Map Block Accuracy


I am using Map Block to create database of Trees and Shrubs on large property.
I have successfully added gps co-ordinates and am getting the map to work, my problem is that everything seems to be shifted and fairly inaccurate.
I understand the limitations of accuracy, but I am pulling the cords from cloud google maps and using these and would expect them to match up with the map created in blocks.
It doesent seem to match up.
Is there a way to increase accuracy or at least have the same drift from cloud google maps to airtable maps block.
any suggestions would be appreciated.
