Types of Photogrammetry. In the practice of photogrammetry there are two main methods for collecting photographs. Pictures can be taken on traditional tripods set on the ground; this is known as terrestrial photogrammetry. By taking multiple overlapping photos, objects can be measured stereoscopically in three-dimensions 1. Terrestial or Ground Photogrammetry: In terrestrial photo-grammetry maps are prepared from terrestrial (or ground) photographs or terrestrial photogrammetry employees photograph taken form points on earth surface for measurement purposes. The terrestrial photographic surveying considered as the further development of plane table surveying Terrestrial photogrammetry, also known as close-range photogrammetry, uses a tripod-mounted or handled photogrammetry camera located on the ground. This type of photogrammetry is usually non-topographic, meaning it's used to create drawings, 3D models, measurements and point clouds rather than topographic products like terrain models or maps Depending on the properties of an object which has to be modeled, different types of photogrammetry are used. Primary classification is made on the basis whether the photo-graphs are taken from the air or from the ground. If satellite or airplane images show ter-rain, photogrammetry is aerial [1, 10]. Terrestrial photogrammetry use images made from a spot close to the ground, and generally do not represent terrain, but smaller natural or artificial objects
Aerial and terrestrial are two major types of photogrammetry photogrammetry are less accurate than ground surveys (when compared to conventional or GPS ground survey methods using appropriate elevation procedures). 3. Identification of planimetric features can be difficult or impossible (e.g. type of curb and gutter, size of culverts, type of fences, and information on signs). 4 The principal is exactly similar to plan table surveying, it may be stated as The position of the object with ref to the base line is given by the intersection of the rays drawn to it form each end of the base line In plane tabling most of the work is executed in the field while in this method it is done in the office. The principal is explained as follows: C and D = Camer . (ii) Terrestrial stereo photogrammetry . The plane table photogrammetry consists essentially in taking a photograph of the area to be mapped from each of the two or three stations Terrestrial photogrammetry was the standard method for mapping high mountain terrain in the early days of mountain cartography, until it was replaced by aerial photogrammetry (cp. Kostka, 2004 and Brunner, 2006). Although terrestrial photogrammetry has many drawbacks compared to aerial photogrammetry, e.g., area-wide mapping cannot b
Photogrammetry software is also often more accessible and affordable, as it can be as simple as inputting a photo from your smartphone's camera into the software and then having a 3D reconstruction automatically generated. Types of Photogrammetry. There are two main types of photogrammetry - aerial and terrestrial photogrammetry In Terrestrial and Close-range Photogrammetry, the camera is located on the ground, and hand held, tripod or pole mounted. Usually this type of photogrammetry is non-topographic - that is, the output is not topographic products like terrain models or topographic maps, but instead drawings, 3D models, measurements, or point clouds

There are two types of images or photos capture using terrestrial photogrammetry technique, such as static and dynamic. Static photo refers to photo of stationary object such as the topography image of the earth surface while dynamic photo refers to photo of moving object 2 Terrestrial and Close-Range Photogrammetry. • Aerial Photogrammetry: In this kind of photogrammetry the camera is mounted on an aircraft which can take many photographs of the area from different edges restrial photogrammetry during the last few years has concentrated mainly on close-range photogrammetry. In spite of the elaborate work of Zellers, terrestrial photogrammetry has been used relatively little in photogram- metric practices. Although Zeller's approach was a cartographic type of photogrammetry The principle of terrestrial photogrammetry was improved upon and perfected by Capt. Deville, then Surveyor General of Canada in 1888. In terrestrial photogrammetry, photographs are taken with the camera supported on the ground. The photographs are taken by means of a photo theodolite which is a combination of a camera and a theodolite..
Types of photographs • Two basic classification of photography 1-Terrestrial photogrammetry is an important type of the science of photogrammetry. It deals with photographs taken with cameras located on the surface of the earth. The cameras may be handheld, mounted on tripods, or suspended from towers or other specially designed mounts. Types of photographs used in photogrammetry (A) Terrestrials photograph . The photographs taken from a camera station from at fixed point on or near the ground is called a terrestrial photograph. (B) Aerial photographs . The photographs are taken from a camera station in the air with the axis of the camera is vertical or nearly vertical. Terrestrial photogrammetry comparatively needs much less investment and technical skill to carry out. b) The aerial kind of photogrammetry is suitable when we are trying to map a large piece of land. Terrestrial photogrammetry is a preferred method when designers and planners aim to monitor and map bridges, pipeline networks, transport network.
c. Instrumentation (1) Cameras. Cameras for engineering applications of terrestrial photogrammetry should be stable, calibrated metric cameras similar to aerial cameras. For highest accuracy, some cameras expose the image directly on glass planes to ensure image plane flatness. Film type cameras should have a film-flattening device The Basics of Photogrammetry.

(B) Histogram of point-to-point distances. (C) Example offset on east-facing outcrop
Where remote sensing differs from photogrammetry is in the type of information collected, which tends to be based on differences in color, so land use and land cover is one of the primary output of remote sensing processing. Remote sensing was originally conceptualized to exploit the large number of color bands in satellite imagery to create 2D. Consider what it costs in terms of hardware, software and manpower time to gear up and accomplish a 10-acre building campus survey using a terrestrial laser scanner process compared to drone/photogrammetry process. Adding reliable automatic point cloud classification, photogrammetry-based surveying for construction just took another big leap ahead In geodetic applications, terrestrial (global) and reference (regional) coordinate systems, as well as local coordinate systems, are used. Reference coordinate systems include national geodetic coordinate systems. The Global coordinate system is a geocentric spatial coordinate system with a beginning at the mass center of the Earth AutoCAD. By using digital terrestrial photogrammetry the existing architectural features can be modelled, whereas other data sources are required to model the size, shape and location of missing features. This investigation involved creating a CAD model of the Hunter Memorial, Glasgow University, using digital photogrammetry, the reconstruction o Photogrammetry can be described as a passive technique to derive reliable and precise measurements by means of photographs/images or as the art of turning images into 3D models . To build a 3D model using photogrammetry, many types of images can be used like satellite, airborne, balloon, UAVs, terrestrial and even underwater images
