Chapter 4:

In Chapter 4, the focus is on mapping density and the various methods to achieve this. Density mapping is crucial for identifying patterns and groups within a given space, rather than analyzing individual data points. One approach discussed is mapping by defined areas, using dots to represent features. However, to avoid clutter, dots can be redistributed within specific areas, offering insights into which areas are more densely packed. Alternatively, density surface maps, utilizing raster cells, measure the number of features within a certain radius, assigning values and colors based on the concentration. The chapter also emphasizes the importance of choosing appropriate class ranges for natural breaks and quantile methods, which may seem exponential or arbitrary.

Chapter 5:

Chapter 5 delves into mapping areas, aiming to determine the best locations for specific purposes or understand the proximity of one element to another. Two main types of values, discrete and continuous, are assigned to features. Discrete features are clearly separated, while continuous features form a continuous path. The chapter explores methods to find what is within an area, such as drawing areas/features, selecting certain features, or overlaying areas/features. Each method has its applications, whether for firefighting strategies or legal considerations like property lines. The chapter highlights the versatility of mapping based on what’s happening inside an area, providing valuable insights for various applications.

Chapter 6:

Chapter 6 focuses on mapping things within a certain distance or time of a location, taking into account the complexity of factors like transportation infrastructure and terrain. Straight-line distance, buffer techniques, and the consideration of Earth’s curvature are discussed. The chapter introduces the concept of buffers around lines or shapes, offering flexibility for different classes of points/lines/shapes. The ability to determine distances across networks and analyze travel costs, especially for roads, adds a practical dimension to spatial analysis. The chapter also touches upon the simplicity of the algorithm for determining distance across networks, emphasizing the importance of accounting for real-world factors in mapping.

The introduction of standard classification schemes, such as natural breaks and standard deviation, adds complexity. The chapter also talks about the trade-off between accurate representation and generalization for pattern recognition, emphasizing the importance of dealing with outliers in the mapping process.

My name is Charlie Hornacek, I am a junior, studying environmental science and a minor in zoology. I enjoy cooking, playing football, and enjoying time with friends. I took this course as I thought it would be able to help have better understanding of then environment and give me good experience for later in my career as I would love to work as a park ranger or in the national parks. 

 As someone who is new to the GIS system , I found the information presented in  “Introducing the Identities of GIS”  to be useful in establishing a foundation for further learning. The various identities of GIS, including GIScience and GISystems, were explained in detail, making it easier for me to understand the different aspects of GIS technology. I also found it interesting to learn about the history of GIS and everything that was involved with its development. One of the more informative  sections for me was the discussion on the importance of visualization in GIS analysis. Understanding the relevance of visual display and its ability to help me reach conclusions about factors affecting different cases. I had never really considered how a visual representation of geographic information could significantly impact decision making. The distinction between GIScience and GISystems was also helpful in clarifying the roles of each in GIS analysis. Making this clear is helpful for someone stating out fresh trying to learn.

The First topic I was interested in was the population of gray wolves in the United States as I have done a research project over the group of wolves at the Columbus Zoo which gave me a better understanding and a valued interest in this animal. So I was wondering if you could track the progress of the animals in the wild as this is a recovering species in the United States.

The second topic I thought was interesting is invasive species as their is so many and is such a broad topic you have plants, animals, fungus I was wondering how gis could be used to maybe interpret the movements of these animals and use it to predict and stop the invasive species before they could get to a new environment.
