I've been asked to create an overview and 7 small 4 1/8 x 7" trails maps featuring select hiking trails within Mt. Spokane State Park. The maps will be included in a hiking guidebook, which will be printed in B&W. I've been given some instruction on trails symbology, and I'm having a little trouble. Before I show the client anything, I'd like to seek some input.
There are 5 symbol levels for the "trails" (plus additional road symbology), symbolized according to width as the client specified. However, each map in the guidebook will only deal with featured trails, rather than all trails in the map extent. The client wants the featured trails to be "highlighted" (his word) in some way using additional shading or heavier/darker (or lighter) lines behind them. At first I contemplated polygon buffering each featured trail by 10 ft (or 50 ft--whichever works) and having the buffer be stark white, or hatched...but this just seems like a terrible idea given the small size of the maps and the large number of symbols already. My thought is that there are already enough line symbols to confuse the map. For this reason, I'm trying to come up with some other way to ensure that the featured trails stand out and are "highlighted". Currently, I'm doing this by using larger, bold text with arrows indicating direction of travel for featured trails... but I'm not sure that this will be interpreted as "highlighted" or stand out enough to a viewer that doesn't know what he/she should be looking for. I will probably add a symbol for trailheads at the start of each of the featured trails, which should also help, but have not yet done this.
Questions: Is my solution for emphasizing featured trails using larger bold text effective? Does anyone have suggestions for dealing with this challenge?
Also, any other criticism that you all have would be valued. I need to ensure that: featured trails stand out, elevation/terrain is represented, and that park features are clear and legible. I'm only using ArcInfo 10 for this work.
Attached is an example of 1 of the 7 small maps, as well as the legend (which will apply to all maps, but which will not appear in or next to any single map, says the client).
