| Stan Allen, "from Object to Field". |
We are going to test a few ways of visualizing data. The data we have for testing is made of polygons or points. This data could be anything you may draw and map from any of your projects: cigarette buts on the floor, events on a part of the city, trees on a park, cars parked, lampposts… as long as they are represented by points or polygons anything could be our data. The points and polygons we have are originally from a GIS database (links are giving under "Resources" on this blog) of Stockholm, though we won't concentrate that much on the meaning of this information at this point. We will use them just to check techniques, later in the course we will use these techniques with data that may be meaningful to your project.
We will explain how to use this sample information, and how to process it through a small application or APPLET that we have developed for the course (downloadable at "Applets", on this blog).
The actual task, consist in producing a drawing from the data sets (the drawing could show one data set, or a comparison of different data sets, for example). The drawing should identify some important feature or pattern in the form the data set is represented: a boundary, a gradient (a direction of steepness, check the lexicon on the blog), valleys, holes, peaks… Use the chance to learn how the representation system works, test different ways of manipulating and analyzing it in your favorite modeling or CAD package. Be selective of the information you present, don't crowd too much information together, be clear and precise.
Some of the techniques you can use to represent these features :
-Boundary lines (boundary contour).
-Vertical Sections.
-Contour lines.
-Meshes and wireframes.
-You can download some test datasets formatted as dxf under "applets", from the blog, there are some more on the server space: ak3/A31REA Representation 3/Datasets.
Submission:
-Use the A3 Adobe Illustrator template, (downloadable from "Templates" on the blog) for submission.
-Submit your drawing to ak3/A31REA Representation 3/Övning_1
(it seems that the directories have been renamed, I have updated the references), as indicated in the "Server Space" post from last week.
-You should submit before the next day we meet, October 7.
