Remote sensing techniques make high-resolution terrain mapping easier and quicker. By Jose Diego Monroy, CFM, and Shuhab Khan, Ph.D. Terrain mapping measures the shapes and features of the terrain, which is important in fields such as land development, flood control and mitigation, landslide hazard identification and monitoring, project management, and obstruction identification The basic principle behind all photogrammetric measurements is the geometrical-mathematical reconstruction of the paths of rays from the object to the sensor at the moment of exposure. The most fundamental element therefore is the knowledge of the geometric characteristics of a single photograph. View chapter Purchase boo BASIC CONCEPTS OF PHOTOGRAMMETRY. 1. NAMITHA M. R. ID.

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 Photogrammetry is the technique that allows measurement of two points on the land or any other surface using a 2D photograph resulting in a survey map that gives a detailed idea about the spatial distribution of objects on the surface. The conversion of the mapped image can be done using the scale of the photogrammetric image

No matter which photogrammetry software program you choose, they all work on the same basic principles. Getting Started with Photogrammetry. First, it is important to have a high-quality camera when taking pictures of an object for photogrammetry. The quality of the resulting 3D model is dependent on the resolution of the photographs Fundamental Principle Triangulation is the fundamental principle used by photogrammetry. In this technique, we take photographs from atleast two different locations. The purpose of taking pictures from more than 2 points is to create what engineers call lines of sight. Once these lines of sight are prepared, we join them to locate a point.

The geometry of an aerial photograph is based on the simple, fundamental condition of collinearity.By definition, three or more points that lie on the same line are said to be collinear.In photogrammetry, a single ray of light is the straight line; three fundamental points must always fall on this straight line: the imaged point on the ground, the focal.

The basic principle of photogrammetry is to collect information from photographs taken at different angles of the same object and its environment. Then, the software uses the information and properly aligns the photographs to calculate the location of relevant points and the distances between those points in a 3D space Basic Photogrammetry. by GIS Resources , 2013-09-01.

The basic principle of photogrammetry mimics the natural ability of human depth perception. The ability of three dimensional vision is a result of the offset in perspective centers between the left and right eyes. Digital images created to simulate this perspective shift are referred to as stereoscopic. surveyors must be able to use the basic principles of photogrammetry necessary for flight and ground control planning to ensure that photogrammetric projects will meet National Map Accuracy Standards or other project-specific standards.
