1. REGIONAL ONLINE GEOSPATIAL SERVICES FOR THE HOUSTON- GALVESTON REGION Brooks Andrews Houston-Galveston Area Council Chief GIS Analyst
2. DISCUSSION TOPICS  Background on the Houston-Galveston Area Council (H-GAC)  ArcGIS Server  Server Architecture  Publishing Scenarios  Caching Published Services  Streaming Published Services  ArcGIS Online (AGO)  Server and Web Architecture  H-GAC AGO Basics  AGO Web Maps and Web Apps  Empowering the Non-GIS User  Questions and Helpful Links
3. H-GAC BACKGROUND  Regional planning organization (Council of Governments)  13 county service area  Works with local governments to address needs of region  H-GAC Program Areas:  Transportation Planning  Community/Urban Planning  Environmental Planning  Socio-Economic Modeling  Area Agency On Aging  Cooperative Purchasing  Workforce Solutions  GIS Services/9-1-1 GIS Services
4. SDE Databases (NTDB07) NTArcGIS04 ArcGIS Server (Production) 8-Cores NTArcGIS04Dev ArcGIS Server (Staging) 4-Cores N A S Internal Network ARCGIS SERVER ARCHITECTURE  Two ArcGIS Server system  4 Core ArcGIS Server (Staging)  8 Core ArcGIS Server (Production)  Authorized Data Stores  Server Data Folder  Department SDEs  Local disk storage on both servers for data overflow  Separate storage for cached services
5. PUBLISHING SCENARIOS  Publishing a service with SDE data  Data source is from a department SDE  Publish using ArcCatalog Publisher connection  Department SDEs setup as valid data stores (no data copied to server system directory)  Publishing a service with FGDB data  Data source is from a FGDB loaded to server data folder  Publish using ArcCatalog Publisher connection  Server data folders are setup as valid data stores (no data copied to server system directory)  These scenarios can be used on both Production and Staging servers only by authorized publishers at H-GAC  Department GIS leads are given a publisher account to both servers
6. CACHING PUBLISHED SERVICES  Both servers (production and staging) allow for caching  Both servers use separate cache folders to store caches; ArcGIS Server does not support shared cache folders from separate sites  Currently have close to 2TB of storage for cache folders; can expand  Can build a cache on staging server, then release onto production server (e.g. QA/QC workflow) Staging Server Production Server Build Cache  Export Cache  Publish  Import Cache
7. STREAMING PUBLISHED SERVICES  Users (internal and public) have ability to stream published services directly into desktop GIS  Publicly streamed services require no login or approved credentials to access  Securely streamed services (H-GAC Aerial Imagery, STAR*Map, etc.) requires users to submit a request form for access  Services can also be consumed by web-based GIS applications using service URLs located in our REST Directory (https://gis.h- gac.com/arcgis/rest/services)  Detailed instructions found on our website (http://www.h-gac.com/rds/gis-data/gis-rest- directory-services.aspx)
8. SDE Databases (NTDB07) NTArcGIS04 ArcGIS Server (Production) 8-Cores NTArcGIS04Dev ArcGIS Server (Staging) 4-Cores N A S Internal Network ARCGIS SERVER ARCHITECTURE WITH ARCGIS ONLINE (AGO) ArcGIS Online Web Server/ Web Adaptor DMZ https://h-gac.maps.arcgis.com REST Service REST Service
9. H-GAC AGO BASICS  Sharing Content  Not Shared- Default  Shared with Group- Members of group can view  H-GAC- All H-GAC affiliated users can view  Public- All can view, even visitors without a login  Groups  We can create broad groups (departments) or specific groups (projects)  The Featured Content group displays items shared on the homepage as a showcase gallery  Our H-GAC AGO site is not federated with either ArcGIS Server, therefore service REST URLs cataloged in AGO do not consume credits
10. AGO WEB MAPS AND WEB APPS  We use our published service REST URLs as catalog entries in AGO; they then become content (mostly web layers) in AGO  Web Layers  Web Maps  Web Apps  Web App templates are easy to use and easy to understand  http://h-gac.maps.arcgis.com/home/index.html Web Map Web App
11. EMPOWERING THE NON-GIS USER  Non-Traditional GIS users (no desktop GIS experience) can learn and use AGO with ease  Users can create their own mash up web maps with various web layers than can become web apps from templates  Apps are deployable on most major mobile devices and morph to specific device skin  Empowers the non- traditional GIS users and frees up time spent on paper map requests
