Codes
//Step 1 *****************************************************************
// Load the SRTM DEM dataset
var srtm = ee.Image("USGS/SRTMGL1_003");
//Step 2 *****************************************************************
// Load the Chamoli district boundary from your assets
var roi = ee.FeatureCollection('users/ursgisag159/Chamoli_District_Shp');
// Center the map on Chamoli
Map.centerObject(roi, 9);
// Clip the SRTM DEM to the Chamoli district boundary
var srtmChamoli = srtm.clip(roi);
// Add Chamoli district boundary to the map
Map.addLayer(roi, {color: 'red'}, 'Chamoli District');
//Step 3 *****************************************************************
// Define visualization parameters for SRTM DEM
var visParams = {
min: 800,
max: 7000,
palette: ['0000FF', '00FFFF', '00FF00', 'FFFF00', 'FF0000', 'FFFFFF']
};
// Add the SRTM DEM layer to the map
Map.addLayer(srtmChamoli, visParams, 'SRTM DEM over Chamoli');
// //Step 4 *****************************************************************
// Export the image to Google Drive
Export.image.toDrive({
image: srtmChamoli,
description: 'SRTM_DEM_Chamoli',
folder: 'EarthEngineExports', // Google Drive folder (optional)
fileNamePrefix: 'srtm_dem_Chamoli', // File name prefix
region: roi, // The region to export
scale: 30, // Export resolution (SRTM is 30 meters)
maxPixels: 1e9, // Maximum allowed pixels for export
});
// Export the image to Earth Engine Asset
Export.image.toAsset({
image: srtmChamoli,
description: 'SRTM_DEM_Asset',
assetId: 'users/ursgisag159/SRTM_DEM_Chamoli',
region: roi,
scale: 30,
maxPixels: 1e9
});
// Export the image to Google Cloud Storage
Export.image.toCloudStorage({
image: srtmChamoli,
description: 'SRTM_DEM_GCS',
bucket: 'your-bucket-name', // Change to your Google Cloud Storage bucket
region: roi,
scale: 30,
maxPixels: 1e9
});
