Website | @tmcw

Tom is a GIS developer at Development Seed, a strategic consultancy that specializes in building maps, data visualizations, and open source tools for international development agencies. He is a lead architect of Development Seed’s open source mapping stack that combines Mapnik, Cascadenik, OpenLayers, and some other open source tools for use online, and is the lead developer behind TileLive, a dynamic tile rendering toolset that provides fast, non-Flash interactive maps.

Tom works closely with the mapping team on the development of MapBox, a suite of open source tools that make beautiful custom maps and host them in the cloud, TileMill, an open source map editor that makes it easy to design and generate beautiful custom map tiles without GIS software expertise, and SlingshotSMS, a lightweight SMS gateway on a stick.

Tom is a frequent speaker on open source mapping technologies, having presented at International Conference on Crisis Mapping, GOSCON, and past Where 2.0 conferences, and he recently participated in the first ever code sprint for Mapnik.

In addition to mapping, Tom is an experienced open source developer with significant experience working in Javascript, Node.js, Drupal, Django, and Ruby. He received a bachelor’s degree in Computer Science from The College of William and Mary.

This presentation will demo TileLive and analyze its map rendering techniques, along with Google's and others, and show it in action in several use cases. Read more.
