Brick Kiln Dataset for Pakistan's IGP Region Using AI

This dataset represents the first geospatial mapping of brick kiln sites in the IGP region of Pakistan, providing an invaluable resource for understanding the spatial distribution of these sites. Each data point captures a brick kiln's precise location, including coordinates, state, and other important information, standardized in Coordinate Reference System (CRS) EPSG:4326 (WGS 84). This dataset, to the best of our knowledge, is the first of its kind to consolidate and geolocate brick kiln operations across this region, where air pollution impacts from kiln emissions are a significant environmental and public health concern.

In addition to the primary geolocation data, the dataset also includes an initial, secondary estimation of emissions (PM10, PM2.5, NOx, and SOx) from these sites. This supplementary information supports preliminary risk assessments, emphasizing proximity-based exposure for populations and sensitive areas (e.g., schools, hospitals) within a 1 km radius of each kiln site. 

The dataset is made available in multiple formats to facilitate wide usage across spatial analysis platforms:

• Geojson (.geojson)
• Shapefile (.shp)
• Comma-Separated Values (.csv)

Metadata:

• Geographic Coverage: IGP - Pakistan
• CRS: EPSG:4326 (WGS 84)
