I'm just starting to learn GEE, and I see a number of places use a Fusion Table that has polygons of world countries. It's used in the Google Earth Engine manual, tutorials, and questions on stackexchange. The Fusion Table is
ft:1tdSwUL7MVpOauSgRzqVTOwdfy17KDbw-1d9omPw and can (currently) be found here. But I can't find any reasonable metadata for it. I've tried:
getting the metadata within GEE:
// Country Fusion Table var countries = ee.FeatureCollection('ft:1tdSwUL7MVpOauSgRzqVTOwdfy17KDbw-1d9omPw'); // Get a list of all metadata properties. var properties = countries.propertyNames(); print('Metadata properties: ', properties); // ee.List of metadata properties // Get a specific metadata property. var name = countries.get('name'); print(name); // ee.Number var docid = countries.get('DocID'); print(docid);
But all that it returns is:
Metadata properties: ["name","DocID"] 0: name 1: DocID Countries.csv 1tdSwUL7MVpOauSgRzqVTOwdfy17KDbw-1d9omPw
Going directly to the Fusion Table and going to file > about, which shows this:
Which still says nothing of where the info actually comes from or who created it.
So how do I find out more info about this particular dataset, and how do I evaluate the data quality of Fusion Tables more generally?
