Alligator snapping turtle population simulation model developed in support of the Species Status Assessment Alligator snapping turtle population simulation model developed in support of the Species Status Assessment
This software release contains six R scripts that comprise a population viability analysis for the alligator snapping turtle (Macrochelys temminckii). To predict numbers of M. temminckii in the future, we constructed a female-only, stage-structured matrix projection model. We incorporated multiple types of uncertainty into the simulation model, including parametric uncertainty and...
Introduction to Landsat STAC Tutorial Introduction to Landsat STAC Tutorial
The Spatio Temporal Asset Catalog (STAC) family of specifications standardizes the way geospatial metadata is structured to better enable data querying. The United States Geological Survey (USGS) utilizes STAC to better enable the search and discovery of Landsat data by providing STAC metadata for every Landsat data product accessible through the Amazon Web Services (AWS) cloud platform...
Geofetch Geofetch
geofetch is an R package that provides an interface for interacting with online rasters. By making use of drivers from the Geospatial Data Abstraction Library (GDAL) for accessing online rasters, it facilitates efficient raster operations by only retrieving data that falls in the user-specified area of interest. The package is built so that adding interfaces to new datasets is simple...

This repository contains code to run an occupancy model for eDNA data from a gradient along the Illinois River collected in 2015.
A ‘How-to’ Guide for Estimating Animal Diel Activity Using Hierarchical Models A ‘How-to’ Guide for Estimating Animal Diel Activity Using Hierarchical Models
We provide R Markdown files that are built by Bookdown to create a tutorial (HTML) that contains step-by-step examples on how to use trigonometric and cyclic cubic spline hierarchical models to analyze animal diel activity patterns from time-stamped data.
