The use of Unique Identifiers (UUIDs) for managing spatial data has expanded in recent years, as have geospatial Digital Twins. This presentation explores the deployed use of SpaceTimeIDs, and opportunities and technical gaps for expanding into other spatial feature types.
The use of Unique Identifiers (UUIDs) for managing spatial data has expanded in recent years, as have the development of geospatially-focused Digital Twins. This presentation explores the use case of SpaceTimeIDs, as developed for the management of the Large-Scale International Boundaries (LSIB) dataset, and extrapolates on the opportunities and technical gaps of expanding the concept beyond boundaries into other spatial feature types. The utility of SpaceTimeID approach is twofold: first, the ability to maintain and track change over time, while simultaneously maintaining connection to a digital document store associated with the dataset; and second, the ability to manage datasets at an individual component and aggregate dynamically into higher order semantic concepts (think individual boundary segments defined in various treaties vs the entire boundary line shared between two countries). Any industry in which spatial data evolves over time, needs to maintain links to relevant documents through time, and that manages data at multiple semantic and conceptual tiers can leverage the SpaceTimeID model. Currently, SpaceTimeIDs are fully deployed in the management of the LSIB, fully integrated into the Boundaries and Sovereignty Encyclopedia (BASE) web application, and publicly released as part of the official dataset in the U.S. National Spatial Data Infrastructure. Additionally, SpaceTimeIDs are used in the production and encoding of the World Polygons dataset. The current workflows leverage a full open source software stack that extends through the spatial database, desktop GIS, data science, and web application tiers. Core elements of the SpaceTimeID framework are reviewed and technical gaps related to broader adoption discussed.
Dr. Joshua S. Campbell is the Founder of Sand Hill Geographic, a consultancy providing advisory services on geospatial technology, policy, and product management. Dr. Campbell has over 25 years of geographic information science and technology experience working across a range of national security, diplomacy, international development, and academic contexts. Most recently he served as the Senior Scientist in the Foundational GEOINT Office of the National Geospatial-Intelligence Agency's Research and Development Directorate. In this role he helped direct a research portfolio across a range of geospatial data and technology topics, including 3D production and analysis, advanced spatial data monitoring and modelling, and geophysics. Prior to NGA, he served as a Senior Advisor in the State Department’s Office of the Geographer and Global Issues. In this position he supported the Department’s Geographer, helping write the Department's first Geospatial Data Strategy, and managing several geospatial technology initiatives related to cartographic production, web-based GIS, and management of the official International Boundaries dataset. He is a Councilor of the American Geographical Society, voting member of the Humanitarian OpenStreetMap Team (HOT), and a charter member of the Open Source Geospatial Foundation (OSGeo). He holds a Doctor of Philosophy (Ph.D.) in Geography, Master of Arts in Geography, and Bachelors of General Studies in Anthropology, each from the University of Kansas.
