One map policy has been set by the Indonesian government in accelerating development. One map policy is closely related to the SRGI 2013 datum reference and its definition in horizontal control point. Mapping in Indonesia still often uses references on the WGS ’84 datum. Therefore, it is necessary to evaluate the difference of coordinates of the horizontal control points on SRGI 2013 and WGS ’84. This study uses horizontal control network around UGM area which has 6 points. Data measurement and processing is carried out in accordance with SNI of Horizontal Control Network. Evaluation is done by statistical test on the difference of coordinates. The results of this study indicate that the horizontal control network has the highest coordinate accuracy on the vertical component in centimeter fraction. In addition, based on the results of statistical test, the difference of coordinates have significant values on all points and all components both X, Y and Z components.
