How to map a feature over a featurecollection?
// Load watersheds from a data table. // This function computes the feature’s geometry area and adds it as a property. // Map the area getting function over the FeatureCollection.
How are feature collections used in Google Earth?
Groups of related features can be combined into a FeatureCollection, to enable additional operations on the entire set such as filtering, sorting and rendering. Besides just simple features (geometry + properties), feature collections can also contain other collections.
Is there any way to convert hand-drawn geometries into an ee.featurecollection?
Is there any way to convert hand-drawn geometries into a ee.FeatureCollection, ee.Geometry or something similar; in order to be used at the first instance and without having to re-run the script after drawing?
How are drawn geometries added to a web app?
Those drawn geometries are added as objects in the code, but not layers that can be interacted with via the ui.* methods. One solution is to build a stand-alone web app that automatically adds a drawn geometry as a layer.
How to create featurecollection in Google Earth Engine?
Individual geometries can also be turned into a FeatureCollection of just one Feature: // Create a FeatureCollection from a single geometry and print it. Earth Engine hosts a variety of table datasets.
What kind of geometries are supported by Gee?
The GeoJSON spec describes in detail the type of geometries supported by GEE, including Point (a list of coordinates in some projection), LineString (a list of points), LinearRing (a closed LineString), and Polygon (a list of LinearRings where the first is a shell and subsequent rings are holes).
Which is the best way to interact with Gee?
There are several ways to interact with GEE: In my opinion, the Python wrapper library (used in this post) is the best choice to interact with GEE for the following reasons: Easy to share code. Easy transition to a web application.
