Project 2

Lake Shore Drive

For this second project you will deal with volumetric data. Some data of this kind is collected as with MRI or CT scans. Other data is a combination of sensor data and computer models. In this project we will be looking at the latter.

The data we will use comes from the Great Lakes Observing System
In particular we will be looking at the Lake Michigan History 3D data

In this dataset Lake Michigan is represented by a 250 x 130 grid (2km square grid cells) with 18 depths

Quick Viz of Lake Michigan Dataset

A general overview of Lake Michigan can be found on wikipedia at
Some quick facts: Lake Michigan is 494km by 190 km with an average depth of 85m. The deepest point is 281m.

There is data for the years 2006 through 2010 including temperature and horizontal water velocity every 3 hours, which gives a nice amount of data.

You job is to create an interactive visualization tool to let the user investigate this data.

You will use vtk in connection with a user interface toolkit of your choice to implement the project. You will need to be able to show this app in the classroom so be sure you have it running on an appropriate machine.

The application you develop should help the user investigate questions about Lake Michigan. You shouldn't be thinking of the application as the end product but as a means to get to the end product, which is knowledge, so its important that your application be easy to use and produce visualizations that are easy to understand. One of the requirements to get an A is to use your tool to find some interesting things in the dataset.

You can store the data in any way you prefer that gives you sufficient performance AND is sufficiently portable that andy can easily make your application run on his hardware. Databases are fine, on line storage is fine, flat files are fine.

For a C you should

For a B in addition you should

For an A in addition you should

You might also want to investigate writing an application that runs in 3D (the easy way being to do a left and right stereo pair where you duplicate the user interface but slightly offset the cameras in the two 3D views) as this data looks very nice that way.

Once you have this working, take a look at the data with your own application. Do you see anything interesting? Are there any patterns that show up? Given that you have this visualization too, what interesting things can you find in the data using your tool? What features show up better with different types of visualization?

You might find some things to look for at the epa
and also the summary of pressures for Lake Michigan and

You should create a set of web pages that describe your work on the project. This should include:
all of which should have plenty of screenshots with meaningful captions.

You should also create a 2-3 minute video showing the use of your application including narration with decent audio quality and that video should be linked to your main project web page.

I will be linking your web page to the course notes so please send me a 320 x 240 jpg photo of your visualization for the web. This should be named p2.<your_last_name>.jpg. Web pages like this can be very helpful later on in helping you build up a portfolio of your work when you start looking for a job.

Each student will bring his / her visualization to class to present it and describe its features to the rest of the class. This allows everyone to see a variety of solutions to the problem, and a variety of implementations.
