Topographic mapping of roads in the Sustainable Urban Development area

This report describes the methods and techniques applied to prepare the study entitled “TOPOGRAPHIC MAPPING OF ROADS OF THE SUSTAINABLE URBAN DEVELOPMENT AREA“. The object of the study was the detailed topographic survey of selected roads in built-up areas. Specifically, this study includes the mapping of common areas between building blocks that are in contact with the facades of buildings or front gardens (if they exist) along the selected roads, with all the elements included in them. The study area is located within the Municipal Community of Chania, of the Municipal Unit of Chania, of the Municipality of Chania, of the Prefecture of Crete. Specifically, it includes parts of the following streets: Eleftheriou Venizelou, up to the Iroon Polytechniou Street, Hatzimichali Giannari., Str. Tzanakaki, Charilaou Trikoupi, Skalidi, Andreas Papandreou, Apokoronou, between Grigoriou the 5th and Solomos, Sfakion, Erotokritou, Voloudaki and Valaoritou, between Tzanakaki and Skalidi streets.

About the procedure

All the surveying work was carried out in between September 5 – September 13, 2017. The preparation of the topographic works was carried out in accordance with the technical specifications defined by the applicable legislative provisions (Presidential Decree 696/1974). The reference system of the survey is the Hellenic Geodetic Reference System of 1987 (EGSA ’87) and the geodetic display (projection system), in which the performance of the measurements was performed, is the Transverse Mercatoric display of a zone or ΤΜ87.

In the context of the preparation of the present study, a Trigonometric Network was established and a detailed topographic survey was carried out, on a scale of 1:200, in the area defined by the above-mentioned sections of the streets located in the Sustainable Urban Development area, in the city of Chania.

In detail, the topographic works carried out include the following stages:

  1. Trigonometric Network Installation,
