GpsView

Draw GPS/IMU residuals for all photo orientation data

This program displays the residuals of GPS and IMU data.

Getting started​

After starting GpsView, a file-selection window opens.

Select the following file:

  • GPS/IMU residual file. The default filename is gpsresi.dat.

To distinguish flight lines, include LINE statements in the GPS/IMU data files. Small gray dashes then indicate the ends of the flight lines.

While the file-selection window is open, changing the project directory in BINGO Manager affects this application.

To reset the filename, select Settings > Set File Defaults.

To reset all graphics parameters, select Settings > Set Drawing Defaults.

Click Draw to open the graphics window and close the file-selection window. To return to the file-selection window, select File > File Selection.

After you click Draw, the program checks whether the selected file exists. If it does, the program reads all data from it.

If an error occurs while reading the file, the GpsView window remains open so that you can select another file. Click Draw to create the graphics window.

Properties of the graphics window​

Adjust the settings in the graphics window as needed. Drag any edge or corner to resize the window.

To zoom in and out use the mouse wheel or the scale bar at the right side. Hold the left mouse button down to pan the zoomed graphics; as soon as the button is released, the graphics will be redrawn and the shift becomes visible.

The output is color-coded. The max values show the maximum residual size for positions in 1/1000 ground units (if 1/1000 is selected) and for angles in mgon.

When you move the cursor over an image symbol, the upper-left corner of the window shows the line ID, the selected shift and drift parameter key (if any), the image ID, and the GPS or IMU residuals for that image.

Right-click a photo symbol to copy its photo ID to the BINGO Manager message window. You can then select it with the mouse and press Ctrl+C to copy it to the clipboard.

Save and print graphics​

The GIF File button opens a window for copying the current screen graphics to the clipboard or saving them to a file in the project directory. The output format can be GIF (Graphics Interchange Format) or PNG (Portable Network Graphics). GIF files have the smallest size; PNG files are larger but provide better colors. The selected format is saved in the INI file.

Without opening this window, press Ctrl+C to copy the graphics to the clipboard or Ctrl+S to save them to a file.

If the last two characters of the filename are digits (for example, GpsView_Graph_00), the number is incremented automatically. This prevents existing files from being overwritten. Other filenames have no protection against overwriting.

Press Ctrl+V to paste the graphics from the clipboard into Windows applications such as Microsoft Photo Editor, Word, PowerPoint, Outlook, Paint, Adobe Photoshop, or IrfanView.

The free IrfanView application provides a convenient printing interface for creating paper copies of the drawings. Printouts from large screens provide acceptable resolution up to DIN A2.
