13 ArcGIS Mobile Workflow Developer Summit

14 ArcGIS Mobile Workflow ArcGIS Server GeoDatabase ArcMap Build Mobile Geodatabase Information and Transaction Model considerations Author Mobile Map (*) Design for environment and form factor Publish Map Service With Mobile Data Access Capabilities Design Mobile Application (*) For Form Factor and Environment Build Data Deployment Packages (*) Operational and base map dataset Deploy Mobile Solution (*) Application and Data Mobile Map Document Synchronize Mobile GIS solution Consider bandwidth and battery life ArcCatalog or Server Manager URL Web Services Mobile Client Developer Summit

15 Author Mobile Map Mobile Map Design Considerations: Design for purpose Remove unnecessary layers of information Set scale dependency based on scales of work (walk, drive, etc) Render editable layers to define feature types Design for the environment Establish contrast, choose meaningful symbology Design for device form factor Set scale dependency based on device resolution Set symbol width based upon device resolution Sunlight washes out Colors 1280x1024 BIG 320x240 Small Determine Base Map Data vs. Operational Data Compress Base Map Data using Create Mobile Base Map GP Tool Build Operational Mobile Cache using Generate Mobile Service Cache Developer ArcGIS Server Summit Final 15

16 Design Mobile Application Mobile SDK installed as part of ArcGIS Server Use Visual Studio 2005/2008: Windows Mobile 5.0 for Pocket PC Windows Mobile 6.0 Professional Pocket PC 2003 Windows Mobile 5.0 for Smartphone Windows Mobile 6.0 Standard Tablets and Notebooks (XP/Vista) IDE Integration Build Simple and focused user interfaces Develop for function and form factor Developer Summit

17 Build Data Deployment Packages New Mobile Toolset inside of Desktop ArcToolbox Create Mobile Base Map Tool Creates a Base Map Data Set to be provisioned on mobile devices as base map layers Support large base map datasets Generate Mobile Service Cache Tool Creates a mobile service cache for all operational layers Uses published mobile web service as input and extracts layers Developer ArcGIS Server Summit Final 17

18 Deploy Mobile Solution ArcGIS Server Mobile EXE Data Deployment Package Visual Studio Deployment GP Tools Use Standard Deployment Technology ActiveSync, Windows Mobile Device Center Mobile EXE Data Microsoft SMS SOTI MobiControl Secure server and client data Developer Summit

19 Synchronize Mobile GIS Solution Application: Takes responsibility for managing the sync process Pushes and pulls new and updated features Leverages spatial and attribute queries to optimize feature pull from the Server ArcGIS Server Day to Day Sync Developer Summit

20 Best Practices Mike Developer Summit

21 General UI Design Guidelines Mapping device screens to device forms Screen layout/orientation awareness Closing form Form navigation Handling input appropriately to boost productivity Taps SIP Hardware key/keyboard Menu vs. Tool considerations Developer Summit

22 General Coding Guidelines Multiple threaded environment Use BeginInvoke to push arguments to the UI Dispose of objects that implement IDisposable Wrap inside using block Use try catch blocks where appropriate Employ defensive coding practices Optimizing performance Understand garbage collector in.net CF Developer Summit

23 Best Practices Working With Maps Developer Summit

24 Map and MobileService Base Map Management Map Display MobileService Layers Map component draws data from local cache managed by MobileService (threaded drawing) MobileService stores map data on device MobileService component synchronizes updates with server Map component supports markup/graphics on Display Map component supports drawing of custom layers Map rotation supported Developer Summit

25 Synchronize Tips Use Request_Completed event to monitor synchronization requests Succeed or fail Statistics for each request Use the State and Notifications Broker API and be smart about how connected you are Microsoft.WindowsMobile.Status Developer Summit

26 Best Practices Working With Maps The Simple Demo (Jay) Developer Summit

27 Demo Summary: Working With Maps IDE Integration Toolbox components with design time properties MapAction components encapsulate core tools write less code! Maps Map data drawn from local map cache MobileService component manages synchronization with the server Drawing is multi-threaded, threaded, UI is responsive! Use MapCache::Request_Completed event!

37 Best Practices Fusing Data Using Web Services Developer Summit

38 Custom Layers Provide ability to fuse data into the map Data sources other than ArcGIS Server Data does not reside inside the local cache. Provides framework to read and draw your data Examples: Dynamic Data (Live traffic, GeoRSS, etc) Web Services Data (Virtual Earth basemap, ArcWebServices POI) ArcGIS Server Web Services (Geoprocessing, Network, etc) Developer Summit

39 Best Practices Fusing Data Using Web Services Live Traffic Demo Developer Summit

40 Demo Summary: LiveTraffic Uses Webservice to request live traffic data Employs Custom Layer Data Storage outside the cache Over-ride ride Draw() Add to Map.MapLayers() User defined symbology Developer Summit
