Which statement is NOT true regarding geographic to grid conversion?

In the context of geographic to grid conversion, understanding the role of the coefficient p is crucial. The coefficient p is a critical component in determining how a point's geographic coordinates translate into grid coordinates, particularly in a projected coordinate system.

When analyzing the statements, it is true that the coefficient p is positive if the point is located to the east of the Central Meridian. This means that as you move east, the coefficient p increases positively, which is necessary for accurate positioning in the grid system.

Furthermore, the sign of p does indeed not affect the computed Northing of a point. Northing refers to the factor of the coordinate system that determines how far north a point is. The Northing value is calculated in a way that is essentially independent of the east-west positioning represented by p.

The assertion that the coefficient p is positive if the point is on the west of the Central Meridian is inaccurate. In fact, when a point is located to the west of the Central Meridian, the value of p would be negative. This influences how geographic coordinates are transformed into grid coordinates, needing careful consideration to avoid errors in mapping and data representation.

Thus, the statement that is NOT true regarding geographic to grid conversion is that the coefficient p is positive for points located west
