Fantasy map generator

This is fun. It’s a fantasy map generator with the following rules: Project goal is a procedurally generated map for my Medieval Dynasty simulator. Map should be interactive, scalable, fast and plausible. There should be enought space to place at least 500 manors within 7 regions. The imagined area is about 200.000 km2. Just click and there’s a new map generated on the fly. Martin O’Leary’s generator is still my...

Redistricting the congressional map with different goals

FiveThirtyEight asks, “There’s a lot of complaining about gerrymandering, but what should districts look like?” Looking for an answer, they imagined redistricting with different goals in mind, such as gerrymandering favoring Republicans or Democrats, promoting competitive elections, and maximizing majority-minority. Check out the possibilities for the nation or zoom in to a specific state. The latter provides a further breakdown by district and then race. So yeah, if you’re into...

Mapping global accessibility to cities

From The Malaria Atlas Project, a global map of estimated accessibility to cities: In the present study, we quantify and validate global accessibility to high-density urban centres at a resolution of 1×1 kilometre for 2015, as measured by travel time. The last global mapping effort to measure accessibility was for the year 2000, a time that predates both substantial investment and expansion of transportation infrastructure and an extraordinary improvement in...

Scale comparison of wildfires

The past few days in California has been non-stop rain, but the months before that, there was unprecedented wildfires in the state. Lauren Tierney, reporting for The Washington Post, provides an overview along with a scale comparison of 2017’s biggest fire against anywhere on the globe.

Mapping perceived canopy tree cover in major cities

Treepedia, from the MIT Senseable City Lab, estimates perceived tree cover at the street level. They used panorama views from Google Street View to form a “Green View Index”, which they then mapped for major cities. Treepedia measures the canopy cover in cities. Rather than count the individual number of trees, we’ve developed a scaleable and universally applicable method by analyzing the amount of green perceived while walking down the...

Family displacements through urban renewal

Hundreds of thousands of families were displaced in the 1950s under “urban renewal” programs. The families were disproportionately minorities. Renewing Inequality, from a research group at the University of Richmond’s Digital Scholarship Lab, revisits the topic and how it reflects in the present. Renewing Inequality presents a newly comprehensive vantage point on mid-twentieth-century America: the expanding role of the federal government in the public and private redevelopment of cities and...

Simulation shows swirling of smoke, sea salt, and dust around the world

NASA. Data. Good. Tracking the aerosols carried on the winds let scientists see the currents in our atmosphere. This visualization follows sea salt, dust, and smoke from July 31 to November 1, 2017, to reveal how these particles are transported across the map. The first thing that is noticeable is how far the particles can travel. Smoke from fires in the Pacific Northwest gets caught in a weather pattern and...

Bomb contaminants where you live

Lena Groeger, Ryann Grochowski Jones and Abrahm Lustgarten, reporting for ProPublica with a searchable map of sites in need of bomb cleanup: The military spends more than a billion dollars a year to clean up sites its operations have contaminated with toxic waste and explosives. These sites exist in every state in the country. Some are located near schools, residential neighborhoods, rivers and lakes. A full map of these sites...

High-detail landscape using lidar data

Lidar, which is like radar but with lasers instead of radio waves, can provide high-detail surveys of the land. The state of Washington is using the tool for beautiful results. In 2015, the Washington State Legislature mandated that the Department of Natural Resources, Washington Geological Survey collect, analyze, and publicly distribute detailed information about our state’s geology using the best available technology – lidar. The main focus of this new...
