Dear sir/madam:

First of all thank you for your cooperation. Dear sir/madam please kindly help me how can I convert the datum from Everest 1830 to WGS 84.

Thanking you.

### Mapping Center Answer:

You would do this by changing the coordinate system of the data using the Project tools (there are Raster or Vector tools depending on your data). In order to convert from Everest 1830, you will need to use the Define projection tool first, and set your data to use the predefined Geographic Coordinate System -> Sphere Based -> "Everest (definition 1937)". This is the mathematical equivalent of Everest 1830.
