HERE Platform stores data in catalogs. A catalog is a collection of data that is managed as a single set. Catalogs contain layers that represent different types of data. In the case of map data, layers can be overlaid spatially to construct a complete digital map. For example, a catalog may contain a map that includes layers for road attributes, topology, and signs. While catalogs often contain geospatial data, catalogs can contain any kind of data.
A layer is a set of partitions of a specific data type, functional property, and structure. There are five types of layers: versioned, volatile, index, stream, and object store. Each layer relates to a set of billable cloud services which accrue costs when used. See Layers for more information.
Pipelines also relate to a set of billable cloud services which accrue usage costs based on the amount of data used as measured in Gigabytes (GB). A pipeline is an executable data processing application that is designed to run on a streaming or batched processing framework. This application is commonly referred to as a pipeline because it channels the data input through a defined sequence of manipulations and transformations that have a single end point. Many components go into making a pipeline. See the Pipelines Developer's Guide for more information on pipeline concepts.
The following figure provides a high-level mapping overview of HERE Platform components to their respective billable cloud services.
See Billable Cloud Service Descriptions for more information on billing rates and service costs for cloud services.
