The recently published "Geospatial database of the 2018 lower East Rift Zone eruption of Kīlauea Volcano, Hawai‘i" contains data used to construct semi-daily lava-flow maps during the 2018 Kīlauea eruption.
The data were sourced from helicopter and Unoccupied Aircraft Systems (UAS) imagery collected by both the USGS and the University of Hawai‘i at Hilo, as well as from various satellite sources. This report supersedes the "preliminary" web map service that was operated in 2018, and which remains on ScienceBase as a legacy dataset (accessible here). The primary component of this new report is a geodatabase prepared using ArcGIS, but Esri shapefiles and Google Earth KMZs are also included.
