Selective Drainage Toolbox

This is release 1.0 of the Selective Drainage Toolbox. These tools are designed to be accessed using ArcGIS Desktop software (versions 9.3.1 to 10.4.1). The toolbox is composed of a collection of custom tools that implement geographic information system (GIS) techniques that can be used to identify and enforce drainage hydro features in digital elevation models- with a

12-digit hydrologic unit outlet (pour) points for the NHDPlus V2.1 WBD snapshot

This USGS data release consists of three datasets representing three derived outlets or "pour points" for each 12-digit hydrologic unit (HU12) in the Watershed Boundary Dataset (WBD) snapshot delivered with NHDPlus V2.1. The three related pour point locations, each delivered in a stand-alone dataset, are: "from" (fpp) and "to" (tpp) points that identify the locat

12-digit hydrologic unit outlet (pour) points for the NHDPlus V2.1 WBD snapshot: "vector" pour points (vpp)

This dataset represents one of three derived outlets or "pour points" for each 12-digit hydrologic unit (HU12) in the Watershed Boundary Dataset (WBD) snapshot delivered with NHDPlus V2.1. The three related pour point locations, each delivered in a stand-alone dataset, are: "from" (fpp) and "to" (tpp) points that identify the location where flow leaves the HU12 p

Pb isotope measurements of road dusts and background geologic materials in the Viburnum Trend resource extraction area of southeast Missouri (2011)

Abstract The isotopic composition of Pb in fugitive dust suspended by a vehicle from 13 unsurfaced roads in Missouri was measured to identify the source of Pb within an established long-term mining area. A three end member model using 207Pb/206Pb and concentration as tracers resulted in fugitive dust samples plotting in the mixing field of well characterized heterogeneous end members. End...

Alaska IfSAR Elevation Data

Radar data is being collected statewide for Alaska under direction of the USGS 3D Elevation Program (3DEP). The new data is vastly improving the accuracy and resolution of elevation data for the state, and is being collected using an airborne Interferometric Synthetic Aperture Radar (IfSAR) sensor. USGS and the State of Alaska maintain web-based status maps and download services.

Transportation Data

The transportation data theme consists of roads, airports, railroads, and features associated with the transport of people or commerce. The data includes the location, classification, name/route designator, for most roads, and address ranges. The data supports mapping and geographic analysis for applications for routing, traffic safety, congestion mitigation, and disaster planning and response...

Structures Data

USGS data portray selected structures data, including the location and characteristics of manmade facilities. Characteristics consist of a structure's physical form (footprint), function, name, location, and detailed information about the structure. The types of structures collected are largely determined by the needs of the disaster planning and response and homeland security organizations....
