Re: Question: SWOT pixel cloud data product misclassify cropland as water
Thanks for your explanation. I just utilized python matplotlib package for plotting, the same with yours. I think the underlying reason that you cannot find matching pattern with mine is incorrect recognization of geographic coordinate unit for visualization in the bottom figure. Please note that th...

Re: Question: SWOT pixel cloud data product misclassify cropland as water
Thanks for your help and detailed description. Take a deep look into your all illustrations, I find that your last attchment plot (the bottom one) is filtered by "water_frac_uncert" < 0.1, not "water_frac_uncert" < 1.0 (mentioned words in your figure is right but your description...

Re: Question: SWOT pixel cloud data product misclassify cropland as water
Hello, what do you think about this misclassification issue? In my opinion, it may be a research direction related with river channel geometry estimation (i.e., classification, top width) derived from SWOT Pixel Cloud Data Product.

Re: Question: SWOT pixel cloud data product misclassify cropland as water
Thanks for your detailed description. The specific spatial extent is at the end of Daqing River, whose specific longitude range is from 116.875035 to 116.931715 and latitude range is between 39.046942 and 39.065448. This chosen region is not large because it is only used as a demonstration of miscla...

Re: Question: SWOT pixel cloud data product misclassify cropland as water
Thanks for your response. SWOT pixel cloud data utilized here is "SWOT_L2_HR_PIXC_019_200_086L_20240806T215721_20240806T215732_PGD0_01.nc". As for "water_frac_uncert", I did not apply it for open water classification because I find "water_frac_uncert" value between open...

Question: SWOT pixel cloud data product misclassify cropland as water
Hi, all, Recently I find that SWOT Pixel Cloud Data Product (SWOT_L2_HR_PIXC_D) misclassifies cropland (may be characterized with high soil moisture) as water area, which leads to incorrectly wider river channel width estimation if cropland is contiguous with river channel in this situation (see att...

Question about GEDI Level2A dataset update
Dear Sir or Madam, To the best of my knowledge, current most updated GEDI L2A (Elevation and Height Metrics V002) dataset is officially described in Earthdata website (https://www.earthdata.nasa.gov/data/catalog/lpcloud-gedi02-a-002). I have one question to ask: (1) I notice that there is a note in ...
