FIRED Morocco Nov 2000 - July 2024

This is event-level polygons for the fire event delineation (FIRED) product for MOROCCO 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月摩洛哥地区火灾事件勾画（FIRED，Fire Events Delineation）产品的事件级矢量多边形数据。
该数据集源于MODIS MCD64A1燃烧面积产品（详细信息参见https://lpdaac.usgs.gov/products/mcd64a1v061/）。
MCD64A1是包含估算燃烧日期的月度栅格数据集。
Firedpy（https://github.com/earthlab/firedpy）是一款算法工具，可将上述栅格数据转换为事件级产品：先将完整时间序列堆叠为时空数据立方体，再通过算法为落入同一三维时空窗口的像元分配事件识别编号。
本次发布的数据集采用1个像元的空间参数与5天的时间参数生成。
本数据集包含每日多边形数据与事件级产品数据两类文件，二者采用统一的事件识别编号体系；但事件级产品为每个完整火灾事件仅生成单个多边形，而每日产品则为事件内每一日期分别生成独立多边形。

背景概述

该数据集是摩洛哥从2000年11月到2024年7月的火灾事件多边形数据，基于MODIS MCD64A1燃烧面积产品，使用firedpy算法将栅格转换为空间-时间事件，包括每日和事件级别的多边形。它提供了详细的火灾事件地理空间信息，适用于环境科学和遥感分析。
