In addition to EtakGuide there is also the Tiger map system at the Census Department. But they are both US only systems. tiger.census.gov/cgi-bin/mapbrowse-tbl www.etakguide.com I recently checked and both Map Quest and Map Blast are lacking this useful feature. When using a generic lat/lon for a city you may have to worry about the finite extent of the city. There are a few US cities that not only cover a large area but also are highly asymetric. Kansas City Mo., Tulsa, both of the Twin Cities come to mind. So it can be important to know just what point within the city is used for the city's lat/lon in a table. In the US it has traditionally been the city's main post office. Except sometimes it's the airport. Hay, it matters to someone who lives there! I guess the important thing is that sites like Chris' prediction service do allow the user to input their own coordinates. The best source (non electronic) for coordinates are indices and maps from the aviation community. Extensive lists of airport coordinates throughout the world have been compiled and should be available in most major public libraries of the world. There is also a series of reginnal and tactical flight planning maps covering virtually the entire world at 1:500K and much of it at 1:250K. I have found that this series of maps can be the best starting point when trying to get detailed coverage of someplace 'exotic' because of their large scale and uniformity of global coverage. In the industrialized world they can be obtained through most map stores (but plan on a special order). In the US they can be ordered directly from... I think it's the Defense Mapping Agency. Can also contact local airports. They will stock maps for only their own areas, but could give you pointers where to find other areas. On Wed, 20 Jan 1999, Mark A.
