Geospatial tool for mine waste volume calculations from remote sensing source code Geospatial tool for mine waste volume calculations from remote sensing source code
This geospatial tool is designed to calculate an estimated volume of mine waste using a polygon outline of the mine waste and elevation data obtained from remote sensing. The tool is developed to run as a toolbox in the ESRI ArcGIS Pro application. It calculates the volume using the geospatial data and a linear regression method described in the accompanying publication. This tool has...
Code repository for integrated occupancy model for single-visit semi-structured and single-visit time-removal sampling surveys Code repository for integrated occupancy model for single-visit semi-structured and single-visit time-removal sampling surveys
Multi-species structured surveys following specific sampling design are powerful tools for understanding species’ distributions and trends, but are not equally well-suited for surveying all species. Combining data collected under different protocols or sampling designs has the potential to boost sample size, extend geographic and environmental coverage, and improve model estimates...
Workflow and analysis for per-and polyfluoroalkyl substances (PFAS) in water and dragonfly larvae in United States protected areas Workflow and analysis for per-and polyfluoroalkyl substances (PFAS) in water and dragonfly larvae in United States protected areas
This code release provides the workflow and analysis code for a study that addresses the prevalence of PFAS on Federally protected lands in water and dragonfly larvae. This study quantifies the prevalence of PFAS in protected areas across the US, identifies ecologically relevant PFAS mixtures, and assesses the potential drivers of PFAS concentration in an effort to better understand...
Digital Shoreline Analysis System version 6.1 Digital Shoreline Analysis System version 6.1
The Digital Shoreline Analysis System (version 6) is a stand-alone desktop application that compliments a Geographic Information System (GIS). The DSAS software requires users to input a reference baseline and compilation of shoreline positions to generate measurement transects and shoreline intersections used to calculate rate-of-change statistics. DSAS provides an automated method for
MODFLOW Version 6.7.0 MODFLOW Version 6.7.0
MODFLOW 6 is an object-oriented program and framework developed to provide a platform for supporting multiple models and multiple types of models within the same simulation (Hughes and others, 2017; Langevin and others, 2024). This version of MODFLOW is labeled with a "6" because it is the sixth core version of MODFLOW to be released by the USGS (previous core versions were released in...
