Title: Sedimentary Environment, Hudson River estuary, 2004
Contributors:- Polygon data
- 2005
Summary: This dataset provides sedimentary environments of the Hudson River Estuary from Verrazano Narrows Bridge to Troy. Areas of the Hudson River shallower than 4 meters have not been surveyed and sampled completely. The sedimentary environment interpretation is based on the evaluation of Chirp sub-bottom acoustic profiler data in conjunction with acoustic backscatter and bathymetry data. It is subdivided into depositional, erosional, and dynamic classes that are further subdivided, depending on the details identified in the sub-bottom data, or because of their location. A more complete description of this interpretation can be found in Nitsche et al. (2004) and Nitsche et al. (2005) In 1996, the New York State Department of Environmental Conservation (DEC) initiated an effort to map the benthic habitat of the Hudson River Estuary as part of a larger Hudson River Action Plan. This project includes extensive mapping using sidescan sonar, sub-bottom profiling, single and multi-beam bathymetric sonars, as well as collecting ground truth data with sediment cores, grab samples, and sediment profiling imagery (SPI). The goal of the project is the creation of a comprehensive data set that includes detailed interpretive maps of the physical environment of the floor of the estuary. An overview of the first phase of the benthic mapping project can be found in Bell et al. (2006)

Title: Sediment Type, Hudson River estuary, 2004
Contributors:- Polygon data
- 2005
Summary: This dataset provides sediment types found on the floor of the Hudson River Estuary. The sediment type interpretation is based on the grain size analysis of the cores and grabs with some guidance from acoustic backscatter data collected with sidescan sonar. Sediment profile imagery (SPI) has also been used to supplement these interpretations. Since the first guide in developing this interpretation is contouring the results of the grain size interpretation there is deviation from the side scan images. In most research on sediments, grain size data is given in phi intervals rather than in microns, millimeters, or inches. One phi unit is equal to one Udden-Wentworth grade. Phi diameter is computed by taking the negative log of the diameter in millimeters. We have identified 9 major classes of sediment based on the Wentworth classification.

Title: Zoning Map, Millis, Massachusetts, 2000 (Raster Image)
Contributors:- Raster data
- 2014
Summary: This layer is a georeferenced raster image of the historic paper map entitled: Official zoning map of the town of Millis, Massachusetts, Earth Tech [for] Millis Planning Board. It was published by Earth Tech in 2000. Scale [1:12,000]. 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, index maps, legends, or other information associated with the principal map. This map shows features such as roads, railroads, drainage, cities and other human settlements, territorial boundaries, shoreline features, and more. Includes also zoning districts, planning board members, street names, and watersheds. This layer is part of a selection of digitally scanned and georeferenced historic maps from the Harvard Map Collection. These maps typically portray both natural and manmade features. The selection represents a range of originators, ground condition dates, scales, and map purposes.

- National Geophysical and Solar-Terrestrial Data Center
- United States National Oceanic and Atmospheric Administration
- United States Group on Earth Observations
Summary: The Nighttime Lights of the World dataset contains the first satellite-based global inventory of human settlements, derived from nighttime data from the Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS). The DMSP-OLS has the unique capability to observe faint sources of visible-near infrared emissions present at the Earth's surface, including cities, towns, villages, gas flares, and fires. NGDC has developed algorithms for producing georeferenced fire and nighttime lights prod System requirements: Geographic Information Systems (GIS) software that reads ESRI shapefile format.
