The procedure is time consuming and causes non-homogenous accuracy of the horizontal and vertical position of control points. The proposed alternative approach is based on polar measurements using a high accuracy total station instrument and a special platform with two precise surveying prisms fixed on it. Measurements are carried out from a single station thus ensuring a common coordinate system and homogenous accuracy. The position of the characteristic point of a rail is derived from the measured positions of both prisms with known geometry of the platform. The influence of platform non-horizontality is defined, along with its elimination procedure. Accuracy assessment is ensured with redundant measurements. Result of the proposed procedure is a numerical and graphical presentation of characteristic points. The control parameters required in international Eurocode standards are easily determined from them.<\/jats:p>","DOI":"10.3390\/s120505906","type":"journal-article","created":{"date-parts":[[2012,5,8]],"date-time":"2012-05-08T11:13:15Z","timestamp":1336475595000},"page":"5906-5918","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["An Alternative Approach to Control Measurements of Crane Rails"],"prefix":"10.3390","volume":"12","author":[{"given":"Ale\u0161","family":"Marjeti\u010d","sequence":"first","affiliation":[{"name":"Faculty of Civil and Geodetic Engineering, University of Ljubljana, Jamova 2, 1000 Ljubljana, Slovenia"}]},{"given":"Klemen","family":"Kregar","sequence":"additional","affiliation":[{"name":"Faculty of Civil and Geodetic Engineering, University of Ljubljana, Jamova 2, 1000 Ljubljana, Slovenia"}]},{"given":"Toma\u017e","family":"Ambro\u017ei\u010d","sequence":"additional","affiliation":[{"name":"Faculty of Civil and Geodetic Engineering, University of Ljubljana, Jamova 2, 1000 Ljubljana, Slovenia"}]},{"given":"Du\u0161an","family":"Kogoj","sequence":"additional","affiliation":[{"name":"Faculty of Civil and Geodetic Engineering, University of Ljubljana, Jamova 2, 1000 Ljubljana, Slovenia"}]}],"member":"1968","published-online":{"date-parts":[[2012,5,8]]},"reference":[{"unstructured":"European Standard EN 1993\u20136: 2004.
