Fritz! (And everyone else, but especially Fritz!) That's brilliant, thank you! I really, really appreciate the time and thought you put into this answer. It is gold dust to me.
You've talked about and explained a number of the questions which I was puzzling over in the process. E.g why use circular gauges for some data and linear for other data?
The log scale on the pop values was a bugger, I tried a number of visual solutions which all proved to be unworkable but the one that worked the best, I found was to use descriptors like hundreds and millions so the person reading it would instinctively know it was a log scale without having to be told it.
I am so with you about the Earth Normal triangle drawing the eye more than the indicator and suggesting that it is the measurement indicator rather than the 'fill line'. I was kind of hoping that this would become obvious if people looked at more than one meter.
I went back to the drawing board and asked myself what these things would be used for, and came to the conclusion that it would be cool to have two levels of detail. One for sub-sector hex maps and another for player handouts. The first gives as much information as I could squeeze into a hex-map which players would need. Also I wanted to work it into the existing Traveller syntax and vocab rather than using new symbols for everything which people would find confusing.
Going through this exercise made me appreciate how elegant the Traveller Map is from a design point of view. The symbols retain their coherence down to a very small size allowing the user to look at a large area.
So the extra information provided in my enhanced sub-sector map is:
1. Is the outside environment hazardous? (Will I need a vacc suit?)
2. What are the approximate law, pop and tech levels? (memory tools: the WHITE heat of technology (Tech) / The BLACK cap a judge wears for a death sentence (Law) / A planet with a huge number of gray people (Pop).
3. What is the approximate size of the planet? I tried so hard to do this visually by varying the size of the planet diameter itself but this resulted in the larger planets interfering with legibility of the symbols around them.
4. What is the government type? Here I found 3 letter call signs made the gov type very easy to remember. I only had to read the Gov types once or twice and the 3 letter call signs brought them to mind immediately.
I think the map is still legible, but I would be grateful for comments.
So that the Enhanced Sub-sector map.
-----------------
The Second way of presenting the data (for handouts or for scenarios) is to pack as much data as possible to supplement each of the UPP numbers and giving each number its own graphic. The is really no need to be so economical with space with presenting this data. So the UPP number acts a summary of All the information in its related graphic. I've only just started this but I think there will need to be data which is not included in the UPP as well, (how many planets in the system? How many Stars? etc). It also needs to look attractive, so I'm thinking that something like an instrument panel look will catch the eye.
Fritz, I would really welcome your continued feedback!
