ArcGIS ArcView 9.1 Homework Exercise #4
Assigned: November 2
Due: November 22 by 5 p.m.
Use ArcGIS ArcView 9.1 software to accomplish the following GIS
tasks and to answer the following questions. You will need to use
some of your GIS skills that you've already learned in Chapters 1-6 and
8-9 (including the tutorials) in Getting to Know ArcGIS Desktop;
in addition you will need many of the new skills that will be covered
in Chapters 14, 15, 16, 18 and 19 in order to do this exercise
efficiently and effectively. You will be collecting some
field data using GPS receivers, creating new features using on-screen
digitizing, and using the datasets available on the student i:
drive. You will have to work
consistently and diligently to complete the exercise by the deadline.
Problem

GPS, DOQ, DRG
- Using a GPS receiver find the location and elevation of the
following five locations on the NSU campus in UTM coordinates. Locations:
- South intersection of the sidewalk going through Beta Field
with the sidewalk on the western side of Muskogee Avenue (the
circular area where Muskogee Avenue merges with Valley Drive [Valley
Drive is the short link between Muskogee Avenue and Grand Avenue].
- Middle of the eastern edge of the crosswalk across Grand
Avenue on the west side of the Business & Technology Building.
- Light pole on the lawn between the Administration Building
and the Center for the Performing Arts.
- Northeast corner of the driveway leading out of the
parking lot on south side of Valley Drive across the street from the
Administration Building measured at the edge of Valley Drive.
- Middle of the pedestrian bridge that crosses the concrete
creek on Lewis Avenue east of the NET Building and west of the Physical
Plant.
In order to better estimate the coordinates of these locations using
the simple GPS receivers that we have, take three repeated measurements
at each location on two different days (six measurements total at each
location). Individual measurements on a given day must be
separated by at least one minute of elapsed time. It is your
decision as to which datum
to use. Use the worksheet available as a WordPerfect file
(GPS-worksheet.wpd)
on the i:\\student\transfer\ziehr\GIS-HW4 drive on the network.to
record
your data. Turn in your worksheet.
- Create a dBase (.dbf) file of your GPS coordinates
- Be sure you construct your dBASE file (or files, if you
choose) so that all of the coordinates for a given location (such as at
Beta Field) can be mapped separately from the other locations
(displayed using different symbols). Save your file or files (be
sure yourlastname is a part of the filename) on a
medium that can be turned in (or sent via e-mail)..
- Create two map documents (yourlastname-HW4-Prob1A and
yourlastname-HW4-Prob1B)
- Use the DOQQ of Tahlequah (.sid) in the
i:\\student\transfer\ziehr\GIS-HW4 folder for the first map (Prob1A)
- Use the DRG (.tif file) of the Tahlequah quadrangle in the
i:\\student\transfer\ziehr\GIS-HW4 folder for the second map (Prob1B)
- Display the points for which you collected coordinates (using
the GPS) on
each of these maps; this is accomplished by adding x,y data to the
maps. Show the points for each location (Beta Field,
Light Pole, Bridge, etc.)
using a different symbol (shape and/or color)
- Write a description of your results
- Describe how well your GPS coordinates relate to the two maps
and what you believe accounts for this relationship.
- Turn in a printed copy of your answer (or send in a clearly
named Word, WordPerfect, or Rich Text Format document-be sure your last
name is a part of the filename).
- Turn in your dBase file and your two map document files.
Problem

On-screen digitizing and creating geodatabases
- Create a personal geodatabase meeting the following
requirements:
- Include three feature classes; one each for streets, traffic
signals,
and neighborhoods. Each spatial feature in each class should at
least
have a name attribute; you may include other attributes if you
wish.
- Use the Tahlequah DOQQ (35094h83.sid--that's a Mr. Sid
formatted file) in the i:\\student\transfer\ziehr\GIS-HW4 folder as a
reference for on-screen digitizing.
- Digitize as line features the following streets, avenues,
drives,
and/or lanes: Bertha Parker By-Pass (eastside by-pass), Crafton,
Downing, Grand, Valley, and Muskogee (you might need to use
Mapquest.com to find these roadways).
- Make your own decision about where Downing Street ends on
the east side of town, but at least extend it to Bliss Avenue.
- Extend Muskogee Avenue at least to its intersection with
the Bertha
Parker By-Pass on the south side of town.
- The northern extent of the Bertha Parker By-Pass should go
at least as far as its intersection with Grand Avenue.
- Digitize as point features all the currently operating traffic
signals along Muskogee Avenue and Downing Street. The choices
you make as to where to end the three streets mentioned above will also
influence
which traffic signals to include; so everyone may not necessarily have
the
same ones on their maps.
- Digitize three contiguous "neighborhoods" or portions of the
city
as polygon features. I've made up three names Northeast
(the
polygon bounded by Bertha Parker By-pass, Crafton, and Grand), East
Central
(bounded by Bertha Parker By-Pass, Crafton, Downing, Grand, Muskogee,
and
Valley), Southeast (bounded by Bertha Parker By-Pass, Downing,
and
Muskogee).
- Be sure all the spatial features share the appropriate
vertices and/or edges (no overshoots, undershoots, slivers, and gaps).
- Save your geodatabase on a transportable medium (floppy or CD
or send via e-mail). The filename of your geodatabase must be yourlastname-HW4-Prob2.mdb.
- Create a Map Document that displays all the spatial features
in
your geodatabase on top of the Tahlequah DOQQ.
- Make sure your legend is clearly labeled. You don't have
to create a layout; just a map view will do.
- Bonus (+2 points): display the three "neigborhoods" in
different colors.
- Save your map document on a transportable medium (or send via
e-mail) using yourlastname-HW4-Prob2.mxd as the filename.
- Turn in your map document and your geodatabase files.
