How to read-in KML file? (properly)

[illiapolovnikov]

Dear community,

I have a KML file with labeled polygons (~20,000). How can I properly read it into GEE and add as ee.FeatureCollection?
I tried to convert it into shape file so that I could upload it as 'Asset'. However the most important information ends up being stored as some kind of an HTML code.

Any help is much appreciated.
Thanks.

Have you tried the add_kml() function? https://geemap.org/geemap/?h=kml#geemap.geemap.Map.add_kml

[giswqs]

Use kml_to_ee().

Thanks again. Your answers are very valuable.
Unfortunately, kml_to_ee() does not work (it returns Invalid GeoJSON geometry.).
kml_to_geojson() does work. And the resulting dictionary looks like the following:

{'type': 'FeatureCollection',
 'features': [{'id': '0',
   'type': 'Feature',
   'properties': {'Description': '<div class="googft-info-window"> <b>ID:</b> 1<br> <b>class:</b> 1<br> <b>fold:</b> 5 </div>',
    'Name': ''},
   'geometry': {'type': 'Polygon',
    'coordinates': (((77.550514, 8.086537, 0.0),
      (77.550491, 8.086268, 0.0),
      (77.550761, 8.086245, 0.0),
      (77.550784, 8.086514, 0.0),
      (77.550514, 8.086537, 0.0)),)},
   'bbox': (77.550491, 8.086245, 77.550784, 8.086537)},
  {'id': '1',
   'type': 'Feature',
   'properties': {'Description': '<div class="googft-info-window"> <b>ID:</b> 10<br> <b>class:</b> 1<br> <b>fold:</b> 5 </div>',
    'Name': ''},
   'geometry': {'type': 'Polygon',
    'coordinates': (((77.34729, 9.083161, 0.0),
      (77.347313, 9.082892, 0.0),
      (77.347584, 9.082915, 0.0),
      (77.34756, 9.083185, 0.0),
      (77.34729, 9.083161, 0.0)),)},
   'bbox': (77.34729, 9.082892, 77.347584, 9.083185)},
...

Do you know which part of this dictionary leads to the error while trying to convert it to ee object?

[giswqs]

You dataset is in XYZ format. GEE only support XY. You need to get rid of Z.

I hope this would be my last follow-up question. Once I fix the coordinates, the function executes just fine. However, when I try adding my FeatureCollection to the Map, I get:
Request payload size exceeds the limit: 10485760 bytes.

Is there any way around this error?

Thank you so much again.

That's the limit enforced by GEE, not geemap. There is no way around it. You need to either simply the polygons to have few vertices or upload the shapefile directly to your GEE account. See https://developers.google.com/earth-engine/guides/table_upload
