Final Project

This is the final project for this class.

My proposal was to find a location for a community wind farm on the DelMarVa Peninsula (Delaware, Maryland, Virginia Peninsula).  The criteria was to find a suitable location with appropriate wind speed, land and population while avoiding sensitive environmental locations and schools.  I do not have access to the I:drive right now to be able to link to it so I have presented the slide presentation and summary here as jpg images until I can get access to the I:drive again.















This is my slide by slide summary. I felt that I was successful at obtaining my goal of finding a good location for the wind farm.  I found that when I used the tools I specifially needed for the analysis I came up with good results.  My original proposal said that I would use different analysis tools but I realized I was trying to find ways to use these tools instead of just using the best tools for problem at hand.

Local Property Appraisal Participation Assignment


Part 1: Research Local Property Appraisal Services
1. Conduct a web search to locate a property appraiser's office in your area.
- Does your property appraiser offer a web mapping site?
* No, the property appraiser does not offer a web mapping site.  In fact, every appraiser site I looked at in the Tri-State (Delmarva) area is very basic, they do not offer web mapping or selling prices or recent properties assessed.
* The website I chose is: http://fielsappraising.com/services.html
* They do not state how you obtain your data either.

2. Most property appraiser's websites offer a list of recent property sales by month.
- What is the selling price of this property?
*As I said above, none of the sites list selling price of any properties.

3. The selling price and assessed price will differ in most cases. 
- What is the assessed land value?
* total value is $20,000 with improvements
- Based on the land record data, is the assessed land value higher or lower than the last sale price?
* higher



Q4. Share additional information about this piece of land that you find interesting.  Many times, a link to the deed will be available providing more insight to the sale.
* There is no link to the deed.  However, this house is on a finger of a river, is highly elevated for this area and is an old property with only 3 owners.

Part II: Mappingn Assessment Values

Q1. Which accounts do you think need review based on land value and what you've learned about assessment?
* Looking at the map, other than the 4 corner pieces which are not developable, there are 6 properties that are of much lesser value than the surrounding properties.  They are: 090310105, 09031071, 090310320, 090310325, 090310260, 090310245.

Homeland Security: Protect

This lab was a second part to a lab we started last week. Last week we gathered the data and prepare our information.

This week the objectives were to be able to:
- Create a hillshade surface in ArcMap
- Edit attribute features in ArcMap
- Create new point data
- Create a new shapefile within ArcCatalog
- Create a line of sight
- View 3D data in ArcScene






This is a map of the Helioport at Cheyenne Mountain with a 500 foot buffer around the Helioport and a 3 mile buffer around NORAD and the Helioport.  I included 2 small maps of the area for reference.
















This map is of the Ingress and Egress Routes, particularly where the local roads intersect with the 500 foot buffer zone around the Helioport.  I, again, included map insets for reference.















PART III: Process Summary Details 
III. Site surveillance Locations around Critical Infrastructure

I have to say that this was not as fun an exercise as I thought it would be when I read over the notes.  It seemed very awkward and was hard for me to determine if I was doing it correctly…most likely because so much of the projects have given me issues that I just don’t trust it is coming out right.
i.       Generate Hillshade

1.       Used the 3D Analyst  for the Elevation group layer to create the “Hillshade” relief area.  Used 270 for azimuth, 39 for altitude and Model Shadows for the template.
2.       Created a new shapefile in ArcCatalog called “CMB_surveil_pts”
3.       Added surveillance points to the hillside using the Edit tool.

ii.       Generate Viewshed
1.      Used the 3D Analyst tool for Elevation group layer to create the “Viewshed” area to check visible coverage from surveillance sites..
2.      Set the parameters for default for the first one.
3.      Added a field to the Surveillance Points attribute table and set new field to 10  to account for setting the surveillance points on a 30ft tower.
4.      Ran the Viewshed analysis again to see new visibility.

 
iii.      Create line of sight
1.      Used the 3DAnalyst tool for Elevation group layer with the ‘Create Line of Sight’ tool. 
2.      Used 10 as the observer offset and 1 as the target offset to compensate for the 30ft NORAD entrance height and viewing objects low to the ground.
3.      Worked with this tool a bit to see the surveillance areas.
4.      Created ‘Line of Sight Profile Graph’ using the ‘Create Profile Graph’ on the 3D analyst tool.
5.      Exported graph and added  to Deliverable 3.
 
v.      
View 3D line of sight
1.      Opened ArcScene from the 3D Analyst toolbar.
2.      Added the Elevation layer (by typing in Elevation, it would not come up in a drop down box)
3.      I was told the solution to figuring out how to get my TOC to show so was then able to keep working on the lab.
4.      Using the Base Heights tab in Properties, selected ‘Floating on a Custom Surface’ and made sure the Elevation layer selected.
5.      Repeated with the NORAD layer.
6.      Neither image looked very good.  The Elevation layer did not change too much from 2D to 3D and the NORAD layer was really jagged looking.
7.      Used the Navigate tool to rotate the layer to show the road and tunnel, this took quite a bit of time and it never did look right.
8.      Copied and pasted the line of sight polylines. 
9.      I had to zoom in quite a bit to see this and the polylines did not match up with the NORAD layer. 
10.  As I tried to export the 3D image into a jpg, the jpg option never showed.  According to other students, only the 2D image allowed exporting to a jpg, so I did this. Saved and exported  as CMB_HS_Colorado_LineOSight.jpg.

Japan Tsunami Lab

This lab was in two parts and was based on the Tsunami that hit Japan and damaged the Fukushima Nuclear Power Plant.  We assessed the areas damaged, the evacuation zones at different distances and the population affected. 

The objectives for the first part of the lab were to:
- Understanding geodatabases in ArcGIS
- Creating a file geodatabase in ArcCatalog

The objectives for the second part of the lab were to:
- Create and work from a file geodatabase in ArcMap
- Map the evacuation zones surrounding the Fukushima-Daiichi Nuclear Power Plant
- Determine the at-risk population within each of those zones

This lab was a little easier for me than the last two until I tried to put the final map together. As I was trying to upload the final map here I noticed that it is missing elements, important ones. This screenshot shows what the map looks like in ArcMap - Print Preview.















This is what is apparently showing up as the exported jpg:




















Part I: Building a File Geodatabase



1)      Reviewed all the layers available

2)      Created a new file geodatabase “Tsunami.gdb” and added the feature datasets with WGS1984_UTM54N projections:

1.      Transportation

2.      Damage_Assessment

3.      Administrative

3)      Added the layers to the appropriate datasets.

4)      Built a new raster dataset from the DEM elevation rasters using the Data Management tools – Build Raster Attribute Table.

5)      Created Raster Dataset using New – Raster Dataset in ArcCatolog.



Part II: Fukushima Radiation Exposure Zones

1)      Added the layers:

a.       JpnBndOutline

b.      NuclearPwrPlnt

c.       JapanCities

d.      Roads

e.      NEJapanPrefectures

2)      Isolated the Fukushima Power Plant

3)      Created a Multi-ring Buffer using the ‘Multi-Ring Buffer’ in the Proximity tool

a.       Created layer in the Damage_Assessment Feature Class

4)      Clipped the Buffer so it was shown just on the land using the ‘Clip’ tool

5)      Clipped the roads layer and made them not so noticeable

6)      Ran the Select By Location Search Query to find the cities within 50 miles of the Fukushima Power Plant.

7)      Created labels for the cities and populations in Japan using [City]&vbnewline&[Pop]

8)      Created map with:

a.       Evacuation Zones

b.      Cities labeled

c.       Fukushima Power Plan labeled

d.      An inset map of Jap and the NE region

e.      With all essential map elements

9)      The putting together of the final map deliverable did not go as smoothly as usual.  The Data View worked perfectly but the Layout View did not.  I could not get the map to zoom to a view that I was satisfied with.  I tried several things:

a.       Closing and restarting ArcMap and computer

b.      Copying layers and starting a new map as suggested by one of the students (this made it so the Layout View did not show up at all

c.       I tried what one of the other students suggested, checking the projections – these were fine (but something to keep in mind for the future!)

d.      I gave up after several days of this and put together the map which has all the relevant information but does not look quite like I had wanted it to.

10)  Saved map as FukushimaEvacuationZones_cmb.mxd and exported as a jpg

Washington DC Crime Lab

This week we worked on statistics on crime in Washington, DC.  We created 3 maps and a bar graph with the following objectives:
- Create maps showing crime distribution in  Washington, DC
- Create graphs to demonstrate crime distribution
- Use Kernel Density to display crime clusters
- Geocode addresses in ArcMap to map police stations
- Create multiple dataframe maps in ArcMap to show various crime distributions across DC
- Use Field Calculator to calculate attribute table values
- Utilize Swipe Tool to allow crime cluster distributions to be displayed over census block data.












Process Summary Details
Step 2:
1)      Set the environments and predefined Projected Coordinate Systems to NAD 1983_Zone_18N, the current workspace as WashingtonDC\data and scratch workspace as \results\DC_results.gdb.
2)      Set the cell size to 73 and limited the analysis by setting the mask to ‘WashingtonDC’
3)      Added layers: ‘police_stations.csv’, WashingtonDC.shp and DC-streets
4)      Selected the geocode address ‘North America Geocode Service, saved the output layer as “police_stations” as a geodatabase feature class in the DC_results.gdb folder.
5)      Added excel file ‘DC_Jan2011.csv’ and added the coordinate system GCS_North_American_1983
6)      The scale is 1:160,978.
7)      There is no Object_ID Field
8)      Added the new table “Crime”
9)      Symbolized the police stations and made them much larger.
10)  Symbolized the DC_Streets layer.
11)  Summarized the ‘Offense’ data and saved as a dBASE table and changed the labels in the attribute table.
12)  Created graph
13)  I worked on the graph to make it look right because it was totally messed up, fields on top of eachother, font all out of order, etc
14)  Saved as Crime1.mxd and exported as jpg.


STEP 3: Produce a Map of Police Stations with Crime Proximity

1)      Set the environments and predefined Projected Coordinate Systems to NAD 1983_Zone_18N, the current workspace as WashingtonDC\data and scratch workspace as \results\DC_results.gdb.

2)      Set the cell size to 73 and limited the analysis by setting the mask to ‘WashingtonDC’

3)      Added the WashingtonDC boundary, police_stations, DCstreets and crime layers.

4)      Created a Multiple Ring Buffer around the police stations at 0.5, 1 and 2 miles.

5)      Performed a spatial join between buffer and crime.

6)      Added an Event field in Crime attribute table with a value as 1.

7)      Joined the Buffer and Crime layers

8)      Had an issue with the attribute table not being populated – many of the columns were set as “null”.  I deleted the laters and tried again with the same result.






9)      Used “joins and relates” tool to join the police_stations layer with the crime layer with an output name “pol_sta_crimes” – This did not work either.





10) 

11)  I could not get any further. I asked on the board for help and email Tanya.



STEP 4: Produce Density Maps of Burglaries, Homicide, and Sex Abuse Crimes



1)      Set the environments and predefined Projected Coordinate Systems to NAD 1983_Zone_18N, the current workspace as WashingtonDC\data and scratch workspace as \results\DC_results.gdb.

2)      Set the cell size to 73 and limited the analysis by setting the mask to ‘WashingtonDC’

3)      Added WashingtonDC and Crime layers.

4)      Ran a Selection Query for burglaries and crime.

5)      Used the Kernel Density on the crime layer and the population field Event. The Kernel Density actually seemed to work.

6)      Everything seems set as it should be but the results are not coming out right…this is he screen I am getting when I try to classify the crime density:

7)     



I don’t know what to do from here. Once again I am at the end of the assignment, I have worked nearly every hour available outside of work and I am not done because I keep having issue after issue.







 






Law Enforcement Participation Activity

Title of Article: The Incident Map Symbology Story
Original Article Written by: Lt, Chris Rogers, Kirkland Fire Department
Summary Written by: Catherine Bronson
Date Posted: June 21, 2012

            We all know that certain symbols are universal in a particular community or society.  We all know that a red sign at the end of the street means stop, a green light means go and a yellow triangle means caution.  Maps are the same way for those who need to use them.  We all know that N means north on a map.  First responders of all types need maps to negotiate where they are, where they are going and to make quick analysis of dangerous situations.  In order to do this, the maps they use need to have symbols that are easily recognizable.  These maps come in many forms, from paper to computer, some hand drawn and some computer generated.  Many of these first responders are now using GIS for construction of their maps and integrating their data.  The problem arises when different types of first responders use different symbols and different map forms but need to work together.  A specific incident may involve local organizations such as town police or fire, state organizations such as spill response units, state police and health and natural resources officials along with federal organizations like FEMA and the Red Cross.  They may all be using different forms of maps such as:
            Street Maps
            Emergency or building pre-plans
            Incident command and control applications
Damage assessment applications
Crisis management systems
And many others

Different responders have different terminology, priorities and data needed.  However, they all have the same goals of protection, fast response and mitigation and need to work together as a group to achieve these goals and therefore need consistent data.  According to Lt. Rogers, this is often called a Common Operating Picture.

            A common symbol known by various responders makes critical and timely decision making easier and clearer.  The problem arises that different organizations have different needs and different terminology.  An example of a success story for standardization of symbols is the National Wildfire Coordination Group.  This standardization of map symbology makes maps clearer and easier to understand.  However, this symbology does not work for other groups.  Another group under the US Department of Homeland Security attempted to create symbols included into four categories: Incident, Infrastructure, Sensors and Command Features.  There were issues with this set of symbols such as they were too graphical and hard to hand draw, some symbols were vague in their purpose due to a variety of definitions in various agencies and although over 200 symbols were created, there were still a lot missing.

As a solution to this problem was the creation of a group with the help of the NAPSG Foundation.  This group consists of people representing various first responder organization and requiring that the members have practical hands on experience as emergency responders and practical knowledge of mapping and GIS.  This group of responders were first presented with a challenge to create a map that showed the features: Hazards on an incident, Features that can help mitigate and incident and Mapping where command functions are located.  They then presented the map to the group.  At the in-person meeting they discussed each map and looked for common features.  What was decided at the meeting was the following requirements:

            A set of guidelines instead of standards
            Symbols that can be hand drawn
            Symbology that does not require a lot of training to understand
            Symbology must be usable in routine business of public safety agencies

Along with the acknowledgement that two types of maps are needed, a Tactical Map with a single problem emergency and a Strategic Map for a multiple problem emergency.   Below is an example of these types of symbols on a Strategic Map.

           

           
            This group that came together made a good start identifying the problem and the broad solutions to this problem.  They decided from the beginning that they did not wish to “re-invent the wheel” and to keep in mind that what they came up with needed to be flexible, scalable and consider all the hazards first responders may encounter from the smallest incident to a multi organizational large event.  I found this article very informative particularly with my involvement as support for some of these first responders and having taken FEMA courses.  I can see where there will be a broad benefit to the many organizations that need to come together to solve issues at hand and I see where there will need to be flexibility as different uses are and different priorities are met.
