Nearc2011 web state of art presentation
- 1. GIS Web-sites: Current trends,future directions and the state-of-the-art Version 8 Michael Terner Executive Vice President
- 2. Overview • History of this talk • Issues of the day • Mobile devices as a driver • HTML5 vs. other immersive technologies • Impact of cloud-based hosting • Capitalizing on cloud-based map/tile services • Customization vs. templates ©2011 Applied Geographics, Inc. Slide 2
- 3. History of thisPresentation: the web is constantly changing 8th variation since 2000 ©2011 Applied Geographics, Inc. Slide 3
- 4. Mobile devices asa driver A plethora of new devices and more ubiquitous broadband ©2011 Applied Geographics, Inc. Slide 4
- 5. People want mapson their mobile devices But how do you get them there? ©2011 Applied Geographics, Inc. Slide 5
- 6. HTML5 vs. otherimmersive technologies • Flash and Silverlight are waning • Plug-ins are less desirable – Notably on mobile ©2011 Applied Geographics, Inc. Slide 6
- 7. Recent announcements onFlash/Silverlight ©2011 Applied Geographics, Inc. Slide 7
- 8. HTML5 vs. otherimmersive technologies • What is HTML5? • W3C standard • Puts onus on browser makers to ensure there is compatibility • Avoids need for 3rd party plug-ins – Like Flash & Sliverlight ©2011 Applied Geographics, Inc. Slide 8
- 9. Some characteristics ofHTML5 http://www.w3.org/html/logo/ ©2011 Applied Geographics, Inc. Slide 9
- 10. HTML5 allows foradaptive/responsive design Can run in full browser mode on a PC, or on a phone ©2011 Applied Geographics, Inc. Slide 10
- 11. “Phone apps” vs“Phone web apps” • Pure phone, e.g., “iPhone app” – Takes better advantage of phone hardware • Camera, GPS, accelerometer, etc. – But, requires standardization on a single phone • Or, building a different app for each phone ©2011 Applied Geographics, Inc. Slide 11
- 12. “Phone apps” vs“Phone web apps” • Phone-based web-app – Relies on the phone’s browser app – Web pages, HTML5, JavaScript • Can be optimized for small screens • “Adaptive design” – Good access to GPS; camera not yet supported (but coming) – Examples of “minified web pages” http://Maps.google.com http://Touch.Facebook.com ©2011 Applied Geographics, Inc. Slide 12
- 13. Impact of cloud-basedhosting • You don’t need a data center to host web apps – Why buy, when you can rent? – Not just hardware, but also: • Bandwidth • Air conditioning • Can scale applications by adding “virtual hardware” on demand – Of course, software licensing may not be so seamless Image from Paul Ramsay, used with permission. ©2011 Applied Geographics, Inc. Slide 13
- 14. When do youneed to scale? What is a launch spike? Data from WA’s broadband site launch • WA State Pales to FCC’s 1st day of 500,000 visits & 9,000 requests/sec; But still a planning factor. • Governor makes an announcement • Press release is issued • Newspaper runs a story ©2011 Applied Geographics, Inc. Slide 14
- 15. Cloud based hosting Things to know • Need to understand virtual machines and offerings – IaaS vs. PaaS vs. SaaS • Need to understand the cost model – Fixed costs of virtual hardware ($’s/hour) – Data storage cost • $.14 /GB/Mo = $1,860 /TB/Yr – Usage fees for data access • $.01 /10,000 file accesses means 1,750,000 files = $1.75 • Pushing data onto the cloud can be a bottleneck – How thick is your pipe? – Can send physical drives ©2011 Applied Geographics, Inc. Slide 15
- 16. Capitalizing on cloud-based map/tile services • Use of other people’s map services – Often national or global in scope – Often for free • Esri has them • Bing, MapQuest, Google • OpenStreetMap (OSM) ©2011 Applied Geographics, Inc. Slide 16
- 17. Esri’s tile menu ©2011Applied Geographics, Inc. Slide 17
- 18. Documentation to findthe tiles ©2011 Applied Geographics, Inc. Slide 18
- 19. Things to understandabout cloud-based map tiles/services • Some come with restrictions – Sites must be publicly available – Tiles must be delivered through our API • The rules can change, and costs may be added – Google’s recent announcement: it will cost you money if >25,000 connections/day • Most tiles come in the Web Mercator projection – Cannot reproject tiles on the fly – Performance penalty for reprojecting dynamic services on the fly ©2011 Applied Geographics, Inc. Slide 19
- 20. Customization vs. templates •Templates provide easier, out-of-the box capability – Both Esri & partners may take this approach – Can be delivered at lowest cost • Write once; deploy many • There are tradeoffs in being more generic – Many applications will all look the same – Can be difficult to customize – Can be difficult to integrate into a workflow – Integrate with a business system – Excellence vs. mediocre ©2011 Applied Geographics, Inc. Slide 20
- 21. Customization vs. templates • There is room for both approaches • Some templates better than others • Creativity and innovation matter • Focused, workflow-based sites • Site reflects what you want/need – Your site is a public representation of your organization and can be a good place to invest ©2011 Applied Geographics, Inc. Slide 21
- 22. Conclusions • Web technologies are constantly moving • Standards (W3C, OGC) can be important hedges against technology change • Know your options & make informed choices ©2011 Applied Geographics, Inc. Slide 22
