Hand-colored maps

Postby GroundquestMSA » Nov 21, 2014 6:11 pm

I know that some traditional cartographers sneer at color on a cave map, but lots of new SVG maps I've seen are colored. Was there anyone that colored maps in the days of old? Do they still exist? Can I see one? How was it done? Will a hand colored map look like a third grade art project? Is there any other way, besides color or the traditional symbols, to indicate bedrock and soil floors in the plan view?

I don't like the bedrock symbol. Or the dirt symbol.

You can do whatever you want when you are the cartographer. I make my water solid blue. I make my breakdown blocks light grey on the top and dark grey on the edges. On one map I am working on the soil is a brush with brown shading. Just make sure you key it out.

I don't know what I want. Waaaah. I haven't been able to create alternate symbols that look good. That's why I'm thinking of playing with color.

I don't like the flowstone symbol either. It's quite undignified.

AS long as you key it out, you can do whatever you want. Don't expect to win any map salon ribons, but I don't make my maps for salons either.

Check out the fern cave page on facebook. the different levels have different colors of shading, as does the blue spring cave map of tennessee. i don't like it but thats fine.

Traditionally, in missouri, if its blank, its bedrock. I rarely use the bedrock symbol. Everyone I ccave with knows blank on modern maps in missouri = bedrock.

Chad, do you differentiate between sand/dry dirt/wet soupy mud with color? Or with symbols for that matter?

After experimenting with different symbols for soil/clay as well, I inevitably went back to just a hash mark, of a sort. To me, Cobble is cobble. Breakdown is breakdown. Bedrock is bedrock. Soil/clay/mud/soupy mud/dirt is one in the same. sometimes less is more, I have learned that as well.

In the case of soupy mud, I will simply put a note on the map. There is noting wrong with putting notes on maps. Maps are for information. If there is a 100' long streach of boot sucking mud knee deep,t hen I will p ut knee deep boot sucking mud with an line running to the area.

IMO more people need to use notes to explain what is going on. If people ask too many questions about a map ive done then I feel I have failed as a cartographer. That is just me.

I am rather blessed with caving in a stated with a handful of world renowned cartographers and I ask them all for feedback regularly.

Amen. I like notes on a map. Sometimes I spend far too long trying to describe something with lines and symbols when I could do a much better job with words.

Agreed. Notes and cross sections. Use the plan view to describe the passage with symbols. Use the cross section to further explain what all of the symbols mean and use notes to really point out things there aren't symbols for.

Spending time to try and makes symbols for wood debris, coral fossils in the walls, mud thats deep, mud thats shallow. etc etc, is just too confusing. Notes are easier and can be brief and explain it "Boot sucking mud' is very self explanatory.

John Smyre drafted the map of Cagle Chasm, TN, in color in 1983. He made both plan and profile in color. The colors were used to designate
depth levels of the pit rather than speleothem symbols. I've seen some other maps that used color to designate levels within a cave. It can be useful when there are multiple levels that cross over and under each other. Without color, it can sometimes be difficult to know which levels are on top or bottom when a cave is very complicated.

One thing I'd note about color is to make sure not only that the hues are distinguishable (red, blue, etc) but also differentiate with value (light/dark) so that the "colors" still read as different if the map is reproduced in black and white. Hope that makes sense the way I wrote it.

Another reason people avoid colors is color blind people, at least for a finished map. Doesn't matter for survey unless the map maker is color blind.

Max Kämper's 1908 map of Mammoth Cave utilized color to distinguish between tiers of the cave. The clarity of his map makes it useful for navigating the historic portion of the cave to this day.
