Export landset image...

[lovechang1986]

Hello, professor,

I want to use your GEEMAP library to export pictures. There are 300 examples in your tutorial. I am a bit confused and I don’t know how to use Google Earth.

Can you give some suggestions based on the picture I gave and which examples should I use?

There are two key points:

1. Add label of localtion, like A in the pic.
2. Display the image acquisition time.

Thank you very much.

Another question: I use this script in jupyterlab, there are some error..

image = ee.Image('LANDSAT/LC08/C01/T1_SR/LC08_038029_20180810')

landsat_vis = {
    'bands': ['B4', 'B3', 'B2'], 
    'gamma': 1.4
}
Map.addLayer(image, landsat_vis, "LE7_TOA_5YEAR/1999_2003", True, 0.7)
# Draw any shapes on the map using the Drawing tools before executing this code block
feature = Map.draw_last_feature

if feature is None:
    geom = ee.Geometry.Polygon([[[-115.413031, 35.889467],
    [-115.413031, 36.543157],
    [-114.034328, 36.543157],
    [-114.034328, 35.889467],
    [-115.413031, 35.889467]]])
    feature = ee.Feature(geom, {})

roi = feature.geometry()
import os
out_dir = os.path.join('/root/Downloads')
filename = os.path.join(out_dir, 'landsat.tif')
geemap.ee_export_image(image, filename=filename, scale=90, region=roi, file_per_band=True)

Error like this:

As the error message indicates, the file size exceeds the limit enforced by GEE. You need to export large images to Google Drive. https://geemap.org/notebooks/11_export_image/#export-an-image-to-google-drive
