Hi there,
I have tried this from both Civil3D and standard AutoCAD. I have tried both 2018 and 202 AutoCAD. I'm in Australia which may be impacting this since there is a transition to GDA2020.
I am exporting an image as a Geotiff using Raster Designer which I would like to then import into a GIS platform (QGIS)
Here is my process in standard AutoCAD:
01) Attach an image (using reference dialogue)
02) Set the geographic position using Insert menu - set location from Map - dropping a pin and selecting coordinate system MGA 55 to GDA94 (epsg 28355). (Lat -37.817, long 141.967 ish)
03) Open Raster Tools - export image as a tiff and I enter the epsg code for the file horizontal coordinate system
04) The image can be brought into QGIS - but I cannot make it appear in the right place (it is off the West Coast of Africa).
04) When I open the world file coming out of Raster Design with the Geotiff I have the following data:
125.72152520478357
0.00000000000000
0.00000000000000
-125.72152520478355
3163.81500374053621
141527.92832487361738
05) - I cannot make much sense of this as the above process is a workflow I have used in the past and has worked fine - but maybe I am missing a step?
It seems the exported Geotiff is in relation to an arbitrary 0,0 point .....Can anyone identify what am I doing wrong?
Thanks!
