MD/PA Sandy Supplemental Lidar Data Acquisition and Processing Production Task USGS Contract No. G10PC00057 Task Order No. G14PD00397 Woolpert Order No. 74333 CONTRACTOR: Woolpert, Inc. This task is for a high resolution data set of lidar covering approximately 1,845 square miles. The lidar data was acquired and processed under the requirements identified in this task order. Lidar data is a remotely sensed high resolution elevation data collected by an airborne platform. The lidar sensor uses a combination of laser range finding, GPS positioning, and inertial measurement technologies. The lidar systems collect data point clouds that are used to produce highly detailed Digital Elevation Models (DEMs) of the earth's terrain, man-made structures, and vegetation. The task required the LiDAR data to be collected at a nominal pulse spacing (NPS) of 0.7 meters. The final products include classified LAS, one (1) meter pixel raster DEMs of the bare-earth surface in ERDAS IMG Format, and 8-bit intensity images. Each LAS file contains lidar point information, which has been calibrated, controlled, and classified. Additional deliverables include hydrologic breakline data, control data, tile index, lidar processing and survey reports in PDF format, FGDC metadata files for each data deliverable in .xml format, and LAS swath data. Ground conditions: Water at normal levels; no unusual inundation; no snow; leaf off. Coastal tiles 18SVH065720 and 8SVH095690 contain no lidar points as they exist completely in water. A DEM IMG was generated for these two tiles as the digitized hydro breakline assumed the data extent in the area. As such only 2568 LAS and Intensity files will be delivered along with 2570 DEM IMG's.This is a MD iMAP hosted service.

This Regional Water Table Surface Contours Upper Glacial Drift Lower Peninsula is a generalized water table surface created by using the existing Wellogic water well database as of March 2021 and using just wells screened in the upper portion of the glacial drift. The elevation of the reported static water level (SWL field) reported on the well logs was calculated by subtracting it from the elevation at each well which was based on a 10-meter DEM. The data also incorporated the elevations of the Great Lakes Shorelines and the elevation of hydraulically appropriate surface water bodies (NHD Plus) that appear to be connected to the regional aquifer system and not perched above the regional water table surface. Contours were derived at a 10 feet contour interval. The original data was mapped for the entire lower peninsula. This Kent County data was clipped out of the peninsula data.The fields found in this dataset are:Field NameDescriptionIdUnique integer in long integer formatContourGroundwater elevation value (feet above mean sea level) in double precision formatContour1Groundwater elevation value (feet above mean sea level) in long integer formatINDEXValues in long integer format that allow different index contours to be flagged, labeled, queried, and/or symbolized.INDEX10Values in long integer format that allow different index contours to be flagged, labeled, queried, and/or symbolized.INDEX5Values in long integer format that allow different index contours to be flagged, labeled, queried, and/or symbolized.Shape_LengthLength of line in feet in double precision formatThis data is used in the North Kent Study Area Data Summary Web App (Item Details).

As part of the 5-year study on the natural resources present in the Lower Chickahominy watershed (LCW), PlanRVA produced this story map to display existing eco-tourism infrastructure in the watershed and report the findings. The LCW consists of three localities: James City County, New Kent County, and Charles City County. Each county boasts some of the most unique and valuable natural resources in the state of Virginia.The study area consists of healthy streams, forested lands, and open spaces that are home to the native flora and fauna of the tidal fresh zone of coastal Virginia. Given these distinctive attributes and the county's prime location in the region, the rural area is experiencing suburban development pressure in Virginia's coastal plain. The effort of this study, funded by the Virginia Coastal Zone Management Program (CZM), aims to identify and establish an overarching vision for land use, land conservation, and sustainable economic priorities. Furthermore, the study promotes the development of various strategic approaches to harnessing both the ecological and economic value in the watershed.

The 5km Hex GS Soluble Rocks dataset shows a generalised view of the GeoSure Soluble Rocks v8 dataset to a hexagonal grid resolution of 64.95km coverage area (side length of 5km). This dataset indicates areas of potential ground movement in a helpful and user-friendly format. The rating is based on a highest level of susceptibility identified within that Hex area: Low (1), Moderate (2), Significant (3). Areas of localised significant rating are also indicated. The summarising process via spatial statistics at this scale may lead to under or over estimation of the extent of a hazard.

The supporting GeoSure reports can help inform planning decisions and indicate causes of subsidence. The Soluble Rocks methodology is based on the BGS Digital Map (DiGMapGB-50) and expert knowledge of the behaviour of the formations so defined. This dataset provides an assessment of the potential for dissolution within a geological deposit. Ground dissolution occurs when certain types of rock contain layers of material that may dissolve if they get wet. This can cause underground cavities to develop. These cavities reduce support to the ground above and can lead to a collapse of overlying rocks. Dissolution of soluble rocks produces landforms and features collectively known as 'karst'. Britain has four main types of soluble or 'karstic' rocks; limestone, chalk, gypsum and salt, each with a different character and associated potential hazards. Engineering problems associated with these karstic rocks include subsidence, sinkhole formation, uneven rock-head and reduced rock-mass strength. Sinkhole formation and subsidence has the potential to cause damage to buildings and infrastructure. Complete Great Britain national coverage is available.
