GIS 5050 Module 5 - Geocoding

This week's lab assignment allowed us to work with .csv [comma separated values] files and import them into ArcGIS. The process was essentially taking a spreadsheet [non-graphical data] and importing it into ArcGIS, which superimposes the data onto a map [making it graphical data]. The dataset we used during the first portion of the lab utilized latitude and longitude coordinates to direct ArcGIS where to put the points on the map. 

The second part of this lab was taking non-graphical data that used street addresses instead of coordinates [latitude / longitude], applying an address locator to our map, and geocoding the dataset. This essentially went through every entry in our spreadsheet and mapped it out by looking the address up in the address locator that we applied earlier in the process. The end result was a web map that locates all schools within Manatee County, Florida [see above]. Out of personal preference, I pasted an exported map above, but this map can be viewed by clicking the link below [this link is public: it does not require the user to have an ArcGIS account]:

GIS 5050 Module 4: Vector Analysis

In this week's lab assignment, we worked on the manipulation of vector data. The first part dealt with creating geodatabases, storing feature classes within these geodatabases, and then using commands to select certain features according to their attributes. This portion of the assignment was very straightforward and the least time-consuming of the two.

In the second half of the lab, we continued learning about the manipulation of vector data using an array of functions, scripts, and tools that are located within the ArcGIS Toolbox. This part of the assignment gave us the opportunity to explore some of these tools on our own and create a map [shown above] with only a few given requirements. I did not have many problems with this lab; a majority of my time was spent on exploring the tools available and the numerous options associated with each.

The map above is a graphical representation of possible campsites that meet certain criteria at De Soto National Forest in Perry County, MS. The possible campsites were then color-coded by their size in Hectares. The locations of these campsites are based on distances from roads [using a fixed distance buffer of 300 meters], distances from lakes and rivers [using a variable distance buffer of 150 meters from lakes and 500 meters from rivers], and then the remaining areas that fell within the confines of conservation areas were subtracted from the possible campsite areas. As far as aesthetics are concerned, I chose a landscape orientation due to the fact that our main map frame is relatively square shaped, and I chose a dark red for the roads and shades of green for camp sites because these are standard colors used for these types of features, according to cartographic standards. Lastly, I chose to divide my campsites into four equal-interval divisions. These are some of the more important considerations I gave that led to this map's final appearance. Overall, I am completely satisfied with this lab assignment and the map that was produced as I worked through it.

 

GIS 5050 Module 3: Map Projections

On the second part of this week's lab assignment, we took a shapefile of all the counties located in the state of Florida and projected them with three different map projections [Albers, UTM Zone 16N, and Florida State Plane]. From this point, we calculated the different areas of four selected counties [in square miles] and compared the difference between each of the map projections. We then composed all the information on a map so it can be visually interpreted at a glance. Finally, we took raster images and defined a projection onto them, so they could be accurately placed on a map. This lab assignment was interesting, but it seems as if map projections are a subject that could be expanded on infinitely. I did not have any trouble following the steps in the lab assignment, so it seems that I spent the most amount of time compiling all the information into the map shown above and formatting it to an acceptable aesthetic level.
 

GIS 5050 Module 3 - Data Collection

 

This week's lab assignment was going out and collecting data of our choice and producing a map package, an online map, and [2] .KMZ files for Google Earth. As far as the software was concerned, the online portion of this assignment was the most confusing for me but I felt I had a decent grasp on it by the end of the day. We used the ArcGIS Field Maps app for collecting data out in the field and it was a surprisingly easy interface to navigate. As far as the data collection itself was concerned, I probably should have stuck with the suggested fire hydrants or stop signs. My subject of interest was survey monuments that have been registered by the Public Works department of Oklahoma City and these were not the easiest things to find. After a couple of failed attempts in some pretty questionable areas of the city, my son and I migrated our "scavenger hunt" to the outskirts of town and had considerably better luck. I have posted a screenshot of the ArcGIS Online map above [for those who do not have access to the program], and the link to the map is listed below:

GIS 5050 Module 2: Cartography

 This week's lab assignment was considerably longer than the first module, but it was an excellent opportunity to dive deeper into some of the abilities of ArcGIS. The objective was to create a map of Escambia County, FL that shows exactly where the University of West Florida is located. The map was also to provide reference using landmarks, such as cities, rivers, and interstates. It was also to include an inset map of the state of Florida that marked where Escambia County is located within the state. We learned many new features, such as clipping a shapefile to the boundaries of another shapefile [notice how the interstates and rivers stop at the border of Escambia County, FL], adjusting the scale of the maps, and specifically customizing the focus of a map frame to a particular layer's extent. Also, there were numerous map elements that were introduced [i.e. legend, scale bars, north arrows] and we were given the chance to explore their various settings to create a map that was individualized to our own personal artistic styles. Lastly, we explored each shapefiles' meta data which lists all sorts of information relevant to who collected the information, when the information was collected, and how the information has been revised and stored over the years. The files are very exhaustive in nature and will take some experience learning how to navigate through them, considering the amount of information that is included in them. Overall, I am pleased with the amount of learning that was involved in this cartography lab and I am very pleased with the aesthetic quality of the UWF Campus Location Map that was created during this assignment.
