There are two ways to store georeferencing into PDF. One is Adobe Supplement to the PDF standard ISO 32000, another is a system developed by TerraGo company but it is published as an open Best Practice paper by OGC. GDAL supports them both and links to corresponding original documents can be found from the PDF driver page http://www.gdal.org/frmt_pdf.html. In practice geospatial PDF means that geospatially enabled viewer can show the coordinates from any point on the map, possibly in many coordinate systems. In other way, viewer can take coordinates as an input and show the place. At least one viewer can even take the coordinates from GPS. GDAL PDF page > Keeping attributes.

I do not really understand how and where in the PDF file GDAL stores the attributes. They appear under the "Model tree" tab in Adobe Reader and system seems to utilize somehow the 3-dimensional features of PDF documents. For sure this is described in the 1310 pages long standard http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/pdf_reference_1-7.pdf I would guess that a faster way would be to ask directly from Even Rouault, the GDAL maintainer. -Jukka- > Thanks for your input. > > Michaël > > > > -Jukka- > > > > ________________________________________ > > Michaël Michaud wrote: > > > >> Hi Jukka, > >> Have you ever tried the pdf export function included in skyjump and > > compared with OGR tool. > > > >> I've no experience with it but know that SkyJUMP pdf export is one of > > the main plugins which > > has not been ported from SkyJUMP to OpenJUMP (and think there is > about > > one day work to do it). > > > > Michaël > > > >> Hi, > >> > >> Thanks.
