Introduction Geographic Information Systems, ArcView 8.1
Spring 2003 Instructor: Jim Taulman
The course will consist of registering individually and completing 2 online ESRI courses, Learning ArcGIS I and II. These courses explore ArcView 8.1. Your registration fee for the courses is $120 and the extra $100 beyond your $20 course fee is being funded by MIE.
The data for the first course are already loaded onto your computers under the directory “c:\arcgis\LearnArcGISI. When you get ready to do an exercise go ahead and open ArcMap as instructed and load the map (*.mxd) or data layer file from the appropriate subdirectory under that path. You don’t have to download these data off the network.
You are recommended to do as much of the day’s lesson as possible in class so that I will be there to assist with any questions. You are also encouraged to take the tests at the end of each section for your own benefit. You will also then earn the ESRI certificate for completion of the courses.
Grades will come from homework assignments. You have a directory called “homework” under your “arcgis” directory. Save your homework files into that directory. Each assignment will be due the following class period and will be worth a maximum of 5 points. There will be 20 homework assignments. When you get done with an assignment print out the resulting map and turn that in. Turn in homework on time. There will be a penalty for late work. Grades will follow standard format:
90 - 100 = A
80 - 89 = B
70 - 79 = C
60 - 69 = D
0 - 59 = F
Class starts at
If you are at PW during the week and want to work in the lab go to the MIE department and see Mike Fredenberg, Cliff Delong, or someone else down there and see if they will let you in.
There are 2 computers set up in the

Imagine that you’ve downloaded a map into your GIS that uses decimal degree units. Therefore when you go to measure a distance it will be in degrees; a polygon area will be in square degrees. So, you need to convert your decimal degrees to miles. Given the average radius of the earth is 3,961 miles, it is relatively straightforward to find the number of miles in latitude degrees. The assignment is to find how many miles are in a degree of longitude at 43 degrees latitude, about our latitude here. Assignment #3.

Editing spatial data in ArcGIS
Editing features
Modify SubdivisionParcels layer so
that the line from the SW corner vertex extends straight up to meet the top
boundary, forming a vertical western boundary of the parcels with no polygons
beyond it to the west. Save map as subparcels.mxd.
Hint: when vertices are displayed, right click on
one and select “move to” to see its x,y
coordinates which can be copied and pasted to another vertex’s
coordinates. Enter to save and the
vertex moves to the pasted coordinate. Assignment #5.
Feb. 27 Learning ArcGIS I, Module 4, Lesson 1
Displaying and manipulating attributes
Displaying attribute data
Editing feature attributes
In SubdivisionParcels edit the
LANDUSE field in the attribute table and change the eastern top and bottom 2
parcels to “COMM.”, change the central 4 top and bottom parcels landuse to “RES”, and change the western most 2 parcels landuse to “VAC”.
Now open the field calculator in the VALUE field and write an If/Then
statement to assign values for each parcel based on the area and value of
various LANDUSE categories.
Commercial parcels are valued at
$100/sq. m., residential at $50/sq. m., and vacant parcels at $30/sq. m.
1. What is the mean value of all 8
parcels? $48,719.20
2. What is the value of the SW
corner vacant parcel? $23,806.76
Hint: Go to Tools/Macros/Visual Basic Editor/Help
Under Help go to Visual Basic
Language Reference/Statements/If-Then Statements
Look at
the example and see how to write an If/Then statement with more than 2
conditions.
Your
If/Then statement will have 3 conditions corresponding to LANDUSE categories.
3. After you have answerd questions #1 and #2, color parcels according to LandUse, COMM, RES, VAC.
4. Label parcels with landuse category AND number each with FID from attribute
table.
(In
Properties, Labels, click “Expression” and Add the
additional attribute label)
5. In Tools/Graph, make a graph of
the Subdivision Parcels layer, showing values of each parcel and make a simple
bar graph, the default. Graph data
series using Records. Label
X axis with LANDUSE and show legend.
6. In top bar of graph right click
and “show on layout”.
7. Go to Layout View and arrange
graph and data frame to show each as large as possible on the page one above
the other.
8. Using “Add text” number the bars
along the X axis “1” through “8”.
9. If you want to confirm that the
numbered bars on the graph actually correspond to the same numbered parcels, go
back to the data view and layer properties and in Label Expression, add value
and display. Go back to Layout View and check
the values for each parcel with the value of the numbered bars on the
graph.
10. Once you’ve done this go back
and take out the values from the parcel map so that only the FID numbers and Landuse type show on the parcels.
11. Go back to the Layout View and
print it.
12. You can write the answers to
question #1 and #2 on the printed map and graph.
13. Save map as newsubparcel.mxd in your homework directory. Assignment #6.

Finding features using spatial relationships
Spatial queries
We want to find a business plaza suitable for building a new
public school campus serving K-12 grades.
We want it to be within 25 meters of a bus route and within 25 meters of
the block group with the highest number
of young people aged 0-19. You may
find it easiest to save each selection as a new shapefile
(not a personal geodatabase!).
Pick a
symbol that represents a school for your final choice of business plaza. (in symbol selector
look in “more symbols”/civic)
What is
the name of the chosen business plaza?
Save your map as that name. Label
the business plaza with its name. Make
these symbols and names large enough to read easily on your printed map.
Hint: start by finding block groups where numbers
of youth in our age group are > 200.

a) Go to your GIS class
directory and in the
b) Show
your waypoints and notice that you have 5 there in
c)
Export these waypoints as a .txt file from MapSource
and save them in the
d) in Programs/Accessories open a text editor – WordPad is
good.
e) notice the format of the points in this text file. This is not the format that ArcView wants.
f)
Reformat this text file by eliminating all columns except Name, Time, Date, and
x and y coordinates. Also add an ID
column for sequential numbering of waypoints.
If a column title is not there (like Time) you need to enter it. Make your columns “comma delimited” or
separated by commas and don’t leave any spaces between words or rows.
For example, your file will look like this in part:
Grid Lat/Lon hddd.ddddd°
Datum WGS 84
Header Name Description Type Position Altitude Depth Proximity Display
Mode Color Symbol Facility City State Country
Waypoint DOUBLE CRTD
Waypoint PORCUP CRTD
You want to make it look like this:
ID,NAME,TIME,DATE,Y,X
1,DOUBLE,
2PORCUP,
This format for event tables is needed to import into ArcMap and is shown in Lesson I of Displaying Locations
from Tabular Data.
Hint: x and y columns
don’t have to be in any particular order.
g) change names of waypoints
entered in GPS in the field to:
double – Double Fatality
porcup –
pwicon – Piya
Wiconi
RCCent –
WCMTSW –
h) save this text file as sample_pts_mod.txt in the
i) Open ArcMap to a new map and open the “samplemap.mxd”
in your
j) in ArcMap add data and add your
edited waypoint file
k) the .txt file will show up on your table of contents but you
won’t see your points on the map
l) right click on the waypoint file name and do “display x,y data”
m) now you see your points on the map in this “event” layer
n) right click on the event layer name and Export the file to a
shapefile.
Name it “sample_pts.shp” and save it to your
o) now you can remove our event layer and the .txt file from
the map. You have converted your GPS
points to an ArcView shapefile. Select a visible icon and color for your
waypoint indicators.
p) Open
your attribute table for the sample_pts shapefile and notice the data you entered with the column
headers you created in the text editor.
q) now save your map and close ArcMap
r) Open ArcCatalog and double click on the sample_pts
shapefile to open its properties.
s) scroll down the fields and in the first empty row at the
bottom enter “COUNTY”. Click the “text”
in the Data Type column and change the field length from 50 to 30 so you won’t
have so much empty space after your county name. Close ArcCatalog.
t) Now
open ArcMap again and open the samplemap. Look at your attribute table for the sample_pts shapefile and notice
that you now have a COUNTY field in the table.
u) on the Editor toolbar start editing this file and put in
Shannon for the first 3 points, Pennington for the 4th point, and
v) now save your samplemap map and you have your points in a shapefile with the counties where they are located added.
w) export your attribute table to a .txt file and print and
