FIRED Bolivia Nov 2000 - December 2024

This is event-level polygons for the fire event delineation (FIRED) product for BOLIVIA from November 2000 to December 2024. It is derived from the MODIS MCD64A1 burned area product (see https://lpdaac.usgs.gov/products/mcd64a1v061/ for more details). The MCD64A1 is a monthly raster grid of estimated burned dates. Firedpy (https://github.com/earthlab/firedpy) is an algorithm that converts these rasters into events by stacking the entire time series into a spatial-temporal data cube, then uses an algorithm to assign event identification numbers to pixels that fit into the same 3-dimensional spatial temporal window. This particular dataset was created using a spatial parameter of 1 pixels and 5 days. Daily polygons are included and the event identification numbers are the same for both files, but the event-level product has only single polygons for each entire event, while the daily product has separate polygons for each date per event. See the associated paper for more details on the methods and more:

本数据集为2000年11月至2024年12月期间玻利维亚的火灾事件勾勒（Fire Event Delineation，简称FIRED）产品的事件级矢量多边形数据。该数据集源自MODIS MCD64A1火烧面积产品，详细信息可参阅：https://lpdaac.usgs.gov/products/mcd64a1v061/。MCD64A1是一款包含火烧日期估算值的月度栅格数据集。Firedpy（https://github.com/earthlab/firedpy）是一款转换算法，其通过将完整时间序列堆叠为时空数据立方体，将上述栅格数据转换为事件级数据，并通过内置算法为落入同一三维时空窗口的像元分配事件标识号。本数据集采用的空间参数为1个像元、时间参数为5天。数据集包含逐日矢量多边形，且两类文件的事件标识号保持一致：其中事件级产品仅为每个完整火灾事件提供单个多边形，而逐日产品则为对应事件的每个观测日期生成独立多边形。有关该数据集与算法的更多细节可参阅以下学术论文：Balch, J.K.; St. Denis, L.A.; Mahood, A.L.; Mietkiewicz, N.P.; Williams, T.M.; McGlinchy, J.; Cook, M.C. 火灾事件勾勒（FIRED）：基于MODIS火烧面积产品构建的开放灵活算法与美国火灾事件数据库（2001–2019）.
