Sažetak
The tunnel "Mala Kapela" is the longest tunnel in the Republic of Croatia. This paper present and analyses the geodetic basis of the tunnel "Mala Kapela". The underground geodetic basis consists of: - two networks in the right tunnel tube made in the form of a triangle chain (one in the northern, and the other in the southern part of the tunnel) - two traverses in the left tunnel tube (one in the northern, and the other in the southern part of the tunnel) - two precise closed traverses (one in the northern, the other in the southern part of the tunnel). The error sources in direction measurements have been processed with special consideration of the initial bearing angle error. There are the formulas presented for corrections and reduction of lengths measured with electro optical distance meter. The tunnel geodetic basis in the form of a triangle chain is presented that meets the set criteria in the best way referring to the tunnel cutting accuracy. At the end, there is the positional uncertainty of points presented that the tunnel "Mala Kapela" was cut from.
