I am using QGIS to open mrsid files from NAIP, clipping the part of the county that I need and using the "save as" option to export as a geotiff in state plane coordinates for use in Autocad. I am having a few issues with this method: First, the resolution on the image is not great. Second, the insertion point comes into Autocad correctly but when I close the image correlation dialogue box the image rescales for some reason.

I can rescale the image, but am wondering what I'm doing wrong?

  • You might want to show the original, transformed image, or give a bit more detail. May 22, 2016 at 6:42
  • It depends on CAD. Simplest way any of this family members understands is image rectangle shape, vector. Scale raster to opposite corners

As an alternative to Save As ..., you can try Raster -> Conversion -> Translate. It allows you to rescale the output as well.

If you need a different coordinate system, you have to use Raster -> Projections -> Warp.

I'm not sure what units of measure Autocad uses, QGIS uses degrees, meters or feet, depending on the layer's CRS. You can create a custom CRS that uses other units if needed.
