3D Analysis: Scan Information / Characteristics
The Scan Information Panel that is located on the Right Sidebar provides general information regarding the scan image (e.g. date and time, field length and width) as well as information of each scan value (e.g. position, depth, GPS coordinates).
Figure 1 shows the Scan Information Panel with its toolbar and its three categories of information.
The toolbar of this panel contains following buttons:
Open Google Maps
Push this button to open Google Maps in your webbrowser to indicate the location of the current measurement. This button is only enabled if valid GPS coordinates are attached to the current measurement.
Push this button to edit the characteristics of the current scan image (e.g. field length and width, project title and notes, soil type, etc.). Read subsection Editing Characteristics for further details!
The information categories that are displayed in the Scan Information Panel are:
This category contains information about the date and time when the scan was taken as well as the operating mode that has been used to conduct the current measurement. Additionally it provides the total number of scan values.
This category provides location information like Longitude and Latitude of the current scan value (the value at the crosshairs).
The last category provides all information regarding position and depth of each scan value.
- Impulse ... indicates the distance to the starting point (red axis).
- Scan Line ... indicates the distance to the right side of the scan area (green axis).
- Depth ... indicates the depth of the selected scan value (blue axis). The depth value depends on the selected soil type.
- Scan Value ... indicates the raw value of the measured data. This value is mostly interesting for support issues (and must be enabled in the General Preferences).
The basis of each 3D scan analysis is information. You must provide as much information regarding the measurement as possible. Therefor click either in the Main Toolbar or the toolbar of the Scan Information Panel. The dialog from figure 2 will appear on screen.
In the General category you can enter following information:
Give your project a descriptive name. This title will also appear on any PDF Report that you are going to create.
This text field can be used to add any additional information that might be necessary to be written down (e.g. description of environment or measurement conditions).
Select the proper scan mode that has been used to record the measurement. Especially for older scan files this value must be applied manually.
Enter the length of the scan area to determine correct position information.
Enter the width of the scan area to determine correct position information.
Enter the GPS Latitude of your scan area to mark its position for Google Maps.
Enter the GPS Longitude of your scan area to mark its position for Google Maps.
You can add a photograph of your scan area (preferably from bird's view) and overlay it with your scan image to get a better indication of the position of potential targets within your measurement.
Figure 3 shows an example of that kind of image that has been included in the scan image.
Use the button to open an image from your hard disk and the button to delete the assigned image.
After opening an image you have to adjust the mapping of the image. Move your mouse pointer over the colored squares and while holding the left mouse button down, you move the square to the appropriate corner of the scan area in your image. Only then the image will be mapped correctly on top of your scan image.
The last option you have to adjust are soil types. Figure 4 shows the list of soil types.
Please choose the most relevant soil type from this list to make sure the depth calculation is as precise as possible.
