The maps below represent the assignments in Chapter 15 and 16. These chapters had us editing and creating new data in Arc Map. I found this to be very interesting as it represented work that I have long wondered how to accomplish. These tools will be very valuable as I am adding new streams, construction sites, etc to maps that I will soon be creating.

The class on February 20th covered data sources and data entry. This included map scale, map generalization, and digitzing data. We also watched a brief demonstration on how to digitize data. This was especially interesting because I have needed this skill in the past to represent trails or creeks that were not displayed on the maps that I have. I think I will use this tool a great deal.

On Monday the 4th a good portion of class was spent discussing how maps are displayed. Specific topics such as latitude and longitude, shape of the earth, cartesian and spherical coordinates, and others were explored. The general topic for the study of this information is called Geodesy. Geodesy is study of shape and size of the earth.
