+# ArcticDEM 32 m Mosaic
+
+## Dataset Summary
+A publicly-accessible digital elevation mosaic covering the Arctic region, derived from the Polar Geospatial Center’s ArcticDEM project, at 32 m horizontal resolution.
+
+---
+
+## 📘 Dataset Description
+
+- **Source**  
+  Provided by the University of Minnesota’s Polar Geospatial Center (PGC), part of the ArcticDEM initiative funded by NSF & NGA ([website](https://www.pgc.umn.edu/data/arcticdem/)).
+
+- **Spatial Coverage**  
+  Pan-Arctic: regions north of ~60° N (Greenland, Canada, Russia, Alaska, etc.).
+
+- **Resolution**  
+  Mosaic tiles at 32 m pixel spacing derived from 2 m strip data.
+
+- **Temporal Context**  
+  Mosaics built from multi-date strip DEMs, assembled via median-stacking; the 32 m product is a static mosaic without temporal layers.
+
+- **File Format & Projection**  
+  - Format: 32-bit GeoTIFFs  
+  - Projection: NSIDC Polar Stereographic North (EPSG:3413)  
+  - Vertical datum: WGS84 ellipsoid
+
+- **Data and Quality Bands**  
+  - Elevation band  
+  - Optional quality masks (source count, med-abs-dev)  
+  - Voids flagged with NoData (–9999)
+---
+
+## 🔧 Supported Tasks
+
+- Regional elevation modeling  
+- Terrain analysis (gradient, aspect, watershed)  
+- Large-scale environmental and geospatial modeling  
+- Baseline surface for Arctic research & visualization
