About the data

Parcels
This layer represents the parcel boundaries for Lawrence County. It is copied once a day from the working county GIS. Typically the working county GIS reflects ownership transfers, platting and breakouts 6 to 8 weeks after the filing date with the Register of Deeds Office.
Note: From November 1 to April 1 plats, transfers and breakouts filed with the Register of Deeds Office are not processed in the Equalization Office and will not be reflected on this GIS until 6 to 8 weeks after April 1.

Structures
This layer represents structures and address points in Lawrence County. The points are created with GPS for structures and address points outside city limits and are updated daily.

3 Mile Area
This layer represents the area around the Spearfish city limits designated as the Joint Powers and the Extraterritorial Jurisdiction (ETJ). Within these areas the city of Spearfish has jurisdiction over certain functions as noted below.
ETJ - Platting.
JP - Building Permits, Flood Plain Administration, and Variances.
ETJ & JP - Building Permits, Flood Plain Administration, Variances, and Platting.
Cities
This layer represents the current Lawrence County municipality boundaries and is updated daily.

Voting Districts
This layer represents the current voting precincts of Lawrence County. It is updated daily.

Flood_100Year
This layer is the FEMA Q3 Flood Data. It is a digital representation of certain features of FEMA's Flood Insurance Rate Maps (FIRM). Digital Q3 Flood Data has been developed by scanning the existing FIRM hardcopy and does not reflect any changes from the original publication date. This layer delineates Special Flood Hazard Areas (SFHA)-land areas subject to inundation by a flood that has a 1-percent probability of being equaled or exceeded in any given year. For up-to-date information on flood hazard areas, contact the Lawrence County Planning and Zoning Office or your city flood administrator if you are within city limits or the 3-Mile area around Spearfish (see map).

County Zoning
This layer represents the current Lawrence County Zoning outside city limits. It is updated daily.

As_100ppm
This layer represents the Whitewood superfund boundary. It is provided by Homestake Mining Company.

Roads and Highways
This layer represents the Lawrence County 911 roads data. It is created using GPS and only shows roads that service a 911 address. It is updated daily.

Contours
This layer represents the Lawrence County elevation contours.

Recreation and Snow mobile trails
These layers show recreation trails and snow mobile trails

Topo
This raster layer is a digital representation of the Forest Service quad maps.

County Aerial
This data set contains imagery from the National Agriculture Imagery Program (NAIP). NAIP acquires digital ortho imagery during the agricultural growing seasons in the continental U.S.. A primary goal of the NAIP program is to enable availability of ortho imagery within one year of acquisition. NAIP provides two main products: 1 meter ground sample distance (GSD) ortho imagery rectified to a horizontal accuracy of within +/- 5 meters of reference digital ortho quarter quads (DOQQ's) from the National Digital Ortho Program (NDOP) or from the National Agriculture Imagery Program (NAIP); 1 meter GSD ortho imagery rectified to within +/- 6 meters to true ground. The tiling format of NAIP imagery is based on a 3.75' x 3.75' quarter quadrangle with a 300 meter buffer on all four sides. NAIP quarter quads are formatted to the UTM coordinate system using NAD83. NAIP imagery may contain as much as 10% cloud cover per tile. This file was generated by compressing NAIP quarter quadrangle tiles that cover a county. Two types of compression may be used for 2008 NAIP imagery: MrSID and JPEG 2000. Target values for the compression ratio are (15:1).
