W12 Google Earth Wind Farm
Process
Summary
Factor
|
Criteria
|
Wind Speed
|
9.5 knot speed at time of criteria check. Wind speed dropped below the 5 knot minimum
about twelve hours in the four-day period of recording
|
Ornithology
|
There are quite a few species in the general area, but does not hinder
the major or minor flight path of migratory birds
|
Noise
|
Due to the distance from shore, noise is not a major factor for
residence or businesses
|
Shadow Flicker
|
Wind farm is too far from land to have any effect on residences or businesses
|
Shipping Impact
|
Wind farm will not be located in a shipping lane, so no impact on
trade.
|
Landscape & Visual Impact
|
At a height of 300 feet to top of turbine, they would be visible from
about 22 miles away. There is much
controversy as to whether the wind farm would be good or bad to look at. That is something that might need to be verified
by the use of PPGIS.

Selection Justification
Wind Farm Justification
The major criteria in looking for an area to build a
wind farm is there enough wind to turn the turbines so that enough electricity
is produced so there is a net gain or profit.
I looked for an area that had a high wind average over the last recorded
segment of time. The actual study of an
area would actually include a couple of years of study which we do not have the
time to do in this class for this scenario.
The bay I see as a good spot due to wind average and also due to the
fact that the wind will be channeled from the north between the land parcels.
The next factor I looked at was the impact on
ornithology. There are many species that
live in surrounding area, but the wind farm will not be in the major or minor
migratory path of birds. So far there is
very little to prove whether wind farms have any effect of bird populations.
With the distance to land, noise will not be a
problem even though noise travels further on water than land. It might bother boaters or fisherman, but
they have the ability to move to another location.
In reference to shadow flicker, the farm will be
located far enough away from residences and businesses to have very little
effect on them. Boaters and fishermen
will be main group affected by flicker.
Another factor to consider was the interference with
shipping. Since this is a bay, there is
no effect on shipping.
As far as landscape and visual impact, it comes down
to the preference of each person. You
would have to put up a turbine and actually have people see it from different
angles, distances, time of day, etc for people to really know how it
looks. Some people like them, some
people don’t. Some don’t like them just
because they are something new and different.
Some folks like them because they are new and different. This field is
totally subjective and can only be answered by a vote of each person that will
be able to see it.
There is a Danish study that shows there is very
little negative impact on the fish around a wind turbine farm of most
species. The wind farm actually
increased some fish populations that used the rocks around the wind farm as
well as the structures themselves for safety and protection. This might provide more sport fishing to
attract fishermen for the tourism trade.
There is much controversy on the placement of wind
farms. I have ready many articles about
a minimum distance that is a standard set by groups, but I bet you never see a
wind farm being placed that close to their residence. Then you have a proposal for a farm out in
the ocean that will have little impact on the majority of folks who will
benefit from it, but if there is a powerful U.S. Senator who does not want to
see it from his ‘castle’ at Hyannis Port Historic District, then it is likely
that wind farm will never be built.

PART II: Process Summary Details
1) Open ArcMap
2) Select Data_Editing_BED, click Open
3) Crtl-click to
select multiple layers
4) Right-click a layer and select Group
5) Rename New Group Layer to County
by clicking on it twice and typing in the new name
6) Right-click on ‘Group Layer’ and
select Ungroup
7) Select Create under Graphs
below the View drop-down
8) Select Vertical Bar under Graph type
and Buildings under Layer/Table
9) Select Height under Value field
10) Select Building under X label field
11) Leave Match with Layer under Color
12) Select New Series under the Add
tab to add another dataset
13) Click Next and then Finish
14) Right-click on the graph to view Properties and/or Advanced Properties
15) Right-click again on the graph and
select Add to Layout, your graph
should appear in the map layout
16) Switch to Layout View if it did not automatically switch
17) Close out all maps in ArcMap
18) On the Layout toolbar, click Change Layout
19) Click the Open File in the lower right hand corner
20) Navigate to a saved map that you
would like to use as a template and select it and click Open
21) Click Finish, in the Data Frame Order window
22) Now you can the add the data layers
you need to perform analysis and you have the template for your map
23) You will only have to shift item
around and add any title and text to each new map
24) Dynamic text
can be used to save time
25) Insert Text to
begin
26) Items that you want to remain the
same each time, just type in the box
27) Items that you want to change each
time or Dynamic will be inside ˂ ˃, left and right arrowhead
28) The following <dyn type =”date”> is equal to 4/10/2012
29) The following <dyn type =”date”, format ="dd MMMM yyyy"> is equal
to 10 April 2012
30) Dynamic tags can be used for anything
that you want to add to each map
31) Save map as a template, whatever name
you want for future use
32) Post to Blog and dropbox
Loose Ends Part 2
PART II: Process Summary Details
1) Copy data from R drive to S drive and
unzip
2) Open Windows Explorer and navigate to
a folder that contains GIS data
3) Double-click on any .mxd file to open
it in ArcMap
4) Right-click on a layer and select Create Layer Package
5) Select Save package file to and navigate to where you want to store the
file
6) Click Validate, if Share is
available, select it and go to step 9, if not go to step 7
7) If you receive an error, double-click
on the line showing error and make any necessary corrections, go back to step 6
8) You are now ready to share that layer
9) It can be “Unpacked” in ArcCatalog
10) To create a Map Package, everything
in ArcMap, click on File and select Create Map Package
11) Select Save package file to and navigate to where you want to store the
file

available, select it and go to step 9, if not go to step 7
13) If you receive an error, double-click
on the line showing error and make any necessary corrections, go back to step 6
14) You are now ready to share that map

·
Open GCT_PH1.xls in Excel
·
Copy counties to be used to another tab
·
Compute number of houses per dot to have at
least one dot per county
·
Will use 1 dot =5000
·
Test .7pt dot as recommended. Will use since I can’t figure out how to make
larger as a group
·
Place dots according to spreadsheet computations
for each required county
·
Trying to make dots appear closer to other dots
according to county housing units
·
Added Title, Legend, Source, Produced and
arranged items to appear visually correct
·
Working on background color, no luck, out of
time
·
Wetland layer messing with me with the image
·
