43,000 km of 10cm imagery added for Denmark

By Chris Herwig on October 08 2014

We just added 43,000 km of brand new 10cm orthoimagery, covering all of Denmark, to Mapbox Satellite. We sourced the imagery from the Danish Geodata Agency and rolled out updates across the country of Denmark.

We just added 43,000 km2 of brand new 10cm orthoimagery to Mapbox Satellite. We sourced the imagery from the Danish Geodata Agency and rolled out updates across the country of Denmark. Part of the Danish government's eGovernment strategy 2011-2015, the imagery is released openly and accessibly via Denmark's basic data program.

Kastellet, in Copenhagen, is a classic star fortress, designed so that any attacker approaching one wall could be fired upon from at least one other wall. It included grassy areas in order to feed animals so it could last longer under siege. A Danish website remarks that: "The fact that some of the cannons actually point toward Copenhagen itself is due to King Christian III's concept of how to rule a country."

With this imagery's 10 centimeter-per-pixel resolution, we can do much more than count cars in parking lots:

Kultorvet Square, where the philosopher Søren Kierkegaard lived as a student, was recently redesigned by the local architecture/design firm Polyform.

Zoomed all the way in, we can see not just cars but bicycles, and which café tables are occupied.

In this image, we see rooftop solar installations, trampolines, and one fish pond that would be easy to confuse with a trampoline at a lower resolution. The number of trampolines amazed us when we started rendering the imagery. In some neighborhoods, we counted a 40% household trampoline ownership rate. Denmark is truly a kind of paradise.

Today's rollout includes the most recently captured aerial photography available, with more than half of the imagery captured within the past year.

The town of Svogerslev, a suburb of Roskilde. Wind turbines are scattered around the area. Denmark was an early adopter of wind power, which today supplies about 33% of grid power, and is on track to reach 50% by 2020. On stormy days over the last year, Denmark produced more electricity from wind than the entire country consumes and sold surplus energy to Germany and Norway.

Middelgrundsfortet is a sea fort between Copenhagen, the capital of Denmark, and Malmö, a Swedish city across the Øresund strait. The strait has been strategically vital from early Viking history to WWII, when Danish Jews were smuggled across it to Sweden. From 1429 to 1857, it cost money to pass through – the Sound Dues. Middelgrundsfortet was built in the 1890s as part of Copenhagen's defense perimeter, and was only retired late in the Cold War, by which time it was an antiaircraft installation. Valdi Private Islands lists it at a rumored price of about $20 million.

Amalienborg is the winter residence of the Danish royal family. It consists of four semi-separated rococo palaces facing a plaza featuring a huge statue of King Frederick V on a horse, visible here in shadow.
