How to download big-size image?

[lg760411]

Dear Dr. WU,
When I download my classifed image to local drive with "geemap.ee_export_image", it fail because the size of the image is too big. How can I download big-size image?
Another question, Is it possible to import the image in local drive to Jupyter, like that of shp?

For exporting large image files, use ee_export_image_to_drive(). See notebook example https://geemap.org/notebooks/11_export_image/#Export-an-image-to-Google-Drive.

For dealing with local raster files, see the following:

• https://geemap.org/notebooks/25_load_rasters
• https://geemap.org/notebooks/68_netcdf_to_ee
• https://github.com/giswqs/geemap/blob/master/examples/notebooks/numpy_to_ee.ipynb

Why ee_export_image_to_drive() can download large images, but ee_export_image() cannot?

Dr. Wu,

I have a similar question.
I used a Landsat tile to extract images from different satellites. Then, I add each image to a band like below. So, how can I download the joined images as a CSV file to my local computer?
I have tried different methods. Now, only downloading the joined images with a 210-m pixel scale separately works.
Do you have any suggestions or comments? Very appreciated!

img_joined = img_initial.addBands(img_2).addBands(img_3).addBands(img_4).addBands(img_5).addBands(img_6).addBands(img_7).addBands(img_8).addBands(img_9).addBands(img_10).addBands(img_11).addBands(img_12).addBands(img_13)
geemap.ee_export_image(img_joined, filename="TEST.tif", scale=30, region=region, file_per_band=False)

P.S. This questions is also posted at https://gis.stackexchange.com/questions/467222/how-to-download-a-joined-image-as-a-csv-file-on-my-local-computer

ee_export_image() uses the Earth Engine ee.Image.getDownloadURL function, which runs in the interactive environment. The interactive environment is intended to give quick responses, therefore there are limits on the amount of data that can be returned and the time it takes. When exporting to Drive, the batch environment is used, which permits much larger requests.

@RuiGao9 please post your CSV file download question to a new thread. It is a little off-topic.

Hi @jdbcode, please take a look at my question at your convenience.

So far, I have tried several different methods (https://geemap.org/notebooks/11_export_image/#extract-pixels-as-a-numpy-array), but none of them provided me the CSV file :(

How to keep the band names when download the images? I found the band names was changed to 'Band1','Band2'...

Band names are assigned by GEE, not geemap. You can rename the band names before exporting image if needed.
