Goal and Background
My goals for this lab were to learn how to
create a geodatabase in ArcCatalog, use a Trimble Juno GPS to collect spatial
data of the new UW-Eau Claire campus mall, and to create a map that includes
the features I collected with the GPS.
Methods
The first step I took
for Lab 3 was to make a new geodatabase in ArcCatalog and add point, line, and
polygon feature classes to the database. Next, I imported a shape file of the
buildings on campus and a raster of the UW-Eau Claire campus to the
geodatabase. Then I used the extension called the ArcPad Data Manager in ArcGIS
to set up my data to be used on the Trimble Juno GPS by choosing the option to
check out my geodatabase layers. Next, I deployed my geodatabase folder to the
Trimble Juno so I could go to the campus mall and collect my data. The next
step I took was to go to the campus mall and collect point, line, and polygon
features. I made sure that my GPS was activated so that I could get satellite
signals. I collected six grassy areas using the point averaging and streaming
data collection techniques. In addition, I collected the location of one line
feature (the footbridge) and six point features which included trees and light
poles located on the campus mall. I made sure to enter attribute information
for each feature I collected. For example, I entered whether a specific point
was a light pole or a tree. After I collected all of my features on the GPS I
checked my data back into ArcMap by using the ArcPad Data Manager tool. As I
checked in my data I made sure to select the point, line, and polygon features
I collected to add to my map. Now I was ready to start creating my map. I chose
appropriate symbols to represent each feature on the map. I made the symbol for
the campus buildings a light color to de-emphasize them because the buildings
are not the focus of the map. To finish my map I included the main components
of a map such as a title, legend, north arrow, scale bar, source information,
the date the data was collected, and the date the map was created.
Results
The Old Davies
Student Center was recently demolished and a new campus mall with walkways and
green spaces was constructed that took its place. The campus imagery in the map
has not been updated and still includes the location of the Old Davies Center.
In the map the new green spaces overlap the Old Davies Center building. In the
map I located new trees and light poles that were placed in the new campus mall
area. I also included the footbridge on campus as a line feature.
