Set Datum Transform Version statement - MapBasic - 2023

Purpose

This statement allows user to switch between using old and new datum conversion. You can issue this statement from the MapBasic window in MapInfo Pro.

Syntax

Set Datum Transform Version version_number

version_number is an integer value. If version_number is equal or more than 800, than updated datum transformation algorithms are used. Otherwise old algorithm is used.

Description

By default, MapInfo Pro uses updated datum conversion algorithms. These algorithms are more in line with algorithms used by other software packages and it is recommended not to changed version from default. In previous versions of MapInfo Pro we used optimized for speed algorithms and our results were slightly different from other software packages/tools.
