It is a beautiful map, well done. There are many more aspect that I like with this map then I dislike, but I will just mention the ones that seemed odd/stood out to me. All of these comments are based on viewing your pdf map at 100%, except for sometimes I zoomed in even closer to get a better look. Finally these comments are based on if this map were to be viewed at 100% only (which it is not).
Definitely intended to be viewed zoomed way in. I have found that PDFs do strange things to line work at full zoom. Very light lines, like the contours or rivers are beefed up by the PDF when zoomed out and only resolve to their intended appearance once zoomed in more. The lighter or thinner the line the closer you have to zoom to see the real appearance. I think the Avenza app works with GeoTIFs as well and I may have to experiment with that format to see if one is better than the other for this maps use.
I'll start with your water features, is the color that you used an sRGB equivalent to 100% cyan? They seem pretty saturated to me, compared to your subdued hypsometry. Your labels for the water features seem very similar in color as well. I typically utilize a similar strategy, however, in your case it makes them very difficult to read over the Alakai Swamp area. I think that subduing the swamp symbology would take care of that or you could just change the label's colors.
Yes colors are RGB conversion of CMYK. The stream lines and water labels actually have some black in them (90% c & 10%k), while the swamp pattern is actually a less intense C (not sure of the percent). I agree they could all be less intense.
The isohypse are way too heavy/thick. I like for them to be a grounded element and here they are a prominent figure.
I think that thinning the lineweight at least on the ones not labeled will help this (I'll sometimes bring mine down to .15 or even .1 depending on the printing). Again, your not printing so I would probably try a .1.
I think for the PDF I posted these were .4pt for the index and .2 for the regular contours. I reduced them later to .4 and .15 but will probably go thinner. The real issue though is what I described above with the PDF line resolutions and zoom level. Zoom in to the level you'd be at to view the trail and local area and everything looks much better.
At 100% the two colors delineating your state/fed boundary lines blend into one color. Furthermore this made them stand out to me. They became the highest element in the VH to me, not your trails. Around 200% zoom I could tell that each line was in fact three colors, a solid green line with a semi-transparent color on each side. It was confusing to me at first. Maybe if you labeled the unit with a similar color as your boundary line it would help to clarify this?
Same issue as with the contours. I am torn about how to label these though. I usually label areas int he same color as the boundary but that seems to clash with the relief in some areas. I have also considered labeling along the lines themselves instead of inside the area. There are no real jurisdictional changes that occur between areas for most hikers so I could leave these off, but they do describe hunting areas and that may be a potential use for the map or serve as a guide to explorers who want to know when they are in a hunting zone. I may increase the outer lines transparency.
Check your point markers, they have all shifted. A majority of your peaks are rendered in topographic lows. This may just be me, but I am not a fan of labeling waterfalls w/o an associated stream. I would only do that with springs.
I don't see all of them having shifted, but some do appear to be off what would look like the nearest prominent peak. I'll have to double check against the topo. What may be happening is that in many cases ancient Hawaiians would have named a local spot not based on its prominence but for a large boulder or rock that lay near by (spirits often reside inside these features). I'll check the waterfalls too. I need to fill in some more stream names in some places.
It seems like a lot of your trails traverse lakes in the Alakai Swamp area, is that really the case?
Their not lakes really, more like bogs and where the trail passes through them it's raised by a board walk or built up earth paths. I should look for another symbol there or just convert to swamp.
Just noticed Monoa Str. (abbreviated) Stream is spelled out on the other.
Good catch, I need to convert all to Str..
Thanks for the comments Kru.
