Decadal changes in stream fish communities and contemporary ecological drivers of species occupancy in two Appalachian U.S. National Parks 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
ARCHI: Automated Regional Correlation Analysis for Hydrologic Record Imputation, v1.0.0 ARCHI: Automated Regional Correlation Analysis for Hydrologic Record Imputation, v1.0.0
Welcome to Automated Regional Correlation Analysis for Hydrologic Record Imputation (ARCHI). ARCHI provides a workflow and interactive platform for regional-scale hydrologic record imputation. ARCHI allows users to aggregate, visualize, and impute records with irregular monitoring frequency at annual, seasonal, monthly, weekly, and daily timesteps. Missing data at “target” sites are...
Mosaicking and Clipping Landsat Cloud Optimized GeoTIFFs (COGs) 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 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...
Creating a Polygon GeoJSON AOI File 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.
