Title: Course of the River Mississipi, from the Balise to Fort Chartres; taken on an expedition to the Illinois, in the latter end of the year 1765. By Lieut. (John) Ross of the 34th Regiment: Improved from the surveys of the river made by the French. London printed for Robt. Sayer, no. 53 in Fleet Street, published as the Act directs, 1 June 1775 (Raster Image)

Summary: This layer is a georeferenced image of a map of the Mississippi River, originally created by Lieut. Ross in 1775. The original map appears in "A general atlas, describing the whole universe: being a complete collection of the most approved maps extant; corrected with the greatest care, and augmented from the latest discoveries. The whole being an improvement of the maps of D'Anville and Robert. Engraved in the best manner on sixty-two copper-plates, by Thomas Kitchin, Senior, and Others. London: printed For Robert Sayer, no. 53, Fleet-Street, (1790)."The historic map layers in the Google Earth Rumsey Map Collection have been selected by David Rumsey from his large collection of historical maps, as well as some from other collections with which he collaborates. All the maps contain rich information about the past and represent a sampling of time periods, scales, and cartographic art, resulting in visual history stories that only old maps can tell. Each map has been georeferenced by Rumsey, thus creating unique digital map images that allow the old maps to appear in their correct places on the modern globe. Some of the maps fit perfectly in their modern spaces, while othersgenerally earlier period mapsreveal interesting geographical misconceptions of their time. Cultural features on the maps can be compared to the modern satellite views using the slider bars to adjust transparency. The result is an exploration of time as well as space, a marriage of historic cartographic masterpieces with innovative contemporary software tools.

Title: Transgressive Contours: Bolinas to Pescadero, California, 2010
Contributors:- Line data
- 2014
Summary: This line shapefile contains transgressive contours at 5 and 10 meter intervals for the areas within the 3-nautical mile limit between Bolinas and Pescadero in California. As part of the USGS's California State Waters Mapping Project, a 50-m grid of depth to the transgressive surface of the last glacial maximum was generated for the 3-mile offshore region. The resulting grid covers an area of approximately 550 sq km. The depth to the transgressive surface of the Last Glacial Maximum ranges between 4 and 78 meters. This layer is part of USGS Data Series 781. These contours are published in Scientific Investigations Map 3306, "California State Waters Map Series--Offshore San Gregorio, California (sheet 9). In 2007, the California Ocean Protection Council initiated the California Seafloor Mapping Program (CSMP) to create a comprehensive seafloor map of high-resolution bathymetry, marine benthic habitats and geology within the 3-nautical-mile limit of California's State Waters. CSMP has divided coastal California into 110 map blocks, each to be published individually as United States Geological Survey Open-File Reports (OFRs) or Scientific Investigations Maps (SIMs) at a scale of 1:24,000. Maps display seafloor morphology and character, identify potential marine benthic habitats and illustrate both the seafloor geology and shallow (to about 100 m) subsurface geology. Data layers for bathymetry, bathymetric contours, acoustic backscatter, seafloor character, potential benthic habitat and offshore geology were created for each map block, as well as regional-scale data layers for sediment thickness, depth to transition, transgressive contours, isopachs, predicted distributions of benthic macro-invertebrates and visual observations of benthic habitat from video cruises over the entire state. These data are intended for science researchers, students, policy makers, and the general public.

Summary: This layer is a georeferenced raster image of the depth to transition (base) map of uppermost Pleistocene and Holocene sediments in the region of Salt Point to Drakes Bay in California. As part of the USGS's California State Waters Mapping Project, a 20-m grid of depth to the transgressive surface of the last glacial maximum (LGM) was generated for the areas within the 3-nautical mile limit between Bolinas and Pescadero. Information for the depth to base of the post-LGM unit was generated by adding sediment thickness data to water depths determined by multibeam bathymetry. The resulting grid covers an area of approximately 550 sq km. The depth to the transgressive surface of the LGM ranges between 4 and 78 meters. This layer is part of USGS Data Series 781.

Summary: This line shapefile depicts geologic folds within the offshore area of San Gregorio, California. The offshore San Gregorio map area lies about 15 to 25 km southwest of the San Andreas Fault, the dominant structure in the distributed transform boundary between the North American and Pacific plates. The map area straddles the right-lateral San Gregorio Fault zone, a prominent structure west of the San Andreas Fault in the broader San Andreas Fault system. The San Gregorio Fault zone occurs predominantly in the offshore and extends 400 km from Point Conception on the south to Bolinas and Point Reyes on the north (Dickinson and others, 2005), coming onland at coastal promontories such as Pescadero Point in the map area and Pillar Point, a few km north of Half Moon Bay (sheet 9). In the offshore, the San Gregorio Fault system forms a distributed shear zone about 2 to 4 km wide that includes two main diverging fault strands. The western strand (also known as the Frijoles Fault) extends offshore from Pescadero Point. The eastern strand (also known as the Coastways Fault or Seal Cove Fault), is mostly onshore in this map area. Cumulative lateral slip on the San Gregorio Fault zone is thought to range from 4 to 10 mm/yr in this region (U.S. Geological Survey, 2010). The western strand of the San Gregorio Fault zone (i.e., Frijoles Fault) forms the eastern boundary of the Pigeon Point high. A map that shows these data is published in Scientific Investigations Map 3306, "California State Waters Map Series--Offshore of San Gregorio, California." This layer is part of USGS Data Series 781. In 2007, the California Ocean Protection Council initiated the California Seafloor Mapping Program (CSMP) to create a comprehensive seafloor map of high-resolution bathymetry, marine benthic habitats and geology within the 3-nautical-mile limit of California's State Waters.

This coverage can be used to to aid in assessments and mitigation of geologic hazards in the coastal region and to provide sufficient geologic information for land-use and land-management decisions both onshore and offshore.

Summary: This poygon shapefile depicts geologic features within the offshore area of San Gregorio, California. The continental shelf within California's State waters in the San Gregorio map area is shallow (0 to ~55 m) and flat with a very gentle (less than 0.5 degrees) offshore dip. Shelf morphology and evolution result from the interplay between local tectonics and sedimentation as sea level rose about 125 to 130 m over the last ~ 21,000 years (Lambeck and Chappel, 2001). Shelf deposits are almost exclusively sand (unit Qms) at depths less than 60 m and transition to more fine grained, muddy sediment (unit Qmsf) at greater depths in the southwestern most part of the map area. The boundary between units Qms and Qmsf was determined based on seafloor sediment samples (Reid and others, 2006) and video observations (sheet 6) from the Offshore of San Gregorio and adjacent map area. This boundary likely shifts seaward or landward based on seasonal to decadal changes in sediment supply, sediment transport, and wave climate. More coarse-grained sands and gravels (units Qmss and Qmsc) are primarily recognized on the basis of high backscatter (sheet 3). Unit Qmsc occurs as a nearshore, shore-parallel bar at typical water depths between 5 and 10 meters. Unit Qmss forms erosional lags in rippled scour depressions (for example, Cacchione and others, 1984) at water depths of about 25 to 35 m, in contact with offshore bedrock uplifts and unit Qms. Although the general areas in which unit Qmsc and unit Qmss occur are not likely to change substantially, the boundaries of the unit(s) are likely ephemeral, changing seasonally and during significant storm events. Unit Qmss deposits are common along this stretch of the California coast where offshore sandy sediment can be relatively thin (thus unable to fill the depressions) due to both lack of river input and to significant sediment erosion and offshore sediment transport during large northwest winter swells. Areas where shelf sediments form thin (< 2.5 m or less) veneers over low relief, undivided Cretaceous and (or) Tertiary bedrock are mapped as units Qms/TKu and Qms/Tp. These areas are recognized based on the combination of flat relief, continuity with moderate to high relief bedrock outcrops, high-resolution seismic-reflection data (sheet 8), and in some cases moderate backscatter. These units are regarded as ephemeral and dynamic sediment layers that may or may not be present based on storms, seasonal/annual patterns of sediment movement, or climate cycles. Tertiary deposits mapped in the offshore include two units of the Purisima Formation (units Tp and Tpt). The Purisima units are characterized by high backscatter (sheet 3) and distinct bedding recognized in multibeam imagery and/or seismic-reflection data (sheet 8). These Tertiary rocks are underlain by or in fault contact with Upper Cretaceous basement rocks, including sedimentary rocks of the Pigeon Point Formation (unit Kpp). The Pigeon Point Formation is mapped on the basis of high backscatter, massive and (or) rugged texture on multibeam imagery (sheets 1, 2), and reflection-free character on seismic-reflection data (sheet 8). Offshore outcrops of the Pigeon Point Formation form the offshore Pigeon Point high, a major structural feature that extends ~30 km to the northwest and represents the northeast boundary of the Outer Santa Cruz Basin (McCulloch, 1987). Areas where bedrock is exposed on the seafloor but there is less certainty regarding age are mapped as Cretaceous and Tertiary, undivided (unit TKu). Map unit polygons were digitized over underlying 2-meter base layers developed from multibeam bathymetry and backscatter data (see sheets 1 and 2, SIM 3306). The bathymetry and backscatter data were collected between 2006 and 2010. A map that shows these data is published in Scientific Investigations Map 3306, "California State Waters Map Series--Offshore of San Gregorio, California." This layer is part of USGS Data Series 781. In 2007, the California Ocean Protection Council initiated the California Seafloor Mapping Program (CSMP) to create a comprehensive seafloor map of high-resolution bathymetry, marine benthic habitats and geology within the 3-nautical-mile limit of California's State Waters.

Title: Cover Type Wetlands Map of the Oswegatchie-Black, Upper Hudson, and St. Regis Watersheds in New York State, 2000
Contributors:- Polygon data
- 2000
Summary: A set of 18 USGS 7.5' quadrangle-based wetland coverages was prepared for the Oswegatchie-Black, Upper Hudson, and St. Regis River watersheds, primarily within the New York State Adirondack Park using PC Arc/Info 3.4D+ at the Remote Sensing Laboratory, Plattsburgh State University (RSL). Wetlands were delineated on 1:40000 color infrared National Aerial Photography Program (NAPP) transparencies (for the Oswegatchie-Black watershed 1:58,000-scale National High Altitude Photography (NHAP) color infrared photos were used), transferred to orthophoto overlays using an Image Interpretations Systems Stereo Zoom Transfer Scope, and either hand digitized or scanned into PC Arc/Info format. A digital file extracted from the watershed data layer defined the outer boundary of the mapped area. This wetlands database consists of both polygon and linear features labeled using National Wetlands Inventory conventions. The 138 individual quadrangle files were exported to the New York State, Executive Department, Adirondack Park Agency (NYS APA) running Arc/Info version 8.0. The final MAPJOINED study area polygon coverage comprised of the 18 quad coverages was called STREGWTLND. Scale 1:24,000. The wetlands database is part of a larger database designed to help evaluate watershed/wetland relationships and provide data for cumulative impact assessments. The outreach efforts to share the Agency's natural resource database will encourage resource appreciation and wise use, particularly in a regional context. Supplemental Information: Line drawings for 18 quadrangle-based wetland coverages were scanned using an ANAtech Evolution scanner housed at the Adirondack Park Agency. Digital files were vectorized, transformed into the UTM coordinate system, edited, and attributed by the Remote Sensing Laboratory, Plattsburgh State University. Digital files were georeferenced into a digital quadrangle file containing four bounding tics using PC Arc/Info 3.4D+. Maximum allowable RMS was 0.003, snapdistance 20.0 meters, snaptype closest, weed tolerance 3.0 meters, and a fuzzy tolerance of 1.219 meters. Hard copies of the digital coverage showing arcs, dangle nodes, and label points were carefully checked against the line overlay for digitizing or scanning accuracy. Wetland labels were added as label components using a digitizer menu customized for this project. A label overlay was placed over the line drawing, and arc and wetland labels were assigned on the digitizer. Wetland label columns were concatenated into a unified wetland label using dBase IV. A hard copy of the wetland coverage was made showing NWI wetland labels and each label was checked against the label overlay. Wetland labels follow the conventions established by Cowardin, L.M., V. Carter, F.C. Golet, and E.T. LaRoe. 1979. Classification of Wetlands and Deepwater Habitats of the United States. FWS/OBS-79/31. Office of Biological Services, U.S. Fish and Wildlife Service. U.S. Department of the Interior, Washington, D.C. 103 pp. Some modifications to the conventions were made to accommodate this project and are noted in the final project report. Files were transported to the NYS APA as Arc/Info export files (no compression) compressed with WinZip on 100 MB Zip disks.

Title: Adirondack Park Boundary, 1993
Contributors:- Polygon data
- 1993
Summary: Outer boundary of the New York State Adirondack Park. The data set was hand digitized from 1:24000 scale, 7.5 minute series planimetric, mylar original, New York State Department of Transportation maps. The digitized boundary was edgematched with older planimetric quadrangle delineations being snapped to newer adjacent quadrangles. The boundary was compared to the legal Park description (Environmental Conservation Law Section 9-0101); the "New York State Department of Environmental Conservation Division of Lands and Forests Adirondack Map" 1993 edition; a joint DEC/DOT 1:24000 scale mapping project to delineate original allotment lines (patents, townships, tracts, etc.) in Essex, Hamilton, Warren, Washington, and Saratoga Counties; and county Real Property Tax Maps. Where obvious discrepancies occurred, Adirondack Park Agency cartographers re-plotted the boundary at 1:24000 scale using visual reference points on the maps and then re-digitized. Certain sections of the boundary remain in question (see Notes.) Use as a clipping polygon or as a set of arcs delimiting the park.

Summary: This layer is a georeferenced raster image of the historic paper map entitled: Trolley wayfinder, birds eye view of trolley routes in New England, published by the New England Street Railway Club, 1904. This is a perspective map not drawn to scale. Covers eastern portion of New England from Lewiston, Maine, to Newport, Rhode Island. The image inside the map neatline is georeferenced to the surface of the earth and fit to the Massachusetts State Plane Coordinate System, Mainland Zone (in Feet) (Fipszone 2001). All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, or other information associated with the principal map. This map shows features such as steam railroads, electric railroads, parks, buildings, drainage, and more. Relief and some features are shown pictorially. Includes 7 insets. This layer is part of a selection of digitally scanned and georeferenced historic maps of Massachusetts from the Harvard Map Collection. These maps typically portray both natural and manmade features. The selection represents a range of regions, originators, ground condition dates (1755-1922), scales, and purposes. The digitized selection includes maps of: the state, Massachusetts counties, town surveys, coastal features, real property, parks, cemeteries, railroads, roads, public works projects, etc.
