GIS 4035: Module 10 - Supervised Classification

Above is a map of Germantown, MD's Land Use. In this lab we learned how to further classify images in ERDAS by creating AOI layers that allow us to create our own signatures. By using the polygon and grow properties tool, we were able to pinpoint certain coordinates and areas and classify them in the image. After re-coding the signatures, we were left with 8 unique classifications that are displayed on the map. 

Module 9 - Unsupervised Classification

This week we learned how to perform an unsupervised classification in both ArcMap and ERDAS. We we were able to use tools and techniques such as iso cluster, maximum likelihood classification tool, swiping,  blending, flickering, and recoding. To demonstrate our new skills, we used an image of the UWF campus to classify 5 different area types.  The image above shows the breakdown of the 5 new categories and the percentage of acreage they cover in the land.

Module 8: Thermal & Multispectral Analysis

This week we continued to build on our photo analysis skills. The focus was thermal and multispectral analysis. We were able to create composite images in both ERDAS and Arcmap, interpret thermal infrared data, and we were able to continue working on band combinations. For this particular lab we had to choose one feature to display within the image provided. The bridge that decided to feature was displayed with a band of Red (Layer 6), Green (Layer 5), and Blue (Layer 4). You could notice the bridge going across the rivers. The small strip of pavement must provide enough thermal heat next to the water to create a great visual.

GIS 4035 Module 7: Multispectral Analysis

This week we learned several new techniques when it comes to multispectral analysis. We learned histograms, spectral characteristics, using the unique cursor, and using gray scale. We then tied all of our skills together to determine the best band combinations.

 The purpose of this lab was to determine 3 features using different band combinations.  Each map listed below has the explanation of each image and band combination. This lab was very interesting and I enjoyed learning how to change the image quality to display certain features.

Module 6: Spatial Enhancement

This weeks lab allowed us to get creative and start using the skills that we had learned. We were able to use newly acquired tools to make corrections to images that may have imperfections or errors. We were able to use both Erdas and Arcmap to utilize tools to enhance an image. One of the new tools that we learned how to use was the Fourier Transformation. We were able to use that to take the major striping errors out of the image. We also used high pass and low pass filters to make the image clearer. I was able to experiment a lot in this lab and learned many new skills that I will be able to utilize in the future.

Lab 5a: Intro to ERDAS Imagine and Digital Data 1

This week we began with some calculations of in relations to wavelength, frequency, and energy of EMR. I was also introduced to Erdass Imagine. The lab walked us through some of the basics of the program. We used the new program to create a subset image or map using a classified image of a section of forested lands in Washington State. I found some similarities of the program that made it easy to adjust. We then uploaded the subset image to ArcMap to complete our map. I found this week very interesting and I am looking forward to building on what I learned.

Lab 4: LU/LC Ground Truthing Analysis

This week we were able to continue off of last modules lab. Last week we worked on LU/LC classification. This week we had to check the accuracy of the lab using ground truthing analysis. After placing 30 points throughout the map, we used google maps to determine whether our initial analysis was true or false. Out of the 30 points, 27 of them were found to be true resulting in 90% accuracy. 

Lab 3: Land Use/Land Cover Classification Mapping

This week we were able to build on our photo interpretation skills by adding LU/LC classifications. I was able to recognize elements of the map and classify them by the LU/LC classification system. The Aerial photo of Pascagoula, MA shows just some of the elements of the area. I was able to recognize certain areas such as water, residential, and recreational land just by associations and certain details. The LU/LC map is split up into many different classifications and is color coded for easy yet simple display. 

GIS 4035 Module 2 Lab: Visual Interpretation

The first lab was a great way to introduce the fundamentals of photo interpretation. We were able to work on a couple of exercises to learn the basics of interpreting features on aerial photographs. The goal of the first exercise was to determine the differences of tones and textures. First we identified  5 tones in the photograph ranging from very light to very dark. Then we were able to identify 5 textures of the photograph ranging from very fine to very coarse. Identifying features was the goal of the second lab. We were able to identify features based on shape and size, shadows, patterns, and associations.

This was an awesome lab to get familiar with photo interpretation. Learning some of these new techniques were really eye opening. I never thought much of using shadows to determine objects in a photo before. I am looking forward to picking up new tricks along the way.

Week 1 - Own Your Map

Hello everyone! Glad to be back for another semester. I completed this lab during the "Intro to GIS" course. I re-posted my previous blog below.

"This weeks lab was a good way to build on what I learned last week. I was able to learn new ways to create a professional looking map. Week 2 has taught me me many skills such as to add inset maps, import cartographer details, and creating layers just to name a few.

I felt that this lab was a great way to improve my GIS skills. In this weeks lab, I was displaying where the UWF campus was located within Escambia County. Local highways and interstates are listed next to UWF.  I was able to add an inset map to show where Escambia County was located within Florda. I also added cartographer details, UWF logo, legend, north arrow, and a scale."

GIS4043/L Final Project - Bobwhite-Manatee Transmission Line

The final project consisted of gathering information for the proposed Bobwhite-Manatee transmission line. The 230kv line is a 25 mile transmission line that will pass through both Manatee and Sarasota counties. Our objectives were the following:

•How will the proposed line affect environmentally sensitive areas such as conservation lands and wetlands?

•How many homes would be within proximity of the proposed transmission line?

•Will any schools and day cares be affected?

•How many land parcels will be impacted by the proposed transmission line?   

•Determine the length

•Determine the cost

After gathering all of the information and data needed, I was able create multiple maps to show the results requested. I was able to clip a lot of the data into the study area and also into the preferred corridor to see what would be impacted by the transmission line. I provided a PowerPoint and transcript for a detailed presentation of the results.

Week 13 - Georefencing

Above I have my final products for week 13. In this lab we learned all about georeferencing, Root Means Square Errors, adding hyperlinks, and how to use ArcScene. The first map displays the UWF campus buildings, the campus road, and the eagles next protection buffer area. I highlighted the UWF campus gym and showcased the eagle nest and its buffer zone. To complete this map I had to use Georefence data by using control points to match the raster image to the known vector data. During this process I learned how to cheeck the RMSE to see how close i had it to the actual data, I learned how to create a hyperlink and add it to my ArcMap file so I can showcase a picture of the eagles nest. Also was able to use the multiple ring buffers tool to create a set buffer distance around the eagles nest. In the second map I was able to use the same map and create a 3D overlay. I thought this was pretty cool that I could set up my map to add the depth and detail to the UWF campus. This was a pretty cool lab and I was excited to learn the new tools/skills.

Week 12 - Geocoding and Network Analysis

This week we went over Geocoding and Network Analysis. This weeks objective was to create a map listing all of the EMS locations in Lake County, Florida. We had to create an address locator followed by the matching and re-matching of address for all of the EMS locations. We also had to choose an optimal route between three EMS locations. I felt that this was a very interesting lab and was cool to continue to learn what GIS skills can allow us to do. We also made a model builder for section 3 of the lab that showed where gas leaks were near public schools.

Week 10 - Vector Analysis 2

This week brought us two new tools to add to our skill set. Those two tools were buffer and overlay. We also got to try out ArcPy and write out scripts. We analyzed vector data using spatial queries to determine potential campground sites for a specified area. Between overlay options, erase tools, and other techniques we picked up, we were able to narrow down potential campground sites within certain parameters.

Week 7-8 - Data Search

For this weeks lab, we were assigned a county to showcase. I was given assigned Monroe County. I felt that Monroe county was a little more difficult to display due to the fact that Key West and the other islands make it a large piece of land to display.

After learning how to import data, I was able to use the FGDL,Labins, and National maps websites to find more data for this lab. I chose to display the elevation, surface water, and land cover on the map in the top left. In the bottom right I have Monroe cities, invasive plants, Monroe major roads, and state parks, I felt that this was more difficult to display due the the small area for the islands in the south part of the map.

Projections Part 2

Here is the final product of my Projections part 2 lab. This lab brought a lot of new aspects into ARCGis. We started out by learning that we can download new data on the FGDL.com and Labins.org websites. Citrix receiver was also introduced which made it very simple to transfer files from my PC to my eDesktop. We were introduced to Aerial, Topographic Quadrangles, and downloading additional shapefiles. We were able to continue working on our data tables and learned how to add x,y coordinates and upload them properly to our maps. Lastly, we were able to reproject our data.

Projections Part 1

This week in our lab, we were introduced to exploring projection systems. The three projections used in this lab were the following: Albers, UTM 16, and State Plane. By showcasing the three types of projections, we were able to notice a slight difference between the three. You have to compare closely to notice the difference. I calculated the area for the geometry and converted that information into a chart to display the actual difference.By looking at the chart, you can notice how the attributes are affected. This lab was a good way to learn how projections can alter a maps data.

Week 4 - Sharing Maps

http://arcg.is/2kJ7pDP

Hello everyone! As we are currently sitting a blizzard, I figured this would be a perfect time to blog. I felt that this weeks lab was pretty cool. All of the ways that we could create different files on different programs and have them interact was fun to do. 

I decided to showcase a top 10 list for stadiums in North America. We learned how to search internal and external data for basemaps, create excel files to be used for mapping, geocode using ArcGIS online, open our geocode in ArcGIS on our desktop, create maps for web publishing, create map packages, and how to open our maps on Google Earth. All of these techniques were fun to utilize. 

Week 3 - GIS Cartography

The map listed above showcases the elevation of Mexico. Showing elevation was one of the new skills that we had learned this week. Along with elevation we also learned how to explore data in Arc Catalog, dynamic text, signify statistics with colors, annotations, and more. I was able to continue to fine tune my cartographic skills and I feel that this lab taught me a lot. With these new skills we created 3 maps which consisted of the following:

- Elevation of Mexico
- Urban areas of Mexico
- Population of Mexico

I chose to upload the elevation map because I feel that you can visualize a lot. Using the stretched symbology scheme, I feel that the color choices really made it clear to determine the differences in elevation.

Own Your Map - Week 2 Lab

This weeks lab was a good way to build on what I learned last week. I was able to learn new ways to create a professional looking map. Week 2 has taught me me many skills such as to add inset maps, import cartographer details, and creating layers just to name a few.

I felt that this lab was a great way to improve my GIS skills. In this weeks lab, I was displaying where the UWF campus was located within Escambia County. Local highways and interstates are listed next to UWF.  I was able to add an inset map to show where Escambia County was located within Florda. I also added cartographer details, UWF logo, legend, north arrow, and a scale.

Hello and welcome to my first ever blog post!

In my first lab for GIS 4043/L, I was introduced to ArcGIS/ArcMap and created the country population map that is listed above. Following the instructions, I was able to familiarize myself with all of the features and tool bars that the software has to offer. This lab taught me how to add data, explore and sort through data, how to create a map, and how to add important items such as a legend, scale, north arrow, and text.

This was a perfect lab to learn all of the basics of the software. I am looking forward to building on what I learned this week.
