PostGIS adds support for geographic objects to the PostgreSQL object-relational database. In effect, PostGIS "spatially enables" the PostgreSQL server, allowing it to be used as a backend spatial database for geographic information systems (GIS)
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.
(description from website follows. generally, a good starting point to search for GIS data sets, including those pertaining to weather, climate, and renewable energy) geodata.gov is a web-based portal for one-stop access to maps, data and other geospatial services that will simplify the ability of all levels of government and citizens to find geospatial data and learn more about geospatial projects underway. This is part of the Geospatial One-Stop initiative, one of the 24 OMB electronic-government initiatives that will enhance government efficiency. The geodata.gov portal will accelerate the development and implementation of the National Spatial Data Infrastructure (NSDI) and includes state, local and tribal governments along with the private sector and academia as participants.
Homepage for the National Land Cover Data set, providing a landcover classification to every 30x30m portion of the United States. Also provides tree canopy cover data for the United States.
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.
Welcome to World Wind Geo: The Eclipse Geo browser. The Geospatial Web or Geoweb is a relatively new term that implies the merging of geographical (location-based) information with the abstract information that currently dominates the Internet. World Wind Geo is an experimental geo browser built on top of:
The U.S. Census Grids provide raster data sets that include not only population and housing counts, but a wide variety of socioeconomic characteristics. These gridded data sets transform irregularly shaped census block and block group boundaries into a regular surface – a raster grid – for faster and easier analysis.
A variety of tools for working with datasets. data visualization, mapping, blogs, data catalogs, R tutorial, web crawlers, data mashers, code, lists of projects, APIs, etc.
GeoCommons enables everyone to find, use and share geographic data and maps. Easily create rich interactive visualizations to solve problems without any experience using traditional mapping tools. GeoCommons provides a valuable data repository where GeoIQ customers can find and import data into their GeoIQ appliances.
POLYMAP koppelt unterschiedliche Geo- und Fachinformationssysteme (GIS) und bringt deren Daten in den Web-Browser. POLYMAP ist vollständig in Java geschrieben und wird unter einer Open-Source-Lizenz entwickelt.polymap.org bietet den Rahmen für Diskussion, Weiterentwicklung und Pflege des Basissystems und der Plugins. Plugins erweitern das System um praktisch beliebige Funktionen und bauen aufeinander auf. Plugins können von jedem entwickelt werden und sind nicht zwingend Open-Source
