Xofia Euro v.3.0

Xofia Euro is a currency converter and calculator that performs operations with many different currency units. You can change the number of displays you want to work with by simply resizing the program window. For each display you can specify a different currency unit. You can configure any number of currencies in the application's currency table. The exchange rates for the configured currencies are updated from the Internet.

TRANSDAT 10.03

The program TRANSDAT executes coordinate transformations with and without changing the geodetic reference system (datum shift) in high quality and with heigh performance. With the program TRANSDAT theese world wide coordinate transformations and Reference System transformations are available: 1. The current and many historical Coordinate and Reference Systems of all States of the European Union (EU) including the eastern extension from April 2004 and other European Systems. 2. The US- and Canadian State Plane- and other Coordinate and Reference Systems of the North American Continent. 3. The Coordinate and Reference Systems of the Australian Continent. 4. A lot of Coordinate and Reference Systems of other Continents. 5. All world-wide used Coordinate and Reference Systems. Apart from the given world-wide and state-specific systems also your own coordinate systems and geodetic reference systems can be defined with Helmert or Molodenski (Bursa / Wolf) parameters. You find a complete list of the coordinate and reference systems supported by the program after downloading the temporally limited test version from the adress http://www.killetsoft.de/transden.htm in the file "readme.doc" or directly at the adress http://www.killetsoft.de/transdpe.htm#liste. The program is appropriate for the keyboard input of coordinates and for the treatment of coordinate files in the Text, dBase, ArcShape and ArcGenerate format (with Shape Viewer). All actions are stored in a log file. Self installing Network ability, usage as DLL in own applications and batch processing is possible. A programmable GPS interface receives satellite coordinates for subsequent treatment in the program. English and German language program design and handbook.

SEVENPAR 1.01

Purpose of the program SEVENPAR is to produce a set with seven Helmert transformation parameters valid for an specific area, with which then arbitrary points of the area can be transformed from one coordinate system into another with high accuracy. The Helmert transformation parameters are computed with a set of individual identical points. Those are points with known coordinates in both coordinate systems. For the computation at least three identical points must be present. In practice you will be anxious to use more identical points than those three necessities. Cartesian coordinates or geographical coordinates with ellipsoidal height using the ellipsoid dimensions are suitable. Identical measuring points of higher order can be usually inquired or referred by the official institutions for measurement. The necessary ellipsoid half-axis are available in the program for the selection from lists. There are altogether to determine seven parameters, i.e. three translations, three rotations and a scale constant. The parameters are calculated by the compensation according to the method of the smallest squares (L2 norm, Helmert transformation). Therefore must be dissolved a formula system with seven equations and seven unknown quantities. The coordinates of the identical points are tested intensively on outliers and deviations by different statistic procedures. The quality of the computed seven Helmert parameters is documented by a cleavage matrix and by the computation of the middle, maximum and root mean square (RMS) deviations. The seven Helmert parameters are calculated in the three most usual standards. Those are the Coordinate Frame Rotation, the Position Vector Transformation and the European Standard ISO 19111.

WinDate Calculator v.2.4

WinDate Calculator is a flexible utility program that allows you to quickly perform date calculations without having to manually thumb thru a calendar. It can work with any dates between Sept. 14, 1752 and Dec. 31, 3999. Features include the ability to define count criteria, mark recurring holidays, perform calculations by days/weeks/months/years, copy/paste dates in a variety of formats, and optionally sit in the Windows system tray.
