In search of the point

What’s the point of having a national mapping agency when even semi-public agencies like our Umweltbundesamt (environmental agency) are doing data dissemination based on Google Maps and Geonames? [via joesonic]

Speaking of paleogeography is in that case certainly appropriate: neogeography makes the national mapping agency look like an endangered species. Even though I never really liked the terms and heated discussions about paleo- vs. neogeography. To me, paleogeography sounds way too negative for what it actually does. Paleogeography still provides a major part of the backend and a lot of necessary knowledge for the so called Geoweb. Period.

While neogeography is the cool thing. It’s fresh, slick, easy to use and attracts a lot of bright people outside the geography area who are doing amazing things with geographic information. Personally I see myself somewhere in between and try to get the best out of both.

Obviously some paleo organizations, like our national mapping agency is for instance, should look slightly to the left and to the right of their very straight path. It seems they are still serving the geo market of the last century. Their traditional products, like the topographic and cadastral maps, are certainly great and important works, but in the meantime they have to face the fact that the geo market has a little changed in the last couple of years.

Believe it or not, even in Austria there are map based businesses growing. Companies or start-ups who arrange their business models around easy and affordable access to local geographic information. Most of them depend on the goodwill of global players like Google or Microsoft. The EC usually is very quick when it comes to express concerns about monopolies of those companies and threaten them with law suits. I think, as for the geo market, the European mapping agencies have enough resources – in terms of geo data, infrastructure and knowledge – to throw into the game. They are powerful enough to compete with the big players, provide alternative map services and eventually support local economies. If they only wanted to.

Besides, the above mentioned example shows very well the benefits of neogeography for the public sector and that there is growing demand for such technologies.

So, again, where is the point of keeping a huge tax funded public body when it rejects to move on, serve current public needs, support local economies and public wealth?

Ed Parson Google doorEd Parsons, former Ordnance Survey CTO, joined Google as Geospatial Technologist for EMEA (Europe, Middle East and Africa). A brilliant move and Ed is surely a tremendous asset to Google.

It’s important for Google to have someone with his visions on board and bring traditional geospatial industry and neogeography closer together.

Congratulations!

Reference systems

MicroformatsAt yesterday’s Web Monday, hosted by Metalab, I attended an interesting presentation about microformats (given by Eric). Among other things the open microformat standard includes a “geo” element to define geographic locations.

As Alex yesterday mentioned, the documents, as well as the documents referred to, lack of declaring a reference system. It’s quite obvious, and has been already discussed in the geo microformat BOF, that the coordinates enclosed by the “geo” tag are based on WGS84.

How come that WGS84 didn’t make it into the document then? I think an “open standard specification” must not allow any room for misinterpretations and therefore should include the declaration of the applied geographic reference system in some section.

…it works in Google Maps, so it seems to be right…

Ouch.

Why is defining a reference system important?

Once you leave Google Maps behind and try to visualize your geographic information in other mapping applications, such as national mapping services based on national reference systems others than WGS84 for instance, you should tell those applications about the framework you used to identify your locations. Otherwise you’ll run into troubles regarding the accuracy of your locations.

Austria is a small country but the national reference system includes 3 different prime meridians. In order to achieve satisfying mapping results you’ll always choose the closest meridian to your mapping area. Without the information which meridian was used for data collection for instance, you’ll end up having at least 3 options where your locations could be.

No serious web developer would ever write an HTML-document without a valid Document Type Declaration. It’s quite similar in geodesy with geographic data and reference systems. Would be great to see neogeographers fulfill minimum geodesy requirements. Geography is for some time around now and things like reference systems have turned out to be very useful.

Geoblogger.eu clean-up

In order to avoid post duplicates I cleaned up geoblogger.eu and removed all feeds which are already aggregated by planet geospatial. So geoblogger.eu should now be a nice add-on to planet geospatial, for people interested in mainly non-english geoblogs.

E like Easter and .EU

As you may have noticed, or not, there is a new top level domain available: .eu.

I got caught by the landrush two weeks ago and registered 2 new domains too.

If I didn’t mess up with my redirects you should see the first one above in your browser’s URL bar: spanring.eu. It’ll be my new main domain name for this site. During Easter holidays I found the time to change my server configurations and update DNS, etc. If you have any bookmark or subscription please change the URL to spanring.eu. Well, the old one, spanring.name, still works and will do so for at least another year. Probably even longer, because there is a good chance that I’ll keep this domain too.

The second domain I bought was geoblogger.eu:

geoblogger.eu is an aggregation of GIS, cartography or “neogeography” weblogs based in Europe or in any other way Europe related. The aim is not to exclude the rest of the world but to focus on the European scene and to give a general overview about people, organisations or topics of interest in this region. [more]

The main idea behind geoblogger.eu was quite simple: publish and share geo related parts of my reading list. Maybe somebody else finds this site and links useful or, even better, has some recommendations on further weblogs to include. If so, feel free to send an email to ask[at]geoblogger.eu.

I’m well aware about geobloggers.com, the former Flickr Google maps geotagging mashup, but geoblogger.eu just says in one word what this site should be about. If there is any problem in terms of registered name or something, please let me know.

The newsfeed on geoblogger.eu isn’t working properly. I’ll try to fix it within the next few days.

Sharing privacy

Lately I registered at Platial, a social networking platform that allows you to share places. It works quite similar to del.icio.us‘s bookmark sharing, Flickr‘s photo sharing or last.fm‘s music sharing. You can add every kind of place, you can tag them, comment, collect them in maps, publish maps where others can add still more places. You can do a lot of nice things with Platial. [Read more about Platial on Wired]

While exploring some maps and places people added, this marker came up in the recent places category:

SexOffender_Address_#1

Ok, hmmm, so what’s that supposed to mean. Well, I’m certainly not defending sexual offenders, but I doubt that a service like Platial is the right platform to list and pinpoint such citizens. How would I feel if I find a label saying “sexual offender” or “released murderer” floating over my or my neighbours address? There is no way to check this accusations or to find further information about it on Platial. Nor isn’t Platial designed to provide appropriate legal documents either. Such a label only makes room for several speculations, resulting in insecurity.

Platial is based on geographic information, enriched by personal experiences in order to enable social networking. The problem I see is that unlike other social networking platforms, Platial allows sharing others privacy. I can pinpoint my neighbours house and tag it with “tasteless architecture”. Primarily I would share my personal experience, but do I have the right to share my neighbours location too? Of course I could take a picture of my neighbours house, upload it to Flickr and tag it with “tasteless architecture”. But as long as I don’t add name and address nobody’s privacy would be violated. The photo description on Flickr, where I add name and address, would classify as additional information because Flickr is about photo sharing, not photo-description sharing. Furthermore, if my neighbour finds out about his house, address and my tag on Flickr he still could flag the photo as “may offend” and let the Flickr administration team know.

In del.icio.us I share my bookmarks, my favorite sites in the internet, something very abstract. I can’t share somebody else’s bookmarks. On last.fm the root of any social activity is sharing my taste of music. I can’t share the genres somebody else is listening to. It’s impossible and wouldn’t make sense.

In Platial the required information to enable social networking is the location. Combined with the single word “fraud” as place name this basic information can already do a lot of harm and heavily violate someone’s privacy. That’s the main difference between Platial and other social networking sites I think.

Platial is a great idea (hopefully it’ll be successful in Europe too, so far there are not many european Platial users) but something has to be done to prevent abuse and respect the privacy of people who don’t want to get involved.

Update #1:
Luistxo from Tagzania encounterd the very same problem: sex offenders of Detroit have been mapped by a user on Tagzania. [Read the post en español].
The first comment on that post is quite interesting. It points to Google Maps API Terms of Use where you’ll read:

You agree that when using the Service, You will not:
defame, abuse, harass, stalk, threaten or otherwise violate the legal rights (such as rights of privacy and publicity) of others

Says it all, or maybe not? Marking out some addresses and labeling them with the word “sex offender” isn’t violating any rights in Google’s eyes.
