Is it ever ok to display elevation contour lines without labeling any of the contours directly? In particular if you already list spot elevations for mountain peaks and the contour interval?

Interesting question. How will the map be used? How important is it for the elevation of any particular point to be known? If the map isn't likely to be viewed intensively, then the labels may just add unnecessary clutter, and there may be an argument for shaded relief without any contours at all. But if there's any chance someone will need to know an elevation other than a spot height, it would be best to add some contour labels.

It's my Hart Mountain refuge map, which is currently just a demo map I use in my portfolio. I am trying to find a home for it with the volunteer group who work at the refuge. I started to update the map for them and that got me thinking about the contours. The map is geared mostly as a general reference map to the most commonly used main and 4x4 roads and other major refuge features.

I use both shaded relief and contours now. The SR looked odd until I dropped the contours on it. I want to add some contour elevation labels eventually but I probably won't get to it any time soon. I think there is some value in simply seeing the contours and being able to decipher relative elevation changes via the contour interval (e.g. where I am is 500' below that ridge, or this canyon trail descends 800').

I'll most likely leave them on there but was wondering what the general consensus was on this and if there are any examples of others doing the same.

This is the current version, an updated map will replace this a few days (but the SR and contours will be the same):

Looks good, but I can hardly see the contours. If you leave them on, maybe you should make them a little darker.

I'm going to lighten the relief image first and see if that helps the contrast. The image I linked above is just a down sampled jpeg for my online portfolio. The map is actually designed as a GeoPDF. The contours are subtle but clear(er) when printed from the main file and they lend extra detail when zooming in on the PDF.

Maybe I'll mock it up with no contours and see how that compares again. Maybe I'll like it this time! This is mostly a personal map exercise for my own experience since I don't think there will ever be a viable market or means to sell the map.

David,

The resulting effect is very nice - I would definitely keep the contours. I especially like the context it gives to the west slope of Hart Mountain. I have a collection of recreation maps that range from 1:100K to 1:150K, and they all have unlabeled contours with spot elevations. Love 'em!

Nice work!

Thanks Bryan. If you have samples or detail shots of your label-less contours feel free to add them to this topic. I like your avatar by the way! ;)
