Setup User Defined Local Coordinate System

[Anonymous]

Can some give me step by Step Instructions to setup a Local Coordinate System for Civil 3D 2019? or Possibly set it for me and export and send me the file?

I have attached the Parameters of the Site Calibration to this post.

Which state?

It's for a coordinate system in Alberta, Canada

Greetings my friend from the north!  

I'm not an expert in Canadian systems, but this video should point you in the right direction.  This first video is related to a lambert conformal projection, but note there is a link in his description for another option to handle a Transverse Mercator situation.  I hope this helps.

Thanks for the video, but this is not really helping me.  

My coordinate system in question has completely arbitrary coordinates  (N50,000', E50,000') if compared to UTM zone 12N. There is also a significant rotation in the system as well. (around 32 degrees).  I have already figured out how to start a user defined system, but given my parameters, i'm not sure how to proceed from there.

I attached all the parameters of the system in my first post in a PDF file.  

My ultimate goal here is so that I can reference geolocation map imagery correctly to my drawing.

Thanks for your help.

Andrew,
This looks like the same sort of site calibration I used to do with Trimble's Survey Controller. A site calibration would minimize residuals between GPS RTK shots taken on local control points, basically rubbersheeting a local projection. Civil 3D won't do a site calibration. Trimble Business Center will, but none of that data will then be useful in C3D.

If you guess at a >>>Map Projection<<< and then use the Transformation Tab for the Translations North and East and the Rotation, you might get close. But for that "Inclined Plane" Vertical Adjustment, you're out of luck in Civil 3D.

My advice: Do over. Go collect your data again.

Thanks for the response,

I'm not looking to do any coordinate transformation to another coordinate system, or any vertical transformation. Anything the surveyors shoot and record in the local system needs to stay and been shown in that system. But it would be nice to show some background satellite imagery for reference.

I'm simply looking to be about to load referenced imagery (such as Bing Maps) into my drawing and the imagery is correctly place and orientated to match my local site coordinates.

This short video is one method to align Bing Imagery to an assumed coordinate system, but ideally you would have Site control points (in both assumed and the published system) to verify.

Take this video for example https://youtu.be/oWqfIcVcQms

She is doing something similar to what i need with one exception. My system has a rotation. I dont see that option. Nor do i know what projection and other parameters i need to enter to make this work.

This may work...Will it work with a WMS (Web Map Service) as well? I'll try it out when i get back to the office. ill make as a solution if it works

I’ve only tried this successfully with Bing Imagery, but I assume it should work via a WMS Map 3D connection as well.  Good luck.

Andrew,

Here's my best guess/attempt at what you want to do. It's a two-stepper. Create a >>>custom coordinate system<<< from a modified >>>Alberta 3TM CS<<< and then use the >>>Transformation Tab<<<. Drawing attached. Can you post some data for testing?

This works with Bing Imagery, but not with Web Mapping Service. But it'll do for now...Thanks
