2 Outline What is ArcGIS Explorer Premier client to ArcGIS Server Programming custom tasks Software developer kit Objects in the Explorer API Task Framework Creating custom tasks Task lifecycle Typical customizations consuming geoprocessing services integrating web services Extending ArcGIS Explorer using OpenGL Task deployment, security and tips ESRI Developer Summit

3 What is ArcGIS Explorer? Free to deploy, lightweight, easy to use 3D desktop application A client for ArcGIS Server Easy way to deliver access to GIS content and capabilities, integrate, and utilize GIS services, geographic content, and other web services. More than an exploration tool, it s s a way to deliver and publish ArcGIS capabilities to your users ESRI Developer Summit

4 ArcGIS Server 9.2 Software Development Kits Build web & enterprise geospatial applications and services Productivity boost with out-of of-the-box IDE integration Software Development Kit (SDK) includes :.NET components Web ADF Mobile ADF ArcGIS Explorer SDK Java components Web ADF Enterprise ADF Web WebMap Applications.NET Mobile ArcGIS Mobile Integration Environment Web Java Software Development Kit (SDK) ArcGIS Explorer Explorer SDK Enterprise ESRI Developer Summit

8 Customizing ArcGIS Explorer Developers Create Custom Tasks to connect to web services Can also Refine existing user interface Perform local operations i.e. Read shapefiles, render OpenGL ESRI Developer Summit

9 Defining Tasks Tasks perform a function, by Asking the question Displaying the answer (results window) Tasks are lightweight Less code on the client Use servers to get their job done SDK includes a blank custom task template ESRI Developer Summit

10 ArcGIS Explorer API Object model exposed in managed API ESRI.ArcGIS.E2API namespace/assembly Not GAC d d (allows non-admin install) Managed task loading framework Each task in own AppDomain All AppDomains unloaded on document close Implications for multiple-task task assemblies Task framework is multi-threaded threaded Many tasks executing simultaneously Responsive user interface Framework design avoids third party thread programming ESRI Developer Summit

11 ArcGIS Explorer Object Model Application classes what you can do to control / interact with the application Task Framework how you incorporate your tasks into the Application Task framework is the only customization point in Explorer ESRI Developer Summit

12 The Software Developer Kit ArcGIS Explorer.NET SDK provides resource to create custom tasks Conceptual Documentation Component Help Visual Studio Integration Object Model Diagram Sample tasks and code snippets ESRI Developer Summit

15 How a task works - outline 1. Task UI gathers the inputs 2. Task UI creates a Task Context and populates it with inputs 3. TaskUI tells application to process TaskContext 4. Application creates Task and executes it task execution happens in a separate thread (may or may not be needed depending on your task) 5. Task performs operation and creates Results 6. Results displayed in application ESRI Developer Summit

16 Custom task architecture E2API namespace System.Windows. Forms namespace TaskUI Task UserControl MyTaskUI MyTask MyControl Custom task project namespace ESRI Developer Summit

17 Custom Task Introduction demonstration Introduction to the Custom Task Framework ESRI Developer Summit

18 How a task works - task lifecycle User initiates a task 1 Task is restarted 2 TaskContext lifetime Task lifetime Task is stopped prematurely ESRI Developer Summit

19 Task Lifecycle demonstration Lifecycle of a Task ESRI Developer Summit

21 Consuming Geoprocessing Services Accessing Geoprocessing Services via the UI using the Manage Tasks dialog custom task creation in Visual Studio, make a web reference to the service. utilize ArcGIS Explorer s s multithreading environment to keep the user interface interactive whilst waiting for the results from ArcGIS Server. ESRI Developer Summit

Geoprocessing Client - Server asynchronous request lifecycle Client Client requests job status Submit request to the server SOM tells client job was submitted Client waits for job to

22 Geoprocessing Client - Server asynchronous request lifecycle Client Client requests job status Submit request to the server SOM tells client job was submitted Client waits for job to finish Results sent to client GIS Server SOC executes job Job ID and job created Jobs directory created SOM arcgisjobs arcgisjobs SOC SOC SOC Jobs directory remains ESRI Developer Summit

23 Geoprocessing demonstration Accessing and using a published geoprocessing service ESRI Developer Summit

24 Integrating web services This is the aim of custom task framework.net language ideal for programming against web services SOAP/ASP.NET ideally REST also simple to program against ESRI Developer Summit

30 Task Deployment Explorer can automatically download and run tasks from the internet Allows non-admin deployment Can have multiple tasks in one task assembly allows one task to call another Can have multiple versions of same task installed on machine at once even in same map - but best practice to avoid this ESRI Developer Summit

31 Deploying custom tasks demonstration Auto-download and setup ESRI Developer Summit

32 Task Security Explorer can automatically download and run tasks from the internet Allows non-admin deployment You get a warning in the application Tasks run in Local Machine security context A Home Server can prevent the ability to download code from Internet Intranet Trusted Sites (IE) ESRI Developer Summit

33 Tips Problems in tasks loading / showing up: DebugLog setting: Key: HKCU\Software Software\ESRI\E2\Settings Value: DebugLog Data: 1 (DWORD) Outputs log to ArcGIS Explorer folder in profile Make sure in the project references the E2API has CopyLocal and SpecificVersion set to False 'Deployment Troubleshooting' topic in help ESRI Developer Summit

34 Tricks ServerStyles adding 3D content ArcGIS Explorer uses 2D and 3D serverstyles Using Google Sketchup use Sketchup to create or search the 3D Warehouse for a model. Using ArcMap convert the model into a style Style conversion convert your style file into a serverstyle for ArcGIS Explorer use ESRI Developer Summit

35 ServerStyle demonstration 3D ServerStyle creation and use ESRI Developer Summit

36 In Summary Entry point to API is custom Task/TaskUI Simple API on client Task Framework is key Make maximum use of server side power and functionality Automatic downloading of tasks straightforward deployment, think security ESRI Developer Summit
