GIS4043: Vector Analysis 2

This week we worked on creating overlays and buffers. We created buffers using the buffer tool and ArcPy. The finished product is a map of possible sites that are within 300 meters of a road, 500 meters of a river, 150 meters of a lake, and excluded from all conservation areas.

GIS 3015: Isometric Mapping

This week we used data collected at weather stations in Georgia to create a isohyet map of Georgia's average annual Precipitation. We used the manual interpolation method to create the lines in Adobe Illustrator.

GIS3015: Proportional Symbols

For our Proportional Symbols Lab two maps were created, one showing the wine consumption in Europe, the other showing just the wine consumption in Western Europe. For our symbol size we used a mathematical scaling method to scale them to a proportional size that fit the map.

GIS4043: Data Search

In this weeks Data Search lab we worked on downloading data from online sources, data management, selecting graphic projections, and re-projecting data. This lab allowed for a lot of creative freedom both in selection of data and how that data was to be displayed. From the data required I created two maps which ended up having an “invasive plant theme”

The Required “Public Lands” data I downloaded was State Parks in Martin County. Then, the two required environmental layer I downloaded were 1) Invasive Plants and 2) Wetlands.

Because the invasive plants and wetlands made the map overwhelming and unreadable I did a definition query to limit my selections. The wetlands layer had water sources other than wetlands so I preformed a definition query to select “wetlands” in the “type” field. For invasive plants I selected only the species melaluca, since melaluca have a drastic effect on Florida’s wetlands. With this data I was able to create two maps containing all of the required data. The first showing melaleuca's encroachment on the State Parks in Martin County. The second showing the proximity of malaleuca to wetlands in Martin County. I really enjoyed this lab.

GIS 3015: Choropleth Mapping

The maps for this weeks lab show two different Choropleth Maps. The first map depicts a choropleth map with an appropriate color scheme depicting the population change by state in the United States between 1990-2000. One very helpful lesson I learned in this is how to change the data values (in this case the change in population growth values) to an more appropriate rounded number.

In the second map we averaged the population growth by region and used our own method to define classes. Because of the outliers I chose the natural breaks method to show more variation around the mean. I also manually drew a line in Adobe Illustrator to separate regions with the same color class value.

Projections Part 2: GIS4043

This week we worked on our Projections Part 2 lab creating a map that displays aerial raster data, topographic quads, vector shape files and xy data. First I chose a location of interest in Escambia County (the area I chose was an area I was doing oyster sampling in that week) I then downloaded the corresponding DOQQs from Labins.org. I then reprojected all of my data to NAD_1983, placed the roads shapefile and the excel x,y data over my DOQQs. As a reference I created a new data layer to show where my DOQQs lay in Escambia county.

Labeling: GIS3015

For our week 6 lab we focused on Typography using Adobe Illustrator. We used a map of Marathon in the Florida Keys to work on creating proper and well organized labels. The combination of land, water,and points of interest made this a good exercise. I found it particularly interesting because I use to work on Marathon Key.
