APPLICATION OF TERRESTRIAL PHOTOGRAMMETRY FOR GLACIER MONITORING IN ALPINE ENVIRONMENTS Sebastian Finsterwalder (1862-1951) Ölgruben rock glacier Measurement of flow/creep velocity by means of terrestrial photogrammetry, first survey: 1923, repeat survey: 1924, result: movement max. D. Fugazza et al. The principle underlying the method of terrestrial photogrammetry is exactly similar Using ten ground control points, Barry and Coakley  found that aerial drone photogrammetry survey was reliable within 41 mm horizontally and 68 mm vertically with a 1 cm ground sample distance. The map shows the location of take-off and landing sites for the 2014 and 2016 UAV surveys, standpoint of TLS survey, GCPs used in the UAV photogramme-try surveys and trails crossing the glaciers. 50 cm/year (>repeat survey by W. Pillewizer) PHOTOGRAMMETRY 1.0 Introduction Photogrammetry or aerial surveying is a method of surveying generally used to cover large area. In this paper terrestrial photogrammetry is analyzed and its applications in architecture presented. Several studies have been conducted assessing the accuracy of terrestrial photogrammetry survey using aerial drones and compared to RTK survey. The traditional way to survey the territory for landslide detection purposes is aerial or, in some cases, terrestrial photogrammetry, that permits to carry out 3D models of the terrain and, by means of DTMs comparisons, to realise multi-temporal studies. Any type of imagery –photographs, digital or CCD images, images using thermal or other scanning systems from a satellite etc. Terrestrial or ground photogrammetry. detect, classify and monitoring landslides. ii). Maps are then compiled from the photographs. There are two type of photographic surveying. The photographs are taken by means of a photo theodolite which is a combination of a camera and a theodolite. In terrestrial photogrammetry maps are prepared from ground photographs from different points on the earth surface for measurement purpose. TERRESTRIAL PHOTOGRAMMETRY AND APPLICATION TO MODELING ARCHITECTURAL OBJECTS UDC 528.711:72.01+721(045)=111 Vesna Stojaković Department of Architecture, Faculty of Technical Sciences, University of Novi Sad, Serbia Abstract. In terrestrial photogrammetry, photographs are taken with the camera supported on the ground. The tongue of Forni Glacier. may be used in this method. : Combination of UAV and terrestrial photogrammetry to assess rapid glacier evolution 1057 Figure 1. In aerial photogrammetry maps are produced from air from an airplane or helicopter. i). Aerial photogrammetry. It can relieve survey crews of the most tedious, time consuming tasks required to produce topographic maps and Digital Terrain Models (DTMs). Ground survey Photogrammetry has evolved into a reliable substitution of ground surveying activities when large area mapping is necessary.
