GIS shapefiles for the June 27th lava flow at Kilauea volcano, Hawaii, June 2014-June 2016

This dataset contains shapefiles and associated metadata showing evolution of the "June 27th" lava flow (Pu?u ???? eruptive episode 61e) that was active at Kilauea volcano from June 27, 2014, to June 8, 2016. The dataset contains (1) an attributed polyline shapefile and (2) an attributed polygon shapefile with features that represent the outline and extent of the flow on 35 different dates. The dataset also contains (3) an attributed polyline shapefile with features that represent the eruptive fissures associated with this episode of the eruption and the principle ground cracks that were occupied by lava during lava flow emplacement, and (4) an attributed polyline shapefile with features representing the mapped extent of the active lava tube on six different dates. In total, this dataset contains four shapefiles, each with an associated metadata files in .txt and .xml formats. The geologic lines (lava flow contacts, the eruptive fissures, the ground cracks, and the lava tubes) were mapped on the ground or during helicopter reconnaissance flights using a handheld GPS, were digitized from satellite imagery or orthorectified aerial imagery (orthomosaics), were provided by the U.S. Geological Survey's Advanced Systems Center, or were (in a few instances) inferred. The relevant sources for each feature are assigned in the metadata attribute tables, but a lookup table for the data sources (DataSource.txt) is also included for convenience.
