This document discusses opportunities for archaeology organizations to transition to open source digital tools for on-site data collection and archiving. It acknowledges challenges like resistance to change, differing expectations, and software dependencies. However, it argues that open source can work for professional geospatial applications and examines potential opportunities like better staff engagement, cost savings, and greater control over data. The conclusion is that organizations should examine their current workflows and software to evaluate the true costs of not investigating open source alternatives.
