Kullu Valley: The Beas Drainage System

The Kullu district expansion zooms out from the Parvati Valley to encompass the full Beas River drainage system — from Aut (1100 m) at the valley mouth to the Lahaul/Chenab divide (3080 m+) beyond Rohtang Pass. This is the geographic context within which the Parvati Valley sits. Geographic Extent Bounding box: 31.40–32.70°N, 76.80–78.00°E (~145 × 113 km) SRTM tiles: 4 (2×2 grid: N31E076, N31E077, N32E076, N32E077) Elevation range: ~800 m (Aut gorge) to 6632 m (Parbati Parbat) River System The Beas and its tributaries carve the district: ...

Mesh Generation: From Elevation to Geometry

A digital elevation model is a grid of numbers. A mesh is geometry that can be rotated, lit, textured, and explored. This stage transforms SRTM grids into OBJ meshes with UV-mapped satellite textures — ready for import into Blender or any 3D application. Mesh Products Name Extent Resolution Vertices Texture Peak Parbati Parbat ±10 km step=3 (~90 m) ~400K 2048² Sentinel-2 Valley Bhuntar to Pin Parvati step=4 (~120 m) ~300K 4096×2048 Sentinel-2 Expanded Full GHNP + Khirganga NP step=6 (~180 m) ~416K Bare (vertex colour) Kullu Full Beas drainage step=8 (~240 m) ~316K Bare (vertex colour) Output Format Each mesh produces three files: ...
