SxSW Musings and Where the World Is

Virtual Earth, ehm, bing - Wed, 03/17/2010 - 05:02

As I’m writing this I’m sitting on a plane from Austin heading to the Microsoft MIX conference in Las Vegas. I have 12 of the 16 new foursquare badges in hand, a brain full of ideas for what’s to come, and a brazen interpretation of the SXSW conference. I figured I’d share a few thoughts.

Augmenting Maps with Reality. For those of you who came to my Bing panel, thank you. And, of course, a huge thanks to the panelists – Dennis Crowley (foursquare), Laura Diaz (NAVTEQ), Kellan Elliott-McCrea (Flickr) and Ryan Sarver (Twitter). I prefaced our panel with the idea that we would do no demos and have zero visuals and no presentations. The panel was a true panel with nothing but discussion. We discussed everything about how maps are created today, the data that is geo-tagged for usage with maps, how new types of data will shape the mapping world, how pictures and video will reinvent mapping and data visualization, integrating the historical aspects of mapping and shaping our real lives around location and the applications that leverage location contextually.

Location is happening now. I know, I’m totally skewed on this topic; however, if you think about it I’m really not. I’ve been working in location-based services for over 10 years and every year “is the year of location and mapping.” So, I’m actually kind of tired of hearing it. At SXSW, I was seeing it. Companies like foursquare and GoWalla were promoting their apps for checking into locations and sharing your position with friends. I’m a foursquare user and if you were in Austin, you were able to get an updated version of the application. I found myself using the foursquare application for things I’d yet to use it for:

A. Trends (Parties) - I was using foursquare for finding where the coolest parties were, at any given time. If I was at a party and it was getting lame, I would fire up foursquare and see which nearby venues had the most people checked in. Then, I would head that direction.

B. Search – I found myself using foursquare to find places to eat, drink or relax. I noticed a distinct behavioral change in myself because I wanted to acquire badges that entitled me to nothing more than bragging rights. So, I would use Foursquare to find places since I would get “credit” toward a badge if the venues were marked correctly.

C. Connecting – If I met someone – socially, professionally or otherwise – and I added them on foursquare, I was using foursquare to contact them via text, phone, Facebook or email. Since all of these settings are built into foursquare (and usually exposed) it made it quite easy to connect with people I had just met. This means, no more business cards!

Life is good. Applications like Facebook have been predominant in finding out what’s going on and sharing your life experiences through your status or photo and video uploads. Now, Facebook has become a one-stop destination where everyone is publishing information about what they’re doing in real time. If I want to Tweet about the band I’m watching, I fire up TweetDeck and post it to my Facebook (and Twitter accounts). If I want to commit to an event, I fire up Hot Potato and share my event information where I’ll be. If I want to tell people where I am, a badge I’ve achieved or a mayorship I’ve self-coronated, I can share all of that with Facebook and Twitter automatically. The key is that at the end of the day, it’s about having fun, living life and sharing your life with the people who want to be in your life but perhaps can’t. So, reading streams of data coming through Facebook is the closest thing.

Search war continues quietly. You may think the search war is between Bing and Google. Maybe it is. At Bing we’ve been winning over users by creating great experiences and helping users make decisions rather providing search results to every web site under the sun that has some heuristic relevance to the respective keywords. On top of that, Bing has innovated in areas such as Image Search, Visual Search and my favorite Bing Maps. How does this war wage on? In my opinion, it comes do to applications who are collecting massive amounts of user data. Many applications are about collecting information about places, people, events, etc. I downloaded a new application called Double Dutch. It’s about creating reviews about places. Similar to Yelp, I suppose, but with a location focus versus a business focus. Double Dutch (if they can do it right) is supposed to filter content in a way that makes location the center so you can find places that fit your needs more readily. Flook is one of my favorite applications. Flook allows you to take photos, geotag them, categorize them and add contextual information. All of this information is being fed into a few different popular destination sites like Facebook, Twitter and MySpace so they have instant access to them and have quietly snuck into a position that makes Facebook (for example) a top referring site for information. In fact, Bing and Google are both ingesting information from Facebook and Twitter to ensure they have great experiences in search.

Mobile has happened. For years I’d heard about how mobile phones were going to take down the PC market and change how we do everything. Not. Mobile is definitely here. If you’re not on it, you are missing out on some really great stuff. Everything I listed about is based on mobile scenarios. I was able to operate entirely with just my phone while at SXSW. The SXSW show even had a mobile application that let me peruse the event schedule. I saw so many people face-down in their mobile devices – texting friends to share information, trying to find the next good party, checking email, updating Facebook, Tweeting pictures – I mean you name it and people were doing it on their phones. All that being said, it doesn’t mean the PC market is dead. Not even close. It just means we as a society have a found a new way to communicate. A new way to share our lives with people. I wouldn’t write this blog post on my phone – I’d go insane! However, there are some really great use cases for mobile that make life fun! And, while we’re not working on our PCs, we’re having fun on our mobile devices.

SXSW was certainly the most unique show I’d been to (Maker Faire a close second), adding film and music to the mix. And, The City of Austin does a great job putting the venue together. So, a quick shout out and thanks to the people of Austin for making my time there so enjoyable.

I’m the mayor of this blog post.

GPS Log Analysis Uncovers Millions In NYC Taxi Overcharges

slash geo - Mon, 03/15/2010 - 12:42
Slashdot runs a story named GPS Log Analysis Uncovers Millions In NYC Taxi Overcharges. Their summary: "The NY Times reports that New York City's Taxi and Limousine Commission is using GPS data collected in every cab to review millions of trips in New York City over the past 26 months and has discovered a huge number in which out-of-city rates, twice the rate charged for rides in the five boroughs, were improperly charged. The drivers' scheme, the commission says, involved 1.8 million rides and cost passengers an average of $4 to $5 extra per trip when drivers flipped switches on their meters that kicked in the higher rates, costing New York City riders a total of $8.3 million. Cab drivers are supposed to charge the higher rate only when they cross the border between New York City and Nassau or Westchester. 'We have not seen anything quite this pervasive,' said Matthew W. Daus, the taxi and limousine commissioner. 'It's very disturbing.' The taxi industry vigorously challenged the city's findings, saying it was unimaginable that such a pervasive problem could be the result of deliberate fraud. The commission says that 75% out of the city's 48,000 drivers had applied the higher rate at least once. Officials hope to roll out a short-term fix in two or three weeks in which an alert will appear on the backseat monitor when a cabbie activates the out-of-town rate." What I find funny, in the previous related stories below, is that in 2007, we discussed one named 'New York Taxi Drivers To Strike Over GPS', and before in 2005, a previous one named 'NYC Cabbies Say No to onboard GPS ', no wonder...

Friday Geonews: More Open Source Geocoders, Geolocation Comes to Facebook, RADARSAT-C News and more

slash geo - Fri, 03/12/2010 - 21:22
Here's your weekly dose of geonews in batch mode.

On the FOSS4G and open data front, there's a followup entry reviewing more open source geocoders (initial story). via the OGD blog I found an interesting entry on the failures of Edmonton and Vancouver open data efforts: "[...] two minor mistakes that are preventing the Edmontorcouver opendata initiative from being a tremendous success [...] 1. They expected a new community to build itself. 2. They wrote their own license." GeoServer new supports ImagePyramid imports. There's also a long article about creating interactive charts with Geopublisher 1.4. There's also a short entry on displaying two different graticules in QGIS. Here's a site that let's you overlay OpenStreetMap data transparently On Google/Yahoo Maps.

In the everything-else category, Slashdot discussed a story named about a new phone to track employees movements and a discussion on augmented reality. Here's an entry named Geotag Photos with an Android Phone and Any Digital Camera. Via O'Reilly, here's an entry on Twitter's location policy. You can also embed Bing Maps Twitter Maps on your website. Geolocation is also coming to Facebook next month. In fact, MapQuest has a new feature to share MapQuest maps woth Facebook friends. The Canadian RADARSAT Constellation got confirmed funding in the recently announced federal budget. Using GPS sensors, it seems the Chilean earthquake moved the City of Conception 10 feet to the west. In addition to the Google geonews shared this morning, here's Fredericton, Canada in 3D and Bloemfontein, Port Elizabeth and Pretoria in South Africa and Mulhouse in France also in 3D.

Virtual Earth, ehm, bing - Fri, 03/12/2010 - 16:26

We've just released an update to the Twitter Maps application in the Bing Maps Application Gallery. NOW, you can embed our Twitter Maps functionality into your own web site. This means you can be cool by having a Bing Map on your web site, blog, favorite social networking site with the Tweets you care about. And, WOW, it’s super easy. 

 

 

You can do this in four easy steps:

  1. Select the map location either fixed (centered on a specific point) or anywhere (moves the map as the Tweets come in).
  2. Specify the dimensions of your map (height and width).
  3. Add search filters. These will be carried into the embed form if you’ve specified them to filter only tweets that meet your search criteria.
  4. Copy/paste HTML into your web page.

Google Geonews: Biking Directions in Google Maps, New StreetView Imagery, and more

slash geo - Fri, 03/12/2010 - 14:47
A lot of recent major Google geonews lately. Google made the announcement of the addition of biking directions in Google Maps: "This route avoids hills (phew!) and puts me on the Burke-Gilman trail for most of the journey. When I need to get off the trail to cross town, biking directions makes sure to keep me on bike-friendly roads and avoid some of the city's busiest intersections. The time estimate for the route is based on a complex set of variables accounting for the type of road, terrain and turns over the course of my ride. [...] When Map Maker is available in the U.S., all riders will be able to directly contribute their local knowledge about trails, bike lanes and suggested routes.". On the Google Lat Long blog, you'll get more information regarding those biking directions: "[...] I can lift the curtain and explain the many factors and variables that we've had to take into account to put this whole feature together [...]". Obviously, offered bike routes are not perfect and will improve over time.

There's an official entry on the major StreetView imagery update. Mapperz shows a map where we learn almost all of U.K. is now available in StreetView. You can now also edit places directly in StreetView. Also adding to integration, there's a new 'Edit this place' capability in Google Maps. There's also Barcelona now in 3D in Google Earth. The GEB offers a nice wrap-up entry named playing games in Google Earth.

Vodafone's Wayfinder Closes Shop

slash geo - Fri, 03/12/2010 - 11:20
Found on Engadget. It demonstrates just how deadly Google can be to the core business of other companies. From their article : "Back in January 2009, as Vodafone was preparing to close a £20 million ($30 million) deal to buy Swedish mapmaker Wayfinder, it was seen as a bold move from a carrier intent on entering the apparently lucrative market for location based services. Fast forward to the present day -- past the bit where free Google Maps Navigation destroyed TomTom and Garmin share prices, and past the introduction of free turn-by-turn navigation to Nokia's Ovi Maps -- and you'll find Wayfinder gently sobbing into a handkerchief as it permanently closes up its doors. Vodafone's Anna Cloke gives us the reason for it with devastating concision:"We could not charge for something that others gave away for free.""

Digitizing and Geocoding Old Maps?

slash geo - Thu, 03/11/2010 - 13:54
Slashdot discusses a story named Digitizing and Geocoding Old Maps? Their summary: "I have quite a few old maps (several hundreds; 100+ years old, some are already damaged – so time is not on my side). What I want to do is to digitize them and to apply geo-coordinates to them so I can use them as overlays for openstreetmap data or such. Obviously I cannot put those maps onto my €80 scanner and go. Some of them are really large (1.5m x 1.5m roughly, I believe) and they need to be treated with great care because the paper is partly damaged. So firstly I need a method or service provider that can do the digitizing without damaging them. Secondly I need a hint what the best method is to apply geo coordinates to those maps then. The maps are old and landscape and places have changed, it maybe difficult to identify exact spots. So: are there any experiences or tips I could use?" See also the replies on the site.

Introducing the new Google Geocoding Web Service

slash geo - Tue, 03/09/2010 - 13:58
After yesterday's review of open source geocoders, Google just announced the introduction of the new Google Geocoding Web Service. Improvements, from the announcement: "* A flatter response format for address components that is easier to parse. * The ability to tag an address component with multiple types. * Both full names and abbreviations for countries and states. * Differentiation between rooftop and interpolated geocoder results. * Both the bounding box and recommended viewport for each result. [...] The Geocoding Web Service is intended to enable precaching of geocoder results that you know your application will need in future. For example, if your application displays property listings, you can geocode the address of each property, cache the results on your server, and serve these locations to your API application. This ensures that your application does not need to geocode the address of a property every time it is viewed by a user." See also related stories below.

Review of Open Source Geocoders

The linear thiking blog offers a short review of open source geocoders. From the entry: "All of the engines implement parsing and matching logic purely in code. None of them provide a declarative description language to allow easy modification of parsing, standardization, and matching rules. [...] In all the projects the parser design appears to be fairly ad-hoc and poorly documented. This situation doesn't inspire confidence that it would be possible to modify the parser to support a different address model, or to handle particular kinds of input errors."

Bing Maps SXSW Panel Announced

Virtual Earth, ehm, bing - Mon, 03/08/2010 - 18:47

About 6 weeks ago I asked the Bing Maps Product Management team about our presence at SXSW. A couple weeks later they gave me a panel. Then, they asked me to proctor it. Oh, and populate it. Hmm, this was a bit more than I was expecting to take on, but always up for a challenge I ran with it and now I’m proud to announce my panel for SXSW jam-packed with location all-stars. My panel is on Sunday, March 14 @ 9:30 AM. Here’s the scoop:

 

Augmenting Maps with Reality

Remember when the utility of an online map consisted of directions and gawking at satellite imagery?  With the recent tide of location-based apps, maps is rapidly emerging as the gateway to socially exploring the world around us.  But that’s not all.   In this future focused discussion, we’ll explore the rise of maps as a social platform and it’s potential beyond.    

Check out this lineup:

Dennis Crowley – foursquare - CEO & Co-Founder

 

 

Laura Diaz – NAVTEQ - Senior Manager, Partner & Developer Program

 

 

Kellan Elliott-McCrea – Flickr - Architect

 

 

Ryan Sarver – Twitter – Director, Twitter Platform

 

 

Proctor: Chris Pendleton – Microsoft – Bing Maps Technical Evangelist

 

I tend to think of myself as a one-man wolf pack. But when I met Ryan, I knew he was one of my own. And my wolf pack... it grew by one. So there... there were two of us in the wolf pack... I was alone first in the pack, and then Ryan joined in later. And six months ago, when I met Dennis and Laura, I thought, "Wait a second, could it be?" And now I know for sure, I just added two more wolves to my wolf pack. And now, finally, Kellan joined the wolf pack. Five of us wolves, running around the desert together, in Austin, looking for music with maps. So tonight, I make a toast!

I hope to see you at my panel…or, somewhere in the streets of Austin.

The ArcGIS API For JavaScript 1.6 Now Available. And ESRI also announced their new World Topographic base map (screenshots included).

On the FOSS4G front, here's how to create contour lines in QGIS. There's also a new Humanitarian OpenStreetMap Team (HOT) mailing list.

In other news, several geoblogs mentioned that Platial is turning off their services. APB offers an entry named GIS Used to Help Decrease Stroke, Heart Disease, and Cardiovascular Risk 25%. There's also an entry about large shapefiles on small screens using a drawable spatial index. Engadget does a head-to-head comparison of three GPS smartphone navigation systems: Google Navigation, Ovi Maps, and VZ Navigator. TMR also points to the testing of the SPOT Satellite GPS Messenger.

In the maps category, via Mapperz, I learned about ProtectedPlanet, the latest initiative of the World Database on Protected Areas. Here's a named Which Burger Chains Dominate the U.S. Landscape? Here's another map, linking the affordability of housing and transportation in the U.S.
