Preparing the map for design purposes with the use of the photogrammetry method

Upon the commission of PKP Polskie Linie Kolejowe S.A., we have prepared a map for design purposes with the use of the photogrammetry method for the project TEN-T 2004-PL-92601-S “Modernisation of the railway line E 30 in the section Kraków – Medyka – State Border”.

We have assumed a uniform and stable geodetic control network and prepared geodetic materials for the modernisation of the railway line E 30 in the sections Kraków – Tarnów and Rzeszów – Medyka – State Border.

The geodetic control network in the form of GPS points with the accuracy of class I and II of basic geodetic control network and sequences of network points constitutes the reference system for the purpose of preparing, conducting and stock-taking of the investment and its future use.

While preparing geodetic materials, we have created an orthophotomap in the scale 1:500 and the Digital Terrain Model (DTM). We have also drafted a 3D planimetric and contour map with underground area infrastructure and land register for the design purposes in the scale 1:500 on the basis of the orthophotomap and direct supplementary measurements. We have executed a profile of a railway line. These materials are necessary for the construction design, execution and stock-taking of the investment and later use of the modernised railway line.
