  1. 2006 Indiana GIS Conference The Real-World of ArcGIS ServerImplementing ArcGIS Server Applications March 8, 2006 Joe LaCombeWoolpert, Inc.

  2. Goal • What is ArcGIS Server? • ESRI product comparison • ArcGIS Server Architecture • Why use ArcGIS Server? • Creating applications • Issues • Future

  3. What is ArcGIS Server? • ESRI’s answer to Enterprise GIS • One core, many clients • Server deployment of ArcObjects. • Used for developing server-side applications • Centrally managed applications • Supports multiple user editing, advanced GIS analysis and geoprocessing (also via web) • Can be accessed across LAN or the Internet.

  4. ESRI product comparison ArcGIS Desktop ArcGIS Engine ArcGIS Server Desktop GIS ArcMap ArcCatalog Building blocks Enterprise GIS ArcObjects

  5. ArcGIS Server Architecture GIS server—Hosts and runs server objects. The GIS server consists of a server object manager (SOM) and one or more server object containers (SOCs). ArcGIS Server Object Container Calling Application

  6. Server Objects • Map Server • Geocode Server • Server objects are equivalent to ArcIMS Map Service Map Server Object ArcGIS Server Object Container Geocode Server Object

  7. Server Objects, Pooled vs. Non-Pooled Pooled Non-Pooled Calling Application MapServer 1 MapServer 1 Instance1 Instance2 Instance3 Instance4 Instance1

  8. Server Objects, cont. • Pooled is faster; works if you are not editing data or changing state • Non-pooled will return you a new instance of the object for each request. Use for editing or changing state of the object • Ex. – Mapping Application • User does not add/remove layers, or change text/graphics on layout – Pooled • User needs to add/remove layers or personalize their layout – Non-Pooled

  9. Creating applications • Web-based viewer • Web services

  10. Web-based Viewer Map Server Object ArcMap on the web • Editing • Advanced GIS Analysis • High-quality map creation and printing • Centrally managed

  11. Web-services web Geocode Web Service Map Server Object Database ArcGIS Server .Net Web Service Geocode Server Object Spatial Selection Web Service Desktop Enterprise GIS • Service oriented architecture • Standard input and output • One place, accessible by all • Eliminates duplicate functionality

  12. Issues • Performance when it comes to some things – Exporting maps, performing heavy processing • Sometimes tricky to communicate between other servers and the ArcGIS Server - Impersonation • Initial learning curve – new product

  13. ArcIMS vs. ArcGIS Server ArcIMS • According to ESRI, ArcIMS is solely for “the geopublishing of maps, data, and metadata. Its goal is to deliver data to many users on the Web.  ArcIMS is the solution for delivering dynamic maps, data and metadata via the Web”. • Tested and tried • Right now, lowest cost for Internet mapping • Supported Extensions – Routing, Data Delivery • However, its architecture doesn’t fully support the implementation of an enterprise-wide GIS.

  14. Which one to choose? Scenario 1 • You are a utility company with 50+ field crew. • You need a simple web-based viewer that can also be accessed via a mobile, wireless connection. • The field crew needs real-time tracing of utility network and isolation of assets. • The field crew probably needs some basic routing to get to assets in the field. • Possible recommendation – ArcGIS Server

  15. Which one to choose? Scenario 2 • You are a utility company with 50+ field crew. • You need a simple web-based viewer that can also be accessed via a mobile, wireless connection. • The field crew probably needs some basic routing to get to assets in the field. • Possible recommendation – ArcIMS

  16. Future • 9.2 • Improved drawing speed • Ability to set a minimum number of Non-pooled object instances – pre-created • Setting the maximum number of instances at one time – machine memory • Mobile ADF • Web Application Developer Framework (ADF) has been re-architected

  17. Future Web ADF • Web controls have been re-architected to work with ArcIMS map services and ArcWeb Services • ArcIMS libraries have been added to the web ADF to enable the ability to develop against ArcIMS map services • Write ArcIMS applications completely in the .Net framework, without having to write ArcXML • One core, one development environment  Simultaneously write an application that uses both ArcGIS Server and ArcIMS
