Geospatial PDF files are PDF documents that contain geospatial information such as real world location and/or GIS attributes. Geospatial PDF documents can be created in many GIS applications such as ArcGIS and Mapinfo and from within Adobe Illustrator and Adobe Photoshop with the aid of the MAPublisher and Geographic Imager plug-ins, respectively. The geospatial data contained in a geospatial PDF document may be accessed and used (for example to locate a specific point or measure distances) without the aid of any additional plugins, using tools found natively in Adobe Reader 9 and Acrobat 9.
GeoTIFF and JPG formats are also supported. GeoTIFF is a commonly used image format to store geospatial information. JPG format doesn't store geospatial or coordinate system information, so it must have external reference files: either TFW & PRJ or JGW & WKT. All three files must be placed in a ZIP file when importing to Avenza Maps.
