Layer

A layer is a logical collection of geographic data that can be accessed by users and applications, displayed in maps and scenes, and used to perform different types of analyses. Layers are typically stored and managed in ArcGIS Online and ArcGIS Enterprise as items so they can be easily shared. Layers can be broadly categorized into two groups: layers that contain vector data (i.e. data that includes geometry and field attributes) that can be queried and edited (e.g. Feature Layers); and layers that contain raster data (e.g. Image Layers).
