Talk of Deloreans and TagClouds

As we got our demo working our next phase is to move onto actually making it do something.  So after some sessions with Chris and Karlyn, Petra and I went away and attempted to come up with something useful which would describe some of the processes and screens in a meaningful way.  After some furious white-boarding, scribbling, crossing out, revising and chatting we managed to get a fairly workable model and a clear set of tasks/functions.

I used balsamiq mockups to create some fairly loose demo screens, which is a great prototyping tool as it has iphone templates making it easy to frame everything in a mobile context.

Here are some of the results.  Describing the starting points and what happens when the user goes back in time

After talking about some of these things we started to discuss how to represent time as a navigation item in the system.  Petra and I had originally proposed the size of the marker being how far back or forward in time the object is located.  Allowing the user to shift between maps and map sets without having to fully understand the datasets available to them.  Karlyn and Chris expanded on this by looking at it a different way and using the title of the landmark as a kind of visual “Tag Cloud”, and perhaps using the number of comments a landmark gets to influence the size of the text - removing the time element but creating an interesting social/folksonmy element. This style also lends itself to using tagging etc to create different perspectives on the data.

One Small Step…

One small step for the Team. On Friday we managed to get our first image rendered locked to our position  - well in truth after a little bit of fiddling around, we got it.
This was done using Javascript to get the position and then a call to the map server and out came an image which was pretty close to where we were using an iPod Touch but it should work with most platforms that support the Javascript.

We are currently exploring some of the techniques and methods we can use to try and navigate within the map and the phyisical space.

Open Location Services

Its intersting to note that the geospatial community’s main standards promoting body , whilst having a suite of open location service interfaces, seems not be as dynamic in this areas as in some others. Is this because the market is so fractured or that mobile uptake has been lagging whilst vendors and hardware ctahcup?

Shadows from another place

This online art piece by Paula Levine is an interesting take on GPS the origin of  surveillance technologies.

“Shadows from another place” is a series of hypothetical mappings, web-based and site specific, that use Global Positioning Systems to imagine the impact of political or cultural changes that take place in one location, upon another. The projects reflect ‘turns of force’ where sites of dispute become the templates mapped onto other locations. The idea builds on our growing cartographic imaginations, attenuated and fostered by new technologies that are remapping our understandings of space and place, borders and boundaries.

The first in the series, “San Francisco <- > Baghdad,” responds to witnessing the US invasion of Baghdad on March, 2003 through radio, web, TV— and the spatial dissonance that emerged from that experience. Baghdad sites of the bombs and missiles from the first U.S. invasion are transposed onto San Francisco. Each shadowed Baghdad site in San Francisco is documented by photographs, maps and GPS coordinates, this last being the same technology used by the military to target original sites in Baghdad.

The implications of walking and immersing oneself in a historical context seems relevant here. The idea of taking on board more than just the sights that were originally around a place, but the way of life - good and bad.

Jen Southern - Running Stitch

I’m working on a new piece for FutureSonic with Jen that explores collaborative Mapping.

Features an iPhone app that is development. In the meantime read about running stitch…

Running Stitch is a 5m x 5m tapestry map, created live during the exhibition by charting the journeys of participants through the city.

Visitors to the exhibition took a GPS-enabled mobile phone to track their journeys through the city centre. These walks resulted in individual GPS ‘drawings’ of the visitor’s movements that were then projected live in the exhibition to disclose hidden aspects of the city. Each individual route was sewn, as it happened, into a hanging canvas to form an evolving tapestry that revealed a sense of place and interconnection.

I’ve always like the way that GPS trails lay down a sort of social history - a trace of human activity. Google maps show everything. Warts and all.

As Rogers traces his way around cities it develops highly peculiar models of each city.

Great War Digital

This is quite interesting but limited to a specific historical frame: The Great War 1914-1918.

It uses Windows Mobile and more specifically Memory Map to download specifc maps.
