In-Depth Information
Team C will measure the x-coordinates (the eastings) of the set of computers and will measure the
width of the room.
❏
Team D will measure the y-coordinates (the northings) of the set of computers and will measure the
length of the room.
❏
These data sets will also be e-mailed to the instructor.
The instructor will put the four data files in a shared area on the class computer disk. Students will
examine the pairs of data files for errors and inconsistencies.
Undertaking the Data Entry Process
If you did the fieldwork data collection (detailed in the preceding discussion of this exercise) skip ahead
to Step 1 below. If you chose not to do the fieldwork and want only to do the software-based part of the
exercise, proceed as follows:
Find the Excel spreadsheet in [__]IGIS-Arc_AUX named
Exercise_5-8_Student_Computer_Data.xls
There are two sheets there, one named Computers and the other named People (accessed with tabs
at the bottom of the window). The data in Computers should be typed into the text file Coordinates.txt
(described below). The data in People is to be placed in the dBase table named Student_Info.dbf (also
described below).
1.
Using MS Windows, in ___IGIS-Arc_
YourInitials
, make a new folder called
Student_Data_Collection.
Making a Table That Contains the Coordinate Data
2.
Using Notepad, or another text processor, make a text file that contains the coordinate data.
Call it Coordinates.txt and put it in the Student_Data_Collection folder. Each line should contain
three values, using CSV (comma separated values) format:
18
Each student's three-digit ID
The easting value (x-coordinate) of the computer terminal
The northing value (y-coordinate) of the computer terminal
For example, lines 2, 3, and so on should look like:
612, 10.28, 20.05
606, 10.99, 21.22
etc.
18
If you have not done the data collection part of this exercise go to the spreadsheet in [__]IGIS-Arc_AUX named
Exercise_5-8_Student_Computer_Data.xls and use the data there.
