EXAM - Essay Example Space geodesy is also known as satellite geodesy. Point positioning is a major application that accurately determines the coordinates of points in space, land and sea. The locations of points are determined by linking measurements of known points with terrestrial positions that are not known.It may include transformation between astronomical C.S and terrestrial C.S. Use of GPS satellites, triangulation and other satellite geodesy are used to for the known points positioning. The satellite geodesy is relevant in intersatellite tracking. Space geodesy determines the positions of points, both relatively and absolutely. Space geodesy, currently, has been formed to provide abundant and accurate geodetic data than the classical systems. Satellite geodesy helps in determination of precise local or regional geodetic control, earth’s gravitational pull determination and modelling and measurement of geodynamic phenomenon. Geodynamic phenomenon include polar motion,crustal deformation and the earth’s rotation. Space geodesy consists observation and computational techniques which allow for solutions above geodetic problems by precise measurements to or from artificial satellites. This is the geodesy aspect that strictly concerns geometrical relationships of the earth’s surface. The earth’s surface is measured in different ways, such as triangulation, electronic surveys and trilateration for the purpose of determining the shape, size of the earth and the precise location of points on the surface of the earth. Geometric geodesy is a science that considers the geoid by the use of astrogeodetic method. Most of the spatial data errors are processing errors: Numerical errors, cascading errors, topological errors, digitizing and geocoding errors. Processing errors are those errors that are introduced during digitizing and processing. For example, conversion of data from raster to

Value of Art to the People Essay Example | Topics and Well Written Essays - 1000 words

Value of Art to the People - Essay Example To this end, the piece of art serves them a memory of what they normally refer to as the sacrifice of Christ and so as it would naturally be expected, the value the sacrifice and thus the art dearly. The notion I develop about the people is that they are highly religious with so much emphasis on the Christian religion. From the piece of art I saw and how carefully the people have invested into the beauty and glamour of the art, it will not be out of place to say that most of the people are Christians who cherish the sacrifice of their religious leader highly. Again, I get the notion that even though there may as many popular cultures associated with the people, they are more inclined to their religious concepts than other aspects of their lives. There were two major components of the piece of art that was seen. The first has to do with the scene of an oval vessel with a sealed base. The vessel is made of clay and so could be said to be a ceramic art. The vessel can, therefore, hold w ater and food. The second scene is a tripod that has been made of stone. The color of the vessel and the stones are the same but there has been any color used to create other designs on the vessel. Looking closely at the piece of art, one can tell how the people value the availability of food and water, which are two of the major needs for human existence. However, the piece of art preaches that food and water can be made available only when the people come together as a collective force; as in the case of the tripod to work together. Indeed, the vessel cannot stand if any of the three stones is removed. From the value of the art to the people, I get a notion that the people are highly hard working and believe in the virtue of unity. It is not surprising there is the saying among the Chinese, who are also Asians that in unity is strength.
