  1. Title: Glaciers, North America, 2004

    Contributors:

    Summary: This polygon shapefile shows areas of permanent ice found on the North America landmass including Greenland, and also shows areas of land found within glaciers. No distinction is made between major glaciers, ice fields, and the Greenland ice cap. The only permanent ice shown on land areas outside of North America and Greenland is on Iceland. This layer is part of the 1997-2014 edition of the National Atlas of the United States. The North American Atlas data are intended for geographic display and analysis at the national and continental level. The data should be displayed and analyzed at scales appropriate for 1:10,000,000-scale data.

  2. Title: Populated Places, North America. 2004

    Contributors:

    Summary: A joint venture involving the National Atlas programs in Canada (Natural Resources Canada), Mexico (Instituto Nacional de Estadística Geografía e Informática), and the United States (U.S. Geological Survey), as well as the North American Commission for Environmental Co-operation, has led to the release (June 2004) of several new products: an updated paper map of North America, and its associated geospatial data sets and their metadata. These data sets are available online from each of the partner countries both for visualization and download. The North American Atlas data are standardized geospatial data sets at 1:10,000,000 scale. A variety of basic data layers (e.g. roads, railroads, populated places, political boundaries, hydrography, bathymetry, sea ice and glaciers) have been integrated so that their relative positions are correct. This collection of data sets forms a base with which other North American thematic data may be integrated. Any data outside of Canada, Mexico, and the United States of America included in the North American Atlas data sets is strictly to complete the context of the data. The North American Atlas - Populated Places data set shows a selection of named populated places suitable for use at a scale of 1:10,000,000. Places, which refer to individual municipalities, are always shown using point symbols. These symbols have been fitted to the North American Atlas roads, railroads, and hydrography layers, so that the points represent the approximate locations of places relative to data in these other layers. The selection of populated places was based on local importance (as shown by population size), importance as a cross-border point, and, occasionally, on other factors. All capital cities (national, provincial, territorial or State) are shown for Canada, Mexico, and the United States of America. Attributes were added to the data to reflect population class, name, and capital. Cartographic considerations were taken into account so that names do not overlap in crowded areas, nor are there too many names shown for sparsely-populated areas. This layer is part of the 1997-2014 edition of the National Atlas of the United States. The North American Atlas data are intended for geographic display and analysis at the national and continental level.

  6. Title: Roads, North America, 2004

    Contributors:

    Summary: This line shapefile represents roads in North America at 1:1,000,000 scale. The roads included in this layer are either those that connect major centres of population or selected frontier roads. Roads under construction are not shown. There are three road classes: Major roads, which are divided, multi-lane, limited access highways; Secondary roads, which are all roads that do not meet the definition of major roads; and Ferries, which are major ferry links which run either year round or through periods when ice conditions permit. This data set was produced using digital files supplied by Natural Resources Canada, Instituto Nacional de Estadística Geografía e Informática, and the U.S. Geological Survey.

  14. Title: Water Table Contours Gogebic County, Michigan 2008

    Contributors:

    Summary: This line data layer represents water table contours for Gogebic County, Michigan in 2008. The dataset was originally published by the Michigan State University Remote Sensing & GIS Research and Outreach Services in 2008. Dates have been assumed based on the date the shapefile was last edited.[Individual county first water contour datasets represent the elevation of the first water (water table) in 10-foot intervals across the landscape. Each first water contour dataset was created using the contour function in ArcGIS Spatial Analyst, version 8.3.][Groundwater Inventory and Mapping Project, a cooperative effort between the Water Bureau - Michigan Department of Environmental Quality, USGS - Michigan Water Science Center and Michigan State University - Institute of Water Research, RS&GIS and Biosystems and Agricultural Engineering. This project was mandated by P.A. 148 (Michigan Acts of 2003). Major funding was provided by MDEQ, supplemented with additional funds from the USGS Cooperative Water Program.]
