The PWC GIS Data Portal is the platform used to increase public access to valuable GIS data created, maintained, licensed, and stored by Prince William County for county agencies and the people we serve.Browse by category or enter keywords in the search box to locate a dataset of interest, read its description, learn more about its authoritative data source, and explore attributes before downloading.

This layer is for the recreational parks in Prince William County of all levels. The layer includes federal, state, county, and private parks. It is intended for use on County Mapper and other mapping applications but is also used to track park land in PWC

Vector polygon map data of property parcels from Prince William County, Virginia containing 152,739 features.

Property parcel GIS map data consists of detailed information about individual land parcels, including their boundaries, ownership details, and geographic coordinates.

Property parcel data can be used to analyze and visualize land-related information for purposes such as real estate assessment, urban planning, or environmental management.

Available for viewing and sharing as a map in a Koordinates map viewer. This data is also available for export to DWG for CAD, PDF, KML, CSV, and GIS data formats, including Shapefile, MapInfo, and Geodatabase.

The Arctic Strategic Transportation and Resources (ASTAR) project worked with North Slope communities and regional stakeholders to identify infrastructure development projects that offered the most benefit to stakeholders by prioritizing community and cultural connectivity, regional support, reduced cost of living and increased safety. The project was a collaborative effort initiated by the Alaska Department of Natural Resources in partnership with the North Slope Borough. The planning area includes the entire North Slope region, including State lands, the National Petroleum Reserve-Alaska (NPR-A) and the Arctic National Wildlife Refuge (ANWR). A document providing an overview of the project and methodology can be downloaded using the ASTAR Methodology button below. Prior to analysis, a review of prioritization tools and decision processes was conducted. This review is also available for download below using the Project Prioritization Tools button. TRAINING VIDEO: This video demonstrates how to use the ASTAR Project Prioritization Tool. This tool is described in ASTAR documentation as Cumulative Benefits Analysis; however, it was renamed the Project Prioritization Tool to more accurately reflect its use. The tool was created from an open source tool called SplendidCRM that was modified to meet the needs of these analyses. There are four primary modules: Accounts, Projects, Surveys, and Analysis. The tool combines pairwise comparison (PWC), analytical hierarchy (AHP), and weighted decision making (WDM) processes to rank infrastructure projects according to their benefit to regional stakeholders based on stakeholder input. The ASTAR team conducted project scoping and data collection efforts in support of this project. Reports documenting Stakeholder Engagement, Transportation Study, Socioeconomic References and Workforce Development Plan are provided through the PLANNING link below. The ASTAR data inventory and data management plan are also available through the ASTAR PLANNING link. The ASTAR team developed specialized geographic cost surface (CS) tools for this project to facilitate consideration of site/route selection scenarios. Documentation and access to these tools are provided through the ASTAR CS TOOL link below. Based on project prioritization analysis, the ASTAR team selected three infrastructure projects for evaluation: Atqusuk-Utquagvik routing, Utqiagvik-Atqasuk-Wainwright routing and Colville River crossing. The data used and results for these studies are provided through the ASTAR STUDIES link below. Raster GIS data sets were created for the North Slope region with common origin points that are intended for use with CS tools. They represent elevation (2m DEM ~400GB), slope (~400GB) and hydrodensity (~20 GB). In addition a permanent road, cost surface raster data set (~6 GB) was generated for the North Slope. These products are available for use; however, due to their large size, distribution of these products will only be available by direct request. Please contact NSSI Data Management for further information. Note: DEM data for the region are available for download online through USGS and DGGS. Further description of the ASTAR project is available at the ASTAR DNR project website that is available through the link below.

These data represent marine waters used for motorized boating, which includes transit, mooring or anchoring by motorized vessels for commercial or recreational purposes, and personal watercraft (PWC). Excludes fishing, wildlife viewing at sea, cruise ships, shipping, and sailing.

Motorized boating is not a common activity for purely recreational purposes (mainly related to wildlife viewing, fishing or other commercial pursuits). The use mainly occurs along the Strait and within bays and harbors for transit purposes.

Tribal uses of the ocean were not mapped explicitly, though tribal chairs and/or their designated representatives were formally invited by BOEM to participate in the mapping workshops. The sharing of tribal use information was dependent upon each tribe’s determination of whether the mapping workshops were an appropriate forum for sharing such information. Any tribal use information shared during the workshops was incorporated into the defined use categories. Thus, the atlas data and map products do not explicitly depict tribal use.
