Alexandria - People and Water dataset

This dataset is a compilation of labeled data originating from Sentinel 1, Sentinel 2, and the Copernicus Digital Elevation Model (DEM). It offers a rich and comprehensive resource for those interested in geospatial analysis and remote sensing of the region incorporating Alexandria and several other notable locations in Egypt, Gaza, and Israel.

The dataset includes three distinct files and a directory, each containing specific data:

S1.tif: This file houses Sentinel 1 data specifically curated for Alexandria. The data is presented in two bands; Band 1 displays VV polarization while Band 2 displays VH polarization, both expressed in decibels (dB).

S2.tif: This file is contains Sentinel 2 data, again focusing on Alexandria. It comprises nine bands, namely B02, B03, B04, B05, B06, B07, B08, B11, and B12. It's noteworthy to mention that band B8A is not included in this collection.

DEM_Orientation.tif: This file contains the Copernicus DEM data for Alexandria. It incorporates four bands: Band 1 and 2 encode the aspect in sine and cosine respectively, Band 3 depicts the slope ranging from 0 to 1, and Band 4 represents height, which is normalized to the elevation of Mount Everest.

The accompanying directory is an exhaustive collection of 78 geospatial patches derived from various locations across Egypt, Gaza, and Israel. Each patch includes its own set of DEM_Orientation, S1, S2, and a unique label. These labels denote the amount of square meters of built-up area present in each 10x10m pixel, effectively representing built-up area coverage as a percentage. This crucial detail enables a deeper understanding of urbanization patterns and building densities across these regions.
