PATM:The worldwide leading program for block adjustment using the most economic and well-proven method of independent models for the adjustment with efficient and automatic alternation of horizontal and vertical iteration steps. Developed and continuously upgraded due to the improvement of photogrammetric theory and the progress in new computer systems since 1970, the program is used successfully by more than 500 companies and institutions for daily practical work. Highly optimized with regard to extreme numbers of observations and models, PATM shows stunning execution speed on Personal Computer systems. The end line version PATM-NT is about 3 times faster than the DOS version using the same computer. |
Features:The calculation of all required initial values of the unknowns is done automatically from your data, without referring to preceding manual preparation. There are no restrictions concerning overlap, numbering systems, number of observations and block size. Automatic correction of earth curvature and refraction can be applied optionally. Automatic detection and elimination of blunders during the adjustment avoids tedious manual data cleaning. The used method of robust estimators for data cleaning guaranties detection of all possible data errors ranging from administrative numbering errors up to small measuring errors in the critical range of error detection. Besides the adjustment of photogrammetric observations from independent models and control points, the program includes optional simultaneous adjustment of height information from shoreline points of lakes or sea and observations from APR and statoscope to reduce the number of necessary height control points. The optional simultaneous adjustment of kinematic GPS observations with automatic linear drift correction in all three co-ordinates guaranties high absolute accuracy for economic adjustment projects with minimum number of control points. |
Applications:PATM is well suited for all topographic mapping projects. Point determination projects and engineering applications are covered as well, particularly at small and medium scale. |
Input and Output:The observations of model co-ordinates will be used directly besides the observations from object space and all a priori standard deviations. All observations can be read in from ASCII files in any user-defined format. Initial orientation parameters, if available, can be read in to reduce the number of iteration steps. All block parameters, information about the iteration steps and statistics of interest will be listed in the printout file. In addition, model connections, corrected and transformed model co-ordinates and residuals; adjusted terrain co-ordinates, critical points and orientation parameters can be selected for printout and / or onto additional ASCII files. |
User Interface:The menu-guided input of data including help function avoids most handling and typing errors and reduces training courses to the photogrammetric essentials. A continuous informative display during execution of the adjustment keeps the user fully informed about the progress of data cleaning and the adjustment. |
