City Street Orientations around the World - Geoff Boeing
▻http://geoffboeing.com/2018/07/city-street-orientations-world

By popular request, this is a quick follow-up to this post comparing the orientation of streets in 25 US cities using Python and OSMnx. Here are 25 more cities around the world:

qui fait suite aux villes américaines: Comparing City Street Orientations
▻http://geoffboeing.com/2018/07/comparing-city-street-orientations

Each of the cities above is represented by a polar histogram (aka rose diagram) depicting how its streets orient. Each bar’s direction represents the compass bearings of the streets (in that histogram bin) and its length represents the relative frequency of streets with those bearings.

Un petit topo sur la vie grouillante des sols. Bonne visite !

Petite visite en terre inconnue, dans ce repaire où, bien à l’abri des regards, un microcosme souterrain s’active à l’accomplissement du grand œuvre : fabriquer du sol et faire pousser des plantes... éternellement.

#OpenRouteService #API : A #Leaflet example for #Isochrones

The page OpenRouteService.org is a very easy to use website which provides routing from A to B via C. It also allows to choose between different routing types for trucks, pedestrians or bicycles and isochrone analyses based on time and distance. In this article I would like to show you, how to embed the OpenRouteSevrice API into your very own Leaflet based webmap.

#map

reducing label clutter across mapping libraries

Labelgun is a mapping library agnostic labelling engine. It allows you to avoid cluttering in mapping popups and labels, providing precedence to labels of your choice.

The library makes three assumptions:

– Each label has a bounding rectangle (Min X, Min Y, Max X, Max Y)
– Each label has a weight
– You can provide a function that will hide and show a label (e.g. through CSS class or JavaScript function)

Announcing #Leaflet 1.1.0

▻http://leafletjs.com/2017/06/27/leaflet-1.1.0.html

We have released Leaflet version 1.1.0, the first version built with ES6 modules - a big step forward ensuring Leaflet is up to date with how modern JavaScript is written. For users upgrading to this release, this change should not make a difference, while it offers the possibility to import individual parts of Leaflet individually if your app is built with ES6. As a consequence, 1.1.0 is also the first version built without Leaflet’s now deprecated custom build system, in favor of using Rollup.

Also new in this release is the new L.VideoOverlay class, allowing overlaying video on your #maps.

▻http://leafletjs.com/examples/video-overlay

We also managed to fix over 30 bugs with the help of about 20 different contributors: see the full changelog for details.

Meet Leaflet 1.0. - Leaflet - a JavaScript library for interactive maps
▻http://leafletjs.com/2016/09/27/leaflet-1.0-final.html

Today marks the final release of #Leaflet 1.0. It’s a culmination of several years of work by dozens of contributors from all over the world. This is the fastest, most stable and polished Leaflet release ever.

The changelog contains over 400 changes compared to the previous stable, v0.7.7. The highlights include:

– Huge performance improvements in all aspects of the library and vector layers in particular.
– New L.Tooltip class for all your dynamic labeling needs.
– Flyover animations (zooming and panning in a curve with map.flyTo).
– Fractional zoom level support (map.setZoom(12.34)).
– Much better tile loading algorithm with less flickering.
– Custom pane management (including multiple vector layer panes and interleaving vectors and tile layers).
– Better support for non-standard projections.
– More accessibility features.
– Vastly improved documentation.
– Tons of bugfixes and stability improvements.

...

Starting with 1.0, we’re switching to a fast release cycle, where a new version will come out every 2–4 weeks. We’ll also prefer many small, incremental changes (with releases in between) over ambitious rewriting quests.

3 mai 2016. La plus grande catastrophe du #Canada s’abat sur Fort McMurray, le trésor de guerre du pays, troisième réserve mondiale de #pétrole. Les pompiers vont l’appeler « la Bête. » Il était temps de revenir dans cette ville où j’avais passé trois hivers.
