Not very often do I see open source mentioned on the front page of my Google Finance page (let alone Geospatial Open Source). But here it is.. the announcement was made at FOSS4G2007 that autodesk will be open sourcing part of it's coordinate system and map projection technology.
So what motivation does Autodesk (or any other company) have to open source it's technology? An important line from Lisa Campbell, vice president, Autodesk Geospatial:
"Our intent to contribute again to the open source community is a reflection of our customers' desire for faster innovation, more frequent product releases, and lower total cost of ownership."
