1. The 2000 Decennial Census School District Project: Using Census Data for the School District Mapping System **** Development and Implementation Tai A. Phan Tai_Phan@ed.gov 202-502-7431 DCSDLIST@inet.ed.gov

2. 2000 Decennial Census data 1999-2000 SD boundaries CCD and other NCES data ArcIMS Spatial Server ArcIMS Application Server ArcIMS Application Server Connectors ArcIMS Management (Admin, Authors,..) JAVA TEXT HTML NCES Server ArcSDE Architecture

3. Teams: NCES Staff Synectics for Management Decisions Inc. Unisys Corp. ESRI Experts Data: PL94-171 redistricting data from 2000 decennial census 1999-2000 school district boundary files from TIGER/line files 2000 decennial census long form sample data (384,000 households) 1999-2000 Common Core of Data Resources

4. Geographic Information System Computers are cheaper and faster GIS software is easier to use and geographical data are available Analyze data visually so they can be easily understood Presentation tool Query data on the fly Data display and analysis capabilities Create maps and download data using your Web browser Easy access to data with your standard Web browser Integrate local and Internet data Highly scalable server architecture Features

5. Using the Internet Resources Expand number of data users Cooperation between agencies in the government and between private sector and government Timeliness Flexibility Access to a wealth of geographic and census data Using ArcIMS and ArcSDE Requires some minor customization Integrated application capabilities Leading technology Can be upgraded and maintained one year from now, and 10 years into the future Can be applied to local data integration Centralized database Support for Windows and Unix Industry Standards Uses TCP/IP protocol Products

6. Text viewer: Profiles of school district - comparison between 2 school districts Download data file - by state, county, or by school district Standard viewer: Easy to use Map and profile of school district/county/state Thematic mapping of pre-selected tables/items Download school district boundary files by state/county/school district Standard GIS functions: pan, zoom, identify, select, query Java viewers: Thematic mapping Map and profile of school district/county/state Standard GIS functions Extended GIS functions: map note, local data, WWW data, selected by circle, line, multiple points Note: Requires downloading of Java and ArcIms Viewers (10MB). Primarily for GIS users. The School District Mapping System

7. The School District Mapping System - Data Availability Timeliness and Currency Cost Effectiveness/Funding: Efficiency of data file size Accessibility Security Flexibility Content Cooperation

8. The School District Mapping System - GIS ArcIMS and ArcSDE Content Process/implementation RDBMS install and configuration Database design 1-geodatabase 2-storage 3-feature of system Admin tasks server- power, memory, resource requirements Performance Tuning 1-bandwidth requirements 2-internets and intranets Backup and Recovery Cooperation Inter-government Private Companies

9. ArcIMS* Multi-tier system : Browser to present maps and data Applications / Logic Data Source Browser - Java, HTML, and Text viewers Applications / Logic Web Server - Windows NT, communicates with Application server by connectors using Active X ArcIMS Application Server - Handles incoming requests Tracks mapping services from Spatial server Can talk to multiple servers ArcIMS Active X Connectors - Using Windows NT solution Spatial Server - Holds Created Images, renders maps on server Query - handling data queries Support Geocode Extract - send files (shape and data) to data users Data Access Manager Support ArcSDE layers, shapefiles, ArcSDE coverages Map services - Image - requested maps are generated as JPG, or GIF Feature - requested data is in bundled and streamed and cached on the client allow additional client side capabilities Data Storage - shape files, ArcSDE, images

10. ArcSDE* A channel for storing, managing spatial data in relational database management system RDBMS - leverage scalable structure Integrated Data - cartographic and tabular can be stored together and retrieved Geodatabase Technology Multi-user access Support spatial and non-spatial queries Perform GIS operation on data ArcSDE server is an application server for GIS clients - direct access to RDBMS Minimizes network traffic with server data filtering Back up and security TCP/IP access ArcSDE Data Model ID, geometry, address - Spatial indexes for support spatial data queries Virtually all formats can be imported * - ESRI Technical Notes The School District Mapping System - GIS ArcIMS and ArcSDE

11. Summary, Recommendations, and Conclusions Implementation phases based on the available budget and resources No one vendor offers all of the services required Ensure to give continuous input into designing specifications before the work begins and throughout the project Don’t micro-manage and avoid big change orders Ask for input from others (consultants, experts) but don’t expect a free lunch Make sure that data would be compatible with the GIS software Make sure NCES existing hardware system is compatible and can be upgraded as needs evolve System is scalable and easily updateable to meet NCES data users need KEEP IT SIMPLE Training and Workshops MIS NCES Summer Data Conference ??
