}Map API
Weather Map API provides global weather forecast, radar and satellite data as map tiles compatible with commonly used map services such as Open Street Maps or Google Maps. All required and optional parameters are given as path and query parameters respectively. To obtain images one must first request an access token using valid credentials. The access token can then be used to fetch capabilities-response, which contains information on how to fetch images.
Capabilities
Capabilities endpoint is used to fetch layer metadata. This metadata is used to perform image queries. Capabilities-response provides layer information such as description, temporal and spatial extents as well as available color schemes. Images are layers renderable to image formats such as png or svg. The current data property in time element is the index to the most recent available time. Image products may have additional color schemes which can be optionally specified.
