I'm sorry I didn't put any examples of hyperGIS (flash), or technical blurb...
For comparison a hyperGIS (flash) solution http://hypergis.hinnerup.dk/construct.asp?id=h_master Here's a large collaborative solution, though only in Danish I'm afraid http://www.iform.dk/polopoly.jsp?d=1756&a=10447 The server converts several formats including GML to Well Known Binaries (WKB) >From there the data can be generated as .swf, in vector, raster or a combination of the two for use in Flash client applications. All attributes can be preserved in the generated objects, similar to SVG and used for client side interactivity, applications etc. Cheers Peter S. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Cameron Shorter Sent: 08 May 2007 08:28 To: [email protected] Subject: Re: [Geowanking] Examples of collaborative data collection apps? Ok, I better put in a plug for the AJAX case. Jennifer, I apologize for talking technology when you are probably more interested in the use case. Mapbuilder is a standards based, feature entry tool which allows users to collaboratively edit geographic features. It runs in a standard web browser without requiring users to install any plugins (like Flash). This has the advantage that users don't have any technical obstacles preventing them from getting involved. At the back end, you can run a Transactional Web Feature Service (WFS-T) like Geoserver connected to a geospatial database like PostGIS. (This is a fully Open Source, Standards compliant stack). There is an example at http://nightly.communitymapbuilder.org/mapbuilder/demo/wfs-t/index.html A while back, I wrote up a white paper on the subject. My work priorities changed after writing it and it has become a bit dated, but should give you some background. http://bikemap.openearth.com.au/ Peter Strømberg wrote: > Hi Jennifer > > Shameless plug, but we've created a Flash platform (hyperGIS) for just > such applications. > > Our biggest success to date is a portal for collecting running routes, > with several attributes attached and fully searchable.
