The Mississippi Coastal Counties Elevation and Hydrography Map was made for the University of West Florida's Applications in GIS class project for Unit 3: Hurricane Analysis. Students are required to present a layout view map showing elevation, hydrography, and Bathymetry of the Mississippi Coast counties with places, types of water, barrier islands, and hydrography.

The area's high ground tops outs at 103 meters or 338 feet above sea level. Unfortunately, a small percentage of the coastal counties of Hancock, Harrison and Jackson, Mississippi sit at this elevation. Instead, elevations up to almost 8 meters or 26 feet below sea level dominate. As is common along all of the United States shorelines, densly populated communities are found in these low-lying areas. Also present is a vast hydrographic system with thousands of creeks, rivers and swamps.

Problems:

1. Following this Step:
12. Add water and symbolize it with Unique Values using the FTYPE field. For the sake of time, remove all values except Swamp/Marsh and symbolize with a distinct color or symbol. To remove values, right‐click on the type under .

I was not able to remove the values as indicated in this step. I'm not following how to right click and remove the value. Instead I created a new shape file of the wetlands and swamps using select by attribute.

2. The slanted raster image AND slanted map. I do not undersand how I would crop this so that the pic is a square rather than slanted. I tried cropping it, I tried changing scale and also tried to enable the clip image in data frame properties.


As usual feedback and suggestions are greatly appreciated! Thanks! Sue
