This week's assignment asked us to look at the damage caused by Hurricane Katrina in three counties in Mississippi. There are 3 maps and a graph and a table that I have submitted here along with a Process Summary.
 |
| Deliverable #1- A map showing elevation/bathymetry of the Mississippi Coast counties with places, types of water, barrier islands, and hydrography. |
 |
| Deliverable #2 - A map of flooded land of the Mississippi Coast after Hurricane Katrina. |
 |
| Deliverable #3 - A map showing infrastructure and health facilities at risk from storm surge. |
 |
| Deliverable #4 - A bar graph showing percentage of total flooded land by land-cover type. |
 |
| Deliverable #5 - A table showing various land types that were flooded measured in acres and square miles. |
1. Set up my directory on S: Drive and copied over the necessary data from the R: drive
2. Answered Questions 1-4 (Returned to them at several points during the lab)
3. Opened ArcCatalog and previewed the data in both spatial and tabular form
4. Examined the Metadata to complete the chart as part of Q5
5. Organized my directory structure so that I have a S:\GIS4048-ApplicationsInGIS\W3-NaturalHazards-Hurricanes\Hurricanes\Project1\results path for my results
6. Created a new map document in ArcGIS and called it coast1
7. Created my Map Document Properties and set to relative paths.
8. Saved work
9. Set my coordinate system by importing the coordinate system from the land cover feature
10. Set up my Environment in Toolbox to handle current and scratch workspaces, Output Coordinate System, Raster Analysis settings and the mask to base the results on the 3 counties of interest
11. Added the elevation raster.
12. Answered Q6
13. Symbolized the color ramp for the Elevation. The tip about right clicking to see the names will come in handy at work and at my internship.
14. Added the Counties and set up the labels
15. Answered Q7
16. Added the Places, symbolized, and answered Q8
17. Added Islands to the map
18. Added swamps and rivers and symbolized appropriately.
19. This will be the base map that will give us a starting point for the rest of the assignment
20. Answered Q9 and 10
21. Saved my map (will com back to it later to get it ready to be a deliverable, as it is currently very busy)
22. Created Coast2.mxd
23. Documented the map, set the data frame properties, and set the environments just like the previous map
24. Turned on Spatial Analyst
25. Used the Math Tools in Spatial Analyst to convert meters to feet
26. Used the logical toolset to get the lands where elevation is less than or equal to 15 feet and saved it as flooded_land
27. Added Landcover
28. Reclassified Landcover using the Spatial Analyst reclassify tool.
29. Used Editor to label the reclassified data
30. Saved the reclassified data as a layer file
31. Added the counties and labeled them
32. Obtained the Statistics on the Count field
33. Answered Q12
34. Created a new field called “Percent” as float
35. Used the field calculator to set this new column to equal COUNT/1380797*100
36. Verified that this totaled to 100% using the statistics tool.
37. Saved my coast 2 document and graph. I will come back to prep it for delivery later
38. Created my coast3.mxd and set the description, coordinate system information, and environment
39. Added my infrastructure data to the MXD and symbolized appropriately.
40. Answered Q15 and Q16 ( I found a cool Spatial Analyst tool for this step called Spatial Analyst Tools | Extraction | "Extract Values to Points"
41. Started my coast4.mxd document
42. Documented the map, set the coordinate info, and set the environment settings.
43. Prepared my deliverables and Blog Post Entries.
