GIS 5007 Module 5 - Choropleth Mapping



This week's assignment challenged us to craft a compelling choropleth map. We focused on thoughtfully selecting a color scheme that effectively communicates the data's nuances. Beyond aesthetics, the task involved designing clear and informative legends and employing appropriate data classification methods. A key component was leveraging SQL programming to refine data presentation, allowing for targeted insights. Finally, we integrated proportional or graduated symbols to add another layer of visual information, all culminating in a cohesive and insightful map.



Leveraging the robust ArcPro ecosystem, I meticulously crafted my map, with only minor refinements applied to the SVG files. To enhance visual communication, I designed custom picture symbols using open-source icons sourced from https://www.svgrepo.com/. In a subtle yet impactful modification, I augmented the wine glass icon with a simple rectangle, lending it a fuller appearance. For the map's thematic resonance, I curated and refined a color palette using palleton.com. This involved selecting a vibrant spectrum of poppy and wine-reminiscent reds, juxtaposed against the grounding hues of bottle and leaf greens. To facilitate sharing and future use, I've compiled these custom color schemes and icons into a readily accessible stylepack.

To achieve precise data visualization, I extensively employed layer classes and the power of SQL. This allowed me to strategically filter and display information, excluding the area designated for my inset map. Furthermore, I utilized SQL to dynamically adjust the color shades of country labels, ensuring optimal legibility against the underlying map features. Recognizing the potential for visual clutter, I again leveraged SQL to selectively remove labels for smaller entities like Monaco and Vatican City. Given that Monaco's consumption patterns mirrored neighboring France, and Vatican City's generally aligned with Italy, these labels contributed minimally to the overall understanding of the map. This targeted application of SQL resulted in a cleaner and more focused visual narrative.

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 5100 Module 5 Damage Assessment

Image
 For this week's exercise we were tasked with conducting a structural damage assessment of a few block area impacted by Hurricane Sandy. We were asked to create a map of the path of Hurricane Sandy We were then given a very large raster data set with a very small project area to assess structural damage. Knowing something about Hurricane Sandy and the amount of damage, I immediately ruled out the possibility that there were any structures with no damage or only affected or sustained minor damage. I then narrowed in on determining which structures were destroyed and which sustained major damage. To complete the analysis of damage within a distance of the shoreline I used the created shoreline to create buffers of 0-100 m, 100-200m, and 200-300m. I used a basic join to derive counts for the following result

GIS 5100 M4

Image
 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...
