How about using the correct projection for your DWG files?
None of your DWG files are in the correct location. SHP files are fine, but the DWG files do not work. Can you please correct this as it would be very useful.
The northings seems to be correct but the eastings are way out of whack.
That being said, I am super impressed with Calgary's offering of open data. Edmonton still charges for their data. I have spoken to their city manager and they admit that the business model is not ideal.
Thank you for your feedback about our open data program. I will discuss the differences between the DWG and SHP files with our geospatial team and get back to you.
