1 ArcGIS Runtime SDKs Building Offline Apps Nick Furness

2 Agenda The basics - Considerations - Building blocks - Service types New! Offline maps New! Preplanned workflow

3 What we are covering and what not We are focusing on maps and the new workflows - Previously working with layers and tables directly (still can) - Focus moved to map instead Support for offline data formats hasn t gone anywhere - Tile packages, Vector tile packages, Rasters, Geodatabases Even more data types are now supported - OGC GeoPackages, Shapefiles, Electronic Navigational Chart (ENC) - Vector tiles export Check previous session recording from video.esri.com search term : ArcGIS Runtime: Working with Maps Online and Offline

4 Design for connectivity Make connectivity part of the application strategy Connected Disconnected Occasionally connected Temporary interruptions due connection problems Plan work as if in disconnected environment

5 What is a map? Central concept in ArcGIS Can be shared between multiple applications Contains - Basemaps - Operational Layers - Symbology - Popups - Metadata Authoring is done usually outside of Runtime - Can be updated outside of client application update cycle

6 Maps workflows Connected Connected maps - Distributed through Portals On-demand map areas - Generated and downloaded on request basis Preplanned map areas - Prepackaged using ArcGIS API for Python or Geoprocessing tools - Downloaded using ArcGIS Runtime Fully disconnected maps - Authored using ArcGIS Pro - Side loaded to the devices NOTE These are main workflows so mixing these are possible and practical. Disconnected

13 Supported data types Vector tiles Features Feature collections Raster tiles Tables

14 Enable for offline Service authors have to enable support for offline use - Raster and Vector Tile Services NOTE You can enable offline mode at publishing time or from the service management tools. - Feature services Locators and Network datasets have to be side loaded to the device

24 Edit and Sync

25 How Does Sync Work? The flow of data Apply response to geodatabase Feature service with sync enabled Retrieve response Upload delta Call Sync Generate geodatabase enabled for sync Adds, edits, deletes Generate delta geodatabase

28 Working with disconnected maps

29 Desktop pattern Read-only workflow Mobile Map Packages authored with ArcGIS Pro Locators and network dataset needs to be created with this pattern Has to be side loaded to the clients Street Map Premium for ArcGIS offers very good dataset for disconnected scenarios - Contains basemap - Locator - Network dataset

30 Summary - Preplanned workflow is complementing the offline story not replacing it - Use Preplanned workflow if you can plan the work and/or the work is done in the same areas - Use On-demand workflow if you need to provide support for ad-hoc offline work - Try to adapt the WebGIS pattern since it is the most versatile way to provide maps that works well both in online and offline modes - Take the connectivity design as a core requirement for your system and applications - Hybrid approaches work well choose the approach based on YOUR requirements
