I’m a relatively new user of Google Earth Engine, although have some experience coding in R. I’m trying to merge several ee.FeatureCollections with identical property labels, as seen in a brief example using trees below.
I’ve first defined two Feature Collections (random points, just to illustrate the problem), setting two properties for each: a ‘type’ and a ‘status’ label with associated values.
var trees = ee.FeatureCollection(ee.Geometry.Point([-122.22599, 37.17605])).set('type','Sycamore').set('status', 'dead');
var trees2 = ee.FeatureCollection(ee.Geometry.Point([-125.3456, 38.16578])).set('type','Aspen').set('status','alive');
I then merge the two Feature Collections:
var treesMerge = trees1.merge(trees2);
However, when I print the merged collection, the properties associated with each Feature have not be carried over from the individual Feature Collections – see link to screenshot of printed results.
print(trees1); print(trees2); print(treesMerge);
Is there a way to merge Feature Collections that preserves these properties?
