dem_getter Python tool for acquiring digital elevation models and derivatives from The National Map dem_getter Python tool for acquiring digital elevation models and derivatives from The National Map
This repository houses a set of Python tools to expedite the acquisition of 3DEP DEM data. These tools were designed to help geologists in the National Cooperative Geologic Mapping Program more efficiently produce high-resolution base maps and tailored derivative products that help identify and characterize geologic features. These derivatives include hillshades and slope maps, as well...

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...
