资源简介：
This is event-level polygons for the fire event delineation (FIRED) product for GUYANA from November 2000 to July 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7月圭亚那地区火灾事件轮廓（FIRED，Fire Events Delineation）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，详细信息可访问https://lpdaac.usgs.gov/products/mcd64a1v061/查询。MCD64A1是一款包含过火日期估算结果的月度栅格网格数据集。Firedpy（https://github.com/earthlab/firedpy）是一款算法工具，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火灾事件数据集，并通过算法为落入同一三维时空窗口内的像元分配事件识别编号。本次构建的特定数据集采用1像元的空间参数与5天的时间参数。本数据集包含逐日矢量多边形，两类文件（事件级产品与逐日产品）的事件识别编号保持一致，但事件级产品仅为每个完整火灾事件提供单个矢量多边形，而逐日产品则为对应事件的每个日期生成独立矢量多边形。有关方法细节与更多内容，请参阅以下学术论文：
