The LandScan Global Population Databases, developed at the Department of Energy's Oak Ridge National Laboratory, represent resolution global population distribution databases available. This is a geographically based, population distribution model.
LandScan is a global population database that shows geographical distribution of population at one-kilometer resolution over an average 24 hour period.
The LandScan algorithm uses spatial data and imagery analysis technologies and the most up-to-date census data within an administrative boundary. Accurate administrative boundaries are an integral part of the LandScan population distribution modeling process. These population distribution models are tailored to match the data conditions and geographical nature of each individual country and region.
Most national censuses count populations by measuring where people sleep (or reside) rather than where they work or travel. LandScan integrates daytime movements and collective travel habits into a single measure to produce a better representation of where people are located during an average day.
With improvements added this year, high-resolution imagery sources were used extensively for validation to refine urban areas, land cover data, and thousands of smaller villages and populated places.

This collection from the University of Michigan Museum of Zoology Mammal Division includes page images and brief data records of a scrapbook comprised of maps of the state of Michigan, keyed to anecdotal reports of species in the state over time (primarily from the 19th and early 20th centuries). It is believed to have been created by N. A. Wood.
This is part of the Flora and Fauna of the Great Lakes Region: A Multimedia Digital Collection.
This collection contains map images showing the locations in which fish have been recorded in Michigan. The atlas contains separate maps for 153 species. Records are keyed to indicate whether a voucher specimen is available in the University of Michigan Museum of Zoology.
CultureGrams Online Database is a leading reference for concise, reliable, and up-to-date cultural information on countries across the globe. It includes four editions: the World Edition (for junior high school and up) and the Kids, States, and Canadian Provinces editions (for upper elementary school students). In addition to the country/state/province reports, the database includes the following features: images, slideshows, streaming videos, sortable data tables and graphs, interviews with natives from countries around the world, recipes for each country, and more. The World Edition includes 208 country-specific reports. These provide complete coverage of every sovereign country recognized by the United Nations, plus several foreign dependencies.
Each World Edition report is written by a native or long-term resident of the country in coordination with a CultureGrams editor. Writers are selected for their education, knowledge of a national language, experience with different regions and socioeconomic groups, recent residency in the country, and access to current information.
Sanborn maps are large-scale plans of American cities and towns, created 1867-1970. They were created to assist fire insurance companies to assess the risk associated with insuring a property. The maps were drawn at a scale of 50 feet to one inch. ProQuest Sanborn Maps Geo Edition provides geo-coding and indexing by address for a selection of Sanborn maps. Searching can be done by address or by latitutde/longitude coordinates. Maps from different years can be layered, including modern maps using the Google Map interface.
Eight states are included: Florida, Illinois, Massachusetts, Michigan, New York, North Carolina, Pennsylvania and Virginia.
Cities included: Baltimore, Boston, Charlotte, Detroit, Los Angeles, Miami, New York, Newark, Philadelphia, Richmond, Seattle and Washington DC.
For other all areas use Digital Sanborn Maps 1867-1970, without geo-coding.
