Week 7 & 8 Data Input, Editing and Data Search - Finding your ducks and keeping them in the row.......

     This midterm lab was designed to pull together our learning thus far.  Using an assigned Florida County, we were to determine the project requirements, obtain appropriate data, select a suitable graphic projection and display nine data formats using logical layering so that the final product(s) were visually compelling and easily to interpret.
     In addition to the five mandatory vector datasets and two raster datasets, I chose to use Invasive Plants and Wetlands for my additional Environmental dataset component.    All of the data was readily available either on Labins or FGDL with the exception of the hydrography information.  The hydrography data on FGDL, broken down by county, excluded Broward which was my assigned county.  I ended up using information from SFWMD; this contained hydrographic information for the entire state and took a bit of manipulation to eliminate the unwanted attributes within my clipped area.  Once I had obtained all the required data, I imported and projected (as needed) the data into an mxd file.  I used this file to determine how many maps I needed to create and the best approach to combining items within maps for good presentation.  I saved this file to my first map, removed unwanted data, symbolized remaining data and added required map elements.  I then saved two additional copies of this file so that I could remove the first set of data and add the data required for the current map.  I then symbolized the data, updated any source information and then moved on to my final map.  This process helped me to keep my map layouts identical and to reduce recreating the inset map and other essential elements; instead, I simply needed to perform minor editing.  I have attached my three maps and followed them with an outline of my process.
