The Loc-I project aims to improve data integration and decision making capability across multiple geographies published by Australian government agencies. In Loc-I, each geography and its features are identified precisely, unambiguously, with rich descriptions and semantics, via Linked Data URIs, and is made available via multiple views that are both human- and machine-readable, and in multiple formats. Loc-I aggregates the geographies in scope into a Hybrid Spatial Knowledge Graph and provides APIs for queries. The Hybrid Spatial Knowledge Graph provides a reference graph cache for querying and traversing features. To date, we have integrated the following geographies: Aus. Bureau of Statistics’s Australian Standard Geography Standard; Aus. Bureau of Meteorology’s Geofabric; PSMA G-NAF Address dataset. We discuss easy vs. challenging aspects of spinning up the Loc-I spatial knowledge graph.

This presentation was given at the Earth Science Information Partners (ESIP) Winter Meeting held in Bethesda, MD in January 2020.
