In this tutorial, we show users how to mosaic and process overlapping Landsat scenes covering Las Vegas and the Grand Canyon on the Arizona-Nevada border. These scenes were carefully chosen based on their location and minimal cloud cover.

The multistater package can fit several types of multi-state models, including discrete-state discrete-time Hidden Markov Models using both maximum-likelihood and Bayesian approaches (HMMs) and discrete-state continuous-time state-space models (SSMs). The package was created to specify HMM and SSM designs that can be fit in both the frequentist and Bayesian paradigms within a single...

Separates a subduction zone earthquake catalog into three tectonic regions: upper plate, interface, and lower plate

Bats play crucial ecological roles, and provide valuable ecosystem services, yet many populations face serious threats from various ecological disturbances. The North American Bat Monitoring Program (NABat) aims to assess status and trends of bat populations, while developing innovative and community-driven conservation solutions using its unique data and technology infrastructure. To...

The North American Bat Monitoring Program: R Data Connection Package can be used to extract and upload data to the NABat Monitoring Program through the GQL API. This software is written as a wrapper around the NABat GQL API. Documentation for the database and API can be found at https://sciencebase.usgs.gov/. This code includes the ability to reformat NABat data, upload NABat data...

The North American Breeding Bird Survey (BBS) (https://www.pwrc.usgs.gov/bbs/) has counted birds annually for over fifty year. Survey 'routes' each consist of 50 'stops' (counts) placed along a line. Inter-stop distances can vary from route to route and from year to year, and precise locations of each stop are not typically recorded. This script quantifies uncertainty in BBS stop...

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...

This repository contains a R package with 2-level and 3-level occupancy models. The package also contains a set of tutorials designed to help users understand how to use and code occupancy models in Stan. The models include a statistical hierarchy that allows for multi-species modeling and estimating correlations among species. The models may also be used as a more general "random-effect...

This repository contains code to run an occupancy model for eDNA data from a gradient along the Illinois River collected in 2015.

This is stglib, the USGS Oceanographic Time-Series Processing Library. This Python software package contains code to process data from a variety of oceanographic instrumentation, consistent with the procedures of the USGS Coastal/Marine Hazards and Resources Program.

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.

pfdf: A Python library to facilitate post-wildfire debris-flow hazard assessments and research. This release provides the core functionality needed to implement operational hazard assessments. This includes tools to: * Analyze watersheds * Delineate and filter stream segment networks * Compute earth-system variables for stream segments in a network * Assess debris-flow probabilities...
