Sentinel Satellite Imagery Download Scripts Sentinel Satellite Imagery Download Scripts
These Python scripts download Sentinel 1 & 2 imagery for the user defined study site areas of interest (AOI). The semi-automated script iterates through a systematic file structure, reads in geospatial bounds of AOIs for each study site, and accesses Copernicus Data Base Ecosystem using the European Space Agency's Open Earth Observation system. The script then queries this system for...
Code to analyze static occupancy of northwestern pond turtles (Actinemys marmorata) in timberland streams in the interior foothills of northern California Code to analyze static occupancy of northwestern pond turtles (Actinemys marmorata) in timberland streams in the interior foothills of northern California
The purpose of this study was to evaluate the distribution of northwestern pond turtles (Actinemys marmorata) and invasive American bullfrogs (Lithobates catesbeianus) in private timberland streams of interior northern California, USA. Fieldwork for the study occurred in 2021-2022 in Lassen, Plumas, Shasta, Tehama, and Trinity counties, California, and involved visual encounter surveys...
Code for a spatially interpolated integrated population model applied to simulations of spatially autocorrelated Greater Sage-Grouse (Centrocercus urophasianus) population data Code for a spatially interpolated integrated population model applied to simulations of spatially autocorrelated Greater Sage-Grouse (Centrocercus urophasianus) population data
This repository contains R code to: 1. Simulate spatially autocorrelated count and demographic data for 10 populations using mean and process variance estimates from a long-term (1938–2011), range-wide meta-analysis of Greater Sage-Grouse (Centrocercus urophasianus) population dynamics (Taylor et al., 2012). 2. Fit a spatially interpolated integrated population model (SIIPM) to the...
