It is typically composed of a basemap layer and data layers.Learn more or sceneA scene is a collection of layers that are displayed in 3D. It is typically composed of a basemap layer, data layers, and 3D data.Learn more. For feature dataFeature data is a general term for one or more features, which are records that represent real-world geographic entities, stored as a feature collection, feature layer, or hosted feature layer.Learn more, a single symbol can be defined for all features or multiple symbols can be defined based on different attribute values. Applying multiple symbols based on data is also called data-driven visualization. There are three basic types of renderers for feature data: (1) simple renderers style all features with the same symbol, (2) value renders style features based on their value, and (3) class break renderers style features based on ranges of numeric values. For raster data, there are a number of different types of renderers, such as stretch, color ramp, and hillshade.
