(ESRI) product originally developed for the US Defense Mapping Agency (DMA) using DMA data. We used the DCW 1993 version at 1:1,000,000 scale. The <a href="http://www.maproom.psu.edu/dcw/dcw_about.shtml#CHARTS">DMA data sources</a> are aeronautical charts, which emphasize landmarks important from flying altitudes. This explains why there is a separate aeronautical theme with all conceivable airports, yet why on some themes small islands and lakes are simply unnamed points. ESRI, in compiling the DCW, also eliminated some detail and made <a href="http://www.maproom.psu.edu/dcw/dcw_about.shtml#ASSUME">some assumptions</a> for handling tiny polygons and edgematching. Also, note that the completeness of the thematic categories present in each layer will vary. Please read the layer descriptions (through links in the following table). http://tags.library.upenn.edu/makerecord/url/12934 http://tags.library.upenn.edu/makerecord/url/12934 http://tags.library.upenn.edu/makerecord/url/12933 http://tags.library.upenn.edu/makerecord/url/12933 http://tags.library.upenn.edu/makerecord/url/9611 http://tags.library.upenn.edu/makerecord/url/9611 LeadDog creates and maintains GIS street and road maps for Iraq, the Middle East, Africa, Mexico, and the rest of Latin America.&nbsp; We offer GIS and postcode maps for virtually every country in the world. http://tags.library.upenn.edu/makerecord/url/5966 http://tags.library.upenn.edu/makerecord/url/5966 <font size="2" face="Lucida Sans Unicode">The SALB dataset is a global digital dataset consisting of digital maps and codes that can be downloaded on a country by country basis. In order to insure consistency from one country to another, the database uses an international border standard developed in the context of the UN Geographic Database. This dataset is downloadable at no cost from this website. Due to the difference in the quality of the documents compiled, the digital maps part of the dataset are more adapted for thematic mapping than for precise location or modeling.&nbsp;It is therefore recommended not to use this data at a <font color="#000000">scale below 1:1 000 000.</font></font> http://tags.library.upenn.edu/makerecord/url/3734 http://tags.library.upenn.edu/makerecord/url/3734 Twentieth century conditions in maps.<br /> http://tags.library.upenn.edu/makerecord/url/1939 http://tags.library.upenn.edu/makerecord/url/1939 <p>Create digital maps that display a wide range of cultural material by using place and time as a common element.</p><p> ECAI technical infrastructure illustrates the vision of sharing distributed data and using time enabled mapping tools.</p> http://tags.library.upenn.edu/makerecord/url/423 http://tags.library.upenn.edu/makerecord/url/423 EDINA is actively seeking global and regional geographic datasets which can be made available to the UK Higher and Further Education community. Many global datasets are now being published via web map servers and are accessible through the use of interoperability standards. EDINA have created a <a href="http://edina.ac.uk/maps/global.shtml#wmv"> Web Map Viewer</a>, which will allow anyone with Internet access to view geographic data available through web map servers around the World.
