Data Analysis Tools

The USGS has developed a national inventory of significant topographic changes based on seamless multitemporal elevation data and land cover data. The National Elevation Dataset (NED) and the Shuttle Radar Topography Mission (SRTM) data form a unique pair of seamless elevation datasets that can be used to detect and analyze 20th century topographic surface changes in the United States.

To better identify the significant processes affecting our coastlines and how those processes create coastal change we have developed a Coupled Ocean – Atmosphere – Wave – Sediment Transport (COAWST) Modeling System, which is integrated by the Model Coupling Toolkit to exchange data fields between the ocean model ROMS, the atmosphere model WRF, the wave model SWAN, and the sedime

In cooperation with the City of Houston, USGS collects, processes, and interprets water-quality, streamflow, and reservoir water elevation and capacity data. These data are collected to better understand the effects of urbanization in Lake Houston, a drinking water reservoir in Houston, Texas.

This tool produces shapefiles that contain the delineated basins, basin characteristics, and flow statistics for multiple sites requested at once by users. Before this tool can be used, the the points of interest will likely need to be edited in GIS so that they are coincident with the stream grid used by StreamStats for delineations and saved to a shapefile.

The Water On-the-Go app has been discontinued. You can view gages near your location using the National Water Dashboard. “Water On-the-Go” was a map-based web application to give people easy access to current conditions in streams across Texas. It was developed to help raise water awareness during floods and normal conditions.

The Coastal National Elevation Database (CoNED) Project Viewer is a portal to the topobathymetric models created with the expertise of the expertise of the U.S. Geological Survey Earth Resources Observation and Science (EROS) Center near Sioux Falls, SD.

The Health-Based Screening Levels for Evaluating Water-Quality Data searchable online database provides Health-Based Screening Levels (HBSLs) for hundreds of chemicals, including pesticides and degradates. HBSLs are non-enforceable benchmark concentrations of contaminants in water. These screening levels supplement federal drinking-water standards and guidelines.

The Land Treatment Exploration Tool is designed for resource managers to use when planning land treatments. The tool provides useful summaries of environmental characteristics of planned treatment areas and facilitates adaptive management practices by comparing those characteristics to other similar treatments within a specified distance or area of interest. Provisional Software.

How do we get ready for big earthquakes in populated areas? An important first step is to learn what a big earthquake could be like. These pages summarize the main patterns — the earthquake effects that show up again and again. Here, urban is shorthand for “cities, towns, and suburbs”.

Oceanographic time-series measurements made by the U.S. Geological Survey between 1975 and the present as part of research programs. The data were collected to address specific research questions and were primarily collected over durations less than a year, using stationary platforms, with sensors near the sea floor. These data have been used to study of ocean dynamics and to validate ocean models

The Greater Sage-grouse annotated bibliography was developed as a synthesis of scientific information developed since the records of decision were completed for 2015 Bureau of Land Management/U.S. Department of Agriculture plan amendments for Greater Sage-grouse. This site provides an interactive, searchable interface to summaries of the scientific literature.
