TRANSCRIPT
Exercise 1: Add Layers from SDE
1. Open ArcMap by choosing it from Start >
All Programs > ArcGIS > ArcMap 10.1
NOTE: you can also create a shortcut to
ArcMap by right clicking ArcMap 10.1 here
and choosing Send to > Desktop (create
shortcut)
2. Click the Add Data button
3. Choose Database Connections from the
Look in dropdown
4. Double click the SDE (spatial database
engine) listing to connect to this database
& to view its layers
SDE contains both individual layers and layer groups. The aptly named layer group is exactly what you
might expect: a collection of related layers. These are maintained by specific departments for their GIS
and mapping needs.
Layer groups precede individual layers in SDE. You can tell them from individual layers by their icons.
Layer group Point layer Line layer Polygon layer
Double-click on any of the layer groups to view the layers that they contain.
5. Scroll to the right to view all of the layers
and layer groups that are contained in SDE
6. Add the County Assets point layer
a. Locate it in the layer list
b. Single click to highlight it
c. Click the Add button
This layer will now appear both on your
map and in the table of contents (TOC)
7. Choose the Add Data button again and
open your SDE connection to add more
layers
8. Add both the roads layer (lines) and the
parcels CAMA layer (polygons) at the same
time
a. Locate the roads layer in the layer
list
b. Single-click to highlight it
c. Locate the parcels CAMA layer in
the layer list
d. Hold down the control key while
you single-click to highlight it
e. Click the Add button
Holding down the control key allows you to choose
multiple layers at the same time. Without the
control key your new layer selection would replace
whichever layer you had previously highlighted.
Add Layers from Raster and GIS Server Connections
1. Click on the Catalog button to open the Catalog window in ArcMap
NOTE: press the F1 key on your keyboard while your mouse is hovered over this button to learn more
about the Catalog window. This shortcut to specific help documents works for many of the buttons
windows in ArcMap.
2. Click on the small plus to expand the
database connections list & double-click
on your Raster connection listing
This button will turn into a minus that
allows you to collapse the database
connections list after it is opened.
3. Expand the Raster connection to view all
available layers in this source
4. Locate the 2012 aerial photo layer
5. Click and drag it from the catalog window
to your table of contents
NOTE: layers can only be added one at a
time through the Catalog window
6. Expand the GIS Servers listing in the
Catalog window
7. Add the Carto Base Map by clicking and
dragging it from the Catalog window to
your table of contents
8. Add all of the following using either the add data button or through the Catalog window:
• A layer that contains point features
• A layer that contains linear features
• A layer that contains polygon features
• The Ortho base map
• Another raster layer
9. Remove one or more of the layers you
have added to your map by right-clicking
and choosing remove
\
Exercise 2: Working with Layer Visibility & Symbology
Turn layers on and off in the TOC
Layers are drawn on your map in the same
order you see them listed in the TOC. ArcMap
doesn’t care whether or not a layer is being
covered up by another; anything that is
turned on in the TOC is rendered on the map.
As such, it is a really good idea to uncheck any
layers that you aren’t currently viewing so
that your map draws more quickly.
1. Turn off all layers except for parcels
CAMA and the Carto base map
Change the drawing order of your layers
1. Click and drag the parcels CAMA layer to
the top of your layer list
2. Move the Carto Base Map layer to just
beneath the parcels CAMA layer
These layers are now drawn on top of any
other layers that you turn on in the table
of contents.
At this point your map looks something like this:
The polygon parcels layer, with whichever default
symbol ArcMap selected when the layer was
added, overlaps the carto base map completely.
There are a few things that you can do to make this
map more useful…
Make a layer more transparent
1. Double-click on the parcels CAMA layer in
the TOC to open the layer properties
window
2. Open the display tab if needed
3. Type a value into the transparent % text
box to set the layer transparency
65% is a good transparency to try first,
but a bit of trial and error is often needed
to achieve the best results.
Result: the carto base map can be seen through semi-transparent parcel boundaries
Change the parcels CAMA polygon
symbology
1. Change the parcels CAMA layer
transparency back to 0%
2. Open the layer properties again, this time
do so by right-clicking the layer name in
the table of contents & then choosing
properties from the context menu that
appears
3. Open the symbology tab
This tab in the layer properties window
displays the current symbol of the layer.
Symbology for this layer can be adjusted
through this tab as well.
4. Click on the current symbol to open the
symbol selector window
5. Click on the current fill color swatch to
open a menu with different color choices
6. Choose No Color
7. Use the up arrow to change the outline
width to 1 instead of 0.40
8. Click OK to apply the change
9. Click OK again to close the layer
properties window
This window also
appears when you click
the outline color swatch.
Result: hollow parcel polygons are drawn on top of the carto base map

(currently filtered by a search for library symbols in
the image)
10. Zoom in to view a smaller area on the map
11. Add the following layers to your map (if
they haven’t been added previously)
• Libraries
• Railroads
• Parcels CAMA
• Ortho base map
12. Remove any other layers from your map
13. Adjust the drawing order, if needed, to
match the order listed in step 11
14. Make the following changes to the
symbology on your map
• Search for library symbols and choose
one of the results for the libraries layer
• Find an appropriate symbol for the
railroads layer & change the line
weight and line color
• Make the parcels CAMA polygons
hollow with a bright yellow outline
Exercise 3
1. Add the county assets layer to your map from SDE
2. Open the attribute table and note the fields that might be useful
Right-click the layer name in the TOC > Open attribute table
OPTIONAL
3. Turn off the fields that you don’t intend to
use
a. Open the layer properties window
b. Click on the fields tab
c. Uncheck the boxes of any fields
that you want to hide in this layer
In this exercise you will definitely be using
the asset category, name, and address
columns;
Use the Find Tool to Locate and Zoom to the Cedar Creek Fire Station
1. Select the find tool
2. Enter your search string
3. Choose the layer the find tool will search
4. Narrow the find tool search to the
appropriate attribute table column
5. Click Find
6. Right-click the correct result (in some
cases there may be more than 1)
7. Choose Zoom to from the context menu
that appears
Enable and configure the map tips to display the address field
1. Open the layer properties and choose the display tab
2. Check the ‘display Map Tips using the
display expression’ checkbox to enable
map tips
3. Choose ADDRESS from the field dropdown
menu
4. Click OK
5. Test your map tips by hovering over one of
the county asset features on your map
Symbolize the County Assets Layer by Category
1. Open the layer properties window and choose the symbology tab
2. Choose categories > unique values from
the ‘show:’ options
Features is always the default choice when
a layer is added to ArcMap. To visualize
groups that share values in a specific field,
we’ll need to change this display type.
3. Choose CATEGORY from the Value Field
dropdown
This tells ArcMap how you want to
categorize this layer.
4. Pick a color ramp
5. Click the add all values button
Make all of the symbols a little bit larger
6. Right-click on one of the symbols and
choosing properties for all symbols
7. Use the up arrow to change the symbol
size to 8
8. Click OK to apply the new symbol size
9. Click OK to apply the symbology to the
County Assets layer
10. Zoom out to the full layer extent to view
your new symbology
Right-click layer name in the TOC > Zoom
to layer
Label the County Assets Layer by Asset Name
1. Open the layer properties window & select the labels tab
2. Check the ‘Label features in this layer’
checkbox to enable labeling for this layer
3. Choose ASSET_NAME from the label field
dropdown
This dropdown tells ArcMap which column
you want to use to label the features in
this layer
4. Modify the labeling text font, style, side
and/or color to suit your map and personal
taste
5. Use the Scale Range… button to only
display labels when you are zoomed in to a
scale of 1:10,000 or closer
a. Click the Scale Range… button
b. Adjust the settings to ‘Don’t show
when zoomed’
Out beyond:
1:10,000
c. Click OK to close this window
d. Click OK to apply all of your
labeling choices to the map
6. Zoom in to a scale 1:10,000 or closer to
view your new labels
