I have an older database at work and I've been asked to map the recorded GPS coordinates for each record. Unfortunately, I can't figure out the map coordinates that were recorded.
As an example, 1301 Calle Oriente in Milpitas California shows as:
06158991 and 01987998
If I look at google maps, 1301 Calle Oriente is 37.446687, -121.886884
Is there a website that I convert 06158991 and 01987998 to a map like google maps? Is this a valid mapping coordinate format? If so, please let me know what format this is.
