Simuletic/Long_Distance_Wildfire_Smoke_Detection_Dataset

Long-Distance Wildfire & Smoke Detection Dataset (free sample)

A free sample of 239 synthetic images of distant wildfire smoke, seen from elevated fire-watch cameras, with YOLO bounding boxes for smoke and wildfire and a text caption per image, for training and testing wildfire and smoke detection models. Most images show smoke only, which is how an early wildfire usually looks from far away. Made by Simuletic, which builds synthetic CCTV datasets for computer vision.

What's in the images

Early wildfires seen from far away, the way a fire-watch camera on a tower or ridge sees them. Smoke usually shows long before flames, and flames are often hidden by terrain or trees, so most images show smoke only: a thin grey trail or a small plume rising from a ridge, valley or hillside. In 50 of the 239 images a small flame or orange glow is visible at the base of the smoke. Plumes are often tiny, low-contrast objects in a wide landscape.

Landscapes in the sample include forested valleys, rocky mountain ridges, dry Mediterranean pine forest, olive groves and scrub, limestone cliffs, dense conifer canopy, eucalyptus savanna and rural land with patches of woodland. The images come from 48 scene setups.

Classes and boxes

Class	YOLO id	What it marks	Boxes in sample
smoke	0	smoke plumes, wisps and columns	255
wildfire	1	visible flames	71

Smoke is boxed in 238 of the 239 images and flames in 47.

Each YOLO label line is class_id x_center y_center width height, normalised to 0–1. This smoke box (var1_early_wildfire_smoke_only_img1.txt) covers about 4% of the image width:

0 0.492574 0.364480 0.039604 0.068069

wildfire_detection_dataset.jsonl has one line per image in chat format: a fixed question, and an answer with the alert status (smoke only, or flame visible), the location and what is seen. Use it to fine-tune vision-language models that write alert messages:

{"image": "var1_early_wildfire_smoke_only_img1.png", "conversations": [{"role": "user", "content": "Analyze this long-range optical sensor feed for early signs of wildfire."}, {"role": "assistant", "content": "Alert Status: Early Wildfire Smoke Only. Location: a deep forested valley under a clear blue sky. Observation: a subtle trail of grey smoke drifting up from a remote rocky ridge. Only smoke visible."}]}

Quick start (Ultralytics YOLO)

Create a data.yaml next to the dataset folder (quote the path, it contains spaces):

path: "Long-Distance  Wildfire & Smoke Dataset"
train: images
val: images   # small sample: use the same images, or split them yourself
names:
  0: smoke
  1: wildfire

Then train:

from ultralytics import YOLO

model = YOLO("yolo11n.pt")
model.train(data="data.yaml", epochs=30, imgsz=640)

Use cases

• Wildfire early-warning camera networks and AI-assisted lookout towers
• Forest and national park monitoring
• Monitoring utility lines and the edge between towns and wildland
• Vision-language models that describe smoke and fire in an alert, using the captions
• Benchmarking detectors on small, distant, low-contrast objects

How the images were made

The images are fully synthetic (computer-generated) by Simuletic: no real people, places or incidents are depicted, so there are no privacy or consent issues.

Limitations. Synthetic images do not cover every camera, lens, compression artefact or scene you will meet in deployment. Validate on your own footage, and for production combine synthetic and real data. This sample has 239 images from 48 scene setups; the full dataset has 1,500 images across more biomes, times of day and weather.

Full dataset and custom data

The full Long-Distance Wildfire & Smoke Detection Dataset has 1,500 images, YOLO, classes smoke, wildfire. Licence: research $149 / commercial $590 per 1,000 images. Larger sets, other scenes, camera angles or classes: see custom data or write to contact@simuletic.com.
