" Who isn’t moved by images of the Earth at night?
In the contrast it shows between nature and settlement—in the civilizational network it reveals—it gestures at the mystery of human society. These composites are referenced in movies and in art and, especially, in data visualizations.
And I had assumed unthinkingly that the images above and below, last updated by NASA in 2012, were about as much as existed. A new database shows how much more there is. "
Volcanic islands can seem to appear out of nowhere, emerging from the ocean like breaching monsters of the deep. Below, Mika McKinnon explains how these odd geological formations are born, how they evolve, and how they eventually vanish back beneath the waves.
These high-quality images may look like photographs of world cities at night taken by astronauts from the International Space Station – but they are painstakingly constructed from public map data and finessed by artist Marc Khachfe
A sequence produced by data visualization experts 422 South. More dataviz here: 422.com/work/tag/data-visualisation.
Sequence was produced for NATS - the UK based global air traffic management company. NATS says: 'This data visualization was created from real flight data taken from a day in July 2013. It highlights the intensity of the operation in Europe - an operation which runs 24 x 7 x 365. NATS and the UK are at the heart of the operation. With Heathrow as the busiest international airport in Europe, and Gatwick as the busiest single runway airport in the world, we play a key role in ensuring air traffic under our control in European airspace is as safe and efficient as it can be.
" Asger S. Petersen (recipient of three LASmoons) Copenhagen, Denmark Partner & Consultant, Septima Background: The Danish Geodata Agency has acquired country wide LiDAR coverage. Approximately 1/4th of the country has been flown this spring and the GST has publishedpreliminary classified point cloud data. There are a lot of people in the Danish geodata community who are very excited to get to know this new data. "
" La géographie prioritaire de la politique de la ville est en voie de simplification. Grâce aux outils géomatiques, un seul critère va être pris en compte pour définir quelque 1 300 quartiers bénéficiant de mesures de soutien.
La définition finale ne sera effectuée qu’après une suite d’allers-retours avec les services déconcentrés (directions départementales de la cohésion sociale) et les collectivités concernées. Pour cela, une application a été développée exploitant l’API du Géoportail qui présente les anciens découpages ainsi que les propositions sur fond de BD Ortho et de cadastre. Les correspondants locaux, en concertation avec les élus, pourront ainsi proposer des modifications qui seront ensuite examinées à Paris avant d’être validées par les préfets. "
3D perspective maps have issues because they have convergent projection lines and fixed viewpoints. So why not make 3D maps with parallel projection lines and a viewpoint at infinity?
The Plan Oblique projection does just that. So does the Orthographic Oblique projection which is a derivative of the Plan Oblique. We generally prefer the Orthographic Oblique projection because the view appears more natural. Both have parallel projection lines, a viewpoint at infinity, and both are largely free of the issues associated with perspective 3D maps "
