<br>Subject: Re: [UMN_MAPSERVER-USERS] Vertor PDF as data source for mapserver<br>To: Barend Köbben <<a href="mailto:kobben@itc.nl">kobben@itc.nl</a>><br><br></span>I've tried some tools which convert PDF to DXF to ESRI shapefile, but the results are not really satisfactory, because by converting, some information is lost.
<br>The maps are created in Adobe Illustrator and the company creating the maps has provided me an .ai and a dwg file.
<br>But I haven't managed to make the dwg file work as a source of map server.<br>How do you do this? Do you use OGR? If I run ogrinfo on the dwg file, it tells me that it can't open it. Maybe, a special driver is needed to open the dwg file.

You'll need to do one or more conversions, depending on the software you<br>have available (eg. a way I use is to load the PDFs in Adobe Illustrator,<br>export them from there as AutoCad DWG/DXF and use that as a datasource).
<br><br>But whatever way, the main problem is the PDF has no georeferencing, ie. the<br>coordinates in it will be 'paper coordinates'. To have a usefull map, you'll<br>have to tranlate them to some menaingfull real world coordinates.
