[Flowdata] flux affecté sur réseaux (route et rail) temporels suisse | Opendataswiss

*Pépite, suffisamment rare pour pouvoir être mentionné.

La Suisse propose sur son #opendata @opendataswiss plusieurs jeux de données géographiques décrivant les valeurs de charge (trafic journalier moyen) pour les voyageurs (transports publics et transport individuel motorisé) et les marchandises sur réseaux routiers et ferroviaires, le tout à différentes dates : 2010, 2011, 2012, 2015, 2020, 2030 et 2040.

C’est juste extra ordinaire !

#mapshaper
▻https://github.com/mbloch/mapshaper

Mapshaper is a program for editing polygon and polyline datasets for mapping. The command line interface has commands for line simplification, polygon aggregation, attribute field calculation, filtering, splitting, table joins and more. The web-based gui focuses on interactive simplification.

Mapshaper can read and write #Shapefile, #GeoJSON and #TopoJSON files.

(...) examples:

Extract the border between two states. mapshaper --filter "STATE=='OR' || STATE=='WA'" --innerlines states.shp

Generate two new fields using JavaScript. mapshaper --expression "STATE_FIPS=CNTY_FIPS.substr(0, 5), AREA=$.area" counties.shp

So for starters I thought a simple kernel density estimate of shelters might be something to do. The plan was to get the OSM data using the R package osmar, then create a 2d smoothing, then write that as a raster and map it in QGIS

Adventures in Mapmaking : How to Map the Age of Buildings in Your Hometown - Wired Science
▻http://www.wired.com/wiredscience/2013/10/how-to-map-building-ages-in-your-home-town

You may have seen some of the beautiful maps of building ages that have been cropping up around the internet. I first noticed an amazing one of Portland, and then another great one of Brooklyn. I decided I wanted to try to make one of San Francisco, but, as I still know very little about making maps, I knew I’d need help.

So I called up Thomas Rhiel of the independent journalism site BKLYNR.com. Rhiel was willing to help, and it turns out he was just the right person to advise me. His map of Brooklyn building ages was his first foray into mapmaking, so he had just muddled his way down the same path I was about to navigate.

I’m going to tell you exactly how I made this map. I hope that people with little or no experience making maps will be able to use this as a guide to getting started on a map of their own hometown. And I also hope expert mapmakers will chime in to tell us how we can improve our maps.

►https://github.com/straup/Clustr#readme

Clustr takes a text file containing longitude/latitude points, tagged with a bit of text, and attempts to generate minimal polygons that “cover” those points, using an “alpha” parameter to determine the notion of “coverage”. The polygons are written to an ESRI Shapefile, suitable for use in GIS software.
