How to import a Georeferenced Orthomosaic into AutoCAD

The georeferenced non transparent geoTIFF orthomosaic that Pix4Dmapper generates can be imported into AutoCAD. 

To import orthomosaic the following procedure needs to be followed:

  1. Drag and drop the orthomosaic into AutoCAD.
  2. Message asking for an insert point, scale factor and rotation angle will appear, press Enter three times. 
  3. Double click on the main window to zoom in to the orthomosaic.
  4. In command line type GEOREFIMG and press Enter.
  5. Select orthomosaic and press Enter.
  6. Double click on the main window to zoom in to the extents of orthomosaic.
 
Important: To import the orthomosaic, the GeoRefImg command needs to be installed on AutoCAD. To download the command: GeoRefIm.

In some cases due to the size of orthomosaics (500 MB to 1 GB and more), orthomosaics cannot be loaded into AutoCAD following aforementioned steps. BigTIFF format is used for large orthomosaic (merged tiles) in Pix4D as a it is not read by AutoCAD. In such cases, to open orthomosaic in AutoCAD:

A. Load each tile of the orthomosaic one by one in AutoCAD following aforementioned steps.

B. Use another third-party software like QGIS (open source) to save orthomosaic in traditional format:

  1. Open Quantum GIS.
  2. Drag and drop the non-transparent orthomosaic generated by Pix4D.
  3. Right click on the corresponding layer and click Save As...
  4. Once exported, drag and drop the new orthomosaic into the main view of AutoCAD.
  5. Message asking for an insert point, scale factor and rotation angle will appear, press Enter three times. 
  6. Double click on the main window to zoom in to the orthomosaic.
