Pedestrian Evacuation Analyst software source code, v2.0.0

The Pedestrian Evacuation Analyst is an ArcGIS Pro toolbox that estimates how long it would take for someone to travel on foot out of a hazardous area that was threatened by a sudden event such as a tsunami, flash flood, or volcanic lahar. It takes into account the elevation changes and the different types of landcover that a person would encounter along the way.

spheroid90gp: Gaussian process emulation of vertical spheroidal elastic cavity models

The spheroid90gp software package computes surface displacements and cavity compressibility due to pressure or volume changes in buried vertical spheroidal elastic cavities. The software uses supervised machine learning techniques based on parallel partial Gaussian process emulators. The technique yields the accuracy of a numerical model at a computational cost comparable to that of some analytica

Global Animal Diel Activity Results

This ShinyApp provides users the ability to subset animal diel activity results by species, country, or project.

Caldera Collapse Earthquake Cycle Codes

This repository contains software files, codes, and data asociated with a publication on caldera collapse earthquake cycles.

Vignette detailing application of multi-scale occupancy models to Hoary bat, Lasiurus cinereus, in Montana, 2020 - 2022

This document serves as an open code book detailing application of a multi-scale occupancy model to bat acoustic data collected according to the North American Bat Monitoring Program (NABat) sampling design. In this document, we detail a complete analysis of acoustic data collected on Hoary bats in Montana between 2020 and 2022, including: examples of data cleaning and preparation for analysis, mo

GW-NDST software v 1.1.1

This version 1.1.1 release of the Groundwater Nitrate Decision Support Tool (GW-NDST) for Wisconsin supersedes the version 1.1.0 release. This version 1.1.1 release includes updated instructions in the readme file and fixes minor bugs.

MODFLOW 6: USGS Modular Hydrologic Model

MODFLOW is a popular open-source groundwater flow model distributed by the U.S. Geological Survey. 

Python Source Code for USGS Risk-Targeted Ground Motion Calculator

Python library and associate web services implementation that allows users to compute collapse risk-targeted design ground motions in accordance with the minimum design requirements of two commonly-used U.S. seismic provisions: the American Society of Civil Engineers "Minimum Design Loads and Associated Criteria for Buildings and Other Structures" (ASCE7) and American Association of State Highway

North Pacific Pelagic Seabird Database Visualization Tool (NPPSD_viz)

Code for R Shiny application to facilitate visualizing and subsetting the North Pacific Pelagic Seabird Database (NPPSD) using an interactive leaflet map. Database records can be filtered by higher taxonomy (bird vs. mammal observations), family, species, primary investigator, survey type date, and location. Users have the option to automatically zoom to the selected subset, or to zoom in to an ar

CO2assessment R package

The CO2assessment package provides R functions and a Shiny application for CO2 storage resource assessment using 2013 USGS National Assessment of Geologic Carbon Dioxide Storage Resources methodology. Tools to facilitate estimation of CO2 storage resources in geologic formations include volumetric and thermodynamic equations and Monte Carlo simulation. The set of input parameters define probabilit

Automated Walrus Haulout Cartography

This pyQGIS script and adjoining QGIS layout templates and style specification generate maps from satellite imagery and any derived geospatial outline data that are inventoried and cross-referenced in a tabular inventory file. The maps are intended for mangers, decision makers, and researchers to support real-time decision making and to provide a graphical record that may be publicly shared.

Code for multi-scale occupancy analysis of Temblor legless lizards, Anniella alexanderae

This repository contains code to fit Multi-scale Occupancy Models to survey data for Temblor legless lizards (Anniella alexanderae) This repository specifically contains code to reproduce analyses in: Rose, J.P., Camp, S.M., Sheikh, Z.N., Johnson, C.B., Lei, S.H., Napolitano, G.R., Schoenig, E.J., Macias, D.A., Jordan, A.C., and Halstead, B.J. 2024. Multi-scale occupancy surveys reveal temperatur
