This document discusses the GI2015 forum focused on open geodata management for agriculture, forestry, and development across European regions. The forum aims to address challenges of cross-border connectivity and semantic interoperability of geospatial data and services. Specifically, it will focus on sustainability and interoperability of open data applications for public and private organizations. Previous events from 2000-2015 are discussed that helped establish the need for cross-border sharing of geospatial information.
