GIS5027: Week 2 LULC Classification and Ground Truthing

In this week's lab, we were to create a land use/land cover map from an aerial image of Pascagoula, Mississippi. I ran into technical difficulties and only partially mapped and sampled the project area (Map 1).

GIS 5027: Week 1 Visual Interpretation

 

In this week's lab, I began creating two maps visually identifying features using USGS aerial photographs. Various elements of interpretation were utilized.

 

Map 1. Identifying Texture and Tone

Textures and Tones were used to identify various features on Map 1. By looking at a range of tones, I could distinguish between dense and sparse vegetation and recognize surface differences. Texture variations helped differentiate between natural and cultural landscapes.

Map 2. Identifying Features

Map 2 ground features were identified by analyzing the shape and sizes of structures, utilizing shadows for clues, and recognizing patterns in both natural and cultural elements. Features were further identified through association, by looking at the context of the surrounding features. 

GIS 5050: Project Final

 

This week was the GIS505 Final. The final require us to take all of the skills we have arquired in the calss to data and apply them to a real-world study. The study was a Florida Power and Light Transmission Feasibility Study. We needed to create at least four maps highlighting different aspects of the study. 

The first map I chose to make was a Project Area my showing the location of the Study Area for the Transmission Line in Manatee and Sarasota Counties. 

FLP also needed to account for the impact to environmentally sensitive lands in the preferred corridor. I created a map displaying the conservation lands both within the study are and corridor. I also identified wetlands and uplands listed with the NWI that were impacted.

The next map I ran out of time in the making. FPL tracked the impact to residential areas in the preferred corridor and I got as far as making the buffer, but not digitizing the homes and analyzing the parcel data.

The project also tried to choose a rout t=for the Transmission line that would have the least impact of schools in the Study Area. For the next map, I used a geocoded layer from a previous lab to display the schools in Manatee County and repeated the geocoding process for schools in Sarasota County. No schools were impacted by the project.

GIS 5050: Week 6 Georeferencing and Editing

 This week, our project involved georeferencing images of the UWF campus. I worked with both aerial and survey images. Using control points, the images were georeferenced and I learned about the RSM error calculations, and how those errors help in evaluating the accuracy of the georeferencing. Next, I edited two types of shapefiles (line and polygon) to create a building and road from the georeferenced aerial images. In this map, you can see the three georeferenced images and the building and road I created. I also created a multi-distance buffer to display a conservation zone around an eagle's nest, that has a hyperlink to an image of the nest- making the map interactive to users. Overall, this map not only documents the current state of the campus but also aids in future planning by highlighting protected areas.
