Google Earth Engine – How to Import Imagery from Google Cloud Buckets

google-cloudgoogle-earth-engine

I have several images stored in a Google Cloud bucket that I would like to import into Google Earth Engine. In the GEE documentation, I can see that Earth Engine can ingest single images from a Bucket using ee.Image.loadGeoTIFF() but I have too many images for this to be feasible.

Is there some way import all images in a Bucket as an imageCollection, or to loop through all possible names for images to and add them one-by-one to an imageCollection?

Would it be faster to just download from the bucket and separately upload to Earth Engine?

You can add them to a collection, but only by calling the createAsset endpoint yourself. https://developers.google.com/earth-engine/Earth_Engine_asset_from_cloud_geotiff

There is not a heatmap function that I know of in Earth Engine but you can create your own using some neighborhood operations that are available in EE. Here is an example:

// 'fc' is the feature collection of points
var points = fc.map(function(feature){
  return feature.set('dummy',1);
});

function heatmap(fc,radius){
  var ptImg = points.reduceToImage(['dummy'],ee.Reducer.first()).unmask(0);
  var kernel = ee.Kernel.circle(radius);
  var result = ptImg.convolve(kernel);
  return result.updateMask(result.neq(0));
}

var heatmapImg = heatmap(points,20);

var gradient = ['lightgreen','yellow','red'];

Map.addLayer(heatmapImg,{palette:gradient,min:0,max:0.02},'Heatmap');

[GIS] Google Earth Engine: How to import data from Google Cloud Storage

As the suggestion first line indicated:

Running command using Cloud API. Set --no-use_cloud_api to go back to using the API

And according to the hint the source code imply that '''--no-use_cloud_api''' is used for Disables the new experimental EE Cloud API backend( https://github.com/google/earthengine-api/blob/master/python/ee/cli/eecli.py)

Therefore, there are some differences between old and new version of this API.

!earthengine --no-use_cloud_api upload image --asset_id={outputAssetID} {outputImageFile} {outputJsonFile}

finally using this code works.
