The coordinate system on a PDF page is called User Space. This is a flat 2- dimensional space, just like a piece of paper. And in fact that’s a good way to think about it. The units of User Space are called “points” and there are 72 points/inch. The origin, or 0,0 point is located in the bottom left hand corner of the page.
• Polar-Rectangular conversions where coordinates of points in polar coordinates, say bearings and distances, are converted to rectangular coordinates. • Two-Dimensional (2D) transformations where the coordinates of points in one rectangular system (x,y) are transformed into coordinates in another rectangular system (X,Y).
A geographic datum transformation is a calculation used to convert between two geographic coordinate systems to ensure that data is properly aligned. Geographic coordinate systems describe how locations on the earth are placed on a hypothetical reference spheroid. They use angular units, such as degrees, to assign locations to coordinates on a
Geoscience Australia provides a range of web applications, documents and spreadsheets to help with coordinate transformations, conversions and ellipsoid computations. The documents and spreadsheets are a reference standard. They can be used for computations of small datasets and as a validation source for software development.

To simply change the datum – not the coordinate values , select Correcting the Geographic Coordinate System – do not reproject the data. To move the data to the new GCS, select Reproject the data to the new Geographic Coordinate System. WARNING: This will change the coordinates of the data to the corresponding coordinates in the new system.
PDF Coordinate System PDF documents have the following properties: The origin of the document is at the bottom-left corner. The x-axis extends to the right and the y-axis extends upward. All locations and sizes are stored as logical values in PDF units. One PDF unit is equivalent to a DTP point (1/72″). PDF documents do not have a resolution. Conversion between Cylindrical and Cartesian Coordinates The rectangular coordinates (x, y, z) and the cylindrical coordinates (r, θ, z) of a point are related as follows: These equations are used to convert from cylindrical coordinates to rectangular coordinates. x = rcosθ y = rsinθ z = z

used in finite-element computer programs. Here we focus on the coordinate transformations required to convert the differential equations, originally expressed in Cartesian coordinate systems into other systems. Notation for different coordinate systems The general analysis of coordinate transformations usually starts with the equations in a
