@RachelWikenMC @DavidOry I just want to make sure I understand the problem appropriately...the develop branch currently allows you to specify the output CRS for the network either when doing the write-out or in the parameters:

roadway_standard_to_met_council_network(self, output_epsg=None):

Is this not working? Or is this not part of the problem you need fixing?

DavidOry commented 2 years ago

Thanks @e-lo. The issue is not writing the network. The issue is:

  1. We make an edit in Cube and record a log file.
  2. Because the Cube network is in the model CRS, the log file records new nodes in the model CRS.
  3. Network Wrangler is expecting lat/lng CRS. So when the Project Card is read in, it fails.

For MTC, @i-am-sijia added functionality to write out the Project Card in lat/lng CRS.

Thanks @DavidOry , I was out yesterday. That correctly summarizes the issue. I need the create project card step to output in lat/long and not model CRS. Currently having to correct project cards by hand for new node coordinates.
