Problem:  Create a map for your employer, an up-and-coming cellular communications company, that displays suitable sites for cellular antennae along Lee County Highway Corridors.

Procedure Log:

Data:   ArcView shapefiles provided by the City of Sanford GIS Department:

	towers.shp - Towers located within either Lee County, NC (point)
	streets.shp - Streets that are located within Lee County, NC (line)
	sanford.shp - Expanse of the City Limits of Sanford, NC (polygon)
	leeco.shp - Expanse of Lee County, NC (polygon)
	

	map units for all shapefiles:  Feet


Use Select by Location to determine the towers that are within the City Limits of Sanford:
	
	Target layer:  towers.shp
	Selection option:  Select features from
	Selection option:  Are completely within
	Selection layer:  sanford.shp
	Result:  12 records selected from towers.shp

Use Select by Attributes to determine the towers that are at least 150 feet high and are a communication type of tower:
	
	Target layer:  towers.shp
	Selection option:  select from current expression
	Selection expression:  "USE" = 'COMMUNICATION' AND HEIGHT > 150
	Result:  7 records selected from towers.shp

Use Select by Attributes to find highways named Boone Trail, Jefferson Davis, Horner, US 421, and Highway 87 South:
	
	Target layer:  streets.shp
	Selection option:  create a new selection
	Selection expression:  "NAME" = 'BOONE TRAIL' OR "NAME" = 'JEFFERSON DAVIS' OR "NAME" = 'HORNER' OR "NAME" = 'US 421' OR "NAME" = 'HIGHWAY 87 SOUTH'
	Result:  131 records selected from streets.shp

Use Select by Location to find towers that are within 1000 feet of the previously selected streets:
	
	Selection option:  Select from the currently selected features in
	Target layer:  towers.shp
	Selection option:  are within a distance of
	Selection layer:  streets.shp
	Method:  Enter 1000 feet as the buffer criteria
	Result:  5 records selected from towers.shp

Create a 'virtual' layer of the selected towers from the towers shapefile via the Selection dialog:
	
	Target layer:  towers.shp
	Selection option:  Create layer from Selected Features
	Result:  New 'virtual' layer created from towers.shp  (Note:  Layer renamed "suitable towers"; shape changed to Cellular Phone 1 from the Telecom category, color changed to red and size changed to '15'.)

Create a 'virtual' layer of the selected roads from the streets shapefile via the Selection dialog:
	
	Target layer:  streets.shp
	Selection option:  Create layer from Selected Features
	Result:  New 'virtual' layer created from streets.shp  (Note:  Layer renamed "highway corridors"; shape changed to Highway, color changed to blue and width changed to '1'.)

Use Select by Location to select the towers that are inside of the City Limits of Sanford, NC:
	
	Selection option:  Select features from
	Target layer:  towers.shp
	Selection option:  are completely within
	Selection layer:  sanford.shp
	Result:  12 records selected from towers.shp

Use the Open Attribute Table to select the towers that are outside the City Limits of Sanford, NC:
	
	Method:  Select the Options Icon at the bottom of the Open Attribute Table Dialog.
	Selection option:  Switch Selection
	Result:  15 records selected from towers.shp

Use Select by Attributes to locate the Jefferson Davis Highway:
	
	(Note:  Don't forget to Clear Selection from the streets shapefile before peforming further functions.)
	Target layer:  streets.shp
	Selection option:  Create a new selection
	Selection expression:  "NAME" = 'JEFFERSON DAVIS'
	Result:  50 records selected from streets.shp

Create a 'virtual' layer of the selected roads from the streets shapefile via the Selection dialog:

	Target layer:  streets.shp
	Selection option:  Create layer from Selected Features
	Result:  New 'virtual' layer created from streets.shp (Note:  Layer renamed 'Jefferson Davis Highway'.)

Use Joins and Relates to perform a spatial join on the towers shapefile with the Jefferson Davis Highway layer:
	
	(Note:  Don't forget to Clear Selection from the towers shapefile before peforming further functions.)
	Target layer:  towers.shp
	Method:  Joins from the Joins and Relates Menu
	Selection option:  Join data from another layer based on spatial location.
	Selection layer:  Jefferson Davis Highway.shp
	Selection option:  Each line will be given all the attributes of the point that is closest to it, and a distance field showing how close that point is in map units.
	Output layer:  C:\Documents and Settings\User\My Documents\PRT462 Files\Assignment6 Folder\Join_Output
	Result:  A 'virtual' layer is created named "Join_Output" which displays the joined data plus a distance field.

Use the Open Attribute Table to determine the distance of the tower that is farthest from the Jefferson Davis Highway:

	Target Layer:  Join_Output.shp
	Method:  Right-click the top of the "Distance" field column.
	Selection option:  Sort Ascending
	Method:  Find the last record in the Attribute Table and find the value in FID field.
	Result:  The value in the FID field is 10.
