Agisoft Metashape Alignment Helper Version 1.0
The Alignment Helper is a GUI tool designed to be embedded in the Agisoft Metashape application. The Alignment Helper was written in support of a diver-based structure-from-motion data processing workflow and was built to facilitate proper alignment of Metashape models with the local grid coordinate system.
Code for the effect of myiasis on Eastern Box Turtle (Terrapene carolina carolina) body condition, movement, and habitat use at Camp Edwards
This software release contains one R script that reproduces all of the statistical analysis with objectives to (2) determine if myiasis affects Eastern Box Turtle body condition, (3) determine if myiasis affects Eastern Box Turtle shell temperature, (4) determine if myiasis affects Eastern Box Turtle habitat use, and (5) determine if myiasis affected turtles move shorter distances than noninfected
A Long Short Term Memory model for predicting daily lake ice cover changes in the Northern Hemisphere
This software release includes the python scripts and jupyter notebooks of collecting remote-sensed lake ice cover data, training & validating a lake ice model and visualizing the model output.
veg_sim: Modeling Greater sage-grouse habitat suitability 15-years post simulated fire event and sagebrush transplanting (2015-2030)
To assess the degree to which transplanting sagebrush (Artemisia spp.) could quickly restore former Greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) habitat and the strategies by which sage-grouse habitat restoration is best accomplished, we linked vegetation transitions with habitat selection models to evaluate habitat recovery. There are few data-driven approaches to ident
lasertram (Version 1.0.0)
This DOI is for the v1.0.0 release of the python library lasertram: a tool dedicated to the processing of time resolved analysis of laser ablation inductively coupled plasma mass spectrometry data
Decadal changes in stream fish communities and contemporary ecological drivers of species occupancy in two Appalachian U.S. National Parks
Although conserving fish biodiversity in lotic systems is challenging, protected areas can provide refuge from certain environmental stressors. In the Appalachian region, USA, the National Park Service manages Delaware Water Gap National Recreation Area (DEWA) and New River Gorge National Park & Preserve (NERI) which both contain abundant and diverse freshwater resources. To assess the effectivene
Mosaicking and Clipping Landsat Cloud Optimized GeoTIFFs (COGs)
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.
Querying the SpatioTemporal Asset Catalog API with GeoJSON Objects
The Landsat Spatio Temporal Asset Catalog (STAC) API enables spatial querying of the Landsat data archive by allowing users to define areas of interest (AOI) using various GeoJSON objects (points, lineStrings, polygons, or multipolygons). These objects facilitate spatial filtering based on specific geometric shapes. The STAC intersects query filter allows users to retrieve items within a defined g
Creating a Polygon GeoJSON AOI File
This quick guide shows users how to create a GeoJSON Area of Interest (AOI) file for querying in the Landsat SpatioTemporal Asset Catalog (STAC) API to access Landsat datasets.
Decoding and using the Landsat Pixel Quality Assessment Band for Masking
This work demonstrates how to utilize the Pixel QA band in Landsat data to mask out pixels affected by clouds and snow specifically in the Vancouver, Canada area. This process involves decoding the QA bit flag, creating a mask for cloud- or snow-affected pixels, and applying it to the imported data.
Querying the Landsat SpatioTemporal Asset Catalog through Metadata Filtering
The Landsat STAC catalog provides a versatile and user-friendly interface for accessing and exploring the USGS Landsat Archive. Understanding the characteristics and differences between the various Landsat data products is helpful for choosing suitable data for your research and applications. This tutorial focuses on filtering the Landsat STAC catalog for products based on various criteria, includ
Landsat STAC Direct Requester Pays Download
In this tutorial, we demonstrate the process of accessing Landsat data files through the STAC API and the AWS command-line tools, specifically the requester-pays functionality. Users can define their spatial and temporal parameters to query and download multiple Landsat data band files.
