U.S. Census Bureau provides a 2020 TIGER/Line shapefile of topological face polygons for Baker County, Georgia. This dataset contains the areal primitives used to build all Census geographic areas, with each face encoded with key geographic area codes for data tabulation.
Topological face polygons from the U.S. Census Bureau's 2020 TIGER/Line database contain key geographic area codes for all Census-tabulated areas. Each polygon face has a unique topological face identifier (TFID) and can be combined with other shapefiles to build seamless national coverage. The data is designed to enable the construction of geographic area geometries by dissolving faces on specific codes.
U.S. Census Bureau's TIGER/Line Shapefile provides the 2022 road network for Eastland County, Texas. It includes all road and path features from the national Master Address File/TIGER Database, such as primary roads, city streets, and pedestrian trails. The data is extracted from a seamless national geographic database designed to stand alone or be combined for national coverage.
2022 data from the U.S. Census Bureau's MAF/TIGER Database provides a complete extract of road and path features for Grimes County, Texas. The shapefile includes all primary, secondary, local, rural, and pedestrian paths, designed to stand alone or be combined with other county files.
2022 data from the U.S. Census Bureau's TIGER/Line system provides polygon topological primitives for San Diego County, CA. Each face includes unique identifiers and key geographic area codes for Census tabulation. The dataset is designed to stand alone or be combined with other shapefiles for national coverage.
Carroll County, Iowa's 2022 TIGER/Line Feature Names Relationship File links geographic features to their names and associated address ranges. It is part of the U.S. Census Bureau's national MAF/TIGER Database, designed for integration with other shapefiles like EDGES.shp and ADDR.dbf. The file includes attributes for linking features using identifiers like ARID, LINEARID, and TLID.
Owsley County, Kentucky topological face polygons from the 2022 TIGER/Line database. The dataset contains areal primitives that form a seamless national map, each with unique identifiers and key geographic area codes for Census tabulation. It is an extract from the U.S. Census Bureau's MAF/TIGER Database.
Topological polygon shapefile from the 2020 U.S. Census Bureau's TIGER/Line database for Benton County, Mississippi. Each face polygon includes key geographic area codes used for Census data tabulation. The data is designed to stand alone or be combined with other county files to create a seamless national map.
McLennan County, Texas, contains polygon data for topological faces, which are areal primitives from the Census Bureau's MAF/TIGER Database. Each face includes a unique identifier (TFID) and key geographic area codes for 2020 Census and survey tabulations. The dataset is part of the 2022 TIGER/Line series and can be combined with other county files for national coverage.
2022 data from the U.S. Census Bureau's TIGER/Line system provides polygon topological primitives for Scott County, Minnesota. Each face includes key geographic area codes for all areas used in Census 2020 and annual surveys, enabling the construction of various geographic boundaries.
The TIGER/Line Feature Names Relationship File for Person County, North Carolina, in 2022 links geographic features to their names and associated address ranges. It is an extract from the U.S. Census Bureau's national MAF/TIGER Database, designed to stand alone or be combined with other files for broader coverage. The specific row and column counts are not provided in the input.
Aerodynamic flow field and summary coefficients for 8,996 airfoil shapes, computed using the HAM2D CFD model. The dataset provides simulations at two angles of attack (4 and 12 degrees) for a benchmark in AI/ML tool testing. It was generated in February 2023 using the Bridges-2 supercomputing system.
U.S. Census Bureau TIGER/Line shapefile provides linear topological primitives for San Francisco County, CA. The All Lines Shapefile contains geometry and attributes for features like roads, railroads, and hydrography, each with a unique TLID identifier. This extract is part of a seamless national database designed to stand alone or be combined.
Over 250,000 Computational Fluid Dynamics simulations provide aerodynamic data for 1,830 airfoil shapes. The dataset includes flow field values like momentum and vorticity, plus summary coefficients of lift, drag, and momentum, computed across 25 angles of attack and three Reynolds numbers. It was generated in 2023 using the HAM2D RANS solver as a benchmark for AI/ML tools in wind energy research.
A dataset of math word problems paired with step-by-step solutions, hosted on Hugging Face by author peiyi9979. The dataset was last updated on January 3, 2024. Each instance contains fields for the problem text, a label, and a task type.
Nièvre department in France contains areas exposed to natural hazards, as defined by the Natural Flood Risk Prevention Plan (PPRi). The dataset, published by the Bureau de Recherches Géologiques et Minières, delineates zones based on hazard intensity and probability of occurrence, including areas behind protective structures. It was last updated on December 7, 2023.
A 2023 data repository from the National Institute of Standards and Technology contains three integrated studies on nickel-based alloy 718 (IN718) manufactured via laser powder bed fusion. The work investigates the influence of laser energy density and build orientation on grain structures, pore structures, surface roughness, high-cycle fatigue life, and tensile properties in the as-built condition. Data includes measurements from 25 distinct processing parameter sets and is organized into sub-folders with multiple file formats.
Registration status for each Licensed Home Care Services Agency (LHCSA) in New York State for the 2023 calendar year. The New York State Department of Health maintains this dataset, which was last updated in November 2023. Each agency must register annually to legally provide services and bill for care.
27 years of near-global lightning flash rate data are compiled from three NASA low Earth orbit sensors: the Optical Transient Detector (OTD), the TRMM Lightning Imaging Sensor (LIS), and the ISS LIS. The dataset provides annual mean flash rates on a 0.1-degree grid, processed by the GHRC_DAAC with observations spanning from April 1995 to November 2023. It uses an updated compilation approach informed by post-mission data volume and sensor efficiency insights.
Alaskan boreal forest and coastal tundra sites provide vertical profiles of snow reflectance and specific surface area (SSA). Data were collected as part of the NASA SnowEx 2023 field campaign using an A2 Photonic Sensor IceCube. NSIDC_CPRD published the processed snow-off data on October 28, 2023.
