• Understand the rationale for object-oriented design and programming.
• Understand data abstraction and abstract data types.
• Be able to design and implement simple Java classes and packages.
• Be able to document the design and implementation of small software systems.

In completing this assignment, you will develop a software application to analyze GPS data.

In instructor assigned teams of two you are to design and implement a software package that will analyze GPS data.

• *Minimum/Maximum/Average/Standard deviation of distance traveled per trip
• Minimum/Maximum/Average/Standard deviation of distance traveled without a turn
• Minimum/Maximum/Average/Standard deviation of the number of turns per trip
• *Minimum/Maximum/Average/Standard deviation of the travel speed
• *Minimum/Maximum/Average/Standard deviation of number of stops per trip
• *Minimum/Maximum/Average/Standard deviation of time per stop
• Minimum/Maximum/Average/Standard deviation of time stopped per trip
• Estimated number of stop signs (and their locations)
• Estimated number of stop lights (and their locations)
• *Number of unique parking spots used
• *Minimum/Maximum/Average/Standard deviation of the number of times parked in a particular parking spot
• Percent of time backing into a parking spot
• Percent of time backing out of a parking spot... not necessarily (100-answer to previous)
• Graphic image displaying routes
• etc...

Your program is required to calculate the answers to at least three of the *'d items.

There are three GPS data files available to you: smallgps.zip, gps.zip, and biggps.zip. Each file contains GPS data from multiple trips. Each trip represents one trip in my car. Typically these trips are either from my home to MSOE or back. The first few lines of the gps.zip file (unzipped) are:

Start time: 2004-03-05 11:09:23
record,fix,hour,min,sec,msec,latitude,longitude,alt
1,3,11,9,24,710,43.0835367,-88.0390017,702.09
2,3,11,9,26,310,43.0835367,-88.0390017,702.09
3,3,11,9,27,310,43.0835367,-88.0390017,702.09
...

The first line indicates the starting time for the first trip. The second line contains labels for the different fields associated with each record. The third line contains the data associated with the first data record. Each record includes (separated by commas) the record number, the number of satellites used to get a fix on the GPS receiver's position, the time the record was made (in hours, minutes, seconds, and milliseconds), the latitude, longitude, and altitude. These records continue until the end of the trip. Data for the second trip follow immediately after the first trip. In this particular example, the first trip has 1336 records. Here are lines 1337-1345 of the data file:

1335,4,11,31,52,750,43.0445550,-87.9081050,639.76
1336,4,11,31,53,750,43.0445550,-87.9081033,639.76
Start time: 2004-03-05 17:10:35
record,fix,hour,min,sec,msec,latitude,longitude,alt
1,3,17,10,36,380,43.0445983,-87.9081033,583.98
2,3,17,10,37,380,43.0445950,-87.9081017,583.98
3,3,17,10,38,380,43.0445917,-87.9081000,583.98
4,3,17,10,39,380,43.0445917,-87.9081033,587.27
5,3,17,10,40,380,43.0445850,-87.9081067,587.27

Note: Your program should work on all three files although it may take a significant amount of time to process the larger files.

You should submit a partial laboratory report each week that includes your design documentation and your activity log. You design documentation should identify the class(es) and associated methods you will implement to complete the assignment.

Use the lab 2 template file to use as a starting point for this report. You can just leave the other sections blank.

You should write a program that will ask the user to enter a trip number (N) and entry number (M) and display the latitude, longitude, and altitude for the M'th entry in the N'th trip in the smallgps.zip datafile.

At the beginning of lab, I will give you an N and M and ask you to demonstrate your program for me.

Continue using the XML file that you submitted in week 5.

The lab report need not be self-contained. Your report should include:

• Discussion including:
  • Sample program output
  • Problems you encountered (and how they were overcome)
  • How you did (or didn't) function as a team
  • Etc...
• An activity log indicating how much time you spent on each phase of the assignment. You should use the format found in the template XML file and report the time in the following categories:
  • Design
  • Coding
  • Debug (before you think it's working)
  • Test (after you think it's working)
  • Writing Report
  • Other
• Conclusions (what you learned, suggestions of how the assignment could be improved, things you would have done differently, etc.)
• Documented source code for your program.

As with any report you submit, correct spelling and grammar are required. In addition, your report should be submitted electronically following the Electronic submission guidelines. (You may wish to consult the XML help video and/or sample report before submitting your report.) Be sure to keep copies of all your files, in case something gets lost.

Your grade will depend on quality of design, clarity of code and documentation, as well as whether your program produces the correct results. If you have any questions, consult your instructor.
