Landsat Compositing of the Ucayali Region in Peru Landsat Compositing of the Ucayali Region in Peru
The USGS User Services, in collaboration with a NASA project, created this compositing workflow that produces Landsat composites for the Ucayali region in Peru. The Ucayali region is located in the heart of the Peruvian Amazon and spans approximately 102,400 square kilometers (39,537 square miles), making it the largest region in the country. The Ucayali experiences significant cloud...
Mapping Snow Change through the Time Series Analysis of Landsat Data Mapping Snow Change through the Time Series Analysis of Landsat Data
This tutorial guides users on how to complete time series analysis in the cloud, with a focus on snow and glacial retreat at the South Cascade Glacier.
Using Checksums to Verify Downloads with Machine-to-Machine Using Checksums to Verify Downloads with Machine-to-Machine
In this tutorial users will learn how to verify downloaded files by generating checksums and comparing them to those provided by different endpoints in the M2M API.
Ecoflows body size analysis Ecoflows body size analysis
The code repository has been produced by the CONUS Ecological Flows project and contains scripts to run an analysis of fish body size relationships with flow regimes, functional traits, and land-use. This code can be run with the input dataset found from Woods (2025).
multi-species frog occupancy multi-species frog occupancy
Anurans (frogs and toads) were surveyed using aural call surveys across the upper Midwest, United States from 2003 to 2008, and again in 2024. This code analyzes these data (from the associated data releases) using a multi-species occupancy model with imperfect detection, species traits, and species associations. It tests for relationships between covariates, occupancy, and detection...
King Rail (Rallus elegans) occupancy trends in the Arkansas Delta King Rail (Rallus elegans) occupancy trends in the Arkansas Delta
This code cleans and analyzes historical King Rail (Rallus elegans) occurrence data in the Arkansas Delta to generate a multi-season spatial occupancy model. The data itself is publicly-available from Arkansas Game & Fish Commission.
