Export.image.toDrive

Creates a batch task to export an Image as a raster to Drive. Tasks can be started from the Tasks tab. "crsTransform", "scale", and "dimensions" are mutually exclusive.
UsageReturns
Export.image.toDrive(image, description, folder, fileNamePrefix, dimensions, region, scale, crs, crsTransform, maxPixels, shardSize, fileDimensions, skipEmptyTiles, fileFormat, formatOptions)
ArgumentTypeDetails
imageImageThe image to export.
descriptionString, optionalA human-readable name of the task. May contain letters, numbers, -, _ (no spaces). Defaults to "myExportImageTask".
folderString, optionalThe Google Drive Folder that the export will reside in. Note: (a) if the folder name exists at any level, the output is written to it, (b) if duplicate folder names exist, output is written to the most recently modified folder, (c) if the folder name does not exist, a new folder will be created at the root, and (d) folder names with separators (e.g. 'path/to/file') are interpreted as literal strings, not system paths. Defaults to Drive root.
fileNamePrefixString, optionalThe filename prefix. May contain letters, numbers, -, _ (no spaces). Defaults to the description.
dimensionsNumber|String, optionalThe dimensions to use for the exported image. Takes either a single positive integer as the maximum dimension or "WIDTHxHEIGHT" where WIDTH and HEIGHT are each positive integers.
regionGeometry.LinearRing|Geometry.Polygon|String, optionalA LinearRing, Polygon, or coordinates representing region to export. These may be specified as the Geometry objects or coordinates serialized as a string. If not specified, the region defaults to the viewport at the time of invocation.
scaleNumber, optionalResolution in meters per pixel. Defaults to 1000.
crsString, optionalCRS to use for the exported image.
crsTransformList, optionalAffine transform to use for the exported image. Requires "crs" to be defined.
maxPixelsNumber, optionalRestrict the number of pixels in the export. By default, you will see an error if the export exceeds 1e8 pixels. Setting this value explicitly allows one to raise or lower this limit.
shardSizeNumber, optionalSize in pixels of the tiles in which this image will be computed. Defaults to 256.
fileDimensionsList, optionalThe dimensions in pixels of each image file, if the image is too large to fit in a single file. May specify a single number to indicate a square shape, or an array of two dimensions to indicate (width,height). Note that the image will still be clipped to the overall image dimensions. Must be a multiple of shardSize.
skipEmptyTilesBoolean, optionalIf true, skip writing empty (i.e. fully-masked) image tiles. Defaults to false.
fileFormatString, optionalThe string file format to which the image is exported. Currently only 'GeoTIFF' and 'TFRecord' are supported, defaults to 'GeoTIFF'.
formatOptionsImageExportFormatConfig, optionalA dictionary of string keys to format specific options.

Examples

Code Editor (JavaScript)

// A Landsat 8 surface reflectance image.
var image = ee.Image('LANDSAT/LC08/C02/T1_L2/LC08_044034_20210508')
                .select(['SR_B.']);  // reflectance bands

// A region of interest.
var region = ee.Geometry.BBox(-122.24, 37.13, -122.11, 37.20);

// Set the export "scale" and "crs" parameters.
Export.image.toDrive({
  image: image,
  description: 'foo_image',
  folder: 'foo_project',
  region: region,
  scale: 30,
  crs: 'EPSG:5070'
});

// Use the "crsTransform" export parameter instead of "scale" for more control
// over the output grid. Here, "crsTransform" is set to align the output grid
// with the grid of another dataset. To view an image's CRS transform:
// print(image.projection())
Export.image.toDrive({
  image: image,
  description: 'foo_image_crstransform',
  folder: 'foo_project',
  region: region,
  crsTransform: [30, 0, -2493045, 0, -30, 3310005],
  crs: 'EPSG:5070'
});

// If the export has more than 1e8 pixels, set "maxPixels" higher.
Export.image.toDrive({
  image: image,
  description: 'foo_image_maxpixels',
  folder: 'foo_project',
  region: region,
  scale: 30,
  crs: 'EPSG:5070',
  maxPixels: 1e13
});

// Export a cloud optimized GeoTIFF (COG) by setting the "cloudOptimized"
// parameter to true.
Export.image.toDrive({
  image: image,
  description: 'foo_image_cog',
  folder: 'foo_project',
  region: region,
  scale: 30,
  crs: 'EPSG:5070',
  formatOptions: {
    cloudOptimized: true
  }
});
