a 3d view of an old topographic map, showing both the mountainous terrain and the bathymetry
Map titled: 'River Catchments of Scotland'. Distance from catchment boundary is shown as hillshaded topography and coloured using a blue-to-white colourmap. Large catchments, such as the Tweed in the Scottish Borders, Tay in Perth and Kinross, and the Spey all appear as large depressions in the landscape with their catchment boundaries appearing as ridges. The sea is depicted with a random scattering of blue-to-white dots.

A shaded relief map of iceland in shades of blue, on a dark blue sea, with points of red where there are 'Volcanoes, Geysers, Hot Springs & Saunas', which is written across the top in a viking-esque font
On a black background are many many, small wiggly lines, the lines are coloured by the direction in which they go, using a circular colour map. If you know that the lines depict where water would flow over a landscape, and that the colours correspond to the direction, one can see how this does resemble terrain, with lower elevations and river valleys depicted as empty space, and ridges are where the lines of different colours meet. It is messy and quite abstract
a ridgeplot style map, showing the topography of the Parco Naturale dell'Adamello-Brenta, with a smooth colour ramp from pale yellow in the foreground to darker blue in the far-field. Along the right and left edges are names of Rifugi (mountain huts) and lines leading to its location in hills
A map of the Cairngorms national park. Black background with white national park border. Within the national park the terrain is represented by colors ranging from black through dark purples to bright orange. Brighter colours represent regions that are 'more visible' than darker regions, as these areas can be seen from more summits. The resulting sum of viewsheds bears strong resemblance to the underlying topography.
A terrain map showing a hillshaded surface, coloured in blues and greens with blues denoting valley axes, and greens ridges
A map showing the UK and Ireland on a white background, the land is covered in a hexagonal grid, with each cell coloured using a the bivariate color scheme. Cells that have: neither hills nor water are in pale grey; lots of hills and no water in orange; lots of water an no hills in blue; and both hills and water in a orange-blue brown mix
A pseduo-colour terrain map of Laguna del Carbón. Low elevations are shown in progressively darker teal colors, higher elevations in darker browns. The color scale pivots at 0 m a.s.l which is white. This shows that the lowest point is _below_ sea level. The title text reads: 'Laguna del Carbón: -105m, gran bajon de san julian, argentina'. n the bottom left is an inset map showing the outline of South America, with an arrow pointing to southern Argentina
