Hello.
I Have system save geo coordenates (X and Y) in my table ORACLE.
I want script php convert UTM22 SAD 69 for wsg84 (used in googlemaps).
I go receive value X and Y via variables $x and $y
Sample, rapid.
I have a website where I use PHP code to transform coordinates from Romanian system Stereo70 to WGS84 and then mark the point on Google Maps. I presume that there are some transformation algorithm that will make the change from SAD69 to WGS84.
Take care.
