That’s not to say we won’t use SVG at all, though. It could be done purely with SVG, but at the time of writing, SVG rendering performance isn’t quite there yet, while canvas is hardware accelerated on most platforms. To make this map, we chose canvas for rendering for performance reasons. Find him on Instagram, Twitter, Flickr and VSCO. The photography is courtesy of Dan Rubin who has travelled to Iceland and has taken some incredible shots that we used in the demo. Labeling, for example, is hugely important and takes a lot of time to do right.Attention: This is a highly experimental project and it might not work in all browsers. Then just a bit of cropping and cleanup, and it's done! That list, of course, vastly oversimplifies things, but it gives a good idea of everything that goes into a map. Label all the peaks, physical features, and towns one by one in Illustrator (no GIS data involved), and place them into Photoshop.(Shadows thus fall on roads as they would in real life.) ai file as a layer in Photoshop underneath the relief.
Export and style them with Illustrator, and place the. Add roads (from OpenStreetMap via Geofabrik's extracts) to the QGIS project.Generate and label contour lines from the DEM using QGIS, then export and add them as a Photoshop layer.Use some Photoshop tricks to make relief highlights a bit brigher and warmer-colored, and shadows a cooler color.Add water lines and polygons (via Census TIGER/Line) to QGIS, style, export, and add to Photoshop above land cover.It becomes a subtle base layer, not an essential piece of data. Heavily blur the land cover so that it's not harsh and pixelated.In Photoshop, add land cover, then the relief layer with a "multiply" blending mode.Reduce it to only a few colors (mainly, evergreen forest and "everything else") and export it with dimensions matching the relief image. Set up a QGIS project with land cover data.
Genereate a shaded relief image using Blender, per Daniel Huffman's excellent tutorial.Download a good digital elevation model from the National Map.
There's no single way to make a shaded relief map, but here's how this one came together: (The same is true of web maps, by the way: we write a lot of code for small design details that push beyond defaults.) Cartography is rarely a matter of throwing data into software and getting a map in return rather, a single map usually involves multiple tools and data sources, and a lot of attention to small details. It's satisfying to see a map come together piece by piece, as in the above animation showing the main steps and layers in producing this map.
