Abstract

The paper presents a concept of application of the RTK-GPS technique to surveys of railway tracks. The concept was examined during an experimental survey performed over a 2 km long track section. The test survey confirmed functionality and sufficient accuracy of the RTK-GPS method as applied to railway track measurements aimed at track regulation.

Abstract

The radar method, executed with the use of ground penetrating radars - the georadars, belongs to non-intrusive methods of positioning subsurface structures and objects. The direct result of the survey is the so-called radargram - a radar image, that is a vertical cross-section of the penetrated medium. It brings an information on the existence and mutual position of ground layers and subsurface structures and objects. The radargram, as the direct result of measurement, demands further processing for its interpretation and use. The consecutive steps leading from a non-metric radargram to the metric 3D model, based on corresponding surveying and georadar data are presented. The paper concentrates on the problem of broadening the scope of interpretation and applications of georadar surveys thanks to proper integration of advanced filtering programs, graphical software and programs from the CAD and SIT environment. The aim of the integration is a metric 3D model of subsurface objects and structures located with the georadar method. The ways and stages of generation of the spatial subsurface models, presented in the paper, complement surveying sources of data for thematic maps.
