GIS Application Development for the Internet: What you need and how to get started!
Fred Hejazi – Director of Geospatial Services, Avineon Inc.
Today’s Agenda
• Differences between desktop GIS and Web GIS
• Evolution and architecture of today’s Web GIS
• How the components work together
• Licensing models
• How to select the right technology (Example Project)
• Selection Process– External hosting allows for rapid start up (no need to purchase hardware) – Linux requires less hardware– Google maps is more appropriate for a public facing application– PostGRE is free and includes PostGIS if future GIS analysis functionality is required – PostGRE data is also supported natively by ArcGIS as a Query Layer– Use of Plugins is being phased out by most web developers in favor of Javascript
• Development time: 3 days, deployment cost: $40 per month12
Mapping
Database
Technology
Hosting
Future Direction
• Reduced costs• More applications by
“non-GIS” programmers• Open source data and software
– Openstreetmaps.org– Open layers ... and several others
• More “Apps” less “Maps”• Integration of mobile and sensor technology• Phase out of Silverlight and Flash based mapping• HTML 5
– Google switched about a month ago– Expect others to follow – Significantly improved performance– Cross platform support on mobile

Conclusion
• Try before you buy (or start development)Examples:
Google routing Max 10/23 way pointsArcGIS standard Max 10 way points – 50 with World server
• Multi-vendor solutions may work best– ESRI Routing & Google Street views
• GIS skills not as important as technology skills• Expect and plan for a more complex architecture• Test performance • Select consultants with broad experience
