"The Atlas presents in maps and text complete data about the creation and all subsequent changes (dated to the day) in the size, shape, and location of every county in the fifty United States and the District of Columbia. It also includes non-county areas, unsuccessful authorizations for new counties, changes in county names and organization, and the temporary attachments of non-county areas and unorganized counties to fully functioning counties. The principal sources for these data are the most authoritative available: the session laws of the colonies, territories, and states that created and changed the counties"--About the project.

China Geo-Explorer is an intelligence spatial data service offered by the University of Michigan China Data Center, in collaboration with the All China Market Research Co., Ltd and the State Key Laboratory for Information Engineering in Surveying, Mapping and Remote Sensing (LIESMARS) of Wuhan University. It offers China demographic and economic data, maps, charts and reports in the web-based delivery system. With this spatial intelligence, users are able to make rapid, accurate spatial decisions with greater confidence for regional planning, business investment, population, housing, environmental assessment, public health and many other spatial applications. Data sources in this database includes demographic and business information for all PRC geographies, including 31 Provinces, 345 Prefecture Cities, 2,873 Counties, and over 50,000 Townships.

The Digital Atlas of Roman and Medieval Civilization (DARMC) makes freely available on the internet the best available materials for a Geographic Information Systems (GIS) approach to mapping and spatial analysis of the Roman and medieval worlds. DARMC allows innovative spatial and temporal analyses of all aspects of the civilizations of western Eurasia in the first 1500 years of our era, as well as the generation of original maps illustrating differing aspects of ancient and medieval civilization. DARMC's coverage begins under the Roman empire and extends nearly a thousand years toward the present by encompassing the medieval world. Although the initial post-Roman focus has been on medieval Europe, Byzantium and the Crusades have not been neglected, and we have begun to include the essential third leg of the tripod of medieval civilization, the Islamic world. DARMC contains dozens of data layers in several geodatabases, that is, databases whose data is georeferenced or specified in terms of decimal degrees of latitude and longitude.

At approximately 1 km resolution (30" X 30"), LandScan is the finest resolution global population distribution data available and 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 data conditions and geographical nature of each individual country and region.

ORBIS: The Stanford Geospatial Network Model of the Roman World" reconstructs the time cost and financial expense associated with a wide range of different types of travel in antiquity. The model is based on a simplified version of the giant network of cities, roads, rivers and sea lanes that framed movement across the Roman Empire. It broadly reflects conditions around 200 CE but also covers a few sites and roads created in late antiquity

"Our objective is to help visually analyze and understand the demography of the U.S. through the use of interactive maps and data reports. Our primary functions include Demographic Data Analysis, Interactive Map/Report Design and Software Development. Our main goal is to visually display the demographic change that has occurred in the U.S. since 1790 through the present, for the country over all down to the level of the county. For more recent years, one can display areas as small as your own neighborhood. Certain cities may even be displayed as far back as 1910. To do this we have developed a collection of interactive demographic maps that can be viewed, queried and manipulated on our site."
