[GIS] Extract land cover data from Google Earth

google earthland-cover

I have latitude-longitude coordinates for a certain region with me. Is it possible that when I enter this data in Google Earth, I can somehow extract the land cover class associated with each coordinate?

Or how can I access the land cover data (if GE already has it online)?

I am new to Google Earth.

As far as I know, Google Earth does not have land use/cover data. It has detailed satellite images that covers most of the globe. You can only visualize your points on Google Earth to see in which region/part of the earth are located. And even if there is a land use/cover data, you still cannot extract those raster information to the point, as you can do in other GIS software like ArcGIS or QGIS.

[GIS] Use Google Earth for land cover classification accuracy evaluation

You're going to be doing accuracy assessment. You want to bring the data for validation (Google Earth) into ArcMap. Then you can "truth" the classification for each of your random points in a shapefile. Afterwards you can sample those same points in your classified image and compute your error matrix.

[GIS] Reducing Land Cover Data Sets in Earth Engine

You can get the "histogram" property (resulting from the reducer) as a Dictionary which can be used to set the landcover:frequency pairs as new properties for a county feature. Then just map that function over all counties in the FeatureCollection.

// Print out the frequency of landcover occurrence for each county
//...

// Optional for debugging: Drop other properties and geometry > simpler looking csv.
frequency = frequency.select(['histogram'], null, false)

var frequency = frequency.map(function(feature){
  var dict = ee.Dictionary(feature.toDictionary().get('histogram'))
  feature = feature.set(dict)
  return feature
})
print('per class landcover frequency properties', frequency)

//Exports table to drive
Export.table.toDrive(frequency, "MaineLandCoverData");
