Geospatial PDF

Adobe Acrobat Reader has supported layers since version 6. This provides a universal format for viewing GIS layers without having to install a GIS program. To turn layers on and off, access the Navigation Panel Layers tool. Note: Google Chrome uses its own pdf reader that does not support layers. Right-click and save the pdf for opening in Acrobat Reader.

Although not used by Acrobat, georeferencing meta data can be embedded in the pdf format to allow GIS programs to place a Geospatial PDF in its correct location. This can be useful in the field with GIS aware pdf viewers for smart phones - (iPhone/iPad: Avenza PDF Maps) (Android: TerraGo Mobile). KML paths can also be loaded in Google Earth and other GIS programs on smart phones or GPS units.

USGS is now releasing current and historic topo maps in GeoPDF format. You can download these maps from the USGS Store by using Map Locator to search for a location and then clicking on the red placemark to see the available downloads. For additional map related features for TerraGo supported pdfs, you can download and install the free TerraGo Toolbar for Acrobat.

Layer Tool
 

 

 

The following Geospatial PDF files were created with Global Mapper to illustrate the use of GIS layers to trace abandoned right-of-ways and other geographic & historic features. Use the layer tool in Acrobat to turn individual layers on and off. The geographic accuracy of the layers varies, so the right-of-way path is my best guess as to actual geographic location, even if it does not quite match with a specific layer. In many cases, I have not had the opportunity to check this information in the field, so actual locations could be off. Please contact me, if you have addition information that might improve their accuracy. Digital Elevation Model data and Topo maps courtesy of the USGS. Early Topo maps courtesy of Cleveland Public Library and other sources. Historic aerial photos courtesy of Pennsylvania Goeological Survey and Cleveland Public Library. Parcel information provided by the respective County GIS departments. KML/KMZ files can be opened in Google Earth.
