Export image

[mohanjoshilalit]

Hi,
I was just replicating your code to export an image into my directory. Image exported as well but image size is very small i.e.3KB. if i opening same image in QGIS i can't see any image.

#download an ee.Image
image = ee.Image('LANDSAT/LE7_TOA_5YEAR/1999_2003')
landsat_vis = {'bands':['B4','B3','B2'],'gamma':1.4}
Map.addLayer(image, landsat_vis, "LE7_TOA_5YEAR/1999_2003", True)

Map.draw_last_feature
feature = Map.draw_last_feature
roi = feature.geometry()

out_dir = os.path.join('C:\Projects\EHP\Database\Spatial data')
filename = os.path.join(out_dir, 'landsat.tif')

image = image.clip(roi).unmask()
geemap.ee_export_image(image, filename=filename, scale=90, region=roi, file_per_band=False)

Thanks for your guidance and effort to support this community. Many people are learning from you. I am one of them. Thanks

I am trying clip a DEM and i have catchment area shapefile. I have clipped it but unable to export tiff file.
basin_shp = r'C:\Python learning\SHAPEFILE\Final Layers\Narmada_Basin_Boundary.shp'
basin = geemap.shp_to_ee(basin_shp)
Map.addLayer(basin,{}, 'basin')

roi = ee.FeatureCollection(basin)
clipped_image = image.clip(roi)
out_dir = os.path.join(r'C:\Python learning\SHAPEFILE\Final Layers')
filename = os.path.join(out_dir, 'Narmada dem.tif')
Map.addLayer(clipped_image, vis_params, 'clipped image')

geemap.ee_export_image(
clipped_image, filename=filename, scale=90, region=roi, file_per_band=False
)

Error is:
