##An Open Mapping Tool Chain
The process of adding data to OpenStreetMap to styling and publishing your maps online is not obvious at first. I'll walk though the open source tool chain we use to contribute to OSM, and how to use TileMill to leverage OSM data to build custom maps. Specifically I will share some of our recent experience over the past several weeks of tracing in Brazil and publishing maps online. I will share specifics on how to get started tracing roads and buildings from satellite imagery in a few minutes to how we actively engage local communities and working with local governments to open large datasets and import them to OpenStreetMap. Finally I will end showing how how to turn an OSM export into a map and publish it on your web site.
This looks good. Changed the first sentence some. If you like, I can submit.
Open Mapping: From Tracing in OpenStreetMap to Mapping in TileMill
Many are calling this the "year of the open map" because of the surge in open data and open data communities like OpenStreetMap and the new availability of open source tools like TileMill and MapBox that make it easier to work with and map this data. For the past several weeks we have been working strategically with the OpenStreetMap community to improve coverage in some of the most poorly mapped areas of the world. While a large part of this has involved tracing roads and buildings from satellite imagery, we are also actively engaging local communities and working with local governments to open large datasets and import them to OpenStreetMap. I'll talk about the tools we use to contribute to OSM and how to use TileMill to style your data once it's in OpenStreetMap.
