Just doing some research into geo-referencing a pdf file from a survey. It wouldn't have to be survey grade, maybe just tied to the address of the property..for research in house.

I thought my survey buddies would know how to find something that works.

Is this for your own records or client delivery? NM, I see now you said in-house.

If for your own records, I like to create folders for separate projects in Google Earth and then in the folder create a place mark & in the description pop-up (when you right-click the place marker) you can link to Google docs.

I have actually been using Corpscon to convert survey control to Lat/Long and linking it to the TGO report & OPUS solutions for a while now.

The other great benefit of this is if you get a GPS camera/smartphone, and use Google's picasa is that you can set the pictures to automatically geo-reference.

I use it as a sort of non-query-ing projects GIS.

I use ExpertGPS for stuff like that. It's $75. You would have to convert the .pdf to an image file (.jpeg, .tiff, etc.) & then you can easily import that into Expert. Then you need 2 or 3 control points, which I usually get from Goodle Earth (unless I have survey data). Once you've assigned them to points on the image you're in business. You can then toggle between your image and a topo map or aerial photo (both built into the software), and/or create waypoints from the image and load them into a handheld GPS, which I sometimes do with tax maps etc. for preliminary reconnaissance. You can also upgrade the software to handle GIS and/or CAD data, though at that cost level you'd want to seriously look into other options.

Expert GPS is actually $200 for commercial use, still a good deal, the $75 version is for Home/Non-Commercial Use.

GeoPDF by TerraGo is worth a look.
