Geographic Extent: SANDY_Restoration_DE_MD_QL2 Area of Interest covers approximately 3.096 square miles. Lot #5 contains the full project area Dataset Description: The SANDY_Restoration_DE_MD_QL2 project called for the Planning, Acquisition, processing and derivative products of LiDAR data to be collected at a nominal pulse spacing (NPS) of 0.7 meters. Project specifications are based on the U.S. Geological Survey National Geospatial Program Base LiDAR Specification, Version 1. The data was developed based on a horizontal projection/datum of State Plane Zone Maryland (1900), NAD83, feet and vertical datum of NAVD1988 (GEOID12A), feet. LiDAR data was delivered in RAW flight line swath format, processed to create Classified LAS 1.2 Files formatted to 3842 individual 1500m x 1500m tiles, and corresponding Intensity Images and Bare Earth DEMs tiled to the same 1500m x 1500m schema, and Breaklines in ESRI shapefile format. Ground Conditions: LiDAR was collected in Winter 2013 / Spring 2014, while no snow was on the ground and rivers were at or below normal levels. In order to post process the LiDAR data to meet task order specifications, Quantum Spatial established a total of 78 QA control points and 99 Land Cover control points that were used to calibrate the LiDAR to known ground locations established throughout the SANDY_Restoration_DE_MD_QL2 project area.This is a MD iMAP hosted service.

Geospatial data about Dorchester County, South Carolina Parcels. Export to CAD, GIS, PDF, CSV and access via API.

This data was developed in response to citizens’ road maintenance requests from across the state as to whom to contact as the official maintenance authority - be it MDOT State Highway Administration, MDOT Transportation Authority, a county, or a municipality.MDOT SHA Website

Navigation Aids dataset current as of 2008. Dorchester County Channel Markers - Planimetric Data.

Fire Boxes within the Salisbury Fire Response Zone. Developed based on the output of a response time analysis. This analysis was used to determine the response order first through fifth due to all 911 addresses in the response zone. Boxes were created based on areas of identical first through fifth response due. Then, Geographic locations of Fire Stations in Wicomico County, Somerset County, Dorchester County, Worcester County, and Southern Delaware that have mutual aid agreements with Wicomico County and the City of Salisbury Fire Chiefs were used to aid the City of Salisbury and Wicomico County Emergency Services with developing a run order for 6st through 20th as a direct path from the station to the fire box. The results of the analysis were delivered to Wicomico County Emergency Services to be ingested into the County Fire CAD system.

The paleochannel is an ancient buried underground riverbed with approximately seven billion (7,000,000,000) gallons of water, which extends into the northerly portion of Wicomico County from Dorchester County and which has been nominated by the city council and designated as an area of critical state concern by the Maryland Department of State Planning. The paleochannel extends into Salisbury along its northerly corporate limits, has been mapped and studied in its known portion by the Maryland Geological Survey, provides potable water for the city of Salisbury and is a potentially unlimited source of water for both Salisbury and Wicomico County. Because of its vast potential as a potable abundant water supply, protective measures, in the form of use limitations and review procedures, are necessary to ensure that it is protected from contamination while continual study is done of the paleochannel's recharge areas and its capabilities and limitations. The following district, uses and development standards have been developed based upon this purpose, which is in accord with the findings and recommendations for the paleochannel in the city's adopted metro core comprehensive plan.In addition to two wells located in the paleochannel (known as the "paleo wells"), the city of Salisbury has nine wells located along the banks of the South Prong of the Wicomico River (Beaverdam Creek) from which potable water is obtained. These wells are known as the "park wells."

Aerial Cartographics of America, Inc. collected LiDAR for over 681 square miles in Accomack, Dorchester, Somerset, Sussex, Wicomico, and Worchester Counties in Maryland, Delaware and Virginia. The nominal pulse spacing for this project was no greater than 0.7 meters. This project was collected with a Riegl LMS-Q680i Full Waveform LiDAR Sensor which collects an intensity value, GPS Week Time, Flightline and echo number attributes for each discrete pulse. Dewberry used proprietary procedures to classify the LAS into an initial ground surface. Dewberry used proprietary procedures to classify the LAS and then performed manual classifications according to project specifications: 1-Unclassified, 2-Ground, 7-Noise, 9-Water, and 10-Ignored Ground due to breakline proximity. Dewberry produced 3D breaklines and combined these with the final LiDAR data to produce seamless DTMs, DSMs and hydro flattened DEMs, for 833 tiles (1500 meters x 1500 meters) that cover the project area.This is a MD iMAP hosted service.
