suomi_fire

Rudimentary fire detection algorithm for the Suomi-NPP satellite

Usage

Within the project folder run: python3 main.py OBS_FP GEO_FP

• OBS_FP: Observation .nc file
• GEO_FP: Geolocation .nc file

Optional arguments: -c CFG_FP -o OUTPUT_F

• CFG_FP: Config .json file
• OUTPUT_FP: Output .json GeoJSON file

Configuration

Use config.json to select the frequency band, which quality flags to mask out, which processing steps to use (and in what order) and which parameters to use with these filters. You can also choose which of the filter steps to plot by setting their plot flag.

Output

Besides the plotted images, a GeoJSON file will be exported to the desired output path OUTPUT_FP including all detected fire regions as Polygon Features.

Possible next steps

• (Auto-)tune filter steps and settings
• Somehow differentiate night/day or ascending/descending captures
• Classify fires by size or intensity
• Improve Polygon creation to avoid "jagged" edges
• Add docstrings
