Google Map Maker Returns

mar 14-07-2015

You may recall that Google took down Map Maker blaming it on algorithms.

Certain offensive search terms were triggering unexpected maps results, typically because people had used the offensive term in online discussions of the place. This surfaced inappropriate results that users likely weren’t looking for.

Well Google has apparently figured out a plan to allow people to start editing the Google map data.

Map Maker will be reopened for editing in early August, and we’re looking for users to now have more influence over the outcome of edits in their specific countries. This means that edits on Map Maker will be increasingly made open for moderation by the community. While some edits will still require moderation by Google operators, our loyal users will recognize that this is a departure from how we have operated in the past where majority of your edits were reviewed by Google operators. This has been a request you’ve made for a very long time, and this change should, hopefully, come as good news.

Community editing, who knew? Google will be “selecting” mappers around the world to be “Regional Leads” on Map Maker. I’m not sure why anyone would want this title but I guess we’ll see soon enough what it entails. Edits have to be moderated before they are published to the map so the quick updates that happened before (and of course happen with OSM) won’t work for Google. I think though considering how things went last time, any change is good for Google.

SpatialTau v2.9 – Geodatabase vs geodatabase

mer 10-06-2015

SpatialTau is my weekly newsletter that goes out every Wednesday. The archive shows up in my blog a month after the newsletter is published. If you’d like to subscribe, please do so here.

What does the word “geodatabase” mean to you?  I’m sure most of you answer that it’s Esri’s proprietary spatial data format, either the classic Microsoft Access Personal Geodatabase or the newer folder based File Geodatabase.  But really it also applies to any spatial database, Esri or not.  Spatialite is a geodatabase.  PostGIS is a geodatabase. CouchDB is a geodatabase.  I could go on of course.  But when we talk about geodatabases we sometimes get our wires crossed.

Just last week I was talking with a client and they were using the word geodatabase to describe both File Geodatabases and PostGIS.  Internally they knew what they were talking about but I went back and forth between understanding what exactly we were discussing.  After a good laugh we talked about the concept of spatial databases abstractly and wondered if the word “geodatabase” was the right one to use.  When I search with the term “geodatabase” with Google, my first 3 results are Esri, and then we see a Wikipedia article on spatial database.  Google image search is littered with Esri examples of their Geodatabase with almost no other database being described.  You can see above I refer to Esri’s product at “Geodatabase” (big G) and the generic term as “geodatabase” (little G) but when we talk it is very hard to see the difference.

So what right?  Does it really matter?  I’ve gone over this the past week since my discussion with the client and I’m of the mindset that Esri “owns” the geodatabase term.  If you search my blog you’ll notice I’m pretty good about making sure I use “Geodatabase” and “geodatabase” correctly but honestly I don’t see why I should.  Saying “spatial database” is so much more descriptive than geodatabase and honestly more understtandable to non-GIS users.  I think in the bigger picture of Spatial IT, referring to something correctly generically matters.  I’m going to use Geodatabase (big G) to refer to Esri’s spatial formats and spatial database to describe spatial databases.  I think the clarification matters and defines the difference between a file format and an actual spatial database.  Heck I can even say a Geodatabase is a spatial database and sleep well all night.

SpatialTau v2.8 – Buying Your Own Mapping Company

mer 03-06-2015

deCarta has a soft spot for many of us. We saw them hit highs with Yahoo! and Google and then lows when they were dumped. Just 2 weeks ago I talked with Marc Prioleau about deCarta on my Hangout. Last night though the news hit that Uber was buying deCarta.

Uber, the popular ride-sharing startup, is acquiring the mapping and search startup deCarta for an unspecified amount, Mashable has learned.

The deal, which closes later this week, is for deCarta’s technology and talent. Founded in 1996, the San Jose startup provides a software platform that focuses on location-based features, including mapping, local search and turn-by-turn navigation.

So deCarta is now owned by Uber. Uber told Mashable:
“A lot of the functionality that makes the Uber app so reliable, affordable and seamless is based on mapping technologies,” an Uber spokesperson told Mashable. “With the acquisition of deCarta, we will continue to fine-tune our products and services that rely on maps –- for example UberPOOL, the way we compute ETAs, and others – and make the Uber experience even better for our users.”

Makes total sense right? The whole point we use Uber and similar services is because they get a car to us in a couple minutes. Marc Prioleau wrote up his thoughts on the acquisition and came to the conclusion there is much to like about deCarta for Uber. I personally think deCarta helps the backend of Uber improve. Marc’s totally right about that (read what he wrote, it’s worth it). But on the consumer side, the one you and I see when we use the Uber.app I still don’t think they’ll replace Google Maps with deCarta. Marc has a theory that they may want to have a different look to their maps than what Google and Apple have but I honestly think consumers hate change and having Google as the visualization makes perfect sense for Uber.

We’ve seen companies like Mapbox do custom tile sets for clients but these projects are the exception to the rule. On iOS and Android, Apple and Google control the maps and most developers just use what is given them by default. The backend system though, those that improve how Uber operates clearly will be given more support. That said, it isn’t like Uber fails to get their cars to their customers.

I have no idea what Uber uses today, it could be some Google based application, some custom code created by them or a consultant or maybe even Esri. But having more staff that understand maps completely will only assist Uber in improving their service. Clearly every little thing helps Uber compete against taxis and Lyft so it’s probably money well spent. That and deCarta gets a nice landing spot. Wins all around!
