Ooh I like this: The National Library of Scotland has released Spy Viewer, a tool showcasing a set of historic which maps have been georeferenced so that they line up perfectly on top of the current maps. Using a circular spyglass interface you can watch the old maps peek through. Pictured below is a historic …

The Population Estimation Service is a Web-based service for estimating population totals and related statistics within a user-defined region. It enables users of a wide variety of map clients and tools to quickly obtain estimates of the number of people residing in specific areas without having to download and analyze large amounts of spatial data. …
In succession to Google Maps’s Quiet Transformation, a new – and very extensive and highly interesting – comparison by the same author. He start off by taking a look at the level of detail when it comes to buildings. But these buildings are more than just a pretty detail—they appear to be the foundation for …

Good intro by Arden de Raaij on setting up a basic Mapbox GL JS map with clickable markers that zoom upon getting clicked. Mapbox GL JS is a JavaScript library that uses WebGL to render interactive maps from vector tiles and Mapbox styles. It’s my favorite alternative to Google’s service and in this article I’ll …
Strava has released a Global Heatmap powered by Mapbox GL, plotting all locations where their users go run / go cycle / do water activities / do winter activities. The raw input activity streams data comes from a Spark/S3/Parquet data warehouse. This data includes every one of the 3 trillion GPS points ever uploaded to …
react-native-maps-directions – Directions/Routing component for react-native-mapsOne of the things I found missing in the aforementioned react-native-maps was the ability to route between to coordinates. Combining the feedback from the related issues on GitHub (#52, #778, and #929) I’ve created a standalone component that does exactly that. The MapViewDirections component can route between an origin and destination coordinate. As routing is …

react-native-maps – React Native Mapview component for iOS + AndroidOn a React Native project I’m currently working on, I’m implementing native (vector) mapviews. Gladly there’s react-native-maps by AirBnB to handle it all. import React, { Component } from ‘react’; import MapView from ‘react-native-maps’; class MapViewExample extends Component { constructor(props) { super(props); this.state = { region: { latitude: 37.78825, longitude: -122.4324, latitudeDelta: 0.0922, longitudeDelta: 0.0421, …

Color me impressed: MapSCII is a Braille & ASCII map renderer for your console. There’s a live version accessible via telnet on mapscii.me: $ telnet mapscii.me Panning and zooming using the mouse is supported. At the base is a vector tileset (from OpenMapTiles), with a Node app on top (written in CoffeeScript) sporting an ASCII …

The Mapbox Team: Recently, we’ve been thinking of a visualization that cuts directly to the way in which people make decisions about where to go: what would a map look like if we swept the physical world away completely, in favor of the time needed to move around it? We’ve been prototyping a simple discovery …
