In order to carry out the topographic surveys in order to carry out the situation plans, measurements were made in the field with the GPS equipment North Smartk. Topographic operations performed in the field: Route length (Plan No. 2, A size, scale 1: 5000) 5.6 km the details that need to be measured and the route to be traveled have been identified in the field, 2 support points were determined, S100, S200. The points were determined using the GNSS North Smartk receiver, by the RTK method using corrections from the ROMPOS system, with the reference station: Ro_VRS_3.1_GG. To verify the coordinates, 3 determinations were made for each point at 30 minutes intervals, each time with a new reset of the receiver. As a result of the checks, there were no errors in determining the points. The points were materialized in the field with wooden chisels. The final coordinates of the points are: 100 : X=442807.373, Y=357094.574, Z=483.728m and 200 : X=442832.326, Y=442832.326, Z=483.728m. The points were also checked with Trimble 5603, DR 200+ total station.A total of 5021 points were measured. The accessible points were determined with the telescopic milestone with the prism having the height of 2.00 m, the inaccessible points being determined with the Direct Reflex technology directly on the surface of the measured object. The points determined with this technology have an exact positioning only planimetric (X and Y), not level. Preparation of the situation plan: The data downloaded from the total station were processed to prepare the situation plan (Sheet No.1, format A0 scale 1: 2000). Route length (Plan No. 2, A size, scale 1: 5000) 5.6. For the realization of the situation plans, the AutoCad program was used together with the TopoLT program for importing points and ProofLT for profiling. Post-processing of RiNNEX data was a mandatory condition for verifying the obtained coordinates.
