The first release of GeoExt (v0.5) have been released. GeoExt is a JavaScript toolkit that allows the user interface features of Ext JS to be easily used with the popular OpenLayers client mapping toolkit. There are some examples on the GeoExt documentation pages. Although these examples are very simple, they hint at the professional ("desktop-like") user interfaces that can be produced.
Further details can be found on the GeoExt Website. |

On Tuesday, the ArcGIS Online sharing application service has been opened up for a public beta: 6/30/09–Have you ever wanted to share some of your great maps with
the rest of the world? Or maybe just easily share some of your work
with a colleague? Well, the new ArcGIS Online sharing application, now open for public beta access, can be used as a system for sharing,
finding and using GIS content across the Web. With ArcGIS Online, you
can upload maps, register online map services, create and save Web maps
as items for others to share, and discover and use maps published by
ESRI and other ESRI users. You can organize and control access to the
maps you share by making them public or private, and you can create and
join groups.
Better sharing of geographic information is enabled in part via new
technology that allows layers referencing feature or raster data to be
packaged into a single "layer package", comprised of both the layer
cartography and data. These layer packages can be shared with other
users via files, e-mail, or the new ArcGIS Online sharing capability.
The new ArcGIS Online sharing services are powered by a full REST API. The announcement and further information can be found here.

Although it isn't very clear on the main list of new features, thanks to Mapperz for the heads-up that today's release of Firefox v3.5 includes a new geo-location feature. This is an optional new feature that lets a website query the browser's geographic location. The user has to explicitly confirm that this it is okay to share the information. Location information is currently derived from wireless hotspot information and ISP location information. In a test this morning, this produced a 22km error circle for my location, but managed to find the correct half of Irving, Texas - if not quite the correct zipcode. |

Had enough of the "Web2.0" moniker? Tim O'Reilly, who is often
credited with its invention, has a new paradigm, "Web Squared".
O'Reilly asks if the web is becoming more intelligent. His thesis is
that it is becoming more of a platform for collective action, and that
location information is a key integration of this new "intelligent"
web. Web applications will be increasingly driven by mobile sensors
connected to cloud databases. Mobile devices will have a sophisticated
sense of place, and be able to tap into this cloud information, perhaps
even providing augmented reality services.
These ideas were put forward in a webinar as a promotional item for
the Fall Web 2.0 Summit. Here is a YouTube recording of the webinar:

The Associated Press are reporting that Dutch police arrested twin brothers on suspicion of robbery after the victim spotted a picture of them on Google's Street View. The victim, a 14 year old boy, reported to Dutch police last September that he had been robbed of €165 and his cell phone after two men dragged him off his bicycle in Groningen. As he was unable to identify the attackers, investigations did not proceed very far. That was until the boy found himself on Street View and two men who believed to be the attackers. The location was correct as well. Faces are blurred in the Netherlands' version of Street View, so the police requested the unblurred images from Google. Google complied, and the Dutch police reportedly recognized one of the alleged attackers.
Dutch police report that the use of Street View as being unique for them. The full AP report can be found on the CBS News site.
The Google Street View cameras are catching quite a few things which you would think might cause the car to stop. As well as imminent thefts, it has managed to capture house fires (with no fire engines in attendance) and photographed deer being run over by the Google car. |
