FIRED Bahrain Nov 2000 - July 2024

This is event-level polygons for the fire event delineation (FIRED) product for BAHRAIN 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:

本数据集为巴林（BAHRAIN）2000年11月至2024年7月期间的火灾事件划定（FIRED）产品的事件级多边形数据。

该数据集源自MODIS MCD64A1火烧区产品（详情参见https://lpdaac.usgs.gov/products/mcd64a1v061/）。MCD64A1是包含估算火烧日期的月度栅格网格（raster grid）。

Firedpy算法（https://github.com/earthlab/firedpy）通过将整个时间序列堆叠为时空数据立方体（spatial-temporal data cube），将这些栅格转换为事件；随后，该算法为属于同一三维时空窗口的像素分配事件识别编号。本数据集的生成采用了1像素的空间参数和5天的时间参数。

数据集中包含每日多边形，且两类文件的事件识别编号保持一致；但事件级产品中每个完整事件仅对应单个多边形，而每日产品中每个事件的每一天均对应独立的多边形。
