Wildfire Spread Dataset for Prediction Model

Wildfire Spread Prediction Dataset and Export Tool This repository contains a publicly available dataset and tools for wildfire spread prediction, focusing on incremental wildfire region segmentation using multi-source remote sensing data. The dataset and associated scripts are developed by researchers from Wuhan University, China, to support research in wildfire monitoring and prediction. Dataset Overview The dataset includes wildfire data from Canada and Alaska (2015–2019), integrating multi-source inputs for training and evaluating models like the RCDA-Net. It comprises: AffineParams: Contains affine transformation parameters for all 256×256 wildfire mask samples (2015–2019), stored in .pkl format (e.g., AffineParams/2015/UID_FIRE_2_transform.pkl). Each file is a tuple (x_origin, pixel_width, 0, y_origin, 0, pixel_height) in meters. SpatialRef: Includes a Test.shp file for retrieving the ESRI:102001 (North America Albers Equal Area Conic) coordinate reference system. test: Contains 1,630 samples with two subfolders: inputs: 12-channel input data (e.g., fire mask, DEM, BGR, NDVI, meteorological factors) as .npy files, each 256×256 pixels.The specific information of each channel is shown in the following table: Channel Data Type Spatial Resolution Temporal Resolution Source Input.1 Wildfire Mask Constant Daily ABoVE set Input.2 DEM 30m Constant ASTER GDEM V003 Input.3-5 Blue/Green/Red Bands 30m Constant Landsat 8/9 Input.6 NDVI 30m Constant Landsat 8/9 Input.7 Wind Speed 0.5°×0.625° Hourly MERRA-2 Input.8 Wind Direction 0.5°×0.625° Hourly MERRA-2 Input.9 Temperature 0.5°×0.625° Hourly MERRA-2 Input.10 Precipitation 0.5°×0.625° Hourly MERRA-2 Input.11 Humidity 0.5°×0.625° Hourly MERRA-2 Input.12 Air Density 0.5°×0.625° Hourly MERRA-2 Output.1 Wildfire Increment Mask Constant Daily ABoVE set labels: Single-channel incremental fire masks as .npy files, each 256×256 pixels. train: Contains 6,501 samples with two subfolders: inputs: 12-channel input data as .npy files, each 256×256 pixels. labels: Single-channel incremental fire masks as .npy files, each 256×256 pixels. Export Tool The Export2Tif.py script and its compiled executable Export2Tif.exe (generated via PyInstaller) enable users to convert .npy samples from the test or train datasets into GeoTIFF files with geographic information. The tool requires: Dependencies: Python 3.x with numpy, osgeo (GDAL/OGR), and pickle (included in standard library). For Export2Tif.exe, no Python installation is needed. Input File: ExportParams.txt with three lines: test or train: Specifies the dataset source. : The unique identifier of the sample (e.g., 8). : The fire occurrence date (e.g., 2018-06-06). Usage Prepare ExportParams.txt: Example content: test 8 2018-06-06 Place this file in the same directory as Export2Tif.py or Export2Tif.exe. Run the Script: Python Version: Execute python Export2Tif.py in a terminal with the required libraries installed. Executable Version: Double-click Export2Tif.exe or run it via command line. Output: GeoTIFF files are saved in the ExportResults/UID_FIRE_ _ folder, including 12 input channel files (Input.1.tif to Input.12.tif) and one output label file (Output.tif). Each file retains the ESRI:102001 projection and affine transformation from the corresponding .pkl file. Notes Ensure the AffineParams, SpatialRef, test, and train folders are in the working directory. The script pauses on errors (e.g., missing files) to allow debugging; press any key to continue. For large-scale batch processing, modify Export2Tif.py to loop through multiple ExportParams.txt files.
