Handling the Software

Introduction

Task of the software is to mix files from reconstructions at different locations in one file.

Conditions

The files are available in ghk file format, which means that besides the data there are coordinate information about the measuring location and the measuring parameters saved at it.

Working Principle

1. The coordinates of the data are analyzed with respect to their position and a result room is put up which can receive the entire data. If the spatial discretization of the files is different, the smallest discretization is used for the result space. This can make the file big, of course. It is possible to set the expansion of the result space manually.

2. The file’s coordinates can be corrected by an offset parameter, an automatic progression with a similar distance is.

3. From the software version 11.2018 on it must be distinguished whether the data is only described by a local coordinate system or by a local and a global coordinate system (see below). (In the software the data is distinguished as regular data and as single handling data.)

3a) Data described only by local coordinate system:

1. The data is added to the result space, which means date from different measurements are superimposed. The data are added into the result room, which means that data from different measurements are in superposition. This is useful, because there will be an improvement of the focus in the overlapping area.

2. The result of the superposition is displayed interactively on the screen and can be applied to the whole file series after checking the parameters. Interactive means that single files can be switched on and off and can be moved. The area of the superposition’s result of every selected files are marked by a red border.

3. For the treatment of vectorial recorded data, the results can be merged into two separated result rooms. The data rooms are called as ‘channels’ and can be represented in a single image in one color space (e.g. channel 1 in red and channel 2 in green). It is possible to store the merged results in ghk files with channels.

4. The result image merged from every files and channels are shown without transparency. This is only set, when an additional background image is activated.

5. When data of the same type are shown simultaneously, then all regular data are summarized and plotted as so called single handling data.

3b) Data described by local and global coordinate system:

1. Files with information about the global coordinate system are marked in the file table with a star (*) in front of the file name.

2. The files are not added into the result area but are shown as single files separately. Data of different files can graphically overlap and are together visible with a transparency. The transparency mode is automatically active at more than one file and is set by a floating value beside the option button. In contrast to this, the data area without global extended information are shown only transparent, when the option Image for the background image is activated in addition.

3. Files can be assigned to different channels. These channels stay separated from each other and are mixed at the graphic output, at first.

4. In order to show the superposition of colored channels in transparency mode, the background color can be can be chosen (Settings -> Axis Background Color). In this case black should be the chosen color.

5. To test, or because of other reasons, the global coordinate system settings of the files can be ignored (Settings -> Ignore Global Coordinates). Then the data are handled, as if the global shifts are not existing (look up a)).
