I have a friend who posed this question to me, was hoping someone with a little more experience may help me answer.
"I have been doing a little work with the people in South Africa using ArcGIS. They mostly use it for mapping the locations of the dwellings that are in the surveillance site. That is, they project an aerial photo of the land and layer the XYs of the dwellings on top. Up to now, we have used .tiff images as the aerial background. But, these photos are outdated (ca. 2001). We are trying to obtain new images, but they are extremely expensive. However, we found one government office that is willing to give us .pdf images of the land for free. And this brings me to my question: Do you know if you can use project .pdf images in ArcGIS? If not, is there a way to convert .pdf images to .tiff images for use in ArcGIS? Or is there some information in "original" .tiff images that would be lost if we obtained them from .pdfs?" Thanks you in advance for any information, Peter _______________________________________________ Peter Graham UW Sociology Department Graduate Student _______________________________________________ Uw-gis-l mailing list [email protected] http://mailman1.u.washington.edu/mailman/listinfo/uw-gis-l
