This is the storm total precipitation (NTP) product. Each NEXRAD site reports the value for a different timespan. Basically, once a radar detects rain, it will begin to accumulate the rainfall in the NTP product. Once it stops raining for an hour, the value is reset to zero. Since all sites reset at different times, this service is updated every 5 minutes.

The data source is the National Oceanic and Atmospheric Administration (NOAA).

Air Monitoring stations within the Border Environmental Health Initiative. These are maintained by the Texas Commission on Environmental Quality (TCEQ).

In cooperation with the Texas Commission on Environmental Quality (TCEQ), the U.S. Geological Survey (USGS) collected and georeferenced more than 65,000 potential sources of contamination (PSOC) to ground-water supplies in Texas. These include, but are not limited to, landfills, trash piles, hazardous waste dispoal sites, waste injection wells, oil and gas wells, and certain types of businesses.

The Mexican data were not gathered for this purpose. Therefore in Mexico, the PSOCs were interpreted from the most current vector and topónimos (toponymy) data from the Instituto Nacional de Estadistica Geografia e Informatica (INEGI).

Land Use/Land Cover : Binational 1992

The NLCD 2001 is a multi-attributes, multi-source database that include a suite of data layers (30 meter resolution) staged as the standarized components intended for many applications -both nationally and locally. Specifically, the NLCD 2001 consists of: 1) calibrated Landsat imagery for three dates per path/row (acquired in early, peak and late growing season), 2) ancillary geospatial data, including 30m DEM and rerivatives (slope, aspect and topographic position index), 3) estimates of percent imperviousness and percent tree canopy per pixel, 4) land-cover classes derived from all images and ancillary data, 5) classification and prediction rules and confidence estimates for land cover and imperviousness and tree canopy data layer, 6) FGDC complaint metadata for the database.

7-Day composite of the MODIS satellite images: Contains bands 1-7 at 500m to create a normalized differenced vegetation index for the contiguous U.S. The composite continually refreshes on a weekly basis showing the NDVI of the last 7 days.

The 30 meter 1 arc second USGS National Elevation Dataset (NED) was harmonized with INEGI’s 30 meter Continuo de Elevaciones Mexicano(CEM) to create a seamless elevation model for the U.S.-Mexico Border region. In addition the USGS applied the NED filtering and smoothing algorithms to INEGI’s CEM to improve the dataset. The data are available from the USGS Seamless Data Distribution System for free download.

GTOPO60 Color Shaded Relief is a raster dataset derived by resampling the Global 30 Arc-Second Elevation Dataset (GTOPO30). The original U.S. Geological Survey (USGS) GTOPO30 dataset is a global raster Digital Elevation Model (DEM) with a horizontal grid spacing of 30 ardc seconds (approximately 1 kilometer).

GTOPO30 was derived from a variety of raster and vector sources. The data is expressed in geographic coordinates (latitude/longitude) and is referenced to the World Geodetic Survey system of 1984 (WGS84).

This raster dataset is an integrated mosaic of LIDAR data (post spacing of 3 meters) provided by the University of Texas Center for Space Research (UTCSR), 10 and 30 meter DEMs downloaded from the U.S. Geological Survey's (USGS) Seamless Data Distribution System (http://seamless.usgs.gov/), and 50 meter resolution elevation data from the Instituto Nacional de Estadistica, Geographica, e Informatica (INEGI).

This layer is only for IMS viewing purposes and is currently not downloadable.

The U.S. Geological Survey's (USGS) National Elevation Dataset (NED) has been developed by merging the highest-resolution, best quality elevation data available across the United States into a seamless raster format.

The seamless 1/3 arc second is derived from topographic quad based tiles of 10 meter resoltuion elevation data. The horizontal datum is NAD83, except for Alaska, which is NAD27. The vertical datum is NAVD88, except for Alaska, which is NAVD29.
