Nétek, R: The Impact of the Implementation of HTML5 Elements into WebGIS Applications

  1. 1. Impact of implementation RIA & HTML5 elements for WebGIS application Rostislav NÉTEKThis presentation is co-financed by theEuropean Social Fund and the statebudget of the Czech Republic
  2. 2. WebGIS Maps: Analogue –> Digital -> Web The Internet platform provide more options and becoming very popular Additional information or data linked to the map background (text, attributes, tables, images, video, animation, hyperlink, etc) Visualizing only x Interaction First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  3. 3. Request/response Via http protocol Visualizing geographic data using a server application Server side x Client side Map server communicates with a web server and processing data according to requirements New action = New request = Whole process Not sufficient nowadays First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  4. 4. Rich Internet Application RIA The last trend in the publishing and working with geodata General concept, not concrete technology AJAX, Microsoft Silverlight, Openlaszlo, JavaFX, Adobe Flex Brings the tools, practices and conventions from desktop platform into interactive web applications Esthetical features  Independent requests, asynchronous generating part of the results First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  5. 5. RIA characteristics (+) Run in the Web browser (both online and offline) Combine properties from desktop applications into Web interface No installation process required Immediate feedback, refresh is not required Rich content (video, sound, animation, vectors, drag and drop, keyboard navigation, ...) Platform independent Faster processing of requests Rich user interface Focus on esthetical impression Easy distribution and start-up Mobile applications are fully supported and available Open source Wide possibility of customization First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  6. 6. RIA characteristics (-) First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  7. 7.  GIS Flex Runs in the same environment like Flash Flex is not Flash ! Allows to create highly interactive Web mapping applications Emphasis on desing Fully web application brings features from both desktop and robust server solutions First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  8. 8. VIRTUS & BOTANGIS projects Virtual lab to access certain information about Litovelské Pomoraví Regional Nature Conversation Area Basic characteristics, environment data, nature conservation and many other topics Tabular, textual, graphic, multimedia and spatial form Visualise and manage content of Botanical garden of Palacký University in Olomouc First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  9. 9. VIRTUS & BOTANGIS projects Esri Flex client ArcGIS Viewer for Flex (API) First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  10. 10.  HTML 4.0/4.1 HTML5 HTML specification by World Wide Web Consortium (W3C) Final specification approved by the end of 2014 New tags Enables multimedia playing directly in web browser Without Flash support <canvas> Bitmap drawing container - rendering graphs, game, graphics and other visual elements as well as maps First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  11. 11. First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  12. 12. HTML5 vs. RIA Visualization methods Technological aspects Management aspects First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  13. 13. Flex vs. HTML5: Visualisation methods (-) Complicated process of generating (+) Flash/Flex has focus on vector graphic by default (+) Support of 3D graphic (+) Drag and drop (+) Video: expansion by embed Flash/Flex = YouTube (+) Rounded borders, Transparency (-) Previous HTML incompatible specs like SVG, VML (+) HTML5 introduces the canvas element & WebGL (+) Support of 3D graphic (+) Drag and drop (++) Rounded borders, Transparency, jQuery effects, … (++) Video: HTML5 & tag <video> = native browser support First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  14. 14. Flex vs. HTML5: technological & management asp. Form: HTML5 adds many new input types Offline mode Caching Cloud computing support Plugins & Widgets Development, testing, compatibility (+++) HTML5 First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  15. 15. The aspect Standard solution Flex HTML5 Vector graphic No (natively) Yes Yes 3D graphic No Yes Yes Transparency Partially Yes YesRounded borders Partially Yes Yes jQuery effects Yes No (Flex) YesPlugins & widgets Partially Yes YesAdvanced editing No Yes Partially Cache Yes Yes YesCloud computing No Yes Yes support First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  16. 16. Summary Both Flex & HTML5 provide great features into WebGIS Similar/same features = depends on the aim of application HTML5 provides designing Flex gives better opportunity of management aspects By both: The application should be extended by additional functions, plugins & widgets, the content and framework should be edited “onscreen” Flex just exists, while HTML5 is still more specification than real implementation Flex is the best solution for interactive WebGIS application nowadays, but within some years HTML5 probably replace Flex First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  17. 17.  Thank you for your attention Q & A? Pamela Fox, Sydney 2009: Just use them both, and get the best of both worlds  First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
