Source:1 foot contours were generated for each production block from the final bare earth DEMs using ArcGIS software. Using ArcGIS software, the contours were validated for correct topology, including must not intersect, must not self intersect, and must not have dangles. Contours are then manually reviewed with the 3D breaklines to ensure complete coverage, correct coding, data integrity and that contours behave correctly around water bodies, water crossings, and elevated features such as overpasses. The contours are then clipped to individual tiles as creating one dataset for the entire project renders the feature class un-usable. Enclosed contours completely within building footprints were removed from the final contour dataset. Coordinate System:The data was developed based on a horizontal datum/projection of NAD83 (2011), State Plane Connecticut, U.S. Survey Feet and vertical datum of NAVD88 (GEOID18) Development:This vector tile package contains contour lines originally derived in the State Plane coordinate system. Prior to generating the tile service, individual contour blocks were merged into a single, seamless data layer to ensure consistency and completeness across the project area. This unified dataset served as the basis for creating the vector tile package. During the creation of the vector tile index, Web Mercator was used as the tiling reference to enable proper indexing and tile generation within ArcGIS Online. Please note that while the vector tile index references Web Mercator for mapping and display purposes, the contour line geometries are aligned with the original State Plane coordinate system, maintaining consistency with the source data used in production.

Designated Coastal Zone of San Luis Obispo County. Lands identified on the official maps of the Land Use Element as being located within the Local Coastal Plan (LCP) Combining Designation. The California Coastal Zone of San Luis Obispo County was established by the California Coastal Act of 1976. The Coordinates for this dataset are State Plane Coordinate System, Zone 5, NAD 1983 Feet.Required for planning purposes under the jurisdiction of the Local Coastal Plan - the land use polices are different between the coast and the inland areas of the County. This data provides suitable land use designation information for many mapping applications. This data is appropriate for use at a regional scale and is intended as a reference. The original 1977 Coastal Zone Boundary maps were mylar (drafting film) copies of 161 USGS 7.5 minute topographic quadrangles with an inked boundary added. This digital version of the boundary was developed to provide a georeferenced, attributed (to explain the basis of the mapped Coastal Zone), cadastral (parcel-based) depiction of the adopted Coastal Zone Boundary for the planning and regulatory activities of the Coastal Commission, local governments and others. However, it does not represent "survey" accuracy information, and may not eliminate the need for a formal boundary determination. Public Resources Code (PRC) Section 30103(a) specifically defines California's Coastal Zone as that land and water area of the State of California from the Oregon border to the border of the Republic of Mexico depicted on maps identified and set forth in Section 17 of that chapter of the Statutes of the 1975-76 Regular Session enacting PRC Division 20 (the Coastal Act of 1976). PRC Section 30103(b) directed the Coastal Commission to prepare and adopt more detailed 1:24,000 scale Coastal Zone Boundary (CZB) maps, which occurred March 1, 1977. These 161 adopted maps provide the official basis for all other representations of the landward CZB. The digital version of the CZB created by developing this shapefile is a conformed copy of the official boundary, and in some locations reflects legislative changes and Coastal Commission minor adjustments adopted from time to time since March 1977.

In December 2024, the Lower Mississippi-Gulf Water Science Center (LMGWSC) conducted comprehensive field surveys of Lake Pushmataha, a central Mississippi reservoir owned by the Mississippi Band of Choctaw Indians (MBCI) and named in honor of Chief Pushmataha. These surveys aimed to provide high-resolution spatial data to support the Bureau of Indian Affairs (BIA) in designing and implementing safety rehabilitation measures for Lake Pushmataha Dam. Bathymetric data collection took place from December 9 to 12 using a high-resolution multibeam mapping system (MBMS), which included a multibeam echosounder (MBES) and an inertial navigation system (INS) mounted on a 21-foot marine survey vessel following methodologies outlined by Huizinga (2018). To capture shallow areas inaccessible to the MBMS vessel, a single beam echosounder (SBES) and an INS were mounted on a Jon boat and used for additional mapping on December 13. Topographic data covering land elevations and positions within approximately 0.25 miles of Lake Pushmataha's shoreline were collected on December 10 and 11 using an unmanned aircraft system (UAS) equipped with a light detection and ranging (lidar) scanner. This portion of the survey was conducted by Phoenix Unmanned LLC, a specialized provider of remotely piloted aircraft with advanced remote sensing capabilities. The processed multibeam, single beam, and lidar datasets were merged and saved in compressed LASer file format (.laz) as three-dimensional (3D) point geometries in units of US survey feet, with classification codes following the American Society for Photogrammetry and Remote Sensing (ASPRS) lidar point standard (ASPRS, 2011; ASPRS, 2013). The merged dataset is provided with this data release projected in the Mississippi East State Plane coordinate system, with horizontal reference to the North American Datum of 1983 (NAD83, 2011 realization) and vertical reference to the North American Vertical Datum of 1988 (NAVD88). To facilitate evaluations of lake and dam morphology, points classified with code 2 (ground) and code 40 (bathymetric point) were extracted from the provided LAZ file to generate a Triangulated Irregular Network (TIN), which was exported in a Computer-Aided Design (CAD)-compatible format as a DXF (Drawing Exchange Format) file and included with this data release at the request of the BIA for their convenience. Additionally, a shapefile containing coverage polygons representing the approximate spatial extent of each survey method (single-beam, multibeam, or lidar) is included to aid in the interpretation and spatial context of the collected data. Summary of files included with this data release: LakePushmataha_pointcloud.laz: A dataset containing processed multibeam, single beam, and lidar data that have been merged into a single 3D point geometry dataset in compressed LASer file format, suitable for various applications in geographic information systems (GIS) and engineering. LakePushmataha_TIN.dxf: A Triangulated Irregular Network (TIN) generated in CloudCompare using the mesh creation tool, based on points classified as ground (code 2) and bathymetric point (code 40) from the topo-bathymetric dataset (LakePushmataha_PointCloud.laz). The point cloud was sub-sampled to a minimum spacing of 2 feet before meshing. Elevation values are stored in the "Z" coordinate of each TIN face vertex and are referenced to NAVD88 in feet. Horizontal vertex coordinates are referenced NAD83 (2011) and projected in feet to the Mississippi State Plane coordinate system. CUBE_uncertainty_270khz.tif: A raster file containing gridded uncertainty values at the 95% confidence interval, measured in feet, from a multibeam echo sounder (MBES) survey. Uncertainty was estimated through the Combined Uncertainty and Bathymetric Estimator (CUBE) method in HYPACK software, utilizing depth data collected at a frequency of 270 kHz, which showed the lowest bias relative to a merged bathymetric surface (see Attribute Accuracy for details). The raster has a grid size of 5 feet and is projected in the Mississippi East State Plane coordinate system. survey_extents.zip: A zipped directory containing an ESRI Shapefile of coverage polygons representing the approximate spatial extent of the respective survey method (single-beam, multibeam, or lidar). PhoenixUnmanned_lidar_processingreport.pdf: A processing report generated by Phoenix Unmanned, LLC that documents lidar performance, calibration, and accuracy tests.

For the coastal regions of Maryland, the Maryland Geological Survey (MGS) has periodically compiled maps depicting shoreline position at several points in time. The most recent compilation -- the first electronic one -- involved (1) digitizing historical (1841-1977) shoreline maps, all derived directly or indirectly from National Oceanic and Atmospheric Administration coastal survey maps (topographic or T-sheets), and (2) interpreting recent (1988-1995) shorelines from digital orthophotography. MGS is using the shorelines to update a series of Shoreline Changes maps and to determine coastal land loss, by watershed and by county, during the last half of the 20th century.

This data set contains past shorelines, dating from 1841 to 1995, for 125 7.5-minute quadrangles covering the coastal regions of Maryland (see below). Originally in MicroImage's TNTmips .rvc format, the shoreline vectors have been converted to Arc/Info "Export" (.e00) format. They are registered to the Maryland State Plane Coordinate System (North American Datum of 83, meters).

Spatial Reference Information:

-Map Projection Name: Lambert Conformal Conic
-Grid Coordinate System Name: State Plane Coordinate System 1983
-SPCS Zone Identifier: 1900 (Maryland)
-Planar Distance Units: meters
-Horizontal Datum Name: North American Datum of 1983
-Ellipsoid Name: Geodetic Reference System 80
-Semi-major Axis: 6,378,137 meters
-Denominator of Flattening Ratio: 298.257
-Depth Datum Name: The aerial photography from which the DOQQs were
 developed was not tide-coordinated. Therefore, shorelines in this data
 set does not represent a consistent vertical datum.

Shoreline Attributes:

-beach
-vegetated
-structure
-water edge

All four categories are linear features, except "beach" which, if sufficiently wide, can be both linear and polygonal. Shorelines were merged into 7.5-minute quadrangles, provided that the aerial photography on which the DOQQs were based was flown in the same year

The North Carolina Department of Administration, State Property Office in cooperation with the North Carolina Center for Geographic Information and Analysis have developed the boundary dataset for land owned by the State of NC. Examples of property included are Department of Transportation maintenance yards, state parks, state universities, historical sites, game lands managed by the Wildlife Resources Commission as well as property from additional departments assigned management responsibilities of real property. Data was prepared by digitization based on plats and legal descriptions of property.This dataset was prepared from State Property Office data for distribution through NC OneMap by the North Carolina Center for Geographic Information and Analysis. The Department of Administration (DOA), State Property Office (SPO) databases are continually updated as part of an ongoing effort to maintain an inventory of state-owned property.Digitization is completed with the NAD 1983 State Plane North Carolina FIPS 3200 coordinate system and transformed to WGS 1984 Web Mercator for web mapping. This may result in offsets from the original data due to the transformation process.

These data provide a comprehensive survey of peak-stage indicators along the Colorado River corridor between river mile (RM) 0 and RM 87 (see Figure 1 in the associated USGS-SIR). In 2008, the locations of peak-stage indicators in three short reaches downstream from RM 87 were measured using a handheld GPS unit (see Appendix 1 in the associated USGS-SIR). Total-station measurements were made using an established network of survey control that references the 2011 realization of NAD83 (NAD83 (2011)) (Kaplinski and others, 2017). The measurements were projected into the State Plane Coordinate System of 1983, Arizona central zone (FIPS zone 0202). Vertical positions are provided in both NAD83 ellipsoid heights and in NAVD88 orthometric elevations modeled from GEOID12b.
