- The combined scale factor in surveying can be found by multiplying the grid scale factor and the elevation factor. These two scale factors correct the combined linear distortions caused by the curvature of the earth and the ground height of the measured distances above the ellipsoid surface with respect to the projection surface.

Once the elevation factor is available, it is multiplied with the scale factor. The result is known as the combined factor. The combined factor will move the line from the topographic surface of the Earth to the state plane (aka grid).

Combined scale factor. The applied distance factor value is calculated as a combined scale factor using grid scale and elevation factors. The combined scale factor is the product of multiplying the grid scale factor and the elevation factor.
Apr 22, 2015 · Multiplying the elevation factor and the scale factor produces a single ratio that is usually known as the combined factor or the grid factor. Using this grid factor the measured line is converted from a ground distance to a grid distance in one jump.
The combined scale factor is used when calculating the surface distance between two points on a map by the equation: The scale factor component compensates for the curvature of Earth’s surface and
6 days ago · The combined scale factor is calculated using the formula: \ [ CSF = GSF \times EF \] where: \ (CSF\) is the Combined Scale Factor, \ (GSF\) is the grid scale factor, \ (EF\) is the elevation factor.
Feb 14, 2017 · Similarly, the scale factor for 501 was determined to be 0.99992586. The average of these scale factors is 0.99992585. The combined factor is then determined as 0.99995682(0.99992585), which yields 0.999882675.
May 26, 2022 · The combined scale factor (CSF) is usually used to convert a ground distance to grid distance which is the product of elevation scale factor (ESF) and grid scale factor (GSF). Figure 1. Combined scale factor (CSF) can be greater or less than 1.0 depending on the relationship between ground distance and grid distance as illustrated in Figure 1.
