3. In the table below, give an example of a Layered Information System and explain why you think it is a Layered Information System:
| My Name | An example of a Layered Information System |
Why do I think this is an Layered Information System? |
|---|---|---|
| anne | text arc.com | This takes a text (shakespeare) and as the line is shown as a whole on the bottom of the page, the visual stream of light moves across the screen mapping its path on a aggregated page with all the words of the play listed with the most repeated words featured more visibly. It was mesmerizing to watch and try to imagine the usefulness to education. Perhaps this is a way to identify themes or to identify the words that are stressed and another tool of analysing text. It could be classified as layered because the journey of the single line is layered on the aggregation of words from the text. I see this as a tool for scholars but can't see too much use for secondary students. |
| Peggy | frappr | I think this is a layered information system because it connects/displays users real world location to a virtual world map and then allows them to post information about themselves at that location as well as receive messages from others. |
| Alyssa | trendsmap | It's bringing together more than one data source that wouldn't naturally be linked together and putting it on a map. Making it interactable adds a nice bonus to explore the data. |
| Dominika | GPS | A layered infromation system brings together various segregated data sources into one centralized view in order to provide an new perspective on a set of information. A GPS provides the user with the ability to personlize the information they want to know about the location they are going to. For example showcasing where there is food and gas along the highway that is being travelled on. It seems simple but before you would just have a paper map and wait for a blue road sign, now you have the ability to bring up the information at the touch of a finger on a single screen to plan your next stop. |
| Loredana | cabspotting.org | The project captures patterns of movement within the city of San Francisco by tracking taxi cab routes. A living, changing geographical map is created from the data, offering different layers of information related to "economic, social and cultural trends that are otherwise invisible". |
| Nisha | Google Earth | It brings together the layers of map, search, photographs so that when zoomed in to a particular address you can see some amazing details topographical details |
| Alejandro | GIS | GIS (geographic information system) is a type of software that can layer various types of data onto a map. This can include census driven statistics, locations of infrastructures, locations of green spaces in a city, etc.. Moreover, it allows users to share any mapped data by indexing it geographically. GIS software is used by city planners, urban designers, engineers, architects and policy makers and provides a common system for the sharing and layering of information. |
| Nathan | Ecotect | This is not on the examples list. This program is geared towards architects and building engineers to simulate a building and its materials where multiple test can be applied to the building material and configuration to give results of environmental and energy performances. The simulation results can be analyzed with further computation or stored for future refernce into the model. Selecting parts of the building read you different information. Essentially, specific material information is specified into a component where it can be laid out onto a structure and made useful when compared and read together with the rest of the building. |

| Courtney | Guelph.ca Transit | Not sure if this is an example but the City of Guelph has teamed up with Google maps and has made people able to plan their trip online using the map. Also they have a system where you can check when the next bus is coming by texting the number of your bus stop and through the buses GPS system you get a text back that tells you when the bus is coming. At least I think that is how it works. But again I have no idea if this is an example nor could I really figure out where to find the examples! |
| Denise | Nextbus.com |
Although somewhat limited, NextBus uses a GPS tracker to tell you when the next streetcar is coming, the service overlays GIS tracking web and mobile tech. http://www.nextbus.com/predictor/stopSelector.jsp?a=ttc\\ |

I looked at a number of them and found them quite interesting. It is new to me so I need to sit a bit with it to see how these possibilities would relate to my field. However, I thought the Grass site was very interesting as an example of a community of specialists who have taken GIS, combined it with a lot of other web functionalities and created a site that looks like it would be very useful within a specific discipline; that is flexible and allows for changing knowledge; that actively seeks new user input and is open source. In fact, it looks like a great example of knowledge building being done by an international group of participants in a way that could not have been done in the past.

Community leaders, tourists, citizens, business start-ups and more are all interested in the "vibe" of a certain neighborhood. Some of this is being studied through Twitter posts and what people might be "buzzing" about, but this approach takes it to another level by capturing the physiological response someone may be having to a certain location. Note that there is more than the physical lat-long coordinate that plays a role into someone's emotional response, but this method still provides an interesting data set. I also like the greater self-awareness that this project is seeking from participants.

For new commuters if you are not sure where to go or when the next bus is coming, you just need to punch in your location and Google will tell you what the best option is. This a nice application instead of having to look at a city map and try to overlay that with the TTC map to see where the stops actually are. I also really like the feature on Google Maps that when you click a subway stop on the map the subway routes appear overtop of the map providing you with a visual as to whether or not the specific route is the right one to take.

I wondered, for example, if during the piloting of a curriculum, different instructors' movements through the curriculum document could be tracked in such a way as to suggest directions for curriculum revisions. The data collected might reveal changes to organization of the course content, or the content itself. A question that arises, however, is how much data would need to be collected to reveal enough of a pattern?

For example if you want to start a restaurant business in a particular area, you could turn on the layer for dining and all the restaurants in the area will come up giving you the areas that are open for opportunities.

It's especially good for travellers because it allows them to access transit info for any city, not just Toronto. I'm also interested in layered information projects that help people engage creatively and inquisitively with their environments. One good example in the wiki is the work of the Spatial Information Design Lab. This project takes location data from 'tagged' images on Getty Images and places them on a map. By using solely pictures from fashion or art events, the map they have created reveals the hot spots of the city or the "Geography of Buzz" as the authors refer to it. Twitter, Google Earth and Flickr have the capacity for users to create mash-ups.

Firstly however, the American crime mapping sites are much more interactive, current, and user friendly, however I felt it important to have a Canadian context. The use of LIS (specifically geographical software mashed with statistics) allows the user to search their neighbourhood (or others) to view crime statistics. It also allows police services to compile crime rates specific to a community to see if there are patterns occuring. From a real estate perspective, it is interesting information but I can see it abused in the sense of using these stats to affect housing rates and property tax values. Also, statistics could become biased, what is being reported, who is being victimized, etc but users would need to look at this information with a critical lens and not accept it as face value.

I think it would be brilliant to be able to keep track of all your students and see where they went and how much time they spent at each section. Plus it would make it easier for the teacher to not have to count all the time.
