X-ray images in this data set have been acquired from the tuberculosis control program of the Department of Health andHuman Services of Montgomery County, MD, USA. This set contains 138 posterior-anterior x-rays, of which 80 x-rays are normal and 58 x-rays areabnormal with manifestations of tuberculosis. All images are de-identified and available in DICOM format. The set covers a wide range of abnormalities,including effusions and miliary patterns. The data set includes radiology readings available as a text files and summary of its content

Lung Segmentation Data Kit is a collection of 385 Chest X-Rays (CXRs) and corresponding lung masks included in both Japanese Society of Radiological Technology (JSRT) and Montgomery dataset. The CXRs included in Montgomery set, as well as their masks, are augmented and resized to the standard JSRT resolution of 2048x2048 pixels. The intensity values of CXR images included in JSRT set are normalised to the intensity values of images included in Montgomery set.

The dataset was created in order to train and test Machine Learning based Lung Segmentation Methods on a single unified and denoted dataset instead of two separate ones. The Data Kit provides the end user with more diverse but unified dataset that resembles to the real-life situations.

As part of our ongoing commitment to promote transparency, accountability, innovation and citizen engagement, Montgomery County has designed this data site to provide information on county initiatives and as a place to access the County's official published GIS data and applications.

This resource is a member of a series. The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The All Roads Shapefile includes all features within the MTDB Super Class "Road/Path Features" distinguished where the MAF/TIGER Feature Classification Code (MTFCC) for the feature in MTDB that begins with "S". This includes all primary, secondary, local neighborhood, and rural roads, city streets, vehicular trails (4wd), ramps, service drives, alleys, parking lot roads, private roads for service vehicles (logging, oil fields, ranches, etc.), bike paths or trails, bridle/horse paths, walkways/pedestrian trails, and stairways.

Margin of Error

Data in the dataset are based on the estimates and are subject to sampling variability and thus a margin of error. Neilsberg Research recommends using caution when presening these estimates in your research.

Montgomery and Prince George's counties project called for the Planning, Acquisition, processing and derivative products of lidar data to be collected at a nominal pulse spacing (NPS) of 0.7 meter. Project specifications are based on the U.S. Geological Survey National Geospatial Program Base Lidar Specification, Version 1.2. The data was developed based on a horizontal projection/datum of NAD83 (HARN), State Plane, Feet and vertical datum of NAVD88 (GEOID12B), Feet. Lidar data was delivered as processed Classified LAS 1.4 files, formatted to 1,413 individual 4000 ft x 6000 ft tiles, as tiled Intensity Rasters, and as tiled bare-earth DEM; all tiled to the same 4000 ft x 6000 ft schema. Ground Conditions: Lidar was collected in early to mid 2018, while no snow was on the ground and rivers were at or below normal levels. Sensor errors in mulitple locations were identified in processing, additonal acquisition on 7/20/2018 was completed to remedy the errors. 2016 lidar data was used with approval in a single area of restricted airspace. In order to post process the lidar data to meet task order specifications and meet ASPRS vertical accuracy guidelines, Sanborn Map Company, Inc. established a total of 23 ground control points that were used to calibrate the lidar to known ground locations established throughout the project area. An additional 79 independent accuracy check points in Open Terrain and Urban landcovers were used to assess the vertical accuracy of the data. These check points were not used to calibrate or post process the data.This is a MD iMAP hosted service.

Montgomery County, MD - Unemployment Rate: 35 years of historical data from 1990 to 2025.

Montgomery County DHCA classifies properties as Troubled, At-Risk, and Compliant through scheduled property code inspections. In general, a “Troubled Property” is a multifamily rental property with numerous and or severe “health and safety” housing code violations. The full Fiscal Year 2024 Troubled Property report for properties inspected between July 1, 2023 and June 30, 2024, is available at https://www.montgomerycountymd.gov/dhca/director/TroubledProperties.html. This report provides the results and classifications of the properties inspected and identifies the properties to be inspected in the following Fiscal Year. FY24 Data will be uploaded to Data Montgomery in the coming weeks. Executive Regulation 05-17 provides a methodology for designating certain multifamily rental housing units as "Troubled Properties" These "Troubled Properties" are subject to at least annual housing code inspections and must develop and implement a corrective action plan. This dataset provides housing code inspection results along with scores for both severity and quantity of violations.
