Electronic transport in materials is governed by a series of tensorial properties such as conductivity, Seebeck coefficient, and effective mass. These quantities are paramount to the understanding of materials in many fields from thermoelectrics to electronics and photovoltaics. Transport properties can be calculated from a material’s band structure using the Boltzmann transport theory framework. We present here the largest computational database of electronic transport properties based on a large set of 48,000 materials originating from the Materials Project database. Our results were obtained through the interpolation approach developed in the BoltzTraP software, assuming a constant relaxation time. We present the workflow to generate the data, the data validation procedure, and the database structure. Our aim is to target the large community of scientists developing materials selection strategies and performing studies involving transport properties.
This dataset describes the public transport networks of 25 cities across the world in multiple easy-to-use data formats. These data formats include network edge lists, temporal network event lists, SQLite databases, GeoJSON files, and General Transit Feed Specification (GTFS) compatible ZIP-files.
The source data for creating these networks has been published by public transport agencies according to the GTFS data format. To produce the network data extracts for each city, the original data have been curated for errors, filtered spatially and temporally and augmented with walking distances between public transport stops using data from OpenStreetMap.
Cities included in this dataset version: Adelaide, Belfast, Berlin, Bordeaux, Brisbane, Canberra, Detroit, Dublin, Grenoble, Helsinki, Kuopio, Lisbon, Luxembourg, Melbourne, Nantes, Palermo, Paris, Prague, Rennes, Rome, Sydney, Toulouse, Turku, Venice, and Winnipeg.
Contrary to the version 1.0 of this data set, this version (1.2) does not include the cities of Antofagasta and Athens, for which non-commercial usage of the data is not allowed.
Contrary to previous versions of the data set (1.0 and 1.2), in this version (1.2) the temporal filtering of the data has been slightly adapted, so that the daily and weekly data extracts cover all trips departing between from 03 AM on Monday to 03 AM on Tuesday (daily extract) or 03 AM of the Monday next week (weekly extract). Additionally, a temporal network extract covering a full week of operations has been added for each city.
Documentation of the data can be found in the Data Descriptor article published in Scientific Data: http://doi.org/10.1038/sdata.2018.89 When using this dataset, please cite also the above-mentioned paper.
The processes involved in bed-load sediment transport are complex and challenging to quantify. Field measurements provide insight and a chance to improve predictive methods. A comprehensive database contains more than 15,000 observations from nearly 500 bed-load sediment transport data sets. The database includes sample descriptions, discharge and transport data, channel and bankfull characteristics, surface and subsurface grain size distributions, and, where possible, stream classification descriptors. The database is freely available to the public. This database aims to provide useful data to researchers studying bed-load transport processes.
This dataset is an updated and improved version of the original. The original version, cited in the paper https://doi.org/10.1061/(ASCE)HY.1943-7900.0001221, was hosted at a byu.edu server that is no longer accessible. This version includes updates and improvements to the original, provided by Sagy Cohen.

The CO2 Transport Planning Database v3.0 is a geospatial resource, containing over 70 gigabytes of data representing critical considerations for the spatial routing of pipelines and transport of CO2, from source to sink. Considerations include state-specific legislation, land use requirements, existing infrastructure, and hazard prevention areas. Built to support strategic domestic energy transport planning and development, more than 60 layers of this database have been weighted (Weight fields) according to current legislation and pipeline construction recommendations. Weighted values range from zero to one, where zero represents potentially more acceptable areas for transport based on the various considerations, and a value of one represents areas that should be avoided. This geospatial database provides a baseline for the Smart CO2 Transport Planning Tool.

This database provides annual, quarterly and monthly estimates for energy use from commercial passenger, freight and general aviation flights. Energy use is determined by calculating the aviation fuel consumption for individual flights and then converting to terajoules. This is estimated for 186 countries by the OECD, based on a consistent methodology across countries. The estimates are compiled using Automatic Dependent Surveillance-Broadcast (ADS-B) flight data from the International Civil Aviation Organisation (ICAO).
This database corresponds with the air transport emissions database
The database provides energy use measures on a territory basis, which aligns with energy balances statistics (gross inland energy consumption); and on a residence basis, which is used to estimate the use of kerosene and jet fuels by air transport (H51 in the International Standard Industrial Classification of All Economic Activities, or ISIC) in the Physical Energy Flow Accounts (PEFA).
Seven components of these energy use measures can be selected from the ‘Energy use’ filter. In the tables, these are also shown with the letters A, B, C, D, E, F and G. The following aggregate measures of energy use are calculated as:
