From: Deepsea Dawn Date: November 28, 2007 10:27:33 AM PST To: ppgis@lists.oregonstate.edu Subject: Today's PPGIS session Greetings PPGISers, I hope you enjoyed what I thought was another very interesting lecture this morning.... A reminder that our final WUN lecture will be held next Wednesday, Dec. 5th, at 8:00 a.m. See you then! And in the meantime, GO BEAVS!!!!! Dawn [8:07 AM] Robin (ICOSS): I've had the pleasure of hearing David Mark talk about semantics and landscape of native populations (North Am, Australia) on a number of occasions- do you see any overlap between such work and the PPGIS perspective? [8:07 AM] Kimberly Pettit: thank you dave u [8:07 AM] Robin (ICOSS): p.s. David is at Buffalo (USA) [8:11 AM] Dave: Can the analysis of literature, or physical measures of response to scenery help quantify these 'unquantifiable' things? [8:13 AM] UWa: The risk literature has been researching values, objectives, criteria and their relationships for a few years. Has any of that been useful in your research? [8:14 AM] Robin (ICOSS): (with apologies to the chair)- for those who have just joined it will take a couple of minutes for the slides to load for some of you. [8:18 AM] Robin (ICOSS): What about species that need fire to regenerate and the impact on 'natural' landscapes? see http://en.wikipedia.org/wiki/Serotiny [8:18 AM] UWa: This suggests that "meaning" is scale dependent? as well as dependent on many qualities of the world? [8:19 AM] Robin (ICOSS): I think scale is important here- contrasting with some of the work David M. has done- interesting [8:21 AM] Dave: we've been here before -- do maps clarify or confuse the 'public'? [8:22 AM] Jason: It depends on who "public" is, and whether or not individuals are spatially challenged [8:22 AM] "Deepsea Dawn": It seems that those with traditional *ecological* knowledge are very good at understanding traditonal maps? [8:22 AM] York:SIL: is the use of maps selective in terms of who participates? [8:22 AM] Robin (ICOSS): worth mentioning http://www.geog.le.ac.uk/splint/ in passing [8:22 AM] UWa: What if what is valued is not on the map, but in the world...just not mapped? Is that possible? [8:22 AM] David D: In your Spoleto position paper you wrote that "we, as academics, tend to credit the public with more knowledge, greater rationality and enthusiasm for decision making than we perhaps ought." Was this true in this case study? [8:23 AM] York:SIL: Is there a way of enabling participation without face to face meetings? [8:24 AM] Kimberly Pettit: How likely is it that people are selecting the intended location on a map? In my experience few people know how to select a defined location on a map. [8:25 AM] UWa: meeting without face to face: see www.letsimprovetransportation.org - the experiment is done [8:25 AM] York:SIL: Thanks [8:26 AM] Dave: I worry greatly about the representtaive of this type of sampling [8:26 AM] York:SIL: Would use of aerial photos / satellite imagery be better than conventional maps? [8:27 AM] York:SIL: what range of jobs do the participants do? How were they chosen? [8:28 AM] Robin (ICOSS): Do you standardise spraying to have a base measure between participants or topics- e.g. "spray this box to show how much you like chocolate, driving, maths etc." and use a l Likert scale to rate this too?? Could be useful for comparison between people and topics [8:29 AM] Richard: I don't think it does therefore it is difficult to compare one persons level or degree of intenisty with another. [8:30 AM] Robin (ICOSS): could be fun (and/or meaningless!) to explore [8:31 AM] Robin (ICOSS): Scale of spraying may also relate to the scale of the issue/topic of interest- larger geographical features may have a different signal to small important areas? [8:32 AM] UWa: With an overlay of these areas what sort of conflicts of use (perhaps value) arise? [8:36 AM] Robin (ICOSS): agree about neighbourhoods issue- had a meeting about this this afternoon [8:38 AM] UWa: In the mean time, why not try to answer your three questions [8:40 AM] Rina: How did you decide on the key participants and stakeholders? [8:49 AM] Kimberly Pettit: very interesting and applicable quote in my experience [8:50 AM] Jim: I guess you could start an interview with one or two more factual questions asking people to identify specific locations on the map to assess their spatial literacy... [8:51 AM] Robin (ICOSS): Jim, what sorts of places do you think we should pick- sometimes things are very fuzzy, any thoughts? [8:52 AM] Jason: Spatial literacy seems to be a pretty important variable. Perhaps assessing stakeholders' spatial literacy should be a key component of formalizing PPGIS methodologies ? [8:52 AM] UWa: Diversity of perspectives is perhaps as practically meaningful as a 1st step in comparison to representativeness. Representative of what one asks? [8:52 AM] Robin (ICOSS): Very true Tim (et al.) [8:52 AM] Jim: I've seen some work published asking young children to navigate from home to school by drawing on aerial photos - that would test out the basics of map-reading, but not fuzzier concepts ----------- Dawn Wright | Professor | Department of Geosciences Oregon State University | Corvallis, OR 97331-5506 http://dusk.geo.orst.edu | 541-737-1229 phone | 541-737-1200 fax
