Cartography & Analysis:
My GIS Portfolio
Click any image to see it in a pop-up in order to get a better look. I performed all data analysis and designed all of the maps presented in this portfolio. I am proud of the work I have produced thus far and plan to build a larger portfolio and gain more skills through a profession in GIS.

Analysis by Multi-Criteria Evaluation
Two Maps with different parameters to establish where new grocery stores are needed in Washington, DC census tracts. This analysis included obtaining data from various government departments, data normalization, and the creation of a multi-criteria evaluation.

Site Selection Using a Model Builder
A graphical modeler was employed to conduct all required actions at once. Thus, intermediate steps did not have to be saved, added, and then removed from the map. For this site-selection, I didn't know exactly which sites would meet all the criteria, so the model I created found them for me. Lastly, it can be re-run as many times as needed and can be edited if the criteria were to change.

JOSM Software
Trainings Led for YouthMappers Validation Hub
I led a number of live trainings on basic JOSM software, validation of data added to OpenStreetMaps, and advanced mapping techniques while I worked at the YouthMappers Validation Hub from February 2022 to May 2023. There were attendees from all over the world at each of these trainings. Links to three of my trainings, which remain on the YouthMappers youtube page, are underlined to the left.

Site Selection Using SQL in PGAdmin
All geoprocessing occurred outside of the QGIS interface and was instead conducted using SQL functions within PGAdmin. All SQL code can be viewed in the image below. Some functions utilized include: ST_Difference(), ST_Distance(), ST_Union, CROSS JOIN.

Environmental Conservation Predictions
This map involved using a multi-criteria evaluation where habitats with the highest combination of preferred criteria were delineated as suitable habitats.Paths between suitable habitats were determined using the criteria for the most optimal conditions possible and where the species had already been sighted.

Guidance Map
This required me to make vector polygons traced over satellite imagery for each of the landmarks. Additionally, I drew the walking path. The map is meant to be appropriate for tourist use, thus the less formal design.

Disaster Impact Analysis with Buffer and Clip Tools
A buffer around a disaster epicenter was created and then all relevant infrastructure was clipped so that only the points within the buffer were displayed.
