资源简介:
In this study, we used the monthly time series of medium spatial resolution remote sensing images (2003 to 2023) operated by the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor. All images were processed on the Google Earth Engine platform (https://code.earthengine.google.com). GEE is a scalable, cloud-based geospatial retrieval and processing platform that offers free in-cloud data access, processing, and administration. The MODIS product used for burned area assessment was from collection 6.1. The images of the burned area (MCD64A1) and active fire (MCD14DL and NRT) were computed from https://developers.google.com/earth-engine/datasets/catalog/MODIS_061_MCD64A1 and https://developers.google.com/earth-engine/datasets/catalog/FIRMS, In this study, over a 20-year study period (2003 to 2023), 252 images were processed at a rate of one image per month for the burned area through the GEE platform when setting up the code. Based on this information, a technique for processing, evaluating, and displaying geodata on forest fires and their consequences was created. The approach consists of four (4) main parts in this study, which are: acquiring and loading input data from publicly available geographic information web services (http://diva-gis.org/datadown)(Step1); pre-processing (filtering) of multi-channel satellite images, computation of indexed images (Step2); thresholding and saving the original data and outcomes in cloud storage (Step3) and then exportation in GIS for geoprocessing (Step3). At the end of the processing, the metadata is composed of data in shapefile format of the monthly and annual burnt areas over the period 2003-2023 as well as those of the active fires. All the data has been re-structured in an Excel file with the appropriate area and number of active points. Description of downloadable files: The single files for burned area mBA[year] contain the characteristics of the fire intensity and the occurrence. mBA[year]_Dissolve contain only one information about the area. The supplemental material contains the statistics of the burned area and active fire.
