Small format grocery stores that are typically independently owned and operated. They typically have annual food sales of less than $2 million, and have limited to no food departments. Corner stores are often located on street corners and thus small, limited to one row house unit, with an emphasis on snacks over groceries, similar to convenience stores. Small groceries are often larger, two or more row house units, and emphasize groceries over snacks.

This dataset provides a digital geospatial representation of regulated facility outfalls using data derived from various source data. The process by which this data set has been developed has been guided by Maryland Department of the Environment (MDE) and is the result of multiple geoprocesses. It is important to note that point locations are approximate and many do not represent exact geographic locations of outfalls, rather the parcel that they are located in. It is also important to note that in some cases, due to the way the data was processed, outfalls and facilities may have the same coordinates, leading to points being stacked.

The purpose of this layer is to show where certain areas of cities are hotter than the average temperature for that same city as a whole. Severity is measured on a scale of 1 to 5, with 1 being a relatively mild heat area (slightly above the mean for the city), and 5 being a severe heat area (significantly above the mean for the city). The absolute heat above mean values are classified into these 5 classes using the Jenks Natural Breaks classification method, which seeks to reduce the variance within classes and maximize the variance between classes.

Superfund sites are polluted locations in the United States requiring a long-term response to clean up hazardous material contaminations. They were designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980. CERCLA authorized the United States Environmental Protection Agency (EPA) to create a list of such locations, which are placed on the National Priorities List (NPL).

The Food Access Research Atlas defines this measure as being a low-income census tract with at least 500 people or 33 percent of the population living more than ½ mile (urban areas) or more than 10 miles (rural areas) from the nearest supermarket. A low-income census tract is defined as a having either a poverty rate of 42 percent or more, or a median family income less than 80 percent of the State-wide median family income; or a tract in a metropolitan area with a median family income less than 80 percent of the surrounding metropolitan area medium family income. A census tract is urban if its geographic centroid is in an area with more than 2,500 people. All other tracts are rural.

The primary purpose of census tracts is to provide a stable set of geographic units for the presentation of census data and comparison back to previous decennial censuses. Census tracts generally have a population size between 1,200 and 8,000 people, with an optimum size of 4,000 people.
