Sentinel-2 Dataset – New Delhi Region

Dataset Description

This dataset comprises multispectral satellite imagery acquired by the mission over the metropolitan region. Sentinel-2 is part of the Copernicus Programme of the European Space Agency (ESA) and is designed for high-resolution monitoring of land surfaces, urban areas, and environmental processes.

The dataset is intended for geospatial analysis tasks such as image segmentation, feature extraction, and bi-temporal change detection in dense urban and peri-urban environments.

Spatial Coverage

The dataset covers New Delhi and its surrounding areas, capturing a diverse range of land-cover types including dense built-up regions, transportation networks, vegetation, water bodies, and agricultural land. This spatial diversity makes the dataset suitable for urban mapping and environmental monitoring applications.

Spectral Characteristics

Sentinel-2 provides imagery across 13 spectral bands in the visible (VIS), near-infrared (NIR), and shortwave infrared (SWIR) regions. The bands are available at spatial resolutions of 10 m, 20 m, and 60 m, allowing both fine-scale urban analysis and broader environmental assessments.

Key spectral capabilities include:

  • High-resolution visible and NIR bands for urban and vegetation analysis
  • SWIR bands for moisture, soil, and built-up area characterization
  • Atmospheric bands supporting radiometric correction

Temporal Resolution

The dataset benefits from Sentinel-2’s high revisit frequency of approximately 5 days using the combined Sentinel-2A and Sentinel-2B satellites. This enables bi-temporal and multi-temporal analysis for monitoring urban expansion, seasonal vegetation changes, and environmental dynamics.

Data Products

The imagery is typically provided as:

  • Level-1C: Top-of-Atmosphere (TOA) reflectance
  • Level-2A: Bottom-of-Atmosphere (BOA) surface reflectance

Data are distributed in a tiled format using the UTM/WGS-84 coordinate reference system and are compatible with common geospatial and remote sensing software tools.

Intended Use

This dataset is suitable for:

  • Image segmentation of urban and natural features
  • Feature extraction for geospatial machine learning models
  • Land-use and land-cover (LULC) classification
  • Bi-temporal change detection
  • Urban growth and environmental monitoring
