It's Final Time!

This was final's week and boy what a week! We were assigned the task of finding out through a GIS analysis if the Bobwhite-Manatee transmission line placement was acceptable and feasible considering its proximity to homes, schools, daycare's, conservation lands and wetlands. To conduct this analysis we were required to define and quantify environmentally sensitive lands imposed by the transmission line, quantify homes within proximity of the transmission line, define schools and daycare's within proximity of the transmission line and to quantify length of the transmission line related to engineering cost.
This project took me about five days to complete. I was really nervous in the beginning, but as I started working through the project, I was really proud of myself from what I learned and retained from all the labs. It was time consuming and grueling, but I am confident that I succeeded. Below are the links to my power point presentation that includes my maps and analysis results and my slide-by-slide commentary. Enjoy!

Week 13: Georeferencing & ArcScene

This week's lab introduced us to Georeferencing. Georeferencing is a process where you tell the data where it belong's spatially. We used roads, buildings and Eagle Nests to correctly align with two raster images. This lab did not go so well for me. I had to start over about five different times when I go to the section of adding the second raster image. For some strange reason the second image was very distorted and warped each time I tried to add it or it was either really really tiny. After the fourth time of trying I deleted everything file from my Week 13 lab folder and re-downloaded them from the R drive, then it was like magic and everything appeared correctly. (operator error I'm sure). Either way I thought this lab was really fun because it allowed me to also create my first 3D map using ArcScene.

Week 12: Geocoding & Network Analysis

This week's lab introduced us to new tools in ArcGIS, Geocoding & Network Analysis. There were a lot of steps in this weeks lab that required a lot of understanding of navigating and running different processes to get the desired results. My map is a "geocode' of EMS locations in Lake County, FL. I also created a route based on three locations. This lab was not too difficult if you followed the instructions carefully and had a background knowledge of ArcMap. I am not sure though without more practice and without following the instructions if I could create the same results again.

Week 10: Vector Analysis 2

This week's lab taught us how to use various tools to create perform buffer analysis functions, use ArcPy to conduct multiple buffer analysis at one time, and to use the Overlay analysis function. The instructions were easy to follow and I understood what I was doing except when I go to step 5 number 18. I chose the Erase tool, but I am not sure if it was the correct one to use because the instructions said I should end up with four records and I ended up with six. This part was confusing to me. Feedback on what I did wrong would be very helpful for anyone who knows their's is correct.
Thanks!

Intro2GIS: Data Search

This week's lab required us to use the lessons learned from last week's lab by doing our own data search, download, and map projection. I downloaded my data from FGDL, LABINS.org, and NationalAtlas.org. The required layers to be shown on 1-3 maps was: county boundary, city/towns, public lands, roads, surface water. The environmental layers I chose was wetlands and invasive plants. We were also to download 1 Quad data set and a digital elevation model. The county I was assigned to was Madison, Florida. I re-projected all my vector datasets to Florida StatePlane. I left the raster sets with their original projections. I did this because I re-projected all of them to the Florida StatePlane and none of them would project correctly. After hours of trial and error I started fresh and used the original files downloaded and it worked properly. I created 3 separate maps to show all the details that I wanted to show.
1) Map of Madison Florida with all vector layers.
2) Map of Madison Florida with wetland layers.
3) Two dataframes of Madison Florida with DOQQ and DEM.

Intro2GIS: Projections Part 2

HOLY MOLY!!! What a lab. This lab was definitely the most challenging so far. Even though I have GIS and ArcMap experience, I still struggled. It took me about 9 hours to complete from start to finish. The most trouble I had was in the data part of downloading and trying to figure out how to get it from my local machine to the virtual desktop. Working on the final deliverable's was tough also mainly because I decided to pick Apalachicola and spent two hours trying to figure out why my projections were correct, but it was not showing up in Escambia County. LIGHT BULB! Apalachicola is not Escambia County, clearly I was not thinking. Finally I chose Perdido Bay and I was able to finish up the lab quite smoothly.

Intro2GIS: Projections Part 1

This week's lab was all about the projection! We learned about Albers, UTM, and State Plane. We learned how different projections can alter the results of a map such as location, area, and XY coordinates. We did a comparison from all three projections and created a map based on our results. We calculated the Geometry of the areas of 4 different counties and compared the results from each projection. You can see in the map below that the Albers and State Plane projection produced similar results, but with varying area sizes (closest results of the three). To do a true comparison you would need to chose projections that cover the most area.
