To talk about those, we have Sarah Nusser from the Department of Statistics at Iowa State. NUSSER: I'm going to talk today about digital geospatial data and survey data collection.

They come in a lot of different formats, and they have a lot of issues about them that really affect how we set up our survey data collection systems. And I'll probably only have time to talk a little about the cognitive aspects; there's a whole other set of problems that have to do with computing infrastructure, because these data are very voluminous and require some adaptability in how you work with them.

A1SO7 because we're mobile, we're starting to come into this dynamic component where we might have a GPS moving along in a map, and we get to the first data collection we want to do, which might be capturing a route to get back out of a convoluted neighborhood or for the next field rep to be using. Finally, in data collection this is really tough, and there's a lot more to be done on this side it's usually a very focused activity at a specific location.

" I'm going to talk a little bit about this, and one thing to lceep in mind is that there's a lot of variability in how people perceive spatial information, so we want to bring that back into creating settings and interfaces and tools that allow us to get back to our principle of repeatability in data collection. So the basic goals for using digital geospatial data in field data collection tare]

An interesting aspect, it turns out, is that our anxiety over performing spatial tasks varies very widely across people and sometimes within people. So if you've been lost, and you've gotten sort of befuddled, and you have trouble placing yourself on the map, this is lcind of your mental state decreasing your spatial ability, and that's important when you get lost out in the field and are trying to find your way to your sample site.

From page 203... ...
What you're doing is aligning three different reference frames: one is yourself, another is the reality around you, and the third is the representation of that reality, the map. If these things are not aligned, you have more mental rotation to go through.

The staff did that; they generally accepted the order and they always accepted the route. So you're left with dealing with a map and route listing interface; you can adjust the size of these, you can adjust the font size, you can lceep or hide features lily hotels and restaurants.

Would it provide those additional cues that would get them over the hump in using maps? And then there's a whole number of things that GPS software car' do not the one we were using in terms of recording routes, capturing coordinates, and using voice cues in navigation.

And how milch dissonance is there when yolk have this in your vision field and you're trying to do other things? Where am I on time?

There's also some literature that says that females think differently from males spatially; there's also in the literature a convergence in how they think, so I think that my personal theory is just a little bit lilac the Web: as time goes on, and socialization becomes different, then people will tend to be thinking in the same way. MARICO SIAN: I didn't quite understand how you could differentiate preferences for north-up versus head-up maps .

NUSSER: I'll just go over this quickly; I threw this in because we had this comp sci community, and in the survey world we tend to have a very rigid structure in the way we set up our data collection systems. So I'll just throw these ideas out here.

We have the spatial strategy component that I tallied about earlier, and then physical aspects having to do with how quickly you're travelling, whether you're travelling by car or foot, what you're doing do you have your hands and eyes free, and then disabilities that really are no different from these physical settings, just an additional cause for having limitations. In the field computing environment, we're sort of thinking about the traditional things: what is the screen size, what is its resolution, is it color, do you have a little device that doesn't have much storage or processing ability, and how much does storage decline over time as you collect information, communications aspects and interface modalities.

COHEN: Handheld devices are being trumpeted for use in data collection for the 2010 census. Do yol1 see the need for different types of devices inside the blue line versus outside the blue line?
