What I learned at State of The Map US

17 Apr 2014


This is part two of two of what I learned at SOTMUS. Part one can be found here

I want to add some more posts later diving deeper into some topics that interested me.

##Presentations Here are some random thoughts on some of the presentations. As with the previous post, I would encourage you to check out the linked videos and the presenters’ twitter accounts

####Open Data Alchemy - Chris Helm

  • before the presentation he was looking at FreshyMap
    • adding the wind.io functionality into any interactive map is pretty interesting
    • the dashboard of ski resort images is really slick
  • koop GeoJSON -> FeatureService is nice
  • koop GFS is badass
  • koop in general is really cool
  • ESRI maps will now be using OSM data.
    • Does licensing issues (share-alike) come into play here?
    • Is it really stupid that it even has to be asked? I think so, ESRI should be free to improve their maps with the best data around
  • koop API piping to geojson.io was really slick

####Drone Imagery for OpenStreetMap - Bobby Sudekum and Baptiste Tripard

  • you shake the senseFly drone three times to start it up…most likely i would have shaken the thing twice and dropped if from the cliff
    • there’s your ‘oh shit’ moment
  • speaking of ‘oh shit’ moments, I would be absolutely useless if I was up on the Matterhorn for that drone flight
    • actually more than useless, someone would have to carry me down the mountain
  • It crossed my mind a few times during the presentation as to how drone imagery could be used to map out response plans after tornadoes.
  • the 3D images of the matterhorn were absolutely stunning
  • sensefly you’re welcome

####Advanced CartoCSS Tricks - Kate Watkins, Seth Fitzsimmons and Alan McConchie

  • using modulo to randomize a slight pitch of the labels were pretty cool
  • I really dig the color scheme of the pinterest map
  • the nuggets of cartocss given (and explained) in the presentation was helpful
  • when designing your own map in tilemill2, just remember that it’s the ENTIRE map
  • really digging the patterns on backgrounds using the white and alpha quadrants

####Designing OpenStreetMap - Nicki Dlugash

  • function and context are ridiculously important to cartography
  • mapbox streets uses a subset of OSM data
  • it looks like mapbox is prepping a map solely for driving routes
  • the designs showed made me think about what is absolutely necessary on a weather map
    • need to get rid of or deemphasize the unnecessary basemap data, so the weather data will pop
  • mapbox outdoors was demoed…very cool…love the elevation lines
  • webgl rendering of vector tiles on the client was demoed at the end of the video…just ridiculous

####Processing OpenStreetMap Into Vector Tiles - Dane Springmeyer

  • my notes on this was probably 2-3 times longer than any other presentation.
  • the ravioli analogy makes a lot of sense.
  • the mapbox garage image is awesome.
  • the entire world on a USB stick. How f’n big is that USB stick??
  • working on FileGDB to vector tiles is awesome!
  • delta and zig zag encoding to make the file size smaller is just brilliant.
  • overzooming is great, but I wonder if there is a agreed upon zoom level to resolution ie 5km resolution data can stop at zoom level X
  • compositing on different overzoomed datasets is very interesting…makes a lot of sense
  • shapefile -> vector tile conversion 2000 tiles/second and dropping the dataset size down ~350MB WOW
  • OSM Bright Style open sourced…will definitely play with this.
  • another plug on Browser/WebGL rendering coming soon…I can’t wait to get my hands on that!
