This is my GIS 505 final project.

Objective number one was to define and quantify environmentally sensitive lands imposed by the transmission line.

To discover which conservation lands intersected with the preferred corridor, I ran a geoprocessing analysis on the intersecting features. From there, I opened the attribute table to figure out which land types would be imposed on by the corridor. I used summary statistics to calculate the total acreage.

First, I needed to find out where the wetlands intersected with the preferred corridor, so I ran an Analysis on which areas intersected of the two. After I extracted the intersections, I had to figure out which of the wetlands were wet (lacustrines & riverines) and dry (palustrines). To do so, I selected by attributes and created 2 new layers of the previously mentioned. I used Calculate Geometry to calculate the areas in acres. From there, I was able to calculate the total acreage using summary statistics. I had trouble with every aspect of this step after creating the 2 new layers/attribute tables, I especially struggled with the summary statistics for the sum of the acres.

Objective number two was to quantify homes within proximity of the transmission line.

First, I created a new shapefile for the homes inside the Preferred Corridor or 400 ft outside the Preferred Corridor. I needed to create a 400 ft buffer for the PC, and I did so using the Buffer tool. From there, I added text fields in the attribute table to distinguish between homes in the 400 ft buffer and homes inside the preferred corridor. I started to create points for the homes in the 400 ft corridor before moving on to the homes inside the preferred corridor, marking 2 or 1 in the text boxes according to where the homes fall. I was surprised how few homes they were, the preferred corridor path seems majority agricultural and industrial.

To find which parcels (Manatee/Sarasota) are inside the preferred corridor and inside the 400 ft buffer, first I ran an Intersect Analysis for each county/corridor combination I needed. I ran all my Intersect Analysis sequentially instead of jumping around like I had done for the first objective. I also took time to name each output feature class to something that makes sense. From there, I used the attribute table to count the values. This slide is an example for Sarasota, but I did the exact same thing for Manatee County.

Objective number three was to define schools within proximity of the transmission line.

To find the data for the schools that intersect the transmission line/transmission line buffer, I ran a geoprocessing intersection analysis for Manatee_Schools_Geocoded and Sarasota_Schools_Geocoded. No schools intersected the transmission line. I used my previously

geocoded Manatee Schools layer and geocoded Sarasota Schools using the FL Dept. of Education’s data and organizing it onto an Excel sheet. From there, I converted it to CSV and connected the table to my project, the geocoder matched all 67 schools in Sarasota County. From there, I created a map showing the schools in relation to the transmission line. I did not budget enough time to fulfil the requirement of  creating my own basemap.

Objective number four was to quantify length of the transmission line. I got 24.92 miles and used the measure tool and estimated the center.

And that concludes my GIS5050 final presentation.
