Photogrammetry has evolved into a reliable substitution of ground surveying activities when large area mapping is necessary. It can relieve survey crews of the most tedious, time consuming tasks required to produce topographic maps and Digital Terrain Models (DTMs). Ground surve 2. INTRODUCTION TO PHOTOGRAMMETRY AND AIR SURVEY BY ASSISTANT PROFESSOR NASRUL HAQ. 3. DEFINITION • Photogrammetry is defined as the science of obtaining reliable measurements, by the use of photographs, in order to determine characteristics such as size, shape and position of photographed objects. 4 While pursuing his academics, he worked extensively on modern surveying techniques, like GPS, Photogrammetry, and LiDAR for topographic mapping. For research and teaching of modern surveying techniques for mapping at IIT Guwahati, he has been conducting various field related activities that require modern surveying technologies DOCUMENTATION, SURVEYING, PHOTOGRAMMETRY Boehler, W.

NPTEL provides E-learning through online Web and Video courses various streams 4. INTRODUCTION Photogrammetric surveying or photogrammetry is the branch of surveying in which maps are prepared from photo-graphs taken from ground or air stations. With an advancement of the photogrammetric techniques, photographs are also being used for the interpretation of geology, classification of soils and crops,etc Photogrammetry for Engineering Defined: Photogrammetry is the process of measuring images on a photograph. Modern photogrammetry also uses radar imaging, radiant electromagnetic energy detection and x-ray imaging - called remote sensing. 10. Aerial camera 11. Types of Aerial Photographs 12. Principle of Aerial survey 13 The photogrammetry is one of the most recommended methods of survey, since it is a non-intrusive method (English Heritage, 2006). Documenting of historic buildings is the first step for any intervention and planning (Mezzino et al, 2017). Before starting of the survey, it is necessary to analyse the existing documentation • Photogrammetry is a cost efficient surveying method for mapping large areas. • Photogrammetry may be safer than other surveying methods. It is safer to take photographs of a dangerous area than to place surveyors in harms way. • Photogrammetry provides the ability to map areas inaccessible to field crews

Photogrammetric Surveying Scale of a Vertical Photograph. H = height of exposure station (or the airplane) above the mean sea level. h = Height of ground above MSL. f = Focal length of the camera. If A and B are two points on the ground having elevations h a and h b above MSL, then the Average scale of a line joining A and B is given by. Datum. For example, a typical aerial survey might consist of photos at 1:4,800 scale. The desired output resolution for the orthophotos is approx. 30 cm. For 22.86 cm airphoto, a reasonable scanning resolution would be: r s = S * _____ * 2.54 2.54 p = 4800 _____ 30 = 406 DP CORS RTN is being used successfully to survey photogrammetric control. Other survey methods may still be acceptable, but RTK has been found to be the most efficient method. Consult with the Regional Land Surveyor for approval to use other survey methods. 10.4.1 Horizontal GPS Techniques Equipment 2/4/2009 10-9 Applications of photogrammetry Topographical mapping: • The plotting of map detail and contours is normally carried out using aerial photogrammetric methods • These methods are used for both original survey and revision, and replace classical ground methods except where the task is so small that flying is uneconomical • The technique.

main areas in photogrammetry where GPS can be used (Ackermann, 1994): 1- Establishment of ground control points using terrestrial GPS, 2- GPS controlled survey flight navigation, 3- High precision camera positioning for aerial triangulation, 4- Positioning of other airborne sensors (e.g., laser scanners) In the highway field, however, photogrammetry and aerial surveys have been largely confined to supplying a set of aerial photographs and to compiling maps photogrammetri-cally, usually large scale topographic maps for preliminary survey purposes. This limited use of methods has been caused by lack of mutual professional and technica surveying. Beaslef has also highlighted the unique- ness of photogrammetry and the savings in time and money in his survey of Honeymoon Island in United States. The difficulty of this survey resulted from the fact that the perimeter constantly changes due to tidal levels. A recent photogrammetric application in cadastra PHOTOGRAMMETRIC SURVEY. Photogram metric surveying or photogrammetry is the science and art of obtaining accurate measurements by use of photographs, for various purposes such as the construction of planimetric and topographic maps, classification of soils, interpretation of geology in land surveying maps and plan showing the features on the land. Types of Surveying On the basis of whether the curvature of the earth is taken into account or not, surveying can be divided into two main categories: Plane surveying: is the type of surveying where the mean surface of the earth is considered as a plane

Topographic surveying : It is carried out to the features such as hills, rivers, forests and man made features like villages, buildings, transmission lines and roads. Hydrographic surveying : Related with water bodies like low water level, high flood level etc. Gravity surveying : Fluctuation of gravity value from place to place. Based on instruments:. 3. Space Photogrammetry: The space photogrammetry embraces all aspects of extraterrestrial photography and subsequent measurement wherein the camera may be fixed on earth, contained in an artificial satellite, or positioned on the moon or a planet.

In addition to world-building, photogrammetry can also assist with designing special effects and real sets. 7. Forensics. Photogrammetry also plays a part in crime investigation

This is a significant advantage over photogrammetry, as photogrammetric surveying will only produce high vertical accuracy when there is sparse vegetation on site. While lidar does have similar limitations, it can penetrate areas with up to 90% vegetation under good conditions. (Photogrammetry sits closer to the 60% mark. Photogrammetry, as its name implies, is a 3-dimensional coordinate measuring technique that uses photographs as the fundamental medium for metrology (or measurement). The fundamental principle used by Photogrammetry is triangulation or more specifically called Aerial Triangulation. By taking photographs from at least two different locations, so. In photogrammetry, one of the critical parameters required to process the data accurately is image overlap that should be at the level of 60-90% (front and side) depending on the terrain structure and hardware applied. The typical LiDAR survey requires only 20-30% overlap between flight lines, which makes the data acquisition operations much. Abstract. Photogrammetry has influenced survey practice drastically since its introduction as a mapping tool. Aerial photographs specifically for mapping purposes were first taken in 1913, although ground photography had been used to a limited extent in field surveys as early as 1894. 1 The first major mapping project in the United States was conducted by the U.S. Geological Survey and the.

Below is a list of a few of the advantages that Photogrammetry offers as compared to traditional methods:. The foremost advantage of photogrammetry is the ease and speedat which the data can be collected.With the use of UAV, UAS, or satellite imagery, photogrammetry can help in capturing images, analyze the data to get the measurements and convert them to a 3D map in no time and least cost Drone software for optimal aerial monitoring and surveying. Reduce field time and overall surveying time. Pix4D photogrammetry software allows the mapping of medium to large areas faster, saving a lot of time and accepting more contracts with the same internal resources. Integrate photogrammetry surveying into your current workflow Photogrammetry is the process of generating a 3D model from a set of 2D photographs. In surveying, this is done by taking two or more images of the same point from different angles. These images are then loaded into a photogrammetry software suite like PhotoModeler, which displaces the images by a baseline, and uses this data to triangulate the. October 25, 202 Photogrammetry is the science of making measurements from photographs. The output from photogrammetry is typically a map, a drawing or a 3D model of some real world object or land mass. 3D Maps And Models To create 3D maps from aerial photogrammetry, the camera is mounted on the drone and is usually pointed vertically towards the ground
