OPEN SOURCE SOFTWAREOpen-source software (OSS) is computer software with its source code made available and licensed with a license in which the copyright holder provides the rights to study, change and distribute the software to anyone and for any purpose.
Open-source software is very often developed in a public, collaborative manner.
A report by the Standish Group (from 2008) states that adoption of open-source software models has resulted in savings of about $60 billion per year to consumers.

Created to support and build the highest-quality open source geospatial software. Our goal is to encourage the use and collaborative development
of community-led projects
OSGeo also serves as an outreach and advocacy organization for the open source geospatial community, and provides a common forum and shared
infrastructure for improving cross-project collaboration.
