My brain is overflowing at the end of the two days, and I have lots of things I want to look into more. This post is mainly a list of items I found interesting with some links. Apologies in advance to anyone / anything I missed out! Without further ado ...
CartoDBI continue to be very impressed with CartoDB. They first launched the product at FOSS4G in Denver in 2011, and released Version 2 in November 2012, with lots of cool new features. These include a new system called Torque which does beautiful spatio-temporal visualizations, and new density maps using either hexagons or squares. I definitely plan to work on including CartoDB in the solutions that we're offering. Check out Andrew Hill's presentation.
MapstractionAndrew Turner gave a lightning talk about Mapstraction, a library that provides an abstraction layer for the major mapping APIs. Last time I looked at this I had the impression it wasn't being very actively developed, but it seems I was misinformed! This is something I want to investigate further too. There's a nice sandbox demo site here.
Ubisense myWorldI did a short presentation and demo on what we're up to with Ubisense myWorld, building web applications for utilities and telecoms using Google Maps and various open source products. I'll do a longer post soon on what we've been up to recently, but we got some good interest in what we've done with Google Street View, including the overlay of linear objects like gas pipes, and also in work we did to help a customer with recovery efforts after Hurricane Sandy. Thanks to Steve Citron-Pousty for his summary:
WebGLBrendan Kenny from Google gave an interesting talk on WebGL, which brings high performance 3D (and 2D) graphics to (most) web browsers (no prizes for guessing which one is the main exception!). He did a really impressive demo that involved displaying very large numbers of points in the browser with dynamic charts based on the current map window and dynamic filtering tools.
Miscellaneous other linksIn no particular order ...
openweathermap.org is a cool resource for free and open weather data.
The Google Visualization API looks like a nice library for visualizing data tables and charts.
PhantomJS is a headless webkit browser that is useful for various things including browser screen capture and testing. This blog post talks about using it to implement a web map printing tool. Alfred Sawatzky talked about how he used this to capture periodic screen shots of his company iFactor's outage maps during the Hurricane Sandy recovery.
The ESRI CityEngine Web Viewer is a cool application for viewing 3D city models in a browser without any plugins. You can see various examples here, press the play button at the bottom left for an automated tour of a model. This one in Philadelphia is impressive.
Simtable are doing interesting things with projecting animated data onto 3D models.
MongoDB is a scalable open source NoSQL database that provides geospatial support - up until now just for points, but about to have support for any geoJSON geometry and operations like point in polygon etc. Steve Citron-Pousty ran a workshop on this which I would have liked to have gone to, but I went to the MapBox / CartoDB one instead.
So, lots of things to research and absorb!!
Update: Tyler Burgett also shared some excellent detailed notes, and Steve C-P has posted a good summary too.
