Projects in R

In Summer 2020 I took an -based GIS class. I wrote some code and created some cool stuff on the internet.

Building a project website

• Built a personal website to host the various projects completed throughout the course
• Learned to push website updates through github
• Practiced creating aesthetically pleasing web pages

COVID-19 Pandemic

• Analyzed COVID-19 data to see where in California cases were growing
• Created lists of counties that need to be watched by calculating per capita infection rates
• Practice generating tables using kable
• Created faceted bar plots to show case count changes over time in multiple states

Distances and the Border Zone

• Learned to use simple features objects to generate object boundaries, and then manipulate them to create spatial graphs.
• Learned to manipulate coordinate reference systems to according to what is needed for a calculation
• Calculated distances between geographic objects
• Generated maps shows hwo many people and what cities are located within certain geographic boundaries
• Quantified how many people live within the 100 mile border zone throughout the United States

Tesselations, Point-in-Polygon

• Created different tessellations inside the United states including hex, voronoi, square, and triangulation
• Simplified geometries to speed up calculation times
• Learned to write functions to expedite repetitive processes such as mapping tasks
• Used point-in-polygon counts to aggregate point data and figure out what the uses of different dams are

Rasters and Remote Sensing

• Practiced generating an area of interest from a CSV file by converting it into a simple features object, then creating a bounding box
• Created raster data that represented flood data and manipulated it to create a flood map
• Analyzed rasters using raster algebra to generate thresholds which could be used to find if a cell in the raster was considered to be flooded or not
• Performed a complete flood analysis using landsat imagery

Flood Risk in Mission Creek: Past, Present, Future

• Collected basin boundaries from USGS data and elevation data from the elevatr package.
• Performed a terrain analysis using by creating a Height Above Nearest Drainage raster
• Assessed the number of buildings impacted by a 2017 flood using the HAND raster
• Learned how to create a Flood Inundation Map library and animating it as a GIF to see how floods will effect an area
