The GIS lab equipment |
Macintosh network consisting of a mix of imac, G3, and G4 computers | |
Scanner stations for scanning maps and airphotos etc. | |
Instructor station with projector | |
Server computer (where the applications are stored) | |
Printers (that we can’t use!) | |
Sound system (for passing the time while working on assignments) |
GIS lab policy |
Food and drink are not permitted in the lab | |
Please do not abuse the equipment - no matter how frustrated you get | |
Drop in usage outside of scheduled lab/lecture sessions is permitted provided there is a lab supervisor present | |
The lab equipment is available for other course work or for personal use (ex. Internet). |
GIS Lab Supervisors |
Student volunteers who are responsible for supervising the lab during the week | ||
Duties: | ||
Supervise the lab during one assigned time slot per week | ||
Secure the lab at the end of their shift | ||
Enforce lab policy | ||
Benefits: | ||
Freedom to open the lab when they wish - (i.e. to work on assignments in the middle of the night) | ||
Experience in supervising a computer lab |
Lab Supervisors (continued) |
Watch for posters announcing the call for lab supervisors | |
Or approach Dr. Pazner at the next lecture | |
Or email the coordinator: Daniel Fox at djfox@uwo.ca if you are interested | |
You will need to attend an orientation session |
Introducing Macintosh |
A desktop environment quite similar to Windows on PCs | |
The menu bar at the top of the screen functions in much the same way as the task bar in Windows | |
The desktop includes some familiar icons such as the Trashcan | |
and some not so familiar icons (ex. Harddrive and networked Harddrive icons) |
Logging into the machines |
Turn the machine on | ||
After a minute or so it will ask you to log in | ||
Read the label on the front of your machine | ||
The user name is GISCIxx | ||
The password is GISCIxx | ||
"“Apple”" |
“Apple” menu | ||
Roughly equivalent to the “Start” button in Windows | ||
Provides access to recent applications | ||
and the “Chooser” (more on this in future) | ||
File, Edit, View, and Help menus | ||
Fairly self explanatory | ||
Special menu | ||
Used to shut down or reboot the system | ||
Also for emptying the trash can |
The Finder |
Located in the top right part of the screen | |
A list of the applications running on the system | |
Go here to switch applications and check which applications are running | |
Functions like the taskbar in windows |
Useful applications |
Sherlock - for finding lost files, folders, or applications | |
Start it from the “Apple” menu or hold down the ð key and press F (for Find) |
Other useful applications |
SimpleText - a very simple text editor for looking at the output from GIS work or for taking notes | |
Microsoft Word and Excel for writing up your assignment answers or doing spreadsheet work | |
Internet Explorer and Netscape - research or just plan surfing | |
Photoshop for scanning and image processing | |
and Corel Draw for layout and graphic design work |
Zip disks |
At least one Mac formatted Zip disk is required for this course | |
Strongly recommended that you have 2 disks though - one to act as a safe backup | |
Zip disks have been known to die in this lab! |
Temporary Hard Drive space |
There is a folder on each machine for temporary storage of your files | |
I recommend using the hard drive during your work sessions and then saving your work at the end of each session to your zip |
Working on Assignments |
Every assignment will consist of a number of elements: | ||
Map files | ||
Script files | ||
A Project file | ||
Written answers | ||
For the sake of organization, make a new folder for each assignment and store these elements in this folder. |
Do this now… |
Double-click your computer’s hard drive icon | |
Double-click the temporary user files folder | |
Choose the File menu and select New Folder | |
Name the new folder “Assignment#1-yourname” |
You should make a new folder at the beginning of each new assignment - and store all the files for that assignment in that folder |
MFworks Raster GIS Program |
A GIS software package developed here at UWO by Dr. Pazner and two of his colleagues | |
This program is a “user” friendly introduction to GIS and its concepts |
Start MFworks |
On the desktop, double-click on the network hard drive icon (labeled OSX1B) | |
Find and double-click the Applications folder | |
Double-click the MFworks folder | |
Double-click the MFworks 2.6.3 icon |
MFworks environment |
MFworks starts up looking like this | |
Notice the Untitled Project window | |
This window is used to keep track of related maps |
Assignment #1: Learning about MFworks |
A simple assignment to (re)familiarize you with MFworks | |

A script is a ‘recipe’ of operations | |
You will be required to produce scripts files for your assignments | |
Making a Script file |
Choose Windows menu | |
Select New Script… | |
Write up your script | |
Be sure to save your Script in the Assignment#1 folder |
Essential Elements of Scripts |
Clean formatting to make it easy to read | |
