Connected

Always disconnected

Occasionally disconnected

• Temporary interruptions due to connection problems• Deliberate remote working• Plan work as if in disconnected environment

Design for connectivityMake connectivity part of your application strategy

• Central concept in ArcGIS• Authored using the ArcGIS Platform• Can be consumed by multiple applications• Updates can be shared• Contains

- Operational Layers- Feature layers

- Basemap Layers- Tiled layers- Vector tiled layers

- Metadata

Item info

Mobile map packageOffline

• Always Disconnected maps- Authored using ArcGIS Pro- Side loaded to the devices- Read only- Mobile Map Packages

• Occasionally Connected maps- Authored using ArcGIS Online/Portal- Downloaded to device using ArcGIS Runtime- Edit and Sync enabled- Mobile Map Packages

Offline workflows

Always Disconnected

• Mobile Map Packages authored with ArcGIS Pro• Supports Read-only• Has to be side loaded to the client device

• NOTE:- Locators and transportation networks need to be created with

this pattern- Street Map Premium for ArcGIS offers very good dataset for

disconnected scenarios - Contains basemap- Locator- Network dataset

ArcGIS Pro

• Geoprocessing Tool• Data Management Toolbox• Package Toolset• Create Mobile Map Package

ArcGIS Runtime for iOS 100.4

Demo :

Displaying maps from a mobile map package

MobileMapPackage (Path to mobile map package file)

MobileMapPackage.load (…and wait)

mapView.map = MobileMapPackage.maps[0]

Display a mobile map package !

• Always Disconnected maps- Authored using ArcGIS Pro- Side loaded to the devices- Read only- Mobile Map Packages

• Occasionally Connected maps- Authored using ArcGIS Online/Portal- Downloaded to device using ArcGIS Runtime- Edit offline- Sync (when reconnected)- Mobile Map Packages

Offline workflows

!

Occasionally connected maps

• Web map authored in ArcGIS Online or Portal

• Support Take Map Offline and Enable Editing and Sync

• Downloaded as a Mobile Map Package

• Two workflows:- Preplanned – author defines offline map- On-demand – user defines offline map

Data types that can be taken offline

Feature collections

Vector tiles

Tables

Features

Raster tiles

Allow map and data to be taken offline• Web Map settings

• Service settings- Raster and Vector Tile Services

ArcGIS Runtime SDK for Qt 100.4

Demo :

Take map offline on-demand

On-demand Workflow code

OfflineMapTask (webmap)OfflineMapTask.load (…and wait)

Parameters = OfflineMapTask.createDefaultParameters(AOI, scale) (…and wait)Parameters.includeBasemap = falseParameters…

Job = OfflineMapTask.generateOfflineMapJob(Parameters, download path)Job.start() (…and wait)mapView.map = Job.result.offlineMap

Edit and Sync an Offline Map

Author

Preplanned or On-demand Workflow

Edit

Synchronize• Bi-directional• Upload edits only• Download changes only

OfflineMapSyncTask(offlinemap)OfflineMapSyncTask.load() (…and wait)

OfflineSyncParameters.syncDirection = BiDirectional

Job = OfflineMapSyncTask.syncOfflineMap(OfflineSyncParameters)

Job.start() (…and wait)

Synchronize the whole Offline Map

OfflineMapSyncTask

• Targets every feature layer in the map• Simply with limited options• Designed to work with OfflineMapTask

Editing supportedSynchronize changes – Bidirectional, Upload, Download

Licensing at Basic Level(View only? Licensing at Lite Level)

On-demand workflowUser defines map on ad-hoc basisResponsive to users situationLots of control over the map and individual layersDownloaded map content is always current

Occasionally connected map workflows

Preplanned workflowManager defines map areas ahead of workFaster downloadReduces the load on the Server as map generation can be scheduledMany users can download the same mobile map package

Advanced – for even more control!• Take individual layers offline

• Tiled ArcGIS Map service- ExportTileCacheTask- Tile package (.tpk)

• ArcGIS Vector Tile services- ExportVectorTilesTask- Vector tile package (.vtpk) and their associated style resources

• Feature Layer- GeodatabaseSyncTask- Sqllite geodatabase (.geodatabase)

- Account for connectivity when designing your application- Connected- Always Disconnected

- Occasionally Connected- Preplanned- On-Demand- Sync Map- Take individual layers offline
