offline map

An offline map is a map area and its data content downloaded from an offline-enabledOffline-enabled is a setting in a web map or hosted layer item that allows it to be downloaded and used by offline apps.Learn more web mapA web map is a map stored as a JSON object that defines properties such as the basemap layer, data layers, layer styles, and pop-up styles. Its JSON structure is defined by the web map specification.Learn more for use in offline applicationsAn offline application, also known as offline app, is an application that runs on a phone, tablet, laptop or desktop device with limited or no network connection. Offline applications are built with ArcGIS Maps SDKs for Native Apps.Learn more. Offline maps are used by partially offline apps built with ArcGIS Maps SDKs for Native AppsArcGIS Maps SDKs for Native Apps, previously known as ArcGIS Runtime SDKs, are developer products for building mapping and spatial analysis applications for native devices.Learn more as these apps require a network connection to perform the initial download. Once downloaded into the device, the map can be used without a network connection, for example, when working in the field. When a network connection is re-established, edits that were made in the offline map can be synchronized with the source web map. Offline maps can be downloaded into the device using these two development patterns:

• Defining map areas ahead-of-timeThe ahead-of-time workflow, also known as the preplanned workflow, is a development pattern for building offline applications where offline map areas in a web map are used by the offline application.Learn more: The web map author defines areas within the web map to be packaged as offline maps. These areas are called offline map areasAn offline map area, also known as a preplanned map area, is an area in a web map used to create an offline map.Learn more. Then, the offline app will download one of the offline map areas that the web map author has defined.
• Defining map areas on-demandThe on-demand workflow is a development pattern for building offline applications where the offline application defines an area of a web map to take offline.Learn more: The offline app will define an area of the web map to take offline. Then, ArcGIS Maps SDKs for Native AppsArcGIS Maps SDKs for Native Apps, previously known as ArcGIS Runtime SDKs, are developer products for building mapping and spatial analysis applications for native devices.Learn more will generate an offline map from the specified area and download it. The web map author has no involvement in this process.
