1. MATERIALS AND METHODS DESCRIPTION OF WORK The Louisiana map layers for this project from the ESRI Tiger/Line 2000 web site at http://www.esri.com/data/download/census2000_tigerline/index.html. These consisted of the layer for all the counties (parishes) for the state of Louisiana. Through extracting the ee.file Arc GIs Allowed me to make the boundaries of Louisiana a selectable and editable layer.http://www.esri.com/data/download/census2000_tigerline/index.html The primary data source of this project is the Louisiana’s Coast Web site at http://www.lacoast.gov/. I extracted the information pertaining to the Louisiana’s Coast and inserted the information into excel documents. Instead of transforming the data into a database file for Arc GIS can recongnize it and possibly join it to the Louisiana shapefile layer, I edit the information in the attribute table that was presently in the Louisiana layer. As in tutorial 5, the excel program 2007 version doesn’t work with the GIS application as well as the 1997-2003 version of the excel program. Consequently, the GIS tutorial book was published during the time of the older version of excel, and don’t included tips about compatibility with excel 2007. Actually, I attempted this process but couldn’t transform the excel book to a database file. The process wasn’t even an option as in excel 2003. Using the excel function properties I calculated the total land loss and water gained and saved that new inclusive information into separate excel document. To insert the information into the tables in the map, I added another field, and using the editing process available in Arc GIS I manually added the necessary information in two different mapping documents. I also provided a buffer along the coast of Louisiana. This process was achieved by first digiting and sketching a polyline that fit the coast line and using the analyzing tools to add the buffer. http://www.lacoast.gov/ INTRODUCTION / BACKGROUND n wake of Hurricane Katrina, devastation was eminent. As on the new and television the people, business and industries were greatly affected by this catastrophe; however, no one is mentioning the effects of the hurricane on Louisiana’s coastal land. It is true that the people and businesses are returning to Southeastern Louisiana, but some effects experienced by the coastline are irreversible and permanent. In addition to the major impact during the considerably short time period of the storm, Louisiana was already on pace of losing its wetlands. Tracking the loss of land will help prevent future loss of Louisiana’s coastline. A database can be used as such a tracking device.

In the hyperlinks of the mapping documents areas such as Chandeleurs islands, part of Saint Bernard parish, were completely decimated by some of the storm surges. One notable problem in recognizing the correct areas for the coastal depletion was the name of some of the areas. For example, Calcasieu, an area of land loss after Katrina, is a name of a parish in Louisiana but it is far from Louisiana’s southeastern coast. When I reviewed the photos on the Louisiana Coast website, I couldn’t find any pictorial data on Calcasieu parish. It wasn’t until looking at the Plaquemines coast closer that I discovered that the name Calcasieu, used in the data I collected was the actual name of a basin along the gulf coast. Calcasieu along with other basins that form Plaquemines parish coast line was the most affected by Katrina. I looked at some of the storm tracking documents and discovered that area was directly in the pathway of Katrina; thus, suffering the most damage. REFERENCES [1] Lo & Yeung, Albert.
