PUBLIC MARKS with tags data & gps

These are images of map generated entirely from GPS logs gathered by various versions of the Geoloqi sample application for iPhone and Android for the past 3.5 years. Once gathered, the data was run through a custom script that projects the GPS logs onto a 2D image plane. There is a little bit of logic to smooth out the lines and remove some (but not all) GPS noise.

Often we do not know if there is a pattern before collecting enough data for revealing the pattern.

Not having a pattern (or more exactly having an anti-pattern) can also be encouraging. For example, the data can help me to control and remove as much as possible the routine in my actions.

The low cost of getting data (minimal action or no action) with contextualization of these data with different types of shapes, graphs, even poetry makes them interesting. If our effort is too high, we stop doing it.

On a more personal note, I really hate sharing these “stories-data” without my initial consent. All these services are like an invisible person in the room listening my conversation with these data. I like GPS (location broadcasting information system) because it is anonymous. I don’t like cellphone towers (identified localization system). They offer the same service, location, but the nature of collecting data is completely different.

knowing that the cinema is empty might attract people who wants to have empty rooms. The business case is possible too.

About being ubiquitous, there are two types of things. Accessible data on things, accessible data on people, I love the first one, I'm very worried about the second one.

I like GPS, because it is a (low quality) broadcast location grid system. It doesn't locate you, you locate yourself on a grid.

On the opposite, cellphone towers location systems are tied to an id (mobile phone contracts), it identifies your location. Very bad.

I wish cellphone towers where only creating a grid of geolocation.

Elevation is a free, open source route visualizer that renders personal GPS data in 3D space, built in Processing by Dave Shea.

These new interfaces enable developers to do nearly everything that you can do at http://blockchalk.com. It’s now possible to build client applications, mash-ups, and other tools based on BlockChalk geolocation data and services.

You can read the full API documentation here: BlockChalk API v0.6

So what does this mean? It means that BlockChalk is now more than just a nifty GPS app for your iPhone. It’s an open platform for storing and accessing user-generated content within a geographic context.

What makes the BlockChalk platform unique?

* It’s dead simple. There are no badges, medals, points, unicorns, pirates, or other viral gaming craziness. BlockChalk is about locations and the messages people leave there, that’s it.

Wile working with the GPS track data of the UrbanDiary project, in connection with the series of interviews I am conducting, I suddenly recognized the different shapes and patterns that are being produced by the participants. Really funny shapes and forms, but always with a number of strong fix points. The shape is determined by a number of factors such as the spatial relationship of destinations, the distances traveled, the amount of travel and the intensity of repetition. The first point, relationship of destinations makes for the overall shape and the last point, the intensity of repetition makes for the character of the shape.

The images are all generated from participants that have a track record of two month and are the same scale.

gpsd is a service daemon that monitors one or more GPSes attached to a host computer through serial or USB ports, making all data on the location/course/velocity of the sensors available to be queried on TCP port 2947 of the host computer.

We all now what a map is, its a diagram that tries to represent the real world on a flat piece of paper.if you understand something then you can control it, if you can control it then you own it.The methods of interacting with data have changed, but those producing it haven’t. if they create any new information with reference to the OS maps, like recording the location of every public toilet, then that data is classified as “derived data”. This derived data effectively cannot be shared with anyone who isn’t also licensing data from the OS. Essentially, it means that nearly every government dataset with any kind of location information is under lock and key. OpenStreetMap. If you want truly free data, that you can edit, share and do whatever you want with then pick up a GPS unit and start mapping.
