Title: State Legislative Districts - Senate
Status: Completed
Publication Date: 2016-01-01
Abstract:

This is a derivative product that only contains districts within 12 Nautical Miles and the three closest to the U.S. coastline created specifically for the MarineCadastre.gov Ocean Reporting Tool. The 2016 cartographic boundary shapefiles are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible, generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based files while others are available only as state-based files. SLDU stands for State Legislative District Upper Chamber. State Legislative Districts (SLDs) are the areas from which members are elected to state legislatures. The SLDs embody the upper (senate) and lower (house) chambers of the state legislature. Nebraska has a unicameral legislature and the District of Columbia has a single council, both of which the Census Bureau treats as upper-chamber legislative areas for the purpose of data presentation; there are no data by SLDL for either Nebraska or the District of Columbia. A unique three-character census code, identified by state participants, is assigned to each SLD within a state. In Connecticut, Illinois, Louisiana, Maine, Maryland, Massachusetts, Michigan, Ohio, and Puerto Rico, the Redistricting Data Program (RDP) participant did not define the SLDs to cover all of the state or state equivalent area. In these areas with no SLDs defined, the code "ZZZ" has been assigned, which is treated as a single SLD for purposes of data presentation. The boundaries of the 2016 state legislative districts were provided by state-level participants through the RDP and reflect the districts used to elect members in or prior to the November 2016 election.

Purpose:

To support coastal and ocean planning and other activities pursuant to the Energy Policy Act, Coastal Zone Management Act, Magnuson-Stevens Fishery Conservation and Management Act, National Environmental Policy Act, Rivers and Harbors Act and the Submerged Lands Act. TIGER/Line files were specifically created to support small-scale thematic mapping, and to improve the appearance of shapes at small scales which were utilized in the creation of this layer.

Supplemental Information:

The native coordinate system for this layer is WGS 1984 World Mercator (ESPG: 3395). Please note: all MarineCadastre.gov data served by the NOAA Office for Coastal Management and hosted through Esri REST services are in the WGS 1984 Web Mercator Auxiliary Sphere (EPSG: 3857) projection.

Process Steps

Process Step 1

CC ID: 791155
Description:

Created a 12 NM buffer around the coast line. Selected the overlapping polygons (also the three closest polygons to the coast) and extracted them to a new feature class.

Process Date/Time: 2018-03-26 00:00:00

Process Step 2

CC ID: 791156
Description:

The American Samoa Districts were received from the American Samoa Coastal Management Program. American Samoa Counties were used to designate the administrative district of Manu'a, which is made up of the counties on the islands of Ofu, Olosega and Ta'u (the Manu'a group).The counties file originates from the American Samoa Atlas of 1981. Villages on the islands of Tutuila and Aunu'u in American Samoa were dissolved to make up the Eastern and Western Districts. The villages file originates from the American Samoa Atlas of 1981.

Process Date/Time: 2018-04-26 00:00:00

Process Step 3

CC ID: 791157
Description:

Downloaded individual state shapefiles from the US Census Bureau. Merged all shapefiles into one feature class. Projected into World Mercator

Process Date/Time: 2018-03-26 00:00:00

Process Step 4

CC ID: 791158
Description:

Added attributes for StateName, INTPTLON, INTPTLAT, NAMELSAD. The NAMELSAD attribute is a combination between NAME and the domain value associtted with the LSAD attribute. LA, MA, MD, and PR had waterway slivers coded as "State House Districts not defined" which were removed from the dataset. The StateName is based off of the StateEFP and the INTPTLON/INTPTLAT are the Longtitude and Latitude Coordinates of the polygons Centroid

Process Step 5

CC ID: 791159
Description:

U.S Territories districts of the Commonwealth of the Northern Mariana Islands, Guam, and the U.S. Virgin Islands were downloaded from the US Census Bureau TIGER/Line- Island Areas Demographic Profiles and processed as follow: Virgin Islands sub districts were dissolved into the two separate main districts of St. Croix and St. Tomas/St. John. Then merged into the coastal State Legislative Districts- House FC.
