In the army,
we kept our maps in a mapcase similar to this Did all the marking with either a grease pencil (older days) or marker, and cleaned with alcohol pads. map stays protected. |

Laminate and use dry erase marker or like others suggested grease pencils, don't wipe off as easily.
Or what I usually do, color photocopy, or even black and white if you don't need the detail, not waterproof, but keeps my originals nice and neat, and I can make lots of copies to put everywhere or give out, and if I draw or write on it, no biggie, just grab another one if you need it clean, or burn if you trying to keep others from what you wrote down. Just my thoughts, and how I do it. |

Look for military map laminate. You can use clear shelf liner as a poor substitute

I can't find them this second, but I had some markers I used to draw my course on the sectional charts, back when I was flying. They came in a few colors. You drew all over a paper map, and then used the other end to 'erase' it. Worked really great! Found them!. These are the shit, and I believe exactly what you're looking for.

My dad used to laminate all his maps, charts, sectionals, etc. with contact paper. Use either the good old USGI Skilcraft grease pencil or the Staedler Lumocolors. Be warned that the Lumocolors can stain the map if left on for a long time. You can clean it off but you'll always be able to see a faint image of what you had written.

I bought a laminator a few years ago for a few bucks on amazon and have had a topo subscription forever, so nowadays I just laminate everything, but before that I would often put my map in one of the large map cases that someone linked to above. Either way I have always used a skilcraft pencil to mark it up with, then i take a dab of alcohol or bug spray and just wipe it all clean when done.
My uncle who first taught me Land Nav was a former Robin-Sage grad, (II/5). For him it was absolutely out of the question not only to dare make a mark of any kind on your map, but he got me into the habit of not even allowing yourself to fold the map down at all as it would still possibly give away your past or current location, hence the map case. Now I just print out my topo sheets online and then laminate the back to back, punch a whole through the set and throw a ring through the map pages, my grid protractor and grease pen tied to a length of dummy cord. That way you also have a small length of cord available in case you want to take non linear measurements as well. |

Laminate and use map pens, keep map in ziplock when not used.
ALTERNATIVE Use a map overlay. Or use both. |

Just remember that if you are using any sort of colored light to view your map, it will wash out the same colored marker. For example, red light is a bad color for viewing a lot of maps, as some features on the maps are in red.
DIM light saves your night vision; the color is almost irrelevant compared to the intensity of light. That's why some folks make a point of commenting on how dim some flashlights can be made to run. |

Red is used more for the fact the light is harder to detect (I.E. not as easy to pick up at distance), not to save night vision. Quote HistoryQuoted:

Don't use red map markers if you're going to use a red lens and you won't be able to see red map features under red light. Madcap is correct about the use of red lenses over green or blue. |

Red light in the dark allows us to see details using the cones, but does not effect rods. The rods can remain dark adapted. Too bright of red light leaves after images from the cones though, so there is that. White light, effects both cones and rods. |

Quote HistoryQuote HistoryThat report seems to have little bearing on what we're talking about, and in the introduction, it even states that red light allows faster dark adaptation over any other color. So, really, it supports my position, which is based on the knowledge of how rods and cones work, and what spectrum's are visible to them and cause reaction. The entire write up is to support the use of low level white light so people can work inside, since only one person really needs to be able to look outside. So to answer your question, after reading up and seeing what I think, I think that the report supports what I know, and have learned. The report is centered around people that need light to work the majority of the time, and need to be dark adapted a minimum of time. Map reading at night, is the inverse, dark adapted the majority of the time (using rods to see) and only needing to see well (cones) to read a map for a short period. Red light allows the use of cones to see more detail on a map, while literally having no effect of the rods dark adaptation, meaning once the after image is gone from the cones (quickly), your night vision is the same as it was before you turned the light on. |

Fine for the Mil, but what about the non-Mil map user? A lot of maps accessed and used by civvies have red details in them. Forget about red light washing out a red map marker for a second. The red light will also wash out red details contained in a lot of commonly used maps. Can't avoid that problem by changing marker color. |

Familiarize yourself with the map in daylight, use a color that will show under red light to overlay key details for use at night, or, realize that maybe it's time to go bright, and use white light, and know that your night vision will be wrecked. If it's important enough to use light discipline, and to have to maintain night vision, it's probably important enough to know what's on the map already.  |

There's another, simpler alternative. How about, when using maps with various colored features (including red), one employs a flashlight capable of being easily set to emit very low amounts of white light? I think some call this a "moonlight" level of beam. Basically it's intended for close up-tasks, such as reading maps/text/instruments, and so forth.
This solves the problem of memorizing the map, solves the loss of night vision, solves the problem of red light washing-out critical map features, solves the problem of red light washing-out red map markers, and may even eliminate the need for a red light altogether, thus simplifying equipment needs. |

Because the amount of white light that would allow you to keep your night vision is so low it's barely above ambient, and with red light, you can have it bright enough to see detail (cones), while having ZERO effect on night vision?
The irony, is if you use dim white light, you have to keep it so dim that everything appears grey in order to preserve night vision long term. Anything above that level, is going to effect the low light sensitivity. As said, red doesn't have that problem, and it literally can't be seen by the majority of your eye, specifically the part you would be using for stomping around in the dark. |
