Well it is nearly the end of the year, and I shall be hitting the road this weekend, so let me wish all our readers the best of wishes for the holiday season - Christmas, Hanukkah, and of course the New Year!

This has been a good first year for the GeoWebGuru website. We have a number of new articles lined up for January, including a couple of articles from Geospatial Training Services and a follow-up to our popular series on map projections with a  two-part article on Polar Projections.

As ever, we welcome your comments, thoughts for new articles, and even article submissions. Have you been involved in a neat online mapping project that you'd like to write about? If so, let us know!

 
MapQuest introduce 360 degree street view service PDF Print E-mail

Adena Schutzberg at Directions Mag All Points Blog has the news that MapQuest have introduced their own 'StreetView' service. The new service can be viewed on the main http://www.mapquest.com MapQuest website. MapQuest claim:

  • 3D Imagery: 360° horizontal and 160° vertical views of any given image within 360 View on MapQuest.com.
  • Side-by-side Imagery: The street map is positioned on side of the screen and 360 View on the other; this puts the location in perspective.
  • Simple Navigation: Easily move to a new location by moving the green arrow on the street map.


Once it has loaded it is fairly quick but this is probably due to the relatively low resolution of the images. Coverage is currently limited. For example in the Dallas Fort Worth area, only highways and a few major roads are covered. This contrasts with Google Maps which has had coverage of individual local urban streets for a few years now.

I initially had some trouble getting it started so I think the user interface could be a little bit more intuitive. Once you have the StreetView panel up, the green arrow is easily moved - as claimed.

 
UK Government to offer 'free' postcode data? PDF Print E-mail

The BBC are reporting that the UK Government are planning to offer UK postcode data for free from April 2010.

The dataset that will probably be 'freed' is the geographic coverage data for each postcode, and not the Royal Mail PAF dataset which links individual addresses to postcodes.  Exactly how the data will be offered and under what conditions are still being decided. So, in common with the recent Ordnance Survey announcement, we should probably wait until the data is actually released before deciding how big a step forward this actually is.

Streetside, Enhanced Bird's Eye, and Photosynth added to Bing Maps PDF Print E-mail

Earlier today, Microsoft launched a significant upgrade of their Bing Maps service with the addition of "Streetside™", "Enhanced" Bird's Eye, and Photosynth views. The main Bing Maps site ( http://www.bing.com/maps/explore/ ) has been moved from JavaScript AJAX to the Silverlight 3 control.

Microsoft have been gathering "Streetview" -like data for a few years, so it is of no surprise that some of it has been released in their main map interface. However, Streetside™ is quite a bit more sophisticated than rival street imagery products. At first glance it might look the same, but as soon as you start to navigate, you realise that Streetside represents a fully immersive 3d model. This appears to be "Photosynth applied to street imagery, and displayed using Silverlight Bing Maps 3d", although I have yet to see any official confirmation of this. Streetside coverage is currently limited to US cities only.

The enhanced Bird's Eye views switch to 3d building models for urban areas. Non-urban views now include 3d terrain models (eg. mountains).

Technically, the PhotoSynth additions do not not add anything new, but the interface is now native. Select "PhotoSynth" from the legend, icons will appear letting you "dive right in" to a Photosynth.

This all sounds great, and the user interface feels slicker with the new Silverlight 3 version. The only downside with the new version is that I found the controls were not as initially obvious as they used to be. I think this is a combination of design/colors, as well as the fact that they've changed and I was simply used to the old controls.

The full list of additions can be found on Chris Pendleton's blog, here.

A few months ago, Twitter let it be known that it was working on a geo-tagging API. It has allowed this semi-official announcement to create some buzz and hype, and some of us wondered when it would ever be released. The wait is over, and Twitter have announced that the geo-tagging API is now live for all users.

The announcement can be found here. Twitter have also published best practices such as opt-in and full disclosure.

In a few weeks, we shall be revisiting the API with a technical overview and how-to.
