours about the sea bottom topography, but the proper visualization is still missing.
I am using QGis 2.2.
