Prof. Robert Hartwell (1932 - 1996) created his China Historical GIS under the auspices of his company Chinese Historical Studies. His estate left the data to Harvard University. These materials include functional GIS datasets for the Chinese Dynasties, from Tang to Ming, which were based on the concept of "co-location," or the use of GIS representations of modern county-level administrative units as building blocks to depict the approximate shapes of historical areas. Making use of county boundary data for 1992, (obtained from Crissman's ACASIAN data), Hartwell represented historical units that occupied roughly the same areas by merging or splitting the 1992 counties. Where the contemporary boundaries could not be "co-located" in this fashion, Hartwell drew in approximate line boundaries to divide the contemporary units to fit the historical situations and therefore provide an approximation of the historical unit's area. Although the resulting boundaries are, in many cases, problematic representations, the GIS remains an interesting hueristic GIS tool for sorting, querying, and creating digital maps for selected areas within the major dynasties up to the Ming. Harvard University released the original Hartwell datasets on April 2nd, 2001, in conjunction with the CHGIS project, as a useful means of generating approximate spatial entities correlating to historical administrative units. For Version 5, the Hartwell Datasets were renamed according to a filenaming convention (described above) and projected to match the CHGIS V5 standard (2014).

(See USGS Digital Data Series DDS-69-E) A geographic information system focusing on the Cretaceous Travis Peak and Hosston Formations was developed for the U.S. Geological Survey's (USGS) 2002 assessment of undiscovered, technically recoverable oil and natural gas resources of the Gulf Coast Region. The USGS Energy Resources Science Center has developed map and metadata services to deliver the 2002 assessment results GIS data and services online. The Gulf Coast assessment is based on geologic elements of a total petroleum system (TPS) as described in Dyman and Condon (2005). The estimates of undiscovered oil and gas resources are within assessment units (AUs). The hydrocarbon assessment units include the assessment results as attributes within the AU polygon feature class (in geodatabase and shapefile format). Quarter-mile cells of the land surface that include single or multiple wells were created by the USGS to illustrate the degree of exploration and the type and distribution of production for each assessment unit. Other data that are available in the map documents and services include the TPS and USGS province boundaries. To easily distribute the Gulf Coast maps and GIS data, a web mapping application has been developed by the USGS, and customized ArcMap (by ESRI) projects are available for download at the Energy Resources Science Center Gulf Coast website. ArcGIS Publisher (by ESRI) was used to create a published map file (pmf) from each ArcMap document (.mxd). The basemap services being used in the GC map applications are from ArcGIS Online Services (by ESRI), and include the following layers: -- Satellite imagery -- Shaded relief -- Transportation -- States -- Counties -- Cities -- National Forests With the ESRI_StreetMap_World_2D service, detailed data, such as railroads and airports, appear as the user zooms in at larger scales. This map service shows the structural configuration of the top of the Travis Peak or Hosston Formations in feet below sea level. The map was produced by calculating the difference between a datum at the land surface (either the Kelly bushing elevation or the ground surface elevation) and the reported depth of the Travis Peak or Hosston. This map service also shows the thickness of the interval from the top of the Travis Peak or Hosston Formations to the top of the Cotton Valley Group.

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. We followed methods in Anderson and Merrill (1998) for combining gradient layers into an “ecological land units” map (also referred to as a “biophysical units” map). Our goal was to use this information to create sampling strata that capture the range of environments observed. The Anderson and Merrill (1998) method (implemented as a set of GIS scripts by F. Biasi (2001)) builds an ecological units map by classifying and combining individual environmental gradient maps in a GIS. Maps of aspect, moisture, slope, and slope shape are reclassified and assembled to produce maps of landform units. These landform units are then combined with reclassified elevation and geologic maps to produce a final ecological land units or “ELU” map. We used these methods as a guide to building an ecological land units map for Shenandoah National Park, adapting the procedures for local conditions. Individual steps in the process and maps resulting from intermediate and final stages are described in the report.

Download .zipA soil mapping unit designates a specific type of soil which has unique characteristics including texture, slope, and erosion class.

These soils were digitized from the paper final soil survey sheets. These sheets were taped together to form an area covering each of the USGS 7.5 minute quadrangle maps in the county. The areas for each quadrangle were then digitized using run-length encoding technique sampling along horizontal lines which represented the midline of cells with a height of 250 feet. The measurement increment along these lines was one decafoot (10 feet). The quadrangle files were then merged into a county file which has subsequently been converted to Arc/Info format.

The user should bear in mind that this coverage is only an approximation of the soil survey and should not be used for site specific analysis.

Additional details of the digitizing process are available upon request.

Original coverage data was converted from the .e00 file to a more standard ESRI shapefile(s) in November 2014.Contact Information:GIS Support, ODNR GIS ServicesOhio Department of Natural ResourcesReal Estate & Land ManagementReal Estate and Lands Management2045 Morse Rd, Bldg I-2Columbus, OH, 43229Telephone: 614-265-6462Email: gis.support@dnr.ohio.gov Data Update Frequency: As Needed

The Groundwater Classification Areas GAA layer represents designated groundwater protection zones within the State of New Hampshire, established in accordance with RSA 485-C:5 of the Groundwater Protection Act. This act mandates the classification of all groundwater for the purpose of implementing protective measures and management practices that prevent contamination and preserve groundwater as a resource.Specifically, GAA classifications are applied to areas that receive enhanced protection due to their importance as drinking water sources or their vulnerability to contamination. These areas are typically managed by local entities or public water suppliers through an approved local groundwater management program. Reclassification to GAA status requires demonstrated commitment to pollution prevention, including land-use controls and emergency response planning, to reduce risks associated with hazardous materials such as petroleum products or industrial chemicals.The spatial features in this dataset represent the official perimeters of GAA-designated areas, and include both state-mandated and locally requested zones. It is important to note that classification does not necessarily reflect existing groundwater quality, but rather the intended level of protection based on use and vulnerability.This dataset is maintained by the New Hampshire Department of Environmental Services (NHDES) and supports regulatory review, local planning, source water protection, and public health initiatives.Attributes:PERIMETER: Calculated perimeter of the classified area polygon.Local_Ent: The local entity (e.g., town, water supplier) managing the GAA.A_Reclass: Indicates whether the area is administratively reclassified.Contact: Primary contact person for the area’s groundwater program.Address: Mailing address for the responsible party or organization.Shape.STArea(): The geographic area in square units.Shape.STLength(): The perimeter length of the classified area.arcgis_core.DBO.Groundwater_Classification_Areas_GAA.AREA: Recorded area measurement, typically in acres or square feet.OBJECTID: System-generated unique identifier.

This United States Geological Survey (USGS) web map displays the National Watershed Boundary Dataset (WBD). It defines the perimeter of drainage areas formed by the terrain and other landscape characteristics. The drainage areas are nested within each other so that a large drainage area (Upper Mississippi River), will be composed of multiple smaller drainage areas like the Wisconsin River. Each of these smaller areas can be further subdivided into subsequently smaller drainage areas.The intent of defining hydrologic units (HU) for the WBD is to establish a base-line drainage boundary framework, accounting for all land and surface areas. The WBD is a comprehensive aggregated collection of HU data consistent with the national criteria for delineation and resolution. Each HU is identified by a unique hydrologic unit code (HUC). This service includes HU boundaries for HUC2 (Hydrologic unit boundary), HUC4 (Region), HUC6 (Subregion), HUC8 (Basin), HUC10 (Sub-basin) and HUC12 (Watershed). Pop-ups include HUC name, HUC code and the states that are included in each HU.More information about the WBD can be found at the WBD information site.Click here for information on the Federal Standards and Procedures for the National Watershed Boundary Dataset.Data for this service can be found here._Other Federal User Community federally focused content that may interest youDepartment of the Interior U.S Geological Survey
