Loose agenda:

I am obsessed with maps and have always been enamored with the USGS topos due to their high level of detail, but got frustrated that they were so out-of-date and neglected. I also grew tired of seeing most other map providers constantly regurgitating the same old USGS rasters and calling them “new” or “unique” which is what inspired me to start the amTopo line of truly original 7.5 Minute topos I started using MapServer in 2011 when amTopo was launched, and it has been amazing. My developer wrote custom code (I think in C++) that fetches base DEM data and processes it for generation of contours and hillshading, and the same code also creates the navigational collars and legend info that appears on each map.

  • The team from @broadstreetmaps will talk about their start-up company, which makes maps for public health organizations and social enterprises working in development. They’ll be introducing their visualization work, and seeking feedback on products, tools, and strategy!

  • @svmatthews has been jammin with @lyzidiamond on a new project about mapper groups and meetups. He wants to make the project more collaborative and start pushing in more functionality by getting the good people at CUGOS to fork and help out.

  • @jradavenport from UW who has created 24hrs of King County Metro will talk about how he created this data visualization video to display metro bus movement.

  • @dshean will share some large prints (and likely some slides) of annual 2 m/px WorldView Stereo DEM mosaics for West Antarctica’s “weak underbelly” - an area roughly the size of New Mexico.

  • @foundatron To stream/record CUGOS meetings on Google+ Plus Hangouts…or not? Discuss.


Lots of new faces. 50+ (53 to be exact) at the meeting.

Room full of people
