Full historical database on fire occurrences in the natural core of Falz-Fein Biosphere Reserve "Askania Nova", Ukraine during 1974-2024. Georeferenced vector polygons with statistics

A retrospective analysis of fires and identification of burned areas in the natural core of the Askania Nova Biosphere Reserve (Kherson region, Ukraine) was carried out using archival images from Landsat-1, 2, 5, 7 satellites (1974–2015) and the Sentinel-2 satellite constellation (2015–November 2024). The obtained materials are consistent with the data of long-term ground field surveys of the steppe. The current dataset is organized as a multipolygon GEOJSON file with a coordinate reference system WGS 84 / UTM zone 36N, EPSG:32636. Each polygon represents single burned area with information on it (year, date, area, reference information, fire cause, block squares covered) Interactive maps are available at https://spatiolab.com/en/examples/project?id=156&cid=29本研究依托1974—2015年陆地卫星（Landsat）1、2、5、7号存档影像，以及2015年至2024年11月的哨兵2号（Sentinel-2）卫星星座存档影像，对乌克兰赫尔松地区阿斯卡尼亚-诺瓦生物圈保护区（Askania Nova Biosphere Reserve）自然核心区的火灾开展回溯性分析，并完成过火区域识别。所得研究数据与该草原长期野外实地勘测数据保持一致。 本数据集采用多面GeoJSON（multipolygon GEOJSON）格式进行组织，坐标参考系统为WGS 84 / UTM 第36北带（EPSG:32636）。每个多边形对应一处独立过火区域，并附带其年份、日期、面积、参考资料、起火原因、覆盖地块网格等相关信息。 可通过以下链接获取交互式地图：https://spatiolab.com/en/examples/project?id=156&cid=29
