If you were to look under the hood of GeoExpress 7 – and the rest of our products – you’d find that LizardTech, like a lot of other companies in our industry, relies on open source software. In our case, we’re experts in compression and wavelets and geospatial imaging, and so we spend a lot of our R&D dollars in those areas. But for the stuff we’re not experts in – like reading the GeoTIFF format, parsing XML, and handling projection systems – we find better value relying on open source solutions.

As someone once said, though, “the gift economy ain’t free”: there’s a moral imperative to give something back.

Since Michael P. Gerlek has already blogged about the second birthday of the Open Source Geospatial Foundation (OSGeo), I thought I’d mention that in addition to his day job running part of our engineering team, Michael helps support the open source community by serving as editor for the monthly “Open Sources” column in GeoConnexion magazine.

Under the auspices of OSGeo, he has worked with many of the leaders of the open source geo world to shepherd nine 1000-word articles into print so far, with several more queued up for future issues.
