Note: This table is the most up-to-date list of the errors that FHWA has encountered. If you encounter an error that is not mentioned here or in the Frequently Asked Questions section, please e-mail the Road Inventory Program VisiData Group with questions or additions to the list.

Unfortunately, the VisiData 2.9.8 software interface displays many menu items, buttons, and checkboxes that are not functional for the NPS or FHWA user (including anything relating to DRate, WiseCrax, *.810 files, or *.1S0 files).

Problem Produce the error Expected behavior Actual behavior Solution / workaround Reason for error

VisiData opens, but after some installations, an error message appears saying that the default database file path is not a valid file name. From the main menu, select Tools >Options… and type the file path to the default database (probably C:\Program Files \Roadware \Visidata\Files\ default.mdb) into the Default Database text box. Unknown
Reset video settings window checkboxes Open a workspace whose video paths are not set or which do not access all of the video. Checking or unchecking the four checkboxes in the Reset video settings window should affect the prompting of the video paths. Checking or unchecking the checkboxes does not seem to affect how frequently a user is prompted for the video paths. -- Unknown
Transverse Profile graph From the main menu, select Window >Transverse Profile…. The Transverse Profile window should display the transverse profile of the roadway. he Transverse Profile window displays a blank graph. -- Functionality not enabled for version 2.9.8.

Options window Step Size function From the main menu, select Tools > Options…. In the Options window, in the Step Size text box, type a step size other than 2 mmi. When the video is played, it should skip frames so that the video images displayed are the specified step size apart from one another. Sometimes, the video plays with the requested distance interval between images. Other times, it ends up “off”, or plays the video at an interval that is not the step size that was specified. Skip frames using the Skip scrollbar. If the video is playing according to a step size that was previously entered, but is not the current desired step size, re-start VisiData to revert to the 2 mmi default. Unknown
Options window Offset function From the main menu, select Tools > Options…. In the Options window, in the Offset text box, type an offset other than 0. When pavement video and forward-facing video are played together, the forward-facing video should display before the corresponding pavement image, according to the distance set in the Offset text box. Setting the offset value to a number other than 0 sometimes causes the forward-facing video to display at awkward intervals. -- Unknown

The grid and chart windows should be numbered starting with 0. The windows will appear with a different sequence of numbers that starts with the next highest available number of grid or chart window (i.e., 2 and 3 instead of the expected 0 and 1). Open a different workspace and then re-open the original workspace.  If that does not work, re-start VisiData. Unknown
