I have a coordinates that I would like to plot on Google Earth. The coordinates I have appear to be in SAD69, a Brazilian projection. I need to convert them to latitude and longitude.
I tried importing into QGIS as a CSV file in SAD69 and then exporting as a CSV in WGS84. However, the coordinates I have do appear to be in the correct place. My point should be in central Brazil, however when open a SHP file of Brazil and add the point does not appear anywhere near Brazil at all.
The coordinates I have say:
SAD 69, MC 45° W
coordenadas Plano Retangulares Relativas, Sistema UTM: E=721320.945 e N =82009367.716
As I understand it, when importing the coordinates into QGIS,
E=721320.945 is my X coordinate and
N =82009367.716 would be my Y coordinate.
Do I need any other data?
I don't understand what
MC 45° W means in this context.
Based on the coordinates I have, using the SAD69 projection, the points don't seem to be in Brazil at all.
