  In this lab, the Buffer and Overlay tool in ArcGIS Pro were used to create parameters of allowable camp sites within De Soto National Forest, Mississippi. This was done by selecting areas of land between water and roads as camp sites. Then conservation areas were placed into the map to define if there were overlaps between the camp sites and the conservation areas. Areas of intersections between the two were erased (using the Erase Tool) so the camping spots were no longer overlapping the conservation areas. The different colors of the areas represent the largest percentage of an area in hectares to be used as a possible camping spots.

  In this Lab, ERDAS Imagine was explored to view two types of satellite images (AVHRR and Landsat TM). Landsat TM aerial imagery was chosen to make a map of as it is much more detailed than AVHRR imagery. The image is a subset of a larger image that was in ERDAS, which was turned into a map in ArcGIS Pro. Specific areas can be pointed out and the size of each can be analyzed as well (i.e. hectares), as seen in the legend. Digital data can also be interpreted on ERDAS as well as different resolution types, which define how well an image can be seen or interpreted. 

This map depicts 4 counties being compared by 3 different mapping Projection Coordinate Systems. Projection coordinate systems all differ in how they measure areas on Earth. Albers is used for large regions or counties and is good for accurate area representation. UTM is more applicable for local or regional mapping, and specifically Zone 16N covers a specific section of the globe. The State Plane N Coordinate system is specifically designed for the United States and is used for local and regional mapping like UTM, but is more specific to each state. With these 3 coordinate systems, 4 different counties in Florida were projected. There are small differences in the square mileage, however State Plane N seems to be the most accurate. This seems to be due to how Florida has its own specific State Plane Zone (i.e East, West, South, North) depending on the county that is mapped. To add to this, since State Plane N is specific to the United States coordinate and the counties are being mappe...

  This map that was created in ArcGIS pro, showcases outlined regions of Pascagoula, Mississippi. These regions are given codes based on the aerial view of the image (i.e. collection of small houses is a residential area given the code number 11). The areas on this map were then compared to Google Earths street view and aerial imagery, to find whether the accuracy of the codes placed by the user were correct. Areas that have a green dot matched with Google Earth, and red dots were incorrect on this map compared to Google Earth.
