Flow Line Mapping Module 10

Migration into the U.S. 2007

This lab required me to create a flow line map, like those nice and pretty ones you see on the news stations. To decided the how wide the lines should be I first choose how large the largest line would be and the rest are proportional to the first. When creating a flow line map the lines must not cover any of the map area. That is the toughest part of a map such as this. To add a little flare to the map I also made the slow lines 3D and added some shading to them.

Vector Analysis 2 Module 10

Desoto National Forest Possible Camping Sites

In this weeks lab I performed buffering, dissolve, and overlay. Buffers and overlay are two of the most common operations in GIS. A buffer is a area that is x amount of distance away from a map feature. With buffers you can choose different areas to buffer based on the map feature. You can also apply multiple buffers to the same feature to create a range ring around the feature.

With the above map I was given the vector data and requires to create buffers around the lakes, roads, and rivers. These features were then overlaid with the conservation area file. The conservation areas I am not allowed to camp in, the areas of the conservation area that overlapped my buffers were then removed from the map. The buffers that I created were 500 meters of a river, 300 meters of a road, and 150 meters of a lake. Since I was only given the vector data I added a base map that allowed to see that this campsite was was in the Desoto National Forest.

Isarithmic Mapping Module 9

This week I learned about Isarithmic Maps. Isarithmic maps are also known as contour maps or isopleth maps depict smooth continuous phenomena such as precipitation or elevation. Each line-bounded area on this type of map represents a region with the same value. For example, on an elevation map, each elevation line indicates an area at the listed elevation. 

On Both maps I added contour lines to help delineate were the values changed for each step. To create the contour lines I used the spatial analysis tool.

GIS Data Search Module 7 and 8

In this exercise, I comprehensively mapped one county in Florida. I acquired and format data, then create one or several maps to display those data. To bring all these feature into map projects, I explored both the LABINS,USGS,and FGDL web sites.  These sites contained all the data files I needed to complete this project.
