Karrewiet: Dag van nationale rouw in Frankrijk Het is vandaag dag van nationale rouw in Frankrijk. Heel de wereld reageert geschockt op de aanslag op het kantoor van het tijdschrift Charlie Hebdo. De makers van dat tijdschrift zijn al eens bedreigd omdat ze met hun strips soms grapjes maken over de Islam of de profeet Mohammed tekenen.
World Sunlight Map Watch the sun rise and set all over the world on this real-time, computer-generated illustration of the earth's patterns of sunlight and darkness. The clouds are updated daily with current weather satellite imagery. The Mercator projection used here is one way of looking at the spherical earth as a flat map. Used since the 16th century for navigation, straight lines on this map can be used accurately as compass bearings but the size and shape of continents are distorted. Compare this with Peters, Mollweide or equirectangular projection maps. Also available is a semi-realistic view of dawn and dusk from far above the Earth, a look at the moon, and information about how this works.
Gridded Population of the World - GPW v3 Introduction GPWv3 depicts the distribution of human population across the globe. GPWv3 provides globally consistent and spatially explicit human population information and data for use in research, policy making, and communications. This is a gridded, or raster, data product that renders global population data at the scale and extent required to demonstrate the spatial relationship of human populations and the environment across the globe.The purpose of GPW is to provide a spatially disaggregated population layer that is compatible with data sets from social, economic, and Earth science fields.The gridded data set is constructed from national or subnational input units (usually administrative units) of varying resolutions.
Map Collections Home Page The Library of Congress Search by Keyword | Browse by Geographic Location Index | Subject Index | Creator Index | Title Index The Geography and Map Division of the Library of Congress holds more than 4.5 million items, of which Map Collections represents only a small fraction, those that have been converted to digital form. The focus of Map Collections is Americana and Cartographic Treasures of the Library of Congress. These images were created from maps and atlases and, in general, are restricted to items that are not covered by copyright protection. Map Collection Digital Maps The Harvard Map Collection is one of the oldest and largest collections of cartographic materials in the United States with over 500,000 items. Resources range from 16th century globes to modern maps and geographic information systems (GIS) layers. A selection of our materials has been digitally imaged and is offered both as true picture images and georeferenced copies. This Virtual Collection includes those maps and atlases that are available through the Harvard Image Delivery Service. Those maps that have been georeferenced are available through the Harvard Geospatial Library. Therefore, many of the maps listed will have two records, one for the image that is true to the original and the other a georeferenced image.
