Functions¶
// Import geetools-code-editor Batch module
var batch = require('users/fitoprincipe/geetools:batch');
Data Acquisition & Preprocessing¶
// Set area of interest (AOI)
var rmnp_boundary = ee.FeatureCollection("users/calekochenour/Rocky_Mountain_National_Park__Boundary_Polygon");
// Filter Landsat 8 based on dates and AOI
var rmnp_collection = ee.ImageCollection('LANDSAT/LC08/C01/T1_SR')
.filterDate('2020-06-01', '2021-01-21')
.filterBounds(rmnp_boundary);
print("Image Collection", rmnp_collection);

Data Export¶
// Set export folder (relative to Google Drive root folder)
var output_folder = 'gee-export';
// Export collection image to Drive
batch.Download.ImageCollection.toDrive(
rmnp_collection,
output_folder,
{
name: '{id}', // {id}, {system_date} and all other properties (e.g., {WRS_PATH})
// dateFormat: 'yyyy-MM-dd', // Default
