Historical Map of South / Central America from the David Rumsey Historical Map Collection

This dataset represents the international boundary between Canada and the United States.

This shapefile is a digital representation of the International boundary between the United States and Canada as per the Treaty of 1908. It has been generated from a combination of recent surveys and datum conversions. It is intended for mapping purposes only.

This world map shows the member countries and permanent observer countries of the Organization of American States (OAS).

The 2015 North American Land Cover 30-meter dataset was produced as part of the North American Land Change Monitoring System (NALCMS), a trilateral effort between Natural Resources Canada, the United States Geological Survey, and three Mexican organizations including the National Institute of Statistics and Geography (Instituto Nacional de Estadística y Geografía), National Commission for the Knowledge and Use of the Biodiversity (Comisión Nacional Para el Conocimiento y Uso de la Biodiversidad), and the National Forestry Commission of Mexico (Comisión Nacional Forestal). The collaboration is facilitated by the Commission for Environmental Cooperation, an international organization created by the Canada, Mexico, and United States governments under the North American Agreement on Environmental Cooperation to promote environmental collaboration between the three countries.The general objective of NALCMS is to devise, through collective effort, a harmonized multi-scale land cover monitoring approach which ensures high accuracy and consistency in monitoring land cover changes at the North American scale and which meets each country’s specific requirements.This 30-meter dataset of North American Land Cover reflects land cover information for 2015 from Mexico and Canada and 2016 for the United States. Each country developed its own classification method to identify Land Cover classes and then provided an input layer to produce a continental Land Cover map across North America. Canada, Mexico, and the United States developed their own 30-meter land cover products; see specific sections on data generation below.The main inputs for image classification were 30-meter Landsat 4-8 Collection 1 Level 2 data in the Canada and United States Maps(including Alaska) and 5-meters RapidEye for Mexico land cover map. Image selection processes and reduction to specific spectral bands varied among the countries due to study-site-specific requirements. While Canada selected most images from the year 2015 with a few from 2014 and 2016, the United States employed mainly images from 2016 with few images from 2015 and 2017. Mexico used all available 5-meters RapidEye images from January to December 2015, orthorectified as individual 25 by 25 kilometers tiles and the resampled to 30-meters pixel size.In order to generate a seamless and consistent land cover map of North America, national maps were generated for Canada by the CCRS; for Mexico by CONABIO, INEGI, and CONAFOR; and for the United States by the USGS. Each country chose their own approaches, ancillary data, and land cover mapping methodologies to create national datasets. This North America dataset was produced by combining the national land cover datasets. The integration of the three national products merged four Land Cover map sections, Alaska, Conterminous United States and Mexico.In this second version of the North America Land Cover map, the Alaska section has been updated from the map released in February 2020 (version 1). The United States Geological Survey (USGS) provided an updated land cover map of Alaska in July 2020, which was consequently integrated in the continental map and replaced the first version.

These data present geologic map units for the United States (Horton and others, 2017; Wilson and others, 2015) and Australia (Raymond and others, 2012) reclassified to 31 generalized sub-type lithologic groups of igneous, metamorphic, and sedimentary rocks (Lawley and others, 2022). These generalized classifications are based on interpretation of map unit descriptions in the different map compilations. Given that map unit descriptions often contain multiple rock types, there were subjective calls necessary when assigning generalized lithologic classification. The data were developed as part of the tri-national Critical Minerals Mapping Initiative (Kelley, 2020) between the United States, Canada, and Australia, an effort to model and map prospectivity for basin-hosted Pb-Zn mineralization. A national-scale geologic map compilation for Canada is not publicly available. Therefore, Lawley and others (2021) compiled geologic source maps to produce a gridded model layer that is provided in this data release in the Child Items section “Gridded geology shapefiles for the United States, Canada, and Australia.” References Horton, J.D., San Juan, C.A., and Stoeser, D.B., 2017, The State Geologic Map Compilation (SGMC) geodatabase of the conterminous United States (ver. 1.1, August 2017): U.S. Geological Survey Data Series 1052, 46 p., https://doi.org/10.3133/ds1052.

Contained within the 2nd Edition (1915) of the Atlas of Canada is a plate that shows five maps illustrating international and interprovincial boundary claims, circa 1915. Two show the Quebec - New Brunswick - Maine area, and another displays the Canada - Labrador boundary. There are two small maps showing offshore claims; one for the Bay of Fundy, and the other for the Gulf Islands (San Juan) in the Strait of Georgia. The Eastern Canada- United States boundary was commonly called the 'Marine boundary' from 1783 to 1842. There were still many disputes going on at the time, including jurisdiction of Newfoundland, the province of New Brunswick - Quebec and the United States, as well as Vancouver Island. The boundary indicating the Labrador coast was to be claimed by Canada. Major railway systems are presented on all maps.

The Mohorovicic discontinuity or 'Moho' maps the boundary between the earth's crust and mantle and is defined by an abrupt change in seismic velocity due to changes in the density of rocks between the crust and mantle. GeoTIFF grids that map depth to Moho (crustal thickness) for the United States and Canada, and for Australia are provided in this report and were used as evidential layers in developing prospectivity models for basin-hosted Pb-Zn mineralization (Lawley and others, 2022). A composite grid of Moho depths across the United States and Canada was created using data from Shen and Ritzwoller (2016) for the conterminous United States, from Zhang and others (2019) for Alaska, and from Schetselaar and Snyder (2017) for Canada. For this study, data covering North America were gridded onto a 0.25 degree grid and merged to create the composite grid across the United States and Canada. A grid of depth to Moho for Australia is from Kennett and others (2011). The GeoTiff grid of Mo ...

Contained within the Atlas of Canada 8.5x11 series maps is a map which was created as a joint effort by The Atlas of Canada, The National Institute of Statistics, Geography and Informatics, Mexico and the National Atlas of the United States under the sponsorship of the commission for environmental cooperation. The map shows the major North American drainage basins, or wateresheds, which drain into the Atlantic Ocean, Hudson Bay, the Arctic Ocean, the Pacific Ocean, the gulf of Mexico and teh Caribbean Sea. Each watershed is shown in its own colour, with subdivisions shown in tonal variations. Areas of internal drainage, which lack outlets to the sea, are shown in grey.
