We need more info, datum and projection.

Using supposed wgs84 datum and lat/lon projection, you have this map with OruxMapsDesktop -_>http://www.oruxmaps.com/Orla_perc.zip

It has an error of 50-70 mts.

Hi,
I was thinking that information from the picture (lat/lon in the corners) should be enough.
Need I to know which datum I should use to correct calibration?
Question is where can I find that information.
Thanks for your support, you are great! :-)

Hi; if you want to decrease the error to 3-5 mts. yes.

But for normal activities (tracking,...) it should be enough.

Where did you find the map?

You can try with local datums. For example, in Spain 99% of maps are wgs84 or European 1950 datum.
