Why use open source?

This Wiki will mainly focus on open source technology and open data. You might be asking yourself, "why open source?" There are various benefits to using open source, for example, freedom of choice, reliability, security and fast development. At the 2017 SDI-Open workshop, Eddie Pickle (DigitalGlobe Radiant, formerly Radiant Blue) presented on "How and why open source software has become mainstream for GIS". This presentation highlights the success of open source GIS.

With regards to web mapping libraries and tools, there are various options available. However, in my opinion, open source is by far the best option for creating web maps. The open source libraries and tools, such as GeoServer, PostGIS and OpenLayers, are widely used, and there are a huge amount of resources and examples available online.
