Tageo supports Google Earth

After posting about the global place directory Tageo three weeks ago, I emailed them and suggested they add a link to an automatically generated KML placemark for each location in their database. They said they were looking into it. Today, I happened by there and noticed that now you get exactly that.

Suddenly, Tageo rocks as an ancillary to Google Earth: 2,667,417 coordinate pairs to go look up, a very forgiving search function (if it doesn’t get a direct hit, it makes clever suggestions) and a linked list of nearby places. I’m adding it to Ogle Earth’s list of essential tools.

Katrina prompts experimental data delivery in Google Earth

Google Earth Community sysop PenguinOpus has announced that the “Katrina” layer in Google Maps over New Orleans is now available as an experimental network link in Google Earth.

It’s a view-based refresh network link, which fetches the Digital Globe data 2 seconds after your motion over New Orleans stops. What’s innovative here is that the data consists of tiles, just as in Maps, and is delivered via a PHP script, with URL http://dev.keyhole.com/katrina/dg/tileserver.php

I’d love to know what that PHP does:-) It looks like it accesses the exact same tiles as Google Maps does, depending on what level you are zoomed in, no doubt determined by the bounding box of your view, which the PHP script receives. As those tiles are all just small jpegs, the script would need to decide how many to fetch and how to arrange them.

Indeed, if you look at what the network link delivers, it is a list of overlays, each containing one tile, and each one being independently adjustable on/off and for transparency. Very nifty.

Do read the whole thread. It contains interesting feedback.

PS. This of course means that the Google Earth team, should it want to, could now deliver the original Google Map tiles to Google Earth via such a network link/server solution. Unlike with Google Maps, however, Google Earth is able to drape these tiles over height information, which would definitely be worth a look just to see if it results in something cool and/or useful.

[Update 2005-09-05: This network link is now also available from Google Earth’s main Katrina page.]

Google Earth up to 3.0.0548 Beta

It’s not showing up via my update functionality in Google Earth, but if you download a fresh copy from the home page now you’ll get version 3.0.0548 Beta, up from 3.0.0529 Beta. Running the installer asks you if you want to update.

So far, updates have shown up in increments of x.x.01, so this one looks to be a little irregular. The release notes also appear to be identical, and I can’t actually spot any difference between the two versions. (Was the Dining feature there in Layers previously?) (Alerted here.]

Google updates Katrina info for Google Earth (again)

Google Earth’s home page now has 2 major KMZ updates for downloading: One links to a collection of 3228 post-Hurricane Katrina images from the National Oceanic and Atmospheric Administration (NOAA) created “through some serious efforts by NASA, Carnegie Mellon University, and Google.” The other is a collection of all the overlays and placemarks submitted to Google Earth Community over the past 8 days related to Katrina.

This whole is an impressive example of collaboration and self-organization. Thanks to everyone involved.

What’s interesting from a social software perspective is that it is still Google Maps that provides the best means for dynamically updated user-contributed data, however. Witness the Katrina Information Map (with more possibly showing up on Google Maps Mania) that lets visitors add placemarks onto a map of Louisiana with messages or information. Google Earth’s “API” is still far too limited to let that quality and ease of interaction happen. Until it does, the application remains a one-way street when it comes to live updated data — easy to consume, but hard to contribute. This is probably the biggest obstacle left to Google Earth’s becoming the next generation browser.

[Update 09:21 UTC: One further thought: It also appears to be a lot easier to add an ad hoc “emergency” layer to Google Maps than it is to Google Earth. A feature request for Google Earth, then: A permanent “Emergency” or “Special” item in the the Layers directory that can be automatically populated with this kind of data, which we currently download manually.]

WMS in Google Earth: Whose job is it?

Digital Earth Weblog’s final installment of its Google Earth Wishlist is out. Andrew Hallam would like public WMS services to provide more complete and more user friendly metadata for mainstream users, and also have them provide KML files for accessing the data using Google Earth.

But above all he would like Google Earth to have native support for WMS. Given that WMS is not currently aimed at the layman user I’d expect such a feature to be reserved for the Plus version.

NWS should adopt KML

Nagoyan the Earthhopper has been keeping an eye on super typhoon Nabi, which is tracking for Okinawa and possibly thereafter the Koreas, ETA September 7.

Over on Google Maps Mania, he links to Digital Typhoon, a site maintained by Japan’s National Institute of Informatics that provides typhoon Information for Google Earth.

National weather agencies really need to start offering KML overlays and tracking data as a default. We can make our own, but many more will use these tools if they are “official” and seamless to download. The Tulsa forecasting office of the US National Weather Service led the way, but not without getting into trouble for it (just a little). Yet if the USGS can publish in KML, there should be no reason why the NWS can’t follow suit.

[Update 13:01 UTC: Nagoyan’s Flikr page with a shot of Nabi.]
