The next step in my mapping project is to significantly enlarge the map.
When I first decided to map Ongus, I had no real intention of printing the final map and for that reason I didn’t give all that much thought to its final dimensions. What I wound up going with was a height and width for the map which fitted relatively nicely into the CC3+ drawing window on my computer.
I did wind up printing the original version, and to make it fit into the dimensions I wanted I wound up adding a band to the bottom of the map that included a heading, but was mostly white space.
With this map, I know I am going to get it printed at either A2 or A1 size – fortunately a feature of the ISO 216 paper sizes which most of the world outside North America uses is that whatever paper size you use in the A1-A10 series, the same height/width ratio remains – √ 2/1 or approximately 1.414 – so I have to enlarge my map – increase its height – to change its height/width ratio to the desired value – or in this case, it’s width (x-axis)/height (y-axis) given my maps landscape orientation as opposed to portrait.
My existing map has a width of 8890 and a height of 5080 units (in this case, those units are feet – while for most things I prefer the metric system, for a medieval based map, I chose to go with older imperial units (even though those also differ from the ones used in the middle ages). That is a 1.75 ratio. To get the desired 1.414 ratio or close to it, it’s simply a matter of dividing my maps width by 1.414 to find out the desired height – this yields a height of 6287 to the nearest foot – for convenience (because at many points in my mapping I am using a 10 foot grid), I want to round that to a nearby multiple of 10 and I chose to go with 6280, because that means increasing dimensions and moving certain objects by a convenient 1200 units – the fact that my final ratio is 1.415 rather than 1.414 is negligible.
I have also noticed that when I use a blur effect to blend together the background of my map I am winding up with areas on the edges of the map where the background is not solid, but paler than I like. While there are probably more elegant ways of addressing this, I’ve decided the simple solution is to simply add an increased border to the map of 250 units on each side.
By moving the area at the bottom of the river, 1200 pixels downwards, I enlarge the river as well, which will mean remapping the Bridge of the City, but I’ve been wanting to improve that – one thing I have always liked about the medieval city of London (on which this city is somewhat based) is the existence of the buildings that lined London Bridge during the Middle Ages, and its drawbridge – making the bridge a more significant part of Ongus seems thematically desirable.
After making these changes, here is the result. The Bridge will need to be made anew.
