This is a MD iMAP hosted service layer. Find more information at http://imap.maryland.gov. The purpose of the 2010 land use/land cover data set is to provide a generalized view of how developed land has changed throughout the state - primarily capturing the conversion of resource land to development and characterizing the type of development (e.g. very low density - low density - medium density or high density residential development - commercial - industrial - institutional). Urban Land Uses: 11 Low-density residential - Detached single-family/duplex dwelling units - yards and associated areas. Areas of more than 90 percent single-family/duplex dwelling units - with lot sizes of less than five acres but at least one-half acre (.2 dwelling units/acre to 2 dwelling units/acre). 12 Medium-density residential - Detached single-family/duplex - attached single-unit row housing - yards - and associated areas. Areas of more than 90 percent single-family/duplex units and attached single-unit row housing - with lot sizes of less than one-half acre but at least one-eighth acre (2 dwelling units/acre to 8 dwelling units/acre). 13 High-density residential - Attached single-unit row housing - garden apartments - high-rise apartments/condominiums - mobile home and trailer parks; areas of more than 90 percent high-density residential units - with more than 8 dwelling units per acre. 14 Commercial - Retail and wholesale services. Areas used primarily for the sale of products and services - including associated yards and parking areas. 15 Industrial - Manufacturing and industrial parks - including associated warehouses - storage yards - research laboratories - and parking areas. 16 Institutional - Elementary and secondary schools - middle schools - junior and senior high schools - public and private colleges and universities - military installations (built-up areas only - including buildings and storage - training - and similar areas) - churches - medical and health facilities - correctional facilities - and government offices and facilities that are clearly separable from the surrounding land cover. 17 Extractive - Surface mining operations - including sand and gravel pits - quarries - coal surface mines - and deep coal mines. Status of activity (active vs. abandoned) is not distinguished. 18 Open urban land - Urban areas whose use does not require structures - or urban areas where non-conforming uses characterized by open land have become isolated. Included are golf courses - parks - recreation areas (except areas associated with schools or other institutions) - cemeteries - and entrapped agricultural and undeveloped land within urban areas. 191 Large lot subdivision (agriculture) - Residential subdivisions with lot sizes of less than 20 acres but at least 5 acres - with a dominant land cover of open fields or pasture. 192 Large lot subdivision (forest) - Residential subdivisions with lot sizes of less than 20 acres but at least 5 acres - with a dominant land cover of deciduous - evergreen or mixed forest. Agriculture: 21 Cropland - Field crops and forage crops. 22 Pasture - Land used for pasture - both permanent and rotated; grass. 23 Orchards/vineyards/horticulture - Areas of intensively managed commercial bush and tree crops - including areas used for fruit production - vineyards - sod and seed farms - nurseries - and green houses. 24 Feeding operations - Cattle feed lots - holding lots for animals - hog feeding lots - poultry houses - and commercial fishing areas (including oyster beds). 241 Feeding operations - Cattle feed lots - holding lots for animals - hog feeding lots - poultry houses. 242 Agricultural building breeding and training facilities - storage facilities - built-up areas associated with a farmstead - small farm ponds - commercial fishing areas. 25 Row and garden crops - Intensively managed truck and vegetable farms and associated areas. Forest: 41 Deciduous fore
