This document explains how to use the Wildfire Delineation pretrained model available on ArcGIS Living Atlas of the World. This deep learning model is used to generate a classified raster from Sentinel L2A imagery.
Wildfires, also referred to as forest fires or bushfires, are uncontrolled blazes that takes place in wilderness or rural areas. They indirectly signal the state of ecological balance and can be extremely destructive, posing threats to wildlife, natural resources, residential areas, and human lives. Early detection and monitoring of wildfires facilitate an effective response. Delineating wildfires assists in risk assessment, evacuation planning, damage assessment, ecological impact analysis, and the allocation of resources. Additionally, this model can be used to segment the lava flow of volcanoes.
License requirements
To complete this workflow, the following are the license requirements:
- ArcGIS Desktop—ArcGIS Image Analyst extension for ArcGIS Pro
- ArcGIS Enterprise—ArcGIS Image Server
- ArcGIS Online—ArcGIS Image for ArcGIS Online
Model overview
This model has the following characteristics:
- Input—Sentinel-2 L2A 12-bands multispectral imagery using Bottom-Of-Atmosphere (BOA) reflectance product.
- Output—A classified raster with the class as fire.
- Compute—This workflow is compute intensive, and a GPU with minimum CUDA compute capability of 6.0 is recommended.
- Applicable geographies—The model is expected to work well globally.
- Architecture—The model is implemented using computer vision techniques.
- Accuracy metrics—This model is implemented using computer vision techniques, and due to unavailability of ground truth data, accuracy metrics are not available.
- Limitations—This model exhibits limited effectiveness in delineation of fire within urban environments. The presence of bright regions or pixels, or the detection of a single pixel, may lead to instances of false detection. Thus it is recommended that you use it mainly in wild forest areas, with a threshold setting of 0.3 to 0.5, and with cluster detections.
Access and download the model
Download the Wildfire Delineation pretrained model from ArcGIS Living Atlas of the World. Alternatively, access the model directly from ArcGIS Pro using the Detect Objects Using Deep Learning tool, or consume it in ArcGIS Image for ArcGIS Online.
- Browse to ArcGIS Living Atlas of the World.
- Sign in with your ArcGIS Online credentials.
- Search for Wildfire Delineation and open the item page from the search results.
- Click the Download button to download the model.
You can use the downloaded .dlpk file directly in ArcGIS Pro, or upload and use it in ArcGIS Enterprise. Additionally, you can fine-tune the pretrained model if necessary.
