Welcome to the Parker Group's public repository overview. Below is a curated list of our public projects, organized by category.
- Air Raids in Yemen: Dataset compiled from various sources detailing air raids in Yemen.
- Leishmaniasis and Conflict: Dataset for the study on the association between conflict, environmental factors, and leishmaniasis incidence.
- Dire Dawa Seroprevalence Survey: Data repository for a seroprevalence survey conducted in Dire Dawa in 2024.
- Nighttime Lights and Conflict: Data and code assessing the use of nighttime lights as a tool for measuring conflict in Yemen and Ukraine.
- Variogram Basics Part 1: An introduction to variograms and spatial dependence.
- Spatial Correlograms Part 1: An introduction to measuring spatial dependence through correlograms. Compare to the variogram.
- Spatial Dependence Part 2: Apply correlograms and variograms to your own CSV data (with included dummy datasets). Demonstrates binning, Moran’s I, Geary’s C, and semivariograms side by side.
- Standard Deviational Ellipse (SDE) Tool: Computes 1, 2, and 3 SD ellipses for spatial point patterns by group, including weighted options and orientation via the covariance matrix. Implements √2 scaling based on Yuill (1971) DOI: 10.2307/490885.
- Earth Observation How-To: Practical step-by-step guides for EO workflows (NOAA ISD weather station data, ERA5 climate reanalysis, QGIS zonal statistics, etc.).
- Kinshasa Earth Observation Data and Analysis: Case study repository with end-to-end EO data processing and visualization for Kinshasa, DRC.
- Parker Group Webpage: The official Parker Group website.
- Lab Values & Expectations – Our guiding principles and expectations.
- Lab meeting schedule - Our schedule of speakers/readings for lab meetings.
We use generalized additive models (GAMs) a lot in our work — here’s a rare sighting of a GAM in the wild. [spotted somewhere around here: 34.6272, -115.9901]
