HeyWhatsThat: The video and the mapplets

Michael Kosowsky, who’s behind HeyWhatsThat (the website for generating panoramas from digital elevation models that I gushed about a few months ago) was invited to give a Tech Talk at the Googleplex a month ago. Michael writes:

It’s the best summary I’ve got of what HeyWhatsThat is and how it got to be that way. If you aren’t inclined to watch the whole thing, I think the Andrew Wiles joke at the very beginning is pretty good.

Here is the Google Video:

What more news? This post pretty much write itself: Michael says:

Have just spent a few weeks doing what we call “refactoring,” which in this case means rewriting almost every single line of code with absolutely no change in functionality. Well, not quite; contours are now available at every zoom level at the main site and the Path Profiler (you used to have to zoom in fairly close to get the ‘Contours’ button to appear; now you can see contours while viewing the entire world) and profiles that traverse large portions of the globe will be drawn as quickly as short ones.

I’ve also created a pair of “Mapplets” for Google Maps: Elevation Contours and Path Profiler. To see what I’m talking about, start at

http://maps.google.com/preview

Hit “Add Content” on the left near the top. As of press time my mapplets haven’t appeared in their directory, so hit “Add by URL” and enter

http://www.heywhatsthat.com/contours.xml

and then

http://www.heywhatsthat.com/profiler.xml

Hit “Back to Google Maps” in the top left and you’re off.

The result is stunning, and really shows off the power of mapplets:

Picasa Web Albums georeferencing: How does it compare to Flickr, Panoramio?

In a continuing trend to have users add location metadata to content uploaded to Google servers (following YouTube), Google’s Picasa Web Albums has now gained the ability to let you georeference photos from inside the browser, using Google Maps. Here is the announcement on the Official Google Blog.

How does this newfound ability compare to the georeferencing via Google Earth available for a while now in the standalone version of Picasa (for Windows and Linux), or the georeferencing already available on Flickr and Google’s own Panoramio?

First, here is how it works in Picasa Web Albums (henceforth “PWA”): Everything is focused on simplicity. For any photo in your online account (1GB comes free), there is now an “Add location” link, which leads to an Ajax-ish Google Maps popup on the page itself that first forces you to search for a place and then lets you tweak the exact location.

Georeference a number of photos in an album, like this one of Stockholm photos I have laying around, and the album itself can be viewed on a page in a layout that looks remarkably much like Google My Maps, down to the “View in Google Earth” link — which gets many kudos for its seamless integration. From this page, you can perform further tweaks simply by dragging the photos on the map. It couldn’t be any easier.

Stockholm

But there is one significant omission when compared to all the other services: Upload a photo that already has coordinate data in its EXIF metadata, as I did here, and it is not automatically mapped — you still have to georeference it manually.

If instead you first import the same photo to the standalone Picasa application, it does recognize the EXIF coordinate data, and will show you its location if you choose the menu item “Tools > Geotag > View in Google Earth”. If you then sign on to PWA from within Picasa, and upload such a photo to PWA, as I did here, PWA does automatically georeference it. (This makes Picasa far more geo-savvy than Apple’s iPhoto, Aperture, or in fact any other standalone PC photo editing tool I am aware of.)

[Update 2007-06-29: There is a preference setting that turns on the use of EXIF location data in PWA, but it is off by default. For security reasons? Importing from standalone Picasa overrides this setting, however.

Unlike PWA, both Panoramio and Flickr use EXIF coordinate data [by default] during a browser-based upload, and will map the photos for you automatically: Here is the photo uploaded to Panoramio, and here it is uploaded to Flickr.

By the way, Panoramio’s georeferencing “tool” is almost identical to the one PWA has just gained. This leads to some interesting questions as to how/if these two services will be integrated. There is significant overlap between the two services, though Panoramio photos are almost entirely comprised of postcard-style landscape shots. One solution might be that in the future, if users georeference a photo in PWA, Google asks if it might be suitable for inclusion in the Google Earth layer of descriptive landscape shots. And as for visualization… I think PWA’s new My Maps look is the way forward.

The main advantage that both Panoramio and PWA have over Flickr is the seamlessness of their integration with Google Earth — it is just a link, as it should be. In Flickr, viewing in Google Earth still requires some hacking, though if Flickr’s Dan Catt has anything to do about it (and he does) there soon will be built-in KML links for Flickr images. Until then, Panoramio is the only service that both recognizes EXIF coordinate data upon upload AND outputs seamlessly to Google Earth, with the added ego-boosting bonus of finding your photos published to a default layer in Google Earth. [PWA can be made to use EXIF data via the settings.] (BTW, Panoramio yesterday announced that another 200,000 photos were added to the Google Earth default layer, bringing the total to 1.2 million.)

Google Earth Outreach redux

Frank at Google Earth Blog has a blow-by-blow account of the events at the announcement of the Google Earth Outreach project at the NYC Googleplex, Google’s Rebecca Moore has blogged it, and the 1-hour video is now out on YouTube:

YouTube? Wasn’t that supposed to be for <10-minute clips? Wasn’t Google Video supposed to be for longer pieces? This is a good example of Google in action as it integrates two very similar services it has ended up owning: Do a search for “Google Earth” at Google Video, and you get results from both Google Video and YouTube. The Google Earth Outreach Conference video posted by Google appears there too, but showing a YouTube URL. Click on it, and you get to see the YouTube page as a frame inside a Google Video page. Google Video appears to be in a process of being deprecated — for example, there is no option in Google Video to georeference videos, something which YouTube recently gained.

It will be interesting to see how/if Google integrates Picasa and Panoramio. Yahoo! solved a similar problem, having bought Flickr and owning Yahoo! Photos, by deciding to close Yahoo! Photos without automatically converting all photos to Flickr but instead by giving users a range of tools and options, including a conversion tool for Flickr (but not Picasa or Panoramio:-).

Dassault Systemes & Microsoft aim at Google 3D Warehouse

The other big news today: France’s Dassault Systemes launched 3DVIA, “a powerful platform for partners to deliver unique 3D experiences to all kinds of online communities in the consumer and professional arena” (press release), and then announced it is putting the underlying technology to work right away to build a competitor to Google’s 3D Warehouse, for Microsoft Virtual Earth 3D:

Combining Microsoft’s geolocalization technology with DS’s proven 3-D modeling and realistic visualization know-how, this [MSFT-DS] alliance will enable consumers to add an entirely new level of realism within Virtual Earth, providing an unrestricted freedom for creativity and innovation. (press release)

Explains Chairman and Chief Executive Bernard Charles to Reuters:

We want to do the 3D Flickr.

That’s nothing if not ambitious. And how is all the metadata going to be managed? By creating a new 3D XML specification and player, called, er, 3D XML. In the announcement from two weeks ago, 3D XML is called a “universal, lightweight XML-based format”.

Universal is good, so I headed over to 3DVIA to check out the 3D model of the iPhone. It turns out that the 3D XML player is Windows only, but luckily 3DVIA also supports the 3D Life Player, which works on the Mac. There is even some code to paste to show off 3D on any website, so let’s test it here:

For Macs:

For PCs:

(Does the Mac viewer make your browser unstable? Also, I wish I didn’t have to provide both viewing options manually.)

All in all, I’ve come away impressed — for example, it supports the importing of all manner of formats (though not SketchUp’s native format). There is much more that we’ll need to figure out — such as, how open and expandable is the metadata format, and will it meet Avi Bar-Ze’ev’s requirements/wishlist for a semantic 3D web? Avi from a year ago:

What we really need is a new language of object representation that encapsulates and preserves form and function, aesthetics, style, meaning, and behavior, all tightly coupled and never discarded in the “art pipeline” until the object is finally rendered on your screen.

This certainly looks like a step in that direction.

  • An ESRI ArcGIS Explorer crystal bowl gazing roundup:

    Good to see ESRI recognizes there are upsides to going multiplatform. Even in the business world, many graphics, advertising and news departments run Macs; they’ll choose the virtual globe that runs best for them, and that virtual globe gets all the PR perks.

  • Here’d be a cool KML layer, as reported by Amateur Photographer:

    An historic archive of 800,000 aerial photos of Britain has been bought for the nation, paving the way for the images to be enjoyed by the public.

    D-log had the idea first.

Google Earth Outreach

Google Earth Outreach was announced at the NY Googleplex today. Relevant links:

The press release.

Google Earth Outreach, the website, including a by-now really meaty showcase of existing layers, and in-depth case studies of how best-of-breed layers were made.

A Google Earth Outreach discussion group has been set up, but so far I think by far the most useful part of the site is the new tutorials page, where you can download ready-made KML templates for placemark descriptions and instructions for turning spreadsheets into KML. Another find is instructions for using JEdit, a text editor that can be made to validate KML as you type (and it runs on OS X). (The placemarks templates are going to be a fantastic timesaver.)

Are you a “public benefit, US-based non profit with current 501(c)(3) status”? Then you are eligible for a free Google Earth Pro license. (It is restricted to US-only non-profits, but Google “reserve the right to make some exceptions.” I think it’s because there is no recognized global authenticating body for non-profits. So let your reputation do the talking.)

In tandem with this announcement, there are new default layers in Google Earth from the Global Heritage Fund, EarthWatch and from TransFair USA (fair trade co-ops).

Search Engine Watch provides color from the event, as does AP and IDG News.

  • Thirteen minutes into the most recent BBC Television’s Click new-technology program, there is a 5-minute report on 3D mapping, with a focus on Graz-based Vexcel, which Microsoft bought to get hold of its aerial digital camera system for Virtual Earth’s cities. Read the related story, or just click on the Watch Now button to see the program. Interesting quote:

    Director of Microsoft Photogrammetry [and Vexcel founder] Dr. Franz Leberl says: “The aerial mapping field is one of the few domains where film was still relevant. In other areas film has long been documented to be dead, so I think with this camera we are contributing also to doing away with film in the aerial mapping.

  • Youtube video of the TED presentation by Stephen Lawler, general manager of Microsoft Virtual Earth. Blog istartedsomething picks out the highlights, including “cute view”. I especially like the part at the end of the video where he blends bird-eye view imagery with the 3D map. Worth a look.

  • Those of you lucky enough to live in the promised land (as in, chosen by Apple for the launch of the iPhone), here is a KML file of all AT&T stores where you will be able to get one on June 29, in addition to Apple stores.
  • Antony Loewenstein says access to Google Earth’s servers is blocked in Iran. That would make Iran and Morocco the only two countries where such a blockage is in effect.
  • Plazes, a European web service that lets you share connections between events, people and places, now does KML.
  • Andrew Turner at High Earth Orbit

    writes a completely sensible and clear precis on how exactly KML and GeoRSS could coexist. Still, if KML is to HTML as GeoRSS is to RSS, then what I really want is GeoCSS.

  • A bit late to mention here, but very very cool: In addition to having GPS, a 5 megapixel camera, wireless communication abilities, a huge memory and an open operating system, the Nokia N95 is very light. Which makes it the perfect choice to be programmed for imagery acquisition from atop a remote-controlled plane. Pict’Earth does it again, with live positioning in Google Earth. Not surprisingly, Valery Hronusov was instrumental to the improvement over the previous, heavier solution.
