Etats Unis de l'Amerique Septentrionale
by Charles François Delamarche, published by Antoine Boudet in Paris in 1785.
Detail from map
This map captures the state of affairs in the short period between the Treaty of Paris in 1783 and the formation of the Northwest Territory in 1787. When the United States successfully broke with Great Britain it consisted of 13 states and a considerable amount of unorganized territory. The exact boundaries of the states, especially their western boundaries, were quite imprecise.
The text mentions 10 new states to...Continue reading "New in the Map Library: Etats Unis de l'Amerique Septentrionale, 1785"...
The MSU Map Library presents “Canada, ou Nouvelle France, &c.” by Nicolas Sanson, engraved by Jean Somer, published by Pierre Mariette in Paris in 1656.
This large hand-colored map represents important advances in European understanding of Great Lakes geography. It was the first map to draw and label all five Great Lakes in recognizable form. Lake Ontario bears an alternate name of Lac de St. Louys, and Erie also bears the alternate name ‘du Chat.’ Lake Huron is labeled Karegnon and Lake Michigan is known as Lac de Puans. Explorers had not yet reached the ends of the Great...Continue reading "Sanson 1656 map of Le Canada ou Nouvelle France"...
The MSU Map Library has added several new sets of digital topographic maps:
Ethiopia at 1:250,000 by the Ethiopian Mapping Agency YaʼItyoṗyā kārtā śerā derejet
Somalia at 1:250,000 prepared from Joint Operations Graphic series 1501 (JOGs)
Somalia at 1:200,000 by the Soviet mapping agency Главное управление геодезии и картографии при Совете Министров СССР
These new sets join our Ethiopian JOGs which were added in June 2012. All sheets are available in JPG preview, TIF, and GeoTIF. In the future we plan to add some sheets of Somalia at 1:100...Continue reading "Digital Topographic Maps: Somalia and Ethiopia"...
Landscan 2011 is a world population dataset at approximately 1 km resolution. It represents an ambient population (average over 24 hours). The LandScan algorithm uses spatial data and imagery analysis technologies and a multi-variable dasymetric modeling approach to disaggregate census counts within an administrative boundary. Since no single population distribution model can account for the differences in spatial data availability, quality, scale, and accuracy as well as the differences in cultural settlement practices, LandScan population distribution models are tailored to match the...Continue reading "LandScan Global Population 2011"...
Oversized scanning resumed in the Map Library with the acquisition of a HP T2300 scanner. Sheet maps up to 42" wide may be fed through and saved in TIF, JPG, PDF, JP2, or DWF formats. Bring your own USB drive, sorry it won't take external hard drives unless they have their own power source. Scans cost $1.
The MSU Map Library now has a fledgling inventory of licensed online digital topographic maps. Currently containing a single entry (Ethiopia JOGs at 1:250,000) over the summer you can watch this list grow with new entries!
MSU Libraries' first hosted-and-served set of digital topographic maps is of Ethiopia mapped at a scale of 1:250,000, prepared by the US Defense Mapping Agency Joint Operations Graphic. The finding aid linked from the library catalog displays the sheet boundaries and provides links to download jpg previews, 400 ppi TIF files, and 400 ppi GeoTIFF files.
Landscan is a world population dataset at approximately 1 km resolution (30" X 30"). It represents an ambient population (average over 24 hours). The LandScan algorithm uses spatial data and imagery analysis technologies and a multi-variable dasymetric modeling approach to disaggregate census counts within an administrative boundary. Since no single population distribution model can account for the differences in spatial data availability, quality, scale, and accuracy as well as the differences in cultural settlement practices, LandScan population distribution models are tailored to match...Continue reading "LandScan Global 2010 WebApp Access"...
The Map Library has a new look, with the service counter in a new location nearer the entrance. This change is part of a sequence of events that will eventually lead to a Geospatial Technology Area directly across from the service counter.
The MSU Map Library welcomes a new A3 scanner for flatbed scanning.
The Epson accommodates materials up to 12.2" x 17.2", will scan up to 2400 x 4800 ppi resolution and features 48-bit color. Flatbed scanning remains 5 cents per scan. The Epson complements our 42" HP roll scanner ($1 per scan) to enable scanning of bound publications and more fragile items.
