For example, a common interrupted map is Goode's Homolosinusoidal (obviously seen in Goode's World Atlas-Rand McNally). Occasionally, the sinusoidal projection is intrupted like an orange peal which, IMHO, could be called gores. There are several interrupted projections in Snyder/Voxland's "Album of Map Projections." Often an interupted map is given a new name even though is is merely an operation of interrupting an existing projection. Gerald (Jerry) I.

A graduate student wants to find a world map shown on gores. The only example we could find was a small illustration in The Times Atlas of the World (1983 ed). We have looked in various cartography books, books on map projections and other atlases - no luck. Is this an actual map projection? If so, what is the name? She would like to either purchase a copy of the map or get a photocopy as long as the copy is at least 11x17. Susan Goodman [log in to unmask] I do remember there was an article at least two years ago in Geographic Information Systems about gores; alas, I saved it out of interest, but it is stratified in my inter-move storage. Maybe Denny Parker remembers it. A "gore" is a mathematical shape somewhat like the spinnaker of a sailboat. I suppose any surface at all could be used for a map projection. My question is, "Why does the grad student want an off-the-wall projection?" {} {|} FQDN:[log in to unmask] {*|} {^}} {{* }}\___/{{*}} Big Cypress National Preserve { __ __ }}} U.S.National Park Service { <!> <!> } Snailmail: HCR 61 Box 110 {{{ /;.;\ }} Ochopee, Florida 33943 USA {{ 0%%%0 }> Bellmail: (941) 695-2000 ext.28 {{/ / *|* \\ \}> ccMail: [log in to unmask] {{ // ___ \\}\ {// <III> \}\\ There are only about forty two Florida Panthers //// \\\\ still alive in the South Florida Everglades.... //({(__}}}\\ ____message cut___
