I think you have an obligation to cite whenever possible. There are many ways to indicate the value-addition that you have provided, without neglecting to give credit to your inputs. If a map or table that I produce for publication draws in any substantial way from someone else's primary dataset, I might cite something like this within the text:
Source: Author's calculation, based on CIESIN/IFPRI/WB/CIAT (2006).
Or
Source: Authors, based on source data described in Box 1
or something like that, with the full citation in the references section of the document, including any links or contact information of the data-producing institution, e.g.
Center for International Earth Science Information Network (CIESIN), Columbia University: The International Food Policy Research Institute (IFPRI): The World Bank: and The International Center for Tropical Agriculture (CIAT), 2004. Global Rural-Urban Mapping Project (GRUMP): Urban Mask - Downloaded from: http://beta.sedac.ciesin.columbia.edu/gpw/ on 15 January 2007.
By the way, on the question of *how* to cite, check out http://sedac.ciesin.columbia.edu/citations/CitationGuidelines.html for a very helpful guide, based on standard guidelines for different types of data and their status (e.g. whether they are or not part of a published collection).

Jeremey, I'm going to come at your question from a slightly different direction. My purpose for citing sources is two fold: 1. I want to give credit where credit is due (didn't plagerize)and I want to show the validity of my data sets and the analysis based upon them (I used data at the appropriate scale and from a reliable source).
Much of the work I'm currently doing is used by scientists that know nothing about GIS or cartography. Their back ground is in chemistry, soil science, hydrology, etc... That's their area of expertise. However, the maps I generate are used as an integral part of their decision making process and they need to know that the data is reliable and that the analysis I have provided them can be defended if need be.

Thanks for your replies on this matter Dick and Andrea. You give a good
example Andrea!
I didn't want to give the impression that I wanted to "get away with" anything, or "re-engineer the stolen car".
What I was trying to get at is what Andrea mentioned with the derivative/updated data. I would have thought that this would be a very
common question among GIS'ers.
Thanks again!
