Sarah Haedrich - GitHub Homepage
My name is Sarah Haedrich, and I’m currently a student at Middlebury College graduating in February of 2020. I’m majoring in environmental studies and geography. For my last geography class, I chose to learn about OpenSource GIS softwares in GEOG323 with Professor Joe Holler. Over the course of the semester, we worked with QGIS, R Studio, SAGA, and PostgreSQL among other softwares. This blog showcases my work in the course, broken down by lab exercises.

Lab 01 & Lab02: QGIS Direction and Distance Model In lab 2, we worked in QGIS to create a model to calculate the direction and distance from polygons to a point. I used the model I created to look at median gross rent in comparison to distance and direction in El Paso Texas.

Lab 03: Hydrological Analysis of Mt. Kilimanjaro In lab 3, we worked in SAGA to create preform a hydrological analysis of Mt. Kilimanjaro using SRTM data from Earthdata Search. Our finished product is a channel network of the Mt. Kilimanjaro and the surrounding area.
Lab 04: Batch Scripts for Hydrological Analysis of Mt. Kilimanjaro In lab 4, we wrote batch scripts for the hydrological analysis we completed in lab 3 using both SRTM data and ASTER data downloaded from Earthdata Search. We also used error analysis
Lab 05 & Lab06: Vulnerability Analysis in Dar es Saalam In lab 5 and 6, we designed a vulnerability analysis in analyze Dar es Saalam, Tanzania. My partner and I decided to look at the number of schools per ward in Dar es Saalam using data from the Tanzania Resilience Academy.
Lab 07 & Lab08: Vulnerability Analysis in Malawi In Lab 07 & Lab 08, our class investigated at reproducibility and replicability by attempting to reproduce a vulnerability analysis in Malawi.
Lab09 & Lab10: Twitter Analysis in R Studio In Lab 09 & Lab 10, our class preformed a textual and spatial analysis of Twitter data during Hurricane Dorian across the Eastern United States.
