I know many maps and GIS use SVG somehow, how do they choose their basis unit?
I've just been doing some low level SVG map wrangling, but I just used a 1200px canvas and a scale factor. I knew the exact real world dimensions of the original image, so you could work out the meters per px for a given image size in px.
