Yesterday, Development Seed hosted an Open Mapping Happy Hour at our office in Blagden Alley. We were delighted that over 100 open mappers and FedGISers braved the rain for some great conversation and scheming.

A few highlights of last night’s presentations include:

• Dale Kunce announced the launch of the new Missing Maps website featuring user pages and leaderboards for tracking OpenStreetMap edits.
• Jubal Harpster showed off POSM (Portable Open Street Map), a field-deployable OpenMapKit server.
• Derek Lieu spoke about Macrocosm, an OpenStreetMap clone for a governments or large institution to collaboratively manage map data
• Mikel Maron spoke about Mapbox Open Source Initiatives.
• Becky Chen announced the launch of Astro Digital’s new Digital Imagery Browser. (As seen in TechCrunch!)
• Kiwako Sakamoto talked about India Lights a tool to explore 20 years of night time imagery over India
• Krystal Wilson noted The Tauri Group’s new Report on Space Startups

Thanks to everyone who came out last night. We had an awesome time hanging out and talking open mapping. Thanks also to Mapbox for cohosting the event.
