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.
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!
