An interactive map of central Cambridge's cycle network — separated tracks, painted lanes, shared-use paths and permissive footways, drawn over the street grid. Schematic by default; toggle the base map for context, or hide the streets to see the cycle infrastructure alone.
A detailed road map of Little Lujiazui (小陆家嘴), Shanghai's financial district — the street grid I mapped by hand as a child, here in its as-built form. The district frame is the parallelogram tilted with the street grain; Rectify squares it up with an equal-area map that keeps the side ratio.
The childhood hand-drawn map will join this section as its own layer once digitized.
The motorway network of the core 长三角 triangle — Shanghai, eastern Suzhou and eastern Jiaxing, enclosed by the Yangtze main channel, the Qiantang/Hangzhou Bay water lines and Lake Tai. All 高速 expressways alike in red, with trunk-grade 快速路 and expressway-grade 国道 as thin context; hover a way for its number.
Pick a city and edge length to render its map at exactly that pixel size, clipped to a circle. Toggle Railways to overlay OpenRailwayMap — useful for comparing the railway/metro footprint of cities at a common 17 km radius. Use Save PNG to export a lossless image of the visible circle.
