  1. Title: Roads Michigan 2009

    • Line data
    • 2009
    Contributors:

    Summary: This line data layer represents roads for Michigan in 2009. The dataset was originally published by the Michigan Center for Geographic Information on May 1, 2009.[This data set is part of the Michigan Geographic Framework. The framework serves as the digital base map for State of Michigan government. Currently the geographic framework contains features including roads, rivers, lakes, streams, railroads, political jurisdiction boundaries, school district boundaries, census area tabulation boundaries and legislative district boundaries. Specifically, this Michigan base map will consist of an Arc Info coverage which includes features and attributes based on the current TIGER/Line Files, base map features based on both the Michigan Department of Natural Resources (MDNR) Michigan Resource Information System (MIRIS) Files and an enhanced linear referencing system built from the Michigan Department of Transportation (MDOT) Michigan Accident Location Index (MALI). The Geographic Framework will serve as a common and standardized infrastructure on which all GIS users of 1:24,000 scale map data can build their applications. At the heart of the Geographic Framework will be the ability to administer programs that use location-based information and need to relate one database to another geographically. Version 9b replaces Version 8a as the current version of the Michigan Geographic Framework (MGF). A primary driving force in the creation of Framework Version 9b was the continued reconciliation of the road network and city/village boundaries with current information. Changes incorporated in version 9b of the MGF are described in the following documents: MGF_V9b_Updates, MGF_V9b_Trunkline_Updates These and other documents related to MGF can be found at: <http://www.michigan.gov/cgi/0,1607,7-158-12759_14194---,00.html> ]

  2. Title: Subwatershed Boundaries, California (12-digit HUC), 2013

    • Polygon data
    • 2014
    Contributors:

    Summary: This polygon shapefile contains the 6th level, 12-digit hydrologic unit code (HUC) sub-watershed boundaries of California. This layer consists of georeferenced digital data and associated attributes created in accordance with the "USGS National Map Accuracy Standards and the NRCS Federal Standards for Delineation of Hydrologic Unit Boundaries, 10/01/04." The dataset was developed by digitizing watershed and subwatershed boundary lines using 1:24,000-scale digital raster graphics (DRG), high-resolution digital watershed datasets, a high-resolution National Hydrography Dataset (NHD) at 1:24,000-scale, and 1:250,000-scale draft hydrologic boundary lines. A 30-meter National Elevation Dataset (NED) was used to produce the 1:250,000-scale preliminary draft boundaries, as well as a hillshade layer for additional reference. Some draft catchments (watersheds/subwatersheds) were also created with Watershed Boundary Dataset tools (ArcHydro Tools, Version 9), using the NED for terrain analysis and the NHD for determining stream flow direction. Polygons are attributed with the following: hydrologic unit codes for 6th level subwatersheds; HU sizes (in acres); states containing the HUs; non-contributing areas; downsteam hydrologic units; 5th and 6th level names; type of HUs (standard, frontal, etc.); flow modifications; and Geographic Names Information System (GNIS) identification numbers. The subwatershed hydrologic unit boundaries provide a uniquely identified and uniform method of subdividing large drainage areas. The smaller-sized 6th level subwatersheds (up to 40,000 acres) are useful for numerous application programs supported by a variety of local, state, and federal agencies. This data set is intended to be used as a tool for water resource management and planning activities, particularly for site-specific and localized studies requiring a level of detail provided by large-scale map information. This layer is part of a larger, seamless, nationally consistent geospatial database for the watershed boundary dataset. Wyoming Geographic Information Sciences Center. (2014). Subwatershed Boundaries, California (12-digit HUC), 2013. Wyoming Geographic Information Sciences Center. Available at: http://purl.stanford.edu/dq651jm0302. The definition for a hydrologic unit according to the FGDC Proposal, Version 1.0 - Federal Standards For Delineation of Hydrologic Unit Boundaries 3/01/02 states “A hydrologic unit is a drainage area delineated to nest in a multi-level, hierarchical drainage system. Its boundaries are defined by hydrographic and topographic criteria that delineate an area of land upstream from a specific point on a river, stream or similar surface waters. A hydrologic unit can accept surface water directly from upstream drainage areas, and indirectly from associated surface areas such as remnant, non-contributing, and diversions to form a drainage area with single or multiple outlet points. Hydrologic units are only synonymous with classic watersheds when their boundaries include all the source area contributing surface water to a single defined outlet point. “ This layer is presented in the WGS84 coordinate system for web display purposes.

    Contributors:

    Summary: This polygon shapefile contains the 4th level, 8-digit hydrologic unit code (HUC) sub-basin boundaries for California. A hydrologic unit is a drainage area delineated to nest in a multi-level, hierarchical drainage system. Its boundaries are defined by hydrographic and topographic criteria that delineate an area of land upstream from a specific point on a river, stream or similar surface waters. A hydrologic unit can accept surface water directly from upstream drainage areas, and indirectly from associated surface areas such as remnant, non-contributing, and diversions to form a drainage area with single or multiple outlet points. Hydrologic units are only synonymous with classic watersheds when their boundaries include all the source area contributing surface water to a single defined outlet point. The National Cartography and Geospatial Center (NRCS) modified the National WBD dataset with the intention of creating a seamless dataset for the entire country by all 6 levels. The data is delivered by sub-basin and includes data for HUC-8, HUC-10, and HUC-12. The deliverable includes attributes for hydrologic unit codes, hydrologic unit name, downstream hydrologic unit, man-made modifications to overland flow that alter the location of the HU boundary, and HU type for each hydrologic unit level 1-6. An acres field already exists for each subwatershed.This layer consists of georeferenced digital data and associated attributes created in accordance with the "USGS National Map Accuracy Standards and the NRCS Federal Standards for Delineation of Hydrologic Unit Boundaries, 10/01/04."

They show and name works of nature, such as mountains, valleys, lakes, rivers, vegetation, etc. They also identify the principal works of humans, such as roads, railroads, boundaries, transmission lines, major buildings, etc. Relief is shown with standard contour intervals of 50 meters, with some sheets having supplemental meter contours, form lines, hachures, shading, and/or spot heights. Depths shown by bathymetric isolines. Please pay close attention to map collar information on projections, spheroid, planimetric revision methods and dates, and keys to grid numbering and other numbers which appear inside the neatline.
