You can work in pair-programming mode on this homework assignment.


Your Assignment


  • Your assignment is to generate a partial map of Smith with at least 15 buildings and color them according to their age.
Buildings built in 1700 to 1799 will be of a given color (your choice of color). Buildings built between 1800 and 1899 of a different color (your choice as well). Buildings built between 1900 and 1999 of a third color, and finally buildings built after 2000 in a fourth color. You can pick the colors, and they must all be different from each other.


  • Your program will display a legend on the image, made of 4 rectangles containing the 4 colors introduced above, and the year-range displayed next to them. You are free to organize the rectangles as you wish, either horizontally, or vertically, at the top of the map, bottom of the map, or on the sides of the map. If you're not sure what a legend looks like, take a look at a Google image search with the key terms "legend graph example".


  • Your program should be called hw12a.py.


  • Your program should contain the following statement at its top, right below the program header:


from buildingAges import buildingAgesText


(The details about the file buildingAgges.py are given below.)


  • You may use some of the buildings provided at the end of the page to get started, but you will have to add others. This list is provided AS-IS. You may use it or not.


  • Note that you should make sure that the building names in your csv file match the names found in the buildingAges.py file.


  • Your program should display your name or names at the bottom of the map, in a statement of the type "Map generated by Minnie Mouse and Pluto.".


  • Pick buildings for which we have a date of inauguration (not all buildings on campus are included in the list provided below).


  • Submit a copy of your map as hw12a.png, or hw12a.jpg, depending on how you capture the image. Please refer to take-a-screenshot.org if you do not know how to do this.



Smith Buildings And Dates of Inauguration: buildingAges.py


Save the program below in a file called it buildingAges.py and put it in the same directory where you are developing your hw12a.py program.

Map-Digitizer Program

SmithMapSmall.gif


To digitize additional buildings from the Smith campus using the image on the right, you can use/edit/modify/get inspired by the program below. Read it well first to understand what it needs and what it generates.

# MapDigitizer.py
# D. Thiebaut
#
# This program imports the file SmithMapSmall.gif and displays it on the canvas.
# The user then must use the + symbol in the menu to start the digitization, which
# first asks the user to enter the name of the building.  The user then clicks on vertices
# of the building's outline to record their coordinates.  When the user has gone around the
# full building, she clicks on the minus symbol of the menu.   The program then writes the
# csv representation of the building to a file called buildings.csv.
