Kvadraturen roads were already very well mapped and named so I focused on recording the particulars of all the pesky one-way streets, streets only permitted for buses, turn restrictions and the like. Even if Kvadraturen is essentially a grid, many routes through the city center require surprisingly massive detours and will only be routed correctly if all the finicky driving restrictions are available in the map. On one particular occasion, I only moved 400m if measured in straight line while my car speedometer read 2.4 km due to all the detours.
I've also added restaurants, cafes, hotels (not nearly half), ATMs and other useful stuff for tourists. It's kind of embarrassing - I've walked, driven and cycled these streets ~500 times but I was still very surprised to see how many details there are to map when you're really paying attention.
I also surveyed and named the streets in the small residential area north of the grid. Here there's the funny case where one end of a short 50 m street has one name ("Fergefjellet") and the other end a different name ("Sigurd Gundersens gate"). How did it end up like that..?
Ok...ok... really too much rambling now. Next time: Outskirts of Kvadraturen and, hopefully, much more.
