The first step to be run as part of the compensation is to determine preliminary coordinates. They are determined with a precision low accuracy generally depends on the purpose and length of the sides of the network considered. Because the projection system used officially in Romania is 1970 stereographic system for processing observations is usually a two-dimensional system still will consider that this plan is the reference surface which will reduce geodetic observations. If the geodesic network of the distance measurements were made, to be reduced from the reference surface selected. After being corrected physical (generally modern tools to measure distances apply this correction automatically) distances measured to be applied, in order, the following discounts: Reducing the chord; Reduction of the reference ellipsoid surface; Reduction plan stereographic projection in 1970.This stage of preliminary processing geodetic observations and reduction in the chosen reference surface is considered performed by the user, for which the program will be introduced reduced to the reference surface observations.
