This dataset describes Native American Ceded Tribal lands in Washington State. Boundary lines have been digitized from a variety of digital data sources including 1:100,000 streams for boundaries described in treaties as following a stream or river, 1:24k Water Resource Inventory Areas (WRIA), Watershed Administrative Unit (WAU) and Hydrologic Unit Code (HUC) boundaries for boundaries referred to in treaties as 'divide', 'summit' or 'between the waters of', 1:100,000 Major Public Lands (for current reservation areas), 10 meter DEM and 7.5 minute USGS digital Quad maps (to define ridgelines and 'divide' where WRIA, WAU or HUC boundaries don't exist) and NAIP orthophoto imagery (to get a feel for what a questionable...

TRIM-EBM is a 2D product containing TRIM 1 features excluding toponoymy, contours and DEM for which area based features have been closed to form polygons, symbol points have been replaced with polygons and vertical integration of streams has been removed 25 Meter Resolution Not available to the public for download. Must be purchased from BC Government
A pool, or group of pools, within a specified geographic area that contain oil or natural gas. Fields are not specific to producing geological formation(s). Fields are used for well naming purposes relative to the well site surface coordinates and the objective formation of the well.
ASTER is capable of collecting in-track stereo using nadir- and aft-looking near infrared cameras. Since 2001, these stereo pairs have been used to produce single-scene (60- x 60-kilomenter (km)) digital elevation models (DEM) having vertical (root-mean-squared-error) accuracies generally between 10- and 25-meters (m). The methodology used by Japan's Sensor Information Laboratory Corporation (SILC) to produce the ASTER GDEM involves automated processing of the entire ASTER Level-1A archive. Stereo-correlation is used to produce over one million individual scene-based ASTER DEMs, to which cloud masking is applied to remove cloudy pixels. All cloud-screened DEMS are stacked and residual bad values and outliers...
TEM_50K contains Terrestrial Ecosystem Mapping (TEM) polygons with key and amalgamated (concatenated) attributes derived from the RISC (Resource Inventory Standards Committee) standard attributes completed at a scale of 1:50,000 or smaller (i.e. 1:100,000). TEM divides the landscape into units according to a variety of ecological features including climate, physiography, surficial material, bedrock geology, soils and vegetation. TEM methods include manual air photo interpretation supported by selective field checking. This layer is derived from the STE_TEI_ATTRIBUTE_POLYS_SP layer by filtering on the PROJECT_TYPE and PROJECT_MAP_SCALE attributes. By accessing this dataset you agree to the Province's license available...
This data depicts highway locations in Alaska as digitized primarily from 1:24,000, 1:63,360, and 1:250,000 USGS quadrangles. The source document that represented the newest information and best geographic location was used to capture the data. All infrastructure from the primary source document was digitized and then supplemented with the information from other source documents for additional or updated infrastructure or attributes.
This data set contains boundaries and tags for major geologic units in Alaska, Hawaii, Puerto Rico and the U.S. Virgin Islands. In addition to the polygons representing the areal extent of geologic units, it identifies major faults and continental glaciation in Alaska. The data depict the geology of the bedrock that lies at or near the land surface, but not the distribution of surficial materials such as soils, alluvium, and glacial deposits. This map complements the Generalized Geologic Map of the Conterminous United States by Reed and Bush. The data are generalized from a compilation prepared for use in the Geologic Map of North America, published as a paper map by the Geological Society of America and...

Orthophotos combine the image characteristics of a photograph with the geometric qualities of a map. The primary digital orthophotoquad (DOQ) is a 1-meter ground resolution, quarter-quadrangle (3.75-minutes of latitude by 3.75-minutes of longitude) image cast on the Universal Transverse Mercator Projection (UTM) on the North American Datum of 1983 (NAD83).The geographic extent of the DOQ is equivalent to a quarter-quad plus The overedge ranges a minimum of 50 meters to a maximum of 300 meters beyond the extremes of the primary and secondary corner points. The overedge is included to facilitate tonal matching for mosaicking and for the placement of the NAD83 and secondary datum corner ticks. The normal orientation...
Digital file containing a bedrock geology polygon coverage for British Columbia. Polygon coverage of geology compiled at 1:100,000 scale as part of the B.C. Ministry of Energy and Mines, BC Geological Survey Branch mineral potential project, 1994-1996. Original coding revised and rationalized in 2001-2002 by D.G. MacIntyre, updated and revised in 2002-2004 by N.W.D. Massey. Coverage generalized on lithostratigraphic map unit (MAPLABEL) designation. New mapping completed after 1996 is being added to this file on an ongoing basis. Bedrock Geology - This theme consists of a single layer of bedrock geology polygons. Polygons depict the nature of the bedrock geology based on a compilation of all geologic mapping done...
The Department of Natural Resources, Geology and Earth Resources Division (DGER), also known as the Washington Geological Survey, actively identify, assess, and map landslide hazards using modern geotechnical and geophysical methods. Our hazard maps are critical for land-use and emergency-management planning, disaster response, and building-code amendments. As our population grows, there is increasing pressure to develop in hazardous areas, thus delineating these areas is imperative. In response to the Growth Management Act's mandate to use the 'best available science', our geologists meet with local governments and citizens in at-risk communities to educate about geologic hazards and ensure these hazards are taken...
NAIP horizontal accuracy specifications - From 2003 to 2004 the specifications were as follows: 1-meter Ground Sample Distance (GSD) imagery was to match within 3-meters, and 2-meter GSD to match within 20 meters of reference imagery. For 2005 the 1-meter GSD specification was changed to 5 meters matching to reference imagery. In 2006, all states used the same specifications as 2005 except for Utah, which required a match of +/- 6 meters to true ground. In 2007, all specifications were the same as 2006, except for Arizona, which used true ground specifications. In 2008 approximately half of the states acquired used true ground specifications and the other half used reference imagery. The 2008 states that used absolute...
Planimetric positional data represents a structuring of digitally scanned National Topographic Series mapsheet layers. Elevation data was created thorugh interpolation and extrapolation from the scanned contour layer. DATA SOURCE SIZE : 84 sheets GEO COVERAGE : Full coverage of province. Base information originates from digital scanning and vectorizing of federal 1:250,000 NTS lithographic layers of published mapsheets. DEM was created through a process of interpolation/extrapolation from original contours and the manual introduction of elevation points from hardcopy. Water and wetland closed polygonal features were created at a later date. Index Grid for NTS 1:250,000 scale maps.
The National Road Network (NRN) product contains quality geospatial data (current, accurate, consistent and maintained) of Canadian road phenomena. The NRN product is distributed in the form of thirteen provincial or territorial datasets and consists of two linear entities (Road Segment and Ferry Connection Segment) and three punctual entities (Junction, Blocked Passage, Toll Point) with which is associated a series of descriptive attributes such as, among others: First House Number, Last House Number, Street Name Body, Place Name, Functional Road Class, Pavement Status, Number Of Lanes, Structure Type, Route Number, Route Name, Exit Number. The maintenance of the NRN data is done within the framework of intergovernmental...
