PDF3D ReportGen and PDF3D.IO development SDK can be used to convert geospatial formats, such as ArcGIS ASCII grid files, to 2D or 3D PDF.

To convert a typical 1800x1800 tile, please follow these steps for a good 3D PDF :

  1. Load your desired input file and set a suitable output path for your PDF
  2. In case of PRC-HCT compression type, set 0.00001 as PRC tolerance, to reduce depth numerical truncation

  1. Under Geospatial controls:
  • set degree to meter conversion factor to 0.0003 (to make visual exaggeration of depth variations)
  • Select Degrees as XY Axes Unit (as ArcGIS XY units are in Lat-Lon decimal degrees)
