    Geodesy (/ dʒ iː ˈ ɒ d ɪ s i /) is the Earth science of accurately measuring and understanding Earth's geometric shape, orientation in space and gravitational field. The field also incorporates studies of how these properties change over time and equivalent measurements for other planets (known as planetary geodesy). Geodynamical phenomena include crustal motion, tides and polar motion. Common task Where to go for more information; To define the spatial reference for a new dataset in the geodatabase. See An overview of spatial references in the geodatabase. To record the coordinate system of an existing dataset. See the "Define Projection" tool in An overview of the Projections and Transformations toolset.

      Learn what a map projection is, why they are used and what impact they have on maps GIS systems. We will taker a closer look at the popular Mercator projection and examine how the projection. Different datums are used different places because some fit some areas better than others. A projection is a formula used to convert long/lat coordinates into a flat coordinate system that you can use on paper or a computer screen. It's usually done from a geographic coordinate system, which in turn uses a datum as it's base definition.

      Psychological projection is a defense mechanism people subconsciously employ in order to cope with difficult feelings or emotions. Psychological projection . The main themes include: the various techniques of geodetic data acquisition, geodetic datum and geodetic control networks, geoid and height systems, reference ellipsoid and geodetic coordinate systems, Gaussian projection and Gaussian plan coordinates and the establishment of geodetic coordinate systems.

The theory of geodetic projections has much in common with the theory of cartographic projections, but in a cartographic projection a minimum of distortion is required above all, whereas geodetic projections require that such distortions be strictly and simply taken into consideration.

Use of the points of a geodetic grid as base points in surveying a locality makes it necessary to fit. Coordinate systems enable geographic datasets to use common locations for integration.

A coordinate system is a reference system used to represent the locations of geographic features, imagery, and observations such as GPS locations within a common geographic framework. Each coordinate system is. common use for the description of the physical world. Certainly the most common is the Cartesian or rectangular coordinate system (xyz).

Probably the second most common and of paramount importance for astronomy is the system of spherical or polar coordinates (r,θ,φ). Less common but still very important are the cylindrical coordinates (r,ϑ,z). Map projections: theory and applications.

All measurements are relative to some reference, and our best estimates of the reference have changed (better measurements, better models).

We started with, visualize the World, and still use 2‐ dimensional systems of coordinates. Well, it is not, so we have a choice. We can use geodetic computations when laying out or observing a station, or we can use a map projection and pretend the Earth is flat.

The latter will provide the same results as geodetic computations but requires that all observations are on the map projection surface. Geodetic leveling has always played second fiddle to horizontal surveys. Perhaps this is so because leveling is perceived as a simple procedure, although it most certainly is not.

Some form of leveling, mostly trigonometric in nature was always observed in order to provide elevations needed to reduce base lines and angle observations to sea level. In geodesy, conversion among different geographic coordinate systems is made necessary by the different geographic coordinate systems in use across the world and over time.

Coordinate conversion is composed of a number of different types of conversion: format change of geographic coordinates, conversion of coordinate systems, or transformation to different geodetic datums.

Projection is a rigid and sometimes fragile defense, so tread carefully. When we use projection, it makes it hard for us to properly interpret others' intentions, often leading to mistrust and.

It differs from the plane survey mentioned earlier in that more accurate instruments are used, instrumental errors are either removed or predetermined so that they can be compensated for in the computations and more rigorous procedures are employed to reduce observational errors.
