How are features and featurecollections used in GeoJSON?
Features in GeoJSON contain a Geometry object and additional properties, and a FeatureCollection contains a list of Features. Leaflet supports all of the GeoJSON types above, but Features and FeatureCollections work best as they allow you to describe features with a set of properties.
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 add geometry to the drawing tools?
There are two ways to add new geometry layers to the drawing tools: // Use the addLayer method on the drawing tools directly. // Create a new GeometryLayer and add it to the layers list. // Print the list of geometries. // Add a geometry to the layer.
Which is the best type of GeoJSON for leaflet?
Leaflet supports all of the GeoJSON types above, but Features and FeatureCollections work best as they allow you to describe features with a set of properties. We can even use these properties to style our Leaflet vectors.
The value corresponding to “features” is an array. A geometrycollection is a single feature (which you could contain in a featurecollection): A GeoJSON object with the type “Feature” is a feature object. A feature object must have a member with the name “geometry”.
What are the different types of GeoJSON data?
GeoJSON is a format for encoding a variety of geographic data structures […]. A GeoJSON object may represent a region of space (a Geometry), a spatially bounded entity (a Feature), or a list of Features (a FeatureCollection). GeoJSON supports the following geometry types: Point, LineString, Polygon, MultiPoint, MultiLineString,…
