The Atlas describes and maps every change in the boundaries of all United States counties from the early 1600s to 2000. In addition, the atlas compiles and maps all changes in colonial or territorial and state boundaries, including the evolution of the states, plus county name changes, unsuccessful proposed counties, and attachments of unorganized counties and non-county areas to operational counties. In most cases, a separate map is available for each different county configuration. view maps or Download Historical State and County Shapefiles.

a tool that can convert geographic coordinate data from one format to another. If you're not a map nut, that's the challenge one might encounter switching, for example, from latitude and longitude to Universal Transverse Mercator--or from geocentric latit

CIESIN, the Center for International Earth Science Information Network, is a unit of the Earth Institute at Columbia University, based at the Lamont campus in Palisades, New York. CIESIN works at the intersection of the social, natural, and information sciences, and specializes in on-line data and information management, spatial data integration and training, and interdisciplinary research related to human interactions in the environment. CIESIN’s mission is to provide access to and enhance the use of information worldwide, advancing understanding of human interactions in the environment and serving the needs of science and public and private decision making.
The purpose of the Data Preservation WG is to provide a venue and mechanism for seeking technical and institutional solutions to the challenge of preserving digital geospatial data.
Delny is a Python package which can be used to make a Delaunay triangulation from a set of n-dimensional points. It is effectively a Python interface to libqhull, the C library of the Qhull program, but (currently) restricted to Delaunay triangulation. It was first developed to use in a mesh generator developed as dissertation at the University of Southampton with Hans Fangohr as supervisor. This very specific application area was the reason for the limited functionality of the libqhull wrapper, which in turn is likely the reason that there is useable code available.
This article provides an overview of Linux-based tools for Geographic Information Systems (GIS), including a quick take on the ESRI's ArcReader. Future articles will explore this and other individual tools in greater depth.
The international quarterly e-journal on sciences and technologies affined to history of cartography and maps.
Principal aim of the journal is: To couple issues on history of cartography and maps with a variety of possibilities offered by the new digital information and communication technologies. To bring together, in harmonic convergence, historians of cartography and maps, cartography scholars and experts in new digital cartographic technologies in order to create a common space of research targeting at the broadening of cartographic and map history access and expertise.
This journal is a pluralist peer reviewed international journal which does not obey any particular ideological, theoretical or methodological approach in dealing with humanistic, artistic, scientific and technological issues related to map history and cartographic heritage in the large.
