Calibrate chart to Gps?

[Algarve]

I need your help in my Opencpn the boat's location is slightly away from the exact spot on the chart.
How can i calibrate so the Gps boat location is as real as possible?

Pardon the bad English, I am using a translator.

there is always some error in the GPS.. you cannot add an offset as in some other location, the error may be in a different direction. You could check the specs on your GPS to see if there are more accurate models available

The position error is more likely caused by an inaccurate chart then the GPS. It looks like a CM93 cell, so read CM93 Offsets | Official OpenCPN Homepage
Of course make sure that your GPS is giving you a correct reading and the pier you are tied to really has the shape it shows on the chart before starting to freak out about every single chart cell you come across.

my apologies, I may have done to misunderstand, what I want is to calibrate the opencpn, is there any chance?

Algarve...
By calibrating OpenCPN you mean exactly what??? Each chart has a different error.

Hello,
I dont know if it is possible, but in the settings of the chart CM93 or in the software Open resolve the error location?

Please try to read CM93 Offsets | Official OpenCPN Homepage again and then try to use it. Is it what you mean by resolving the error?
