[Announcement] Introducing FeatureView assets
Google Earth Engine Announcements
Developers,
Exciting news: we've launched a new asset type called FeatureView!
A FeatureView is a view-only, accelerated visualization of a FeatureCollection with more control over styling and rendering characteristics. Unlike a FeatureCollection, whose raster map tiles are generated on the fly, FeatureView raster tiles are pre-computed, allowing the tiles to begin transferring to the application immediately upon request.
A FeatureView is created by exporting a FeatureCollection. On export, you can set several options that specify feature thinning strategy, max number of features per tile, and overlapping feature display order.
We think that the fast load speed and rendering options will be a nice enhancement to the experience of Earth Engine App consumers as they zoom, pan, and filter data in your apps.
We hope you'll find the styling system nice too. A dictionary of style rules are provided to a FeatureView map layer, which lets you set broad style rules that apply to large groups of features and/or specific rules using filters. Feature style can be defined by constant values or data driven, based on feature attributes.
You can create FeatureView assets from any FeatureCollection, be it a personal asset, Data Catalog table, or a computed FeatureCollection. We've already exported all suitable Data Catalog assets with what we think are broadly applicable settings so that you can start exploring and including them in apps right away.
You can learn more about FeatureView assets in the FeatureView Overview page of the Developer's Guide.
We can't wait to see what you do with FeatureView assets!
