Data Access 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.

This tool allows the user to explore or download the National Gap terrestrial species habitat distribution models, ranges and the species models reports. These models cover the conterminous U.S. and were based on 2001 land cover conditions.

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

Groundwater flow and storage in the Edwards and Trinity aquifers are largely controlled by the geologic structure and hydrostratigraphy in the region. To help local agencies and stakeholders to more effectively manage the regional water resources, a better understanding of the spatial distribution of the geologic framework and hydrostratigraphic units of the aquifers is needed.

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.

The USGS Earth Resources Observation and Science (EROS) Center Science Processing Architecture (ESPA) On-Demand Interface is used to request processing and services for Landsat Science Products.

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 Whole Wildlife Toxicology Catalog is a compilation of websites containing toxicological information related to amphibians, reptiles, birds and mammals that may be of value to scientists, risk assessors, regulators and natural resource managers.

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.
