3. If a different mix calibration will be used, press the Calibrate button and open

the appropriate max calibration. Skip this step to use the mix calibration that was

originally used when recording data.

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

plotting the data.

5. Select File, Open, and then the file to replay.

6. When prompted, tell the program to use either the original mix calibration that was

recorded with the data or the currently selected max calibration.

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

users can generate reports and maps as desired.

4.4 Generating Maps and Reports

After a survey has been conducted, reports and maps 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.

• Two different types of map files can be generated by pressing the map icon: a

Google Maps HTML and a Google Maps KMZ. The KMZ file can be opened by

Google Earth and the HTML file can be opened by any web browser. The HTML

file can be sent (emailed) to any smart phone for viewing in the field. Select the

appropriate image (density or temperature) and then the desired map file type

(HTML or KMZ). An example is shown in Figure 8.
