Qattara Depression and surroundings: reproducible 2D and 3D maps of published groundwater evidence

Interactive Arabic-language 2D (v0.1.2) and 3D (v0.2.4) maps of published groundwater evidence for the Qattara Depression and surroundings, Egypt. The compilation contains 200 study records from eight studies, including 198 within the display extent, and seven 3D scenes. It preserves reported units, source attribution and uncertainty notes. The archive includes offline HTML viewers, evidence data, PNG/PDF exports, the source SRTMGL1 DEM (EGM96), build/test scripts and SHA-256 manifests. It accompanies Elsayad & Elsayad (2026), Results in Engineering, 32, 113445 (https://doi.org/10.1016/j.rineng.2026.113445), and the related Arabic manuscript.
