Description: Precinct (voting district) polygon boundaries for 2022 collected by the Maryland Department of Planning (Planning) from counties (including Baltimore City) or digitized by Planning in coordination with counties, with precinct numbers reformatted as necessary for statewide consistency (see VTD field specifications below). All data are reprojected to WGS 1984 Web Mercator (auxiliary sphere) consistent with iMap standards, but precincts are otherwise delineated as received from counties. Planning may complete minor future adjustments to ensure precincts are edge matched with Census block boundaries. Precincts are not included for counties that have not yet submitted countywide precinct data. This feature class will be updated as additional or revised precinct datasets are received. Fields include: JURSCODE (Jurisdiction Code) – MdProperty View jurisdiction code (four-letter county or Baltimore City code)
