Data - Exercise 2
Scenario:
Using the map from Exercise 1,
your supervisor would like some more information, including a breakdown
of ozone monitors by county instead of ozone regions, and asks that in
the inset map you add major roads for more detail.
Step 1
Determine status of certain monitors
Use the 'Identify'
tool on the
'Tools' toolbar to click on
some features to see their attributes. Try identifying the
following ozone monitors and see whether or not they are active sites
(indicated by the SITE_STATU field - I = inactive, A = active):
1.) Ashland ______________
2.) Jonesport _____________
3.) RCIP _______
4.) Kennebunkport ________
Also try clicking on some of the towns to see their attributes.
Step
2 Summarizing by county
Historically, counties have often been
used in determining
compliance with air quality regulations. In this step, you will
look at the distribution of ozone monitors in counties as opposed to
regions. Do this by adding the 'Counties' layer
to the map, turning
it on, and using the 'Identify'
tool.
Try to answer the following questions:
5.) How many monitors are in Piscataquis
County?______________
6.) Which county is the Jonesport monitor
in?___________________
7.) Which county has the most
monitors?______________________
8.) Which counties have no
monitors?__________________________
Once you have
completed
this analysis, remove
the Counties layer.
Step 3 Feature types
Visually examine the following layers and determine what type of features are
used in the layer (point, line, or polygon):
9.) Ozone monitors________________
10.) MidCoastal Area_______________
What types of features
would be
appropriate for the following data
(point, line, or polygon - may be more than one correct answer)
11.) Elevation contours_____________
12.) Lakes_______________________
13.) Rivers_______________________
14.) Drinking wells________________
15.) Storage tanks________________
16.) Vegetation___________________
Step 4 Adding
the major roads
Currently, the
only data in your map are the towns (grouped into different regional
layers), and the ozone monitors. To add clarity to the inset map,
you have been asked to add the major roads layer. First, activate the 'Inset
of Acadia' data frame.
Then, add the
Major Roads layer to that data frame
(remember where to
find it?).
Where
would you find
the following data:
17.) aerial photos __________________________
18.) bedrock geology information______________
19.) licensed wastewater facilities_____________
Challenge In step 4
above, what would happen if you had NOT activated the 'Inset of Acadia'
data frame?
