Ukraine Fire Perimeters 2022

The data set contains the fire perimeters for Ukraine for 2022 sourced from remote sensing data. The locations and dates of burning were detected using MODIS/VIIRS products on thermal anomalies. This information was used to select pre- and post-fire Copernicus Sentinel 2 L2A imagery. Satellite images were screened from clouds, cloud shadows and combined into median composite mosaics. The image mosaics were created using all available imagery within a 14-day time window before (pre-fire mosaic) and after (post-fire mosaic) each fire. Fire perimeters were visually delineated by comparing post and pre-fire image mosaics using a SWIR2–NIR–Red band combination. The spatial accuracy of fire perimeters corresponds to Sentinel 2 data at 20-m spatial resolution.

Delineated fire perimeters were intersected with the Copernicus Dynamic Land Cover map at 100 m resolution (v.3.0.1) to extract burned areas of five land cover classes according to the following reclassification scheme of the original pixel values.

MetaData

Field name

Description

id
Unique identifier of each fire perimeter

longitude
Longitude referring to centroids of fire perimeters

latitude
Latitude referring to centroids of fire perimeters

date
Date of burning in the format DD.MM.YYYY

year
Year

month
Month

day
Day of the month

week
Week number in the year

reg
The capital city name of the Ukrainian regions (oblast) associated with each fire

occupied
A binary indicator variable referring to the locations of each fire within the Russian-occupied territory (1) or within the territory controlled by the Government of Ukraine (0) for a given date

buff_30km
A binary indicator variable referring to the location of each fire within a 30-km buffer zone on both sides of the front line. In contrast to a daily progression front line used to detect "occupied" territory, the buffer was calculated using the farthest position of a frontline towards territories controlled by the Government of Ukraine

emerald
A binary indicator variable referring to locations of each fire within the Emerald network

 Burned areas by land cover (LC) type (in hectares) within the fire perimeter according to the Copernicus Dynamic Land Cover map at 100 m resolution (v.3.0.1)

LC_0
N/A

LC_1
Coniferous forest

LC_2
Broadleaved forest 

LC_3
Other natural landscape

LC_4
Agricultural land 

LC_5
Settlement
