Week 10 - Geocoding

Enjoyed this assignment. Pretty straight foward and easy. I did not run into problems.

Week 9 - Vector Analysis II

This map is of the potential campground sits in a state forest. I did this by creating a buffer for the water and roads layer, and then setting an overlay in order to show the potential sites that were within 150 meters of a lake, 500 meters of a river and 300 meters of a road. The only issue I had with this assignment was to trying to not get the layers confused with one another.

Q1: Which tool did you use? Was there any noticeable difference between its results and the results from the instructions?

* The only tool that had the same layout as the union tool was the intersection tool. I gave me the same results without having to select and export the features that had a 1 in both the "insd_wbuf" and "insd_rbuf" fields.

Q2: Which tool did you use here? Why?

* I used the erase tool to exclude the conservation areas.

Q3: How many features are in this layer? What is the area of the largest feature? What is the area of the smallest feature?

* There were 79 features the layer.
* The largest feature was 1919 acres
* The smallest feature was 1 acre

Week - Data Editing in ArcGIS

This week I learned how to edit feature classes and shapefiles, digitize, features, snapping and topology. After working through the Virtual Campus I was given some datesets to edit and digitize. This was a fun assignment and came really easy.

Week 6 - Georeferencing Rasters

Module 5 - GIS Data Search

The purpose of this assignment was to collect the required data for my assigned county in Florida (Leon), and display them on one or more maps. I had to organize the layers to have the information show clearly. Between finding and downloading the proper data and creating the maps, this was the most challenging exercise yet but I did learn A LOT.

My first map has majority of the required data. I found the layers at Florida Geographic Data Library. I didn't have to change the projection on any of them as they all had the projection of Albers. It was fun using the clip tool. It came in very handy. If I had to give a tip on this assignment, I would say to be very organized when saving files.

This map is of the strategic habitat conservation areas. The map looked kind of bare, so I added the pictures.

I became very frustrated when looking for samples of the raster datasets but finally found my way through LABINS. Searching, downloading and clipping the required data took me the longest.

Map of Haiti

This image released by the U.S. Geological survey shows a shake map of the Haiti area. (U.S. Geological Survey/Associated Press).

I found this map on the CBCnews webiste (http://ww.cbc.ca/canada/montreal/story/2010/01/13/montreal-haiti-canada-support.html) which shows the instrumental intensity of the quake.

Week 4 - Projections

What you see are three projected layers used to compare area for a couple counties in Florida. By far, this assignment took me the longest. I got stuck on page 3, when asked to create a county boundary layer in the Florida State Plane North (HARN Feet), but once I got past the confusion (on my part), I was able to get through the rest of the assignment.

Coming up with how to display the square miles to show the comparison was a challenge. I decided to use a legend for each projection but could not figure out how to display both the county names and square miles. In each layer, I selected the counties needed for comparison and exported them into a separate layer. (I did this for all three projections). Since I could not figure out how to show the county names and square miles I figured out a work around.

Now, I don't know if I did this the correct way, but it was the only way I knew how. I wrote down the area for each county in each projection. When I was working on the symbology for the counties, I typed in the name and area for each value. It displayed the way I wanted it but again, I'm not sure if I did it the right way.
