British Library Launches Crowdsourcing Map Georeferencing Program

The British Library has launched a pilot project to engage the public’s help in geoferencing historical maps.  A  sample of 725 maps of England and Wales from the 18th and 19th century (from the Ordnance Survey Drawings, 1780-1840) along with with large-scale street plans of London from  1560 to 1860 (from the the Crace […]

Analysis Finds Three Times More Farmers’ Markets in Areas with the Lowest Obesity Rates

An independent analysis conducted by mapping analytics firm PetersonGIS shows that locations with the highest obesity rates contain the fewest farmers’ markets. To produce the analysis, March 2011 data from the US Department of Agriculture (USDA) on market locations throughout the United States were mapped and correlated with county-aggregated obesity statistics* […]

Where to Look for Historical Maps

The use of extracting data from old paper maps is growing in popularity as a method to understanding historical geography.  David Ramsey popularized the method of georectifying historical maps and draping those maps over a DEM to create a 3D view.    Pastmapper is a project that digitizes historical maps in […]

WorldMap: An Open Source Software Platform

Harvard’s Center for Geographic Analysis recently released WorldMap, an open source mapping application designed to make it easier for researchers to upload large GIS datasets and to create online maps using thousands of geographic layers available to them from the Worldmap Library. WorldMap is built using open source software (access the WorldMap […]

Wind and GIS

GIS  has many applications in wind mapping, analysis and modeling. Geographic data and modeling of wind performance can help site wind turbines.  Study of wind patterns also is used for assessing wind damage potential. The GIS staff at the National Renewable Energy Laboratory provides both national wind resource assessment of the United States […]
