Abstract
There are several techniques to obtain new map projections by combining two known projections. The aim of these techniques is to achieve a defined distribution of distortion, type of distortion, or certain forms of graticules. The obtained projection may or may not retain the properties of the two initial projections. In this study, a technique was developed to combine two conformal projections, namely the conical and Gauss-Kruger projections. This technique retained the properties of the two initial projections, i.e., it preserved conformality. Furthermore, the developed technique could be described as flexible because it contained two different weighted parameters, which defined as the percentage of each projection in the combination process. It was observed that the value of the weight differed from case to case depending on the geographic location, shape, and extension of the mapped area.
