Does a PDF contain geographical coordinates if the Adobe Reader Geospatial Location Tool doesn't write anything?

I mean that I am moving the mouse over the pdf and no latitude and longitude values will show.

Does this mean there are no coordinates stored in the map?

When Adobe Reader Geospatial Location Tool doesn't show the Latitude and the Longitude, that means the geographical coordinates are not stored in the pdf map.

To convince yourself that your Adobe Reader is working well, please, use this pdf

After opening the pdf, you may go to Edit/Analise/Geospatial Location Tool and move the mouse cursor over the map. In the right-bottom corner you must to see something like this:

There are two ways for storing the geolocation info into PDF. One is called "Adobe Supplement to ISO 32000" while the other is "OGC GeoPDF Encoding Best Practice Version 2.2 (08-139r3)". The location tool of Acrobat Reader finds the coordinates if they are stored by using the ISO 32000 way but not necessarily if the other system is used. Terrago toolbar add-on can show also the GeoPDF (tm) coordinates. Gdalinfo utility can tell you if PDF has coordinates or not. You can also create geospatial PDF files with GDAL.
