GIS 5935 Lab 2

 

To complete this exercise, I first created three shape files. I then digitized the intersection of 60 test points, 20 for ABQ Streets, 20 for Street Map USA, and 20 for reference derived from the provided aerial imagery. I used a batch process to add XY coordinates to all three shapefiles simultaneously. Rather than exporting to DBF, I selected the columns as needed and copied and pasted them into the correct spot in the workbook I set up in Google Sheets. You can access a template workbook with the formulas added here

GIS 5007 - About Me!

 Hi - I joined the GIS program in the fall of 2024 to formalize my GIS training after more than a decade of learning to use GIS independently. I'm an Archaeologist, with my BA and MA in Anthropology, and have worked for the UWF Archaeology Institute as a research associate since 2015. In the past few years, I have become actively involved in cemetery preservation and research. Something that you can read a little bit more about on my story map . Ultimately I am hoping to add GISP to my credentials list. Resetting a marker in AME Zion Cemetery Exploring Oakland Cemetery in Atlanta with the Association for Gravestone Studies Conference.

GIS 5103 Module 5 - Explore & Manipulate Data

Image
For this week we had to work with creating a new fGDB and then listing the feature classes to be copied to the new geodatabase using Python, each shapefile is then copied to the geodatabase  After iterating through each geodatabase a search cursor is initiated in order to produce the county seats within the cities shapefile along with their population Finally, a new dictionary called county seats is created and each of the county seats and their population is fed into the new dictionary and the new dictionary is printed

GIS 5100 M4

 For this week's exercise, we spent a considerable amount of time evaluating out-of-date elevation data, looking at the potential impact of storm surge data. This included comparing potential inundation models using LIDAR and USGS DEM-derived data. For the first exercise we were asked to compare Lidar data from New Jersey pre and post Hurricane Sandy. We were given several areas to asses and evaluate what has changed as well as looking at how the area has redeveloped based on a more recently derived buildings shapefile. We then turned our attention to the Tampa Bay Area where we looked at different methods of modeling storm surge and evaluated the predictive ability of each model. This included comparing counts of the types of buildings each building would see as flooded or not As well as comparing which models predicted a percentage of each type of building would be flooded to compare the accuracy of the different models Finally we created a map showing the agreement between the d...
