How to combine two featurecollections in Google Earth Engine?

How to combine two featurecollections in Google Earth Engine?

Tutorials contributed by the Earth Engine developer community are not part of the official Earth Engine product documentation. This basic tutorial shows how users can combine two ee.FeatureCollection s into a new ee.FeatureCollection. Let’s begin by generating two sets of random points within the boundary of Utah state in the USA.

How to combine two image collections into one?

I tried the solution in the link, and while the join is successful, it doesn’t seem to be able to add the second band. Is it because the metadata of the two imageCollections are different ?

How to combine two ee.featurecollections into one?

This basic tutorial shows how users can combine two ee.FeatureCollection s into a new ee.FeatureCollection. Let’s begin by generating two sets of random points within the boundary of Utah state in the USA. First, define the boundary of Utah as a geometry.

Is there a cookbook for Google Earth Engine?

The following Beginner’s Cookbook, created by Chakraborty on Google Developers, presents several types of geospatial data and key Earth Engine functions for analysis and visualization. The cookbook was originally created as a workshop during Yale-NUS Data 2.0 hackathon, and later updated for Yale GIS Day 2018 and 2019:

Who is the researcher for Google Earth Engine?

TC Chakraborty, PhD Candidate at the Yale School of Forestry and Environmental Studies and Researcher at Data-Driven Lab, led a workshop that introduced participants to geospatial analysis and algorithm development using Google Earth Engine’s Javascript API.

What do containers do in Google Earth Engine?

A container object (usually in the form ee.SomeVariableType) is used to wrap a native JavaScript object so that Google’s servers can perform operations on it. The print operation is also useful for printing data and getting debugging info.

How to map the area over a featurecollection?

// Map the area getting function over the FeatureCollection. // Print the first feature from the collection with the added property. In the previous example, note that a new property is set based on a computation with the feature’s geometry. Properties can also be set using a computation involving existing properties.

What kind of geometries does Google Earth Engine support?

The GeoJSON spec describes in detail the type of geometries supported by Earth Engine, including Point (a list of coordinates in some projection), LineString (a list of points), LinearRing (a closed LineString ), and Polygon (a list of LinearRing s where the first is a shell and subsequent rings are holes).
