2019 Fire History Polygons at Yosemite National Park
van Wagtendonk K. 2020. 2019 Fire History Polygons at Yosemite National Park
This coverage represents the YOSE fire history from 1930 through 2018. Original data was interpreted from historical fire records held at Yosemite National Park in the late 1980s. GRASS data was converted to Arc/Info coverage format when Yosemite migrated to Arc/Info in 1995. Some vector data was lost in conversion from GRASS. In those instances, polygons were vectorized from raster versions that remained in GRASS. Each year from 1995 - 2000, fires were input into Arc/Info by digitizing 1:24,000 USGS paper maps (7.5" series) or from Trimble GPS readings. Starting 2001, all larger fire perimeters were acquired through ground GPS or helicopter GPS reconnaissance. Small fire point locations were acquired through ground GPS or helicopter GPS and buffered to approximate fire size
