Overview Rollout Schedule IndianaMap R3 development began in Fall 2010. IndianaMap R3 Beta testing will begin this Spring. IGIC members will be invited to be Beta testers. IndianaMap R3 Release is scheduled for the summer of 2011. IndianaMap R3 Road Shows and Webinars Demonstration and training sessions will be scheduled shortly after formal release.

Design and construction ArcGIS Server 10.X Why ArcGIS Server? Contracted by Indiana Office of Technology (IOT) ArcIMS 10 does not publish MXD s Allows more flexible organization of datasets Widely disseminate access to the public Is it faster? Is it more stable?

Design and construction Performance Optimized map service average response time: 0.69 seconds ArcIMS map service average response time: 0.83 seconds Standard map service average response time: 2.21 seconds From ESRI White Paper, August 2009

Design and construction Silverlight Silverlight versus Adobe Flex or Javascript Why Silverlight? Long term sustainability Rich internet application Client side plug in handles many tasks previously performed on the server Improves responsiveness

Definition of terms Basemap Gallery Definition Basemaps are predesigned maps that serve as the background for a custom map. Role or function Each basemap is made from multiple layers fused into a cached service Makes construction of custom maps faster and easier Types that will be available on IndianaMap Aerial photos Topographic maps Hillshaded relief Public Land Survey System More to come

Definition of terms Definition A collection of thematic maps. Map Gallery Thematic maps are a prebundled collection of related layers that can be superimposed on a basemap. Function Speeds up the production of a custom map. Examples Watershed Coordinators Thematic Map Public Safety Thematic Map

Advanced features REST Services (Representational State Transfer) Definition A unique URL for a GIS map service published with ArcGIS Server. It can be used to serve a single GIS layer, or a collection of layers. Role or function Give users access to the GIS layer or layers in a custom map viewer (e.g., IndianaMap or Google Earth) or in desktop GIS software (e.g., ArcMap) Types of REST Services that will be offered by IndianaMap WMS desktop GIS software, open source online map viewers KML for Google Earth and supporting open source platforms

Advanced features Caching Caching Definition Each layer (including basemaps) is pre drawn as tiles of imagery at predefined levels of detail and spatial reference Caching on IndianaMap Spatial reference: UTM, Zone 16, NAD83 Scales: Thirteen levels ranging from 1:2,500,000 to 1:500 1:500,000 1:250,000

Advanced features Caching Dramatic responsiveness Better server usage Improved scalability Function Cached Map Service Dynamic Map Service 1.5 seconds 4.0 seconds

Advanced features Caching Performance From ESRI White Paper, August 2009 Caching retains high performance, even with a large number of users

Advanced features Caching Task Related Performance From ESRI White Paper, August 2009 Even with caching, the performance of certain tasks degrades with more users

Advanced features Caching Caching IndianaMap We have chosen compact cache Bundled file format Each bundle contains 16,000 tiles Given 30M tiles per layer, then there are 1,875 bundles 240 layers = 7.2B tiles = 450M bundles Spatial reference: UTM, Zone 16, NAD83 Scales: Thirteen levels ranging from 1:2,500,000 to 1:500 Tile size: 512 x 512 pixels

Advanced features Caching The Challenges of Caching IndianaMap The problem Caching more than 240 layers Time required = 3 days per layer More than 2 years would be required to complete caching on a single machine The solution Cloud computing Partnering with University Information Technology Services (UITS) of I.U. High performance computing, utilizing multiple ArcGIS servers Only about 2 months will be required to cache more than 240 layers

Advanced features Caching The Challenges of Caching IndianaMap Size and number of tiles: Exploded versus compact ~ 30 GB per cached layer Basemaps and imagery are considerably larger ~ 300 GB

Advanced features Caching Caching and spatial references Web Mercator versus UTM

Advanced features summary The advanced features: can be used in many different applications and viewers underpins the functionality of IndianaMap Viewer (R3) makes the IndianaMap Viewer (R3) easier for users to build custom maps You need a runway before you take off ~Anonymous
