Title: Sonar data skewed on map
Post by: 35wailin on June 22, 2017, 08:28:06 PM
I did some processing of raw data this morning on AC Pro.  I tried before and after updating the software, but my maps are skewed about 200m West of where they should be.  This places the sonar data on dry land.

Is there a setting to adjust the GPS positioning either in the Helix or on AC Pro?  Or is there another solution?

This might be a dumb question. But do you have the autocard card in your pc? This happens to me when I don't have the autochart card in my pc as it needs the LMMaster folder on the autocart card to access the baseline map files. This folder can also be copied to the pc.

It's not a dumb question.  And, no, i don't have the card in the computer.  I was trying to work with raw data that I copied from the card.  I will try in a few days againwith the card in the computerand see how that works.

Thanks for the possible suggestion.
