what is the fundamental difference between plane surveying and geodetic surveying?

Plane surveying is the process of surveying by assuming that the earth is flat. Which mean the curvature or spherical shape of the earth is not considered in plane surveying calculations. Geodetic surveying is a process of surveying by considering the curvature or spherical shape of the earth.

And here's the answer... 'Direct measurement' refers to measuring exactly the thing that you're looking to measure, while 'indirect measurement' means that you're measuring something by measuring something else.

A plane figure is two-dimensional, and a solid figure is three-dimensional. The difference between plane and solid figures is in their dimensions. ... The same shape takes on extra dimension by adding additional points and lines to give the shape height, width and depth.

In brief, aeronautical deals with flight in the earth's atmosphere, astronautical deals with travel in space, and aerospace covers both realms. To understand more about aerospace engineers, see our related article on how to become an aerospace engineer.

Geographers can describe the location of a place in one of two ways: absolute and relative. Both are descriptives of where a geographic location is. Let's learn about the difference between absolute and relative location.

Land Surveyor Degree Programs Due to the increasingly technical nature of the profession, most employers require you to hold a bachelor's degree in surveying, mapping or geomatics. Such degree programs usually include courses such as calculus, geographic information systems (GIS) and cartography.

A geographic information system (GIS) is a computer-based tool for mapping and analyzing features and events on earth. ... On the other hand, remote sensing is the science of collecting data regarding an object or a phenomenon without any physical contact with the object.

So what is the difference? The fundamental difference is that Model Lines show up in every view, and Detail Lines show up only in views perpendicular to the plane they were drawn. So if you want to draw some linework to show up in an elevation view, but don't want to see it in plan or in 3D, then use drafting lines.

Geodesy, the science of measuring the Earth's shape and positions on it, allows the measurement of plate motion directly using GPS, the Global Positioning System. This network of satellites is more stable than the Earth's surface, so when a whole continent moves somewhere at a few centimeters per year, GPS can tell.

Azimuth and Elevation are measures used to identify the position of a satellite flying overhead. Azimuth tells you what direction to face and Elevation tells you how high up in the sky to look. Both are measured in degrees. Azimuth varies from 0° to 360°. It starts with North at 0°.

There is a significant difference between a questionnaire and a survey. A survey is defined as the evaluation of experiences or opinions of a group of people via questions as opposed to a questionnaire which is defined as a collection of written or printed questions with an answer choice made to conduct a survey.

Oblique aerial photograph is taken with the axis of the camera held at an angle between the horizontal plane of the ground and the vertical plane perpendicular to the ground. A low oblique image shows only the surface of the earth; a high oblique image includes the horizon.

Land surveying, is marking the points depending on drawing. Marking the boundaries of site finding it's area and other geometric properties. Staking out curves or other required shapes. Quantity surveying, is estimation of quantities required for construction.

Plane stress is an approximate solution, in contrast to plane strain, which is exact. In other words, plane strain is a special solution of the complete three-dimensional equations of elasticity, whereas plane stress is only approached in the limit as the thickness of the loaded body tends to zero.

Indicated altitude is pressure altitude corrected for local atmospheric conditions. ... All aircraft in a given area should be on the same altimeter setting so relative (altitude) separation is maintained. A GPS, on the other hand, measures your absolute altitude off several satellites.
