[2] Is a Geographical Term for the Half of the Earth Th at Li Western Hemisphere The Western Hemisphere The Western Hemisphere[1][2] is a geographical term for the half of the earth th at lies west of the prime meridian (which crosses Greenwich, UK) and east of the antimeridian, the other half being called the Eastern Hemisphere.[3] In this sense, the Western Hemisphere consists of the Americas, the western port ions of Europe and Africa, the extreme eastern tip of Russia, numerous territori es in Oceania, and a portion of Antarctica, while excluding some of the Aleutian Islands to the southwest of the Alaskan mainland. In an effort to define the Western Hemisphere as the parts of the world which ar e not part of the Old World, there also exist projections which use the 20th mer idian west and the diametrically opposed 160th meridian east to define the hemis phere.[4][5] This projection excludes the European and African mainlands and a s mall portion of northeast Greenland, but includes more of eastern Russia and Oce ania. The population of the geographical Western Hemisphere exceeds 1 billion. Of the four hemispheres, only the Southern Hemisphere is less populated. The highest mountain in the Western Hemisphere is Aconcagua in the Andes of Arge ntina at 6,960.8 metres (22,837 ft).

    World Geodetic System 1984 Responsible Organization: National Geospatial-Intelligence Agency Abbreviated Frame Name: WGS 84 Associated TRS: WGS 84 Coverage of Frame: Global Type of Frame: 3-Dimensional Last Version: WGS 84 (G1674) Reference Epoch: 2005.0 Brief Description: WGS 84 is an Earth-centered, Earth-fixed terrestrial reference system and geodetic datum. WGS 84 is based on a consistent set of constants and model parameters that describe the Earth's size, shape, and gravity and geomagnetic fields. WGS 84 is the standard U.S. Department of Defense definition of a global reference system for geospatial information and is the reference system for the Global Positioning System (GPS). It is compatible with the International Terrestrial Reference System (ITRS). Definition of Frame • Origin: Earth’s center of mass being defined for the whole Earth including oceans and atmosphere • Axes: o Z-Axis = The direction of the IERS Reference Pole (IRP). This direction corresponds to the direction of the BIH Conventional Terrestrial Pole (CTP) (epoch 1984.0) with an uncertainty of 0.005″ o X-Axis = Intersection of the IERS Reference Meridian (IRM) and the plane passing through the origin and normal to the Z-axis. The IRM is coincident with the BIH Zero Meridian (epoch 1984.0) with an uncertainty of 0.005″ o Y-Axis = Completes a right-handed, Earth-Centered Earth-Fixed (ECEF) orthogonal coordinate system • Scale: Its scale is that of the local Earth frame, in the meaning of a relativistic theory of gravitation. Aligns with ITRS • Orientation: Given by the Bureau International de l’Heure (BIH) orientation of 1984.0 • Time Evolution: Its time evolution in orientation will create no residual global rotation with regards to the crust Coordinate System: Cartesian Coordinates (X, Y, Z).

Definition (Geographic Information System) A GIS is a computer-based system to aid in the collection, maintenance, storage, analysis, output and distribution of spatial data and information. In this course, we will focus mainly in collection, maintenance, analysis and output of spatial data. Main goals of the course: 1 Understand some basic principles of Geographic Information Science behind GIS; 2 Become familiar with the use of GIS tools (in particular QGIS); 3 Prepare yourself to undertake new analyses using GIS beyond this course.

  • Chandler and Annual Wobbles Based on Space-Geodetic Measurements
    ISSN 1610-0956 Joachim Hopfner¨ Chandler and annual wobbles based on space-geodetic measurements Joachim Hopfner¨ Polar motions with a half-Chandler period and less in their temporal variability Scientific Technical Report STR02/13 Publication: Scientific Technical Report No.: STR02/13 Author: J. Hopfner¨ 1 Chandler and annual wobbles based on space-geodetic measurements Joachim Hopfner¨ GeoForschungsZentrum Potsdam (GFZ), Division Kinematics and Dynamics of the Earth, Telegrafenberg, 14473 Potsdam, Germany, e-mail: [email protected] Abstract. In this study, we examine the major components of polar motion, focusing on quantifying their temporal variability. In particular, by using the combined Earth orientation series SPACE99 computed by the Jet Propulsion Labo- ratory (JPL) from 1976 to 2000 at daily intervals, the Chandler and annual wobbles are separated by recursive band-pass ¦¥§£ filtering of the ¢¡¤£ and components. Then, for the trigonometric, exponential, and elliptic forms of representation, the parameters including their uncertainties are computed at epochs using quarterly sampling. The characteristics and temporal evolution of the wobbles are presented, as well as a summary of estimates of different parameters for four epochs. Key words: Polar motion, Chandler wobble, annual wobble, representation (trigonometric, exponential, elliptic), para- meter, variability, uncertainty 1 Introduction Variations in the Earth’s rotation provide fundamental information about the geophysical processes that occur in all components of the Earth. Therefore, the study of the Earth’s rotation is of great importance for understanding the dynamic interactions between the solid Earth, atmosphere, oceans and other geophysical fluids. In the rotating, terrestrial body-fixed reference frame, the variations of Earth rotation are measured by changes in length-of-day (LOD), and polar motion (PM).

  • Benefits of Combined GPS/GLONASS Processing for High Sensitivity Receivers (URL
    UCGE Reports Number 20333 Department of Geomatics Engineering Benefits of Combined GPS/GLONASS Processing for High Sensitivity Receivers (URL: http://www.geomatics.ucalgary.ca/graduatetheses) by Mohamed Essam Hassan Roshdy Tamazin July 2011 UNIVERSITY OF CALGARY Benefits of Combined GPS/GLONASS Processing for High Sensitivity Receivers by Mohamed Essam Hassan Roshdy Tamazin A THESIS SUBMITTED TO THE FACULTY OF GRADUATE STUDIES IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE DEPARTMENT OF GEOMATICS ENGINEERING CALGARY, ALBERTA July, 2011 © Mohamed Tamazin 2011 Abstract This thesis presents a comprehensive study on the advantages of using combined processing of the Global Positioning System (GPS) and the Global Navigation Satellite System (GLONASS) for receivers in comparison with a GPS-only receiver in degraded signal environments. Existing commercial High Sensitivity (HS) GPS receivers suffer significant degradations in many environments such as in indoor environments and urban canyons due to restricted visibility of available satellites. Even if a sufficient number of satellites are available, the geometric Dilution of Precision (DOP), the noise and multipath can often be large, leading to large errors in position. Currently there are more than twenty-four active GLONASS satellites in orbit. It is therefore advantageous to concentrate on combining the GPS and GLONASS measurements to achieve more reliable and accurate navigation solutions. In this research, data was collected in an indoor environment and in urban canyons. A software receiver, namely GSNRx™, was used to process the data in both standard and high sensitivity modes. The analysis studies the benefits of combined HS GPS/GLONASS processing in terms of measurement availability, pseudorange degradation, signal power degradation, navigation solution availability, residual analysis, positioning accuracy and DOP.

  • Coordinate Systems in Vision Neurophysiology
    Coordinate Systems in Vision Neurophysiology Marcelo Gattass1 and Ricardo Gattass2 1Tecgraf Institute, Department of Informatic, Pontificial Catolic University of Rio de Janeiro, PUC-Rio, Rio de Janeiro, RJ, 21941-902, Brazil 2Program of Neurobiology, Biophysics Institute Carlos Chagas Filho, Federal University of Rio de Janeiro, Rio de Janeiro, RJ, 21941-902, Brazil 1 Abstract Abstract: Algorithms have been developed to: 1. Compare visual field coor- dinate data, presented in different representation systems; 2. Determine the distance in degrees between any two points in the visual field; 3. Predict new coordinates of a given point in the visual field after the rotation of the head, around axes that pass through the nodal point of the eye. Formulas are proposed for the transformation of Polar coordinates into Zenithal Equatorial coordinates and vice versa; of Polar coordinates into Gnomic Equatorial of double merid- ians and vice versa; and projections of double meridians system into Zenithal Equatorial and vice versa. Using the transformation of polar coordinates into Cartesian coordinates, we can also propose algorithms for rotating the head or the visual field representation system around the dorsoventral, latero-lateral and anteroposterior axes, in the mediolateral, dorsoventral and clockwise directions, respectively. In addition, using the concept of the scalar product in linear alge- bra, we propose new algorithms for calculating the distance between two points and to determine the area of receptive fields in the visual field. 2 INTRODUCTION Coordinates of the visual field are challenged by the same problems that car- tographers have faced to represent points and areas on the earth's surface.
