I need to calibrate a map, but its datum is unavailable at the PathAway Map Manager.
The datum is the CÓRREGO ALEGRE, broadly used in Brazil until 1969, when it was replaced by the SOUTH AMERICAN 1969 (SAD69).
It represents most part of brazilian maps and is always available at GARMIN and othe devices.
Why it is not present at the Map Manager?
I need to transform all the coordinates to WGS84 to be able to calibrate the map!
Is there any plug-in that features this datum?
How can I overcome this problem?
Thanks a lot,
