4.4 Replaying Data

The ESS Concrete Scanner allows replaying data so that plots can be re-examined and

new reports can be generated. To replay data, follow the instructions below.

1. Insure that the scanner unit and odometer are switched off.

2. Start the data acquisition program by touching and holding the

EssGpr4LoggingApp icon on the desktop. Select the Pavement Condition tab.

3. Press the button and input the desired grid layout that will be used when re-

plotting the data.

4. Select File, Open, and then the file to replay. Repeat as necessary to replay

multiple lines.

5. The data will replay over the course of a few minutes. When the replay is finished,

users can generate reports and maps as desired.

4.5 Generating Maps and Reports

After a survey has been conducted, reports can be generated.

• To save an image of the either the pavement density map or the pavement

temperature map, press the icon. Select the appropriate image (density or

temperature) and then the desired image file type (PNG, BMP, or JPG).

• Two types of reports can be generated. The first is a PDF file that contains the job

information metadata, the calibration information, the measured pavement density

statistics, and finally images of the pavement density map and pavement

temperature map. The second is a CSV file that contains the job information

metadata, the calibration information, and the measured pavement density

measurements. The CSV file can be imported by other software packages (i.e. a

spreadsheet) for further analysis and plots. Press the button and select the

desired report type and file name.

4.6 Advanced Data Processing, Depth Slices, and 3D Views

The EssGpr4LoggingApp does not have the capabilities to generate depth slices or 3D

views of the subsurface. To generate these views, use the companion program

ESSentialUnderground that is distributed with the system.

4.7 Charging the Batteries

There are three rechargeable batteries in the system that provide sufficient power for

operation over a full day. The battery in the scanner unit provides power for about 5 hours. A

second battery is provided so that surveying can continue after the first is depleted.

Additionally, the Microsoft Surface Pro 4 tablet contains a battery that will provide 5-8 hours of

continuous operation depending on screen brightness settings. The shipping container contains

an integrated battery charger that can simultaneously charge all of the batteries with only a

single external power connection. The system is designed to be charged overnight so that all of

the batteries are ready for use during the work day. To charge the batteries, follow these steps.
