[GRASS-user] Qn on 'exhibit scale' to print maps

Hi all,

I had someone ask me about how to print a map at ‘exhibit scale’. Basically, if a map scale is say 1 inch : 100 feet, they want to make sure that the printed map is such that the printed scale on the printed map is actually 1 inch in measurement.

I was told this is common practice in construction, design CAD work.

So i thought this was probably to do with setting the resolution (dpi) and size of the map image file (jpg) and experimented around. I was surprised to find that indeed i could not easily get the map printed the way i wanted. i ran into issues of printer resolution too (which i dont think has anything to do with the solution)

This is probably a dumb qn, but i’d appreciate an answer!

Thanks!
Vishal

Hi Vishal,
My rule of thumb is ALWAYS put a scale-bar on any map.
These days the map maker never knows how/where/on what their maps may be printed.

I know your query relates to a fixed one-off map print under controlled conditions, but my comment relates to weening map readers off numeric scales.

HTH,
Zoltan
