TwitterThis service provides vector polygon dataset defining the official boundaries of the 100 counties within North Carolina as well as the boundaries between North Carolina and the states which border North Carolina.The North Carolina county polygon boundary service provides location information for North Carolina State and County Boundary lines derived from the best available survey and/or Geographic Information System (GIS) data. Sources for information are the North Carolina Geodetic Survey (NCGS), NC Department of Transportation (NCDOT), United States Geological Survey (USGS), and field surveys conducted by licensed surveyors in North Carolina and neighboring states that have been approved and recorded in their respective counties. Some boundaries cannot be surveyed in cases where boundaries are coincident with river centers. North Carolina Geodetic Survey assists counties on a cooperative basis (NC General Statute 153A-18) in defining and monumenting the location of uncertain or disputed boundaries as established by law. Some counties have completed boundary surveys for at least a portion of their county boundary. However, the majority of county boundaries have not been surveyed and are represented by the best currently available data from GIS sources, including NCDOT county maps (which originally came from the USGS) and updated county parcel maps.This data is updated annually, first quarter (usually in February).MetadataThe metadata for the contained layer of the NCDOT County Boundaries Service is available through the following link:County Boundaries PolygonPoint of Contact North Carolina Department of Information Technology -Transportation, GIS UnitGIS Data and Services ConsultantContact information:gishelp@ncdot.govCentury Center – Building B1020 Birch Ridge DriveRaleigh, NC 27610Hours of service: 9:00am - 5:00pm Monday – FridayContact instructions: Please send an email with any issues, questions, or comments regarding the County Boundaries data.

Northeastern United States County Boundary data are intended for geographic display of state and county boundaries at statewide and regional levels. Use it to map and label counties on a map. These data are derived from Northeastern United States Political Boundary Master layer. This information should be displayed and analyzed at scales appropriate for 1:24,000-scale data. The State of Connecticut, Department of Environmental Protection (CTDEP) assembled this regional data layer using data from other states in order to create a single, seamless representation of political boundaries within the vicinity of Connecticut that could be easily incorporated into mapping applications as background information. More accurate and up-to-date information may be available from individual State government Geographic Information System (GIS) offices. Not intended for maps printed at map scales greater or more detailed than 1:24,000 scale (1 inch = 2,000 feet.)

TwitterMap Index Sheets from Block and Lot Grid of Property Assessment and based on aerial photography, showing 1983 datum with solid line and NAD 27 with 5 second grid tics and italicized grid coordinate markers and outlines of map sheet boundaries. Each grid square is 3500 x 4500 feet. Each Index Sheet contains 16 lot/block sheets, labeled from left to right, top to bottom (4 across, 4 down): A, B, C, D, E, F, G, H, J, K, L, M, N, P, R, S. The first (4) numeric characters in a parcelID indicate the Index sheet in which the parcel can be found, the alpha character identifies the block in which most (or all) of the property lies.

TwitterThe Montgomery County Map Book consists of multiple maps organized into a user-friendly format. Key components of the map book include:Map Index: Divides the county into equal-sized key map grids, each assigned a unique identifier. Each key map grid contains a subgrid further divided into 24 square grids, lettered for easy reference.Transportation Lines: Each map includes transportation lines such as roads (sourced from the Montgomery County Emergency Communications District - MCECD), railroads (from the Texas Department of Transportation - TxDOT), waterlines (from the United States Geological Survey - USGS), and national forest boundaries (from the Forest Service of the United States Department of Agriculture - USDA).Municipal Boundaries: Displays municipal boundaries sourced from the Montgomery Central Appraisal District (MCAD), providing context for local governance and jurisdictional boundaries.Common Places: Includes various points of interest and common places within Montgomery County, ranging from public/government facilities (e.g., post offices, law enforcement, fire departments, schools) to private/commercial locations (e.g., assisted living facilities, banks, golf courses, parks).Each key map within the map book is letter-sized (8.5x11 inches) and shares a consistent map scale of 1 inch equals 2,800 feet. The map book is designed to facilitate navigation and spatial analysis, with clear indications of key map numbers and adjacent key maps for reference.Data Sources:Transportation Lines: Montgomery County Emergency Communications District (MCECD), Texas Department of Transportation (TxDOT), United States Geological Survey (USGS)Municipal Boundaries: Montgomery Central Appraisal District (MCAD)Common Places: Montgomery County GIS DepartmentAccess Requirements: Access to the Montgomery County Map Book is open to the public and stakeholders interested in county geography and spatial information.

TwitterPolygon vector map data covering county boundaries for DeKalb County, Georgia containing 1 feature.
Boundary GIS (Geographic Information System) data is spatial information that delineates the geographic boundaries of specific geographic features. This data typically includes polygons representing the outlines of these features, along with attributes such as names, codes, and other relevant information.
Boundary GIS data is used for a variety of purposes across multiple industries, including urban planning, environmental management, public health, transportation, and business analysis.
Available for viewing and sharing as a map in a Koordinates map viewer. This data is also available for export to DWG for CAD, PDF, KML, CSV, and GIS data formats, including Shapefile, MapInfo, and Geodatabase.
