Data Catalog

The Federal Transit Administration's National Transit Database (NTD) records the financial, operating and asset condition of transit systems. After data reporting was required by Congress in 1974, the NTD was set up to be the repository of data about the financial, operating and asset conditions of American transit systems. The NTD is designed to support local, state and regional planning efforts and help governments and other decision-makers make multi-year comparisons and perform trend analyses. It contains a wealth of information such as agency funding sources, inventories of vehicles and maintenance facilities, safety event reports, measures of transit service provided and consumed, and data on transit employees. Those receiving funding from the Urbanized Area Formula Program (5307) or Rural Formula Program (5311) – are required to submit data to the NTD in uniform categories. More than 660 transit providers report to the NTD through the Internet-based system.

The Environmental Protection Agency (EPA)'s Enforcement and Compliance History Online (ECHO) website can be used to search for facilities in your community to assess their compliance with environmental regulations. You can use ECHO to search for facilities, investigate pollution sources, search for EPA enforcement cases, examine and create enforcement-related maps, and analyze trends in compliance and enforcement data.

The State Ambulatory Surgery and Services Databases (SASD) are State-specific files that include data for ambulatory surgery and other outpatient services from hospital-owned facilities. In addition, some States provide ambulatory surgery and outpatient services from nonhospital-owned facilities. The uniform format of the SASD helps facilitate cross-State comparisons. The SASD are well suited for research that requires complete enumeration of hospital-based ambulatory surgeries within geographic areas or States.

The largest all-payer ambulatory surgery database in the United States, the Nationwide Ambulatory Surgery Sample (NASS) produces national estimates of major ambulatory surgery encounters in hospital-owned facilities. The NASS contains clinical and resource-use information that is included in a typical hospital-owned facility record, including patient characteristics, clinical diagnostic and surgical procedure codes, disposition of patients, total charges, expected source of payment, and facility characteristics.

This data collection documents all cases of military intervention across international boundaries by regular armed forces of independent states in the regions of Europe, the Americas (and Caribbean), Asia and the Pacific, Sub-Saharan Africa, and the Middle East/North Africa. Military interventions are defined operationally in this collection as the movement of regular troops or forces (airborne, seaborne, shelling, etc.) of one country into the territory or territorial waters of another country, or forceful military action by troops already stationed by one country inside another, in the context of some political issue or dispute. The study seeks to identify politically important actions which interpose a state directly into the conflict patterns occurring in another state, and which conceivably involve a breach of the sovereignty of the target state (albeit by invitation in some cases). The collection identifies intervener and target countries and specifies the starting and ending dates of the intervention. A series of potential interests in or motives for intervention are presented, including effects on the target's domestic disputes, foreign or domestic policies, and efforts to protect social factions in the target, to attack rebels in sanctuaries across borders ("hot pursuit"), to protect or enhance economic/resource interests, to protect military or diplomatic facilities, to save lives, or to affect regional power balances and strategic relations. Information is provided on the direction of the intervention, i.e., to support or oppose the target government, to support or oppose opposition groups in the target, or to support or oppose third-party governments or opposition groups. Other variables show the degree of prior intervention, the alliance or treaty relationship between intervener and target, prior colonial status, prior intervention, and measures of intervener and target power size. A series of intensity measures, such as battle-related casualties, is also included. For each type of incursion, by land, sea, or air, an ordinal scale of involvement is presented, ranging from minor engagement such as evacuation, to patrols, acts of intimidation, and actual firing, shelling, or bombing. Finally, contiguity information is provided to indicate both whether intervener and target are geographically contiguous, and whether the intervention was launched from contiguous territory.

This data was collected as part of an expedition to the Pacific Ocean and Atlantic Oceans to map and study the distribution of trace elements and isotopes as part of the International GEOTRACES Program (a program which aims to improve the understanding of biogeochemical cycles and large-scale distribution of trace elements and their isotopes in the marine environment). hundreds of samples were collected, processed, and analyzed along the two transects: EPZT in the Eastern Pacific between Peru and Tahiti, and GEOVIDE in the North Atlantic and Arctic between Portugal and Newfoundland, Canada. Along both transects, samples were collected at specific stations and the activity of the radionuclides was measured on both particle (small and large) and in the water column.

The City of Detroit Open Data Portal allows access to datasets, maps, charts, and files and documents on City of Detroit government operations and programs, public safety (Detroit Police Department, Detroit Fire Department, and Detroit Department of Homeland Security), property and parcels, schools and educational institutions, transportation, public health, and permits.

The National Survey on Drug Use and Health provides up-to-date information on tobacco, alcohol, and drug use, mental health and other health-related issues in the United States. NSDUH began in 1971 and is conducted every year in all 50 states and the District of Columbia. Information from NSDUH is used to support prevention and treatment programs, monitor substance use trends, estimate the need for treatment and inform public health policy.

From the MDHHS website: "The MiTracking Program gathers existing Michigan-specific environmental and health data and provides them in one online location. These data can be easily queried on the MiTracking data portal. Results are provided in tables, charts, and maps that can be downloaded, saved, and printed. The data provided by the MiTracking program can create greater awareness of environmental health concerns, and inform public health actions and programs."

An extensible, scalable informatics platform for traumatic brain injury (TBI) relevant data (including medical imaging, clinical assessment, environmental and behavioral history, etc.) and for all data types (text, numeric, image, time series, etc.). FITBIR is sponsored by the U.S. Army Medical Research and Materiel Command (USAMRMC) and supported by the National Institutes of Health National Institute of Neurological Disorders and Stroke (NINDS) and Center for Information Technology (CIT).
