Following examples should show what is possible with Flex, and how do Geoweb applications in Flex look like.

  • Homelocator (http://www.asfusion.com/apps/homelocator/) Home Locator is an intuitive real estate searching application. It lets users search by area by clicking on a US map and then filter the results by price, number of bedrooms, bathrooms and other relevant criteria. For each property, detailed information is shown and actual location is plotted on a map, all in one screen. Users can see pictures for a property, helping them determine whether or not they want to visit the property. They can also save properties as favorites to be reviewed at a later time and can let other people see their favorite list. As a bonus, it also includes an administration to edit properties.
  • GIS Portal Aalen (http://www.gisserver.de/aalen/start.html) Aalen is a German town which has implemented their GIS Protal competely in Flex. It has all major function you would expect from a City WebGIS portal.
  • ArcWeb Explorer (http://www2.arcwebservices.com/v2006/solutions/awx.jsp) ArcWeb Explorer is a Web application that demonstrates browser-based map rendering. The result is improved speed and performance, greater control over the map appearance, and desktop-like functionality over the Internet. ArcWeb Explorer also demonstrates what you can develop with the ArcWeb Explorer JavaScript API. In addition to mapping streets, data, and imagery, ArcWeb Explorer exposes other ArcWeb Services functionality through various easy-to-use widgets. For example, you can use ArcWeb Explorer to quickly find locations, create driving routes, and generate demographic reports.

Note: For running all these apps you need intalled Adobe Flash Player.

If you know other Flex based Geoapplications you are welcome to post a comment.

SVG - is there a future in the Geoweb?

SVG (scalable vector graphics) is a recommendation of the W3C and used for rendering vector graphics. It was predicted that SVG is the future in the visualisation of geospatial vector data over the internet. Adobe announced that with Jannuary 2009 they will discontinue the support of their SVG Viewer plug-in (see here the official announcement). According to this Silverlight will most likely become the new Intergraph preferred standard for rendering vector graphics. (see reference entry).

Silverlight is a promising technology and the possibilities are huge. but I see some problems with this:

  • Microsoft and Cross Platform
  • Market share of Silverlight is currently near 0
  • Strong competitor with Flash and Adobe’s Flex technology

Furthermore there is the open question: Does SVG need a repacement? SVG is nearly a standard and a World Wide Web Consortium (W3C) recommendation which integrates with other W3C standards such as the DOM and XSL. I think browsers can or will nately represent SVG and there will not be a need for a plug-in.
