My contribution to AWF-Wiki
I initiated the AWF-Wiki project in 2009. Basis for the idea to create a Wiki on Forest Inventory and Remote Sensing came up during my working experience in an IT enterprise, where a Wiki platform was used for the documentation of software products and to share knowledge on software development with the customers. Having this idea in mind i was quite confident that a Wiki might serve as additional resource and knowledge reference for students and might also attract other scientists. Unfortunately Wikipedia, the the most famous Mediawiki installation, is only of limited use in this context, as students need in depth explenations and examples what doesn't really fit into the conventions for articles in Wikipedia. Therefore i decided to create a special Wiki for our purpose. The initial content in this Wiki is limited to some lecture notes so far, but we have good hope that our resources will become relevant and helpful for our students in future. I like to see it as a start for sustainable capacity building and hope we find the resources to extend and enhance this offer over the next years.
I am highly grateful to the MediaWiki contributors!
