Asset Tagger

Asset Tagger was created to facilitate asset collection, and is designed to be used in conjunction with ScanLook VV. Its purpose is to allow the user to navigate(play/pause/seek) the video and Google Maps trajectory that is currently loaded in ScanlookVV, tag/save an asset along with its meta data, then repeat the process. When done, the user can save the asset collection to an XML file and optionally export a KML/KMZ file for use in Google Earth.

The Workflow

  1. Open desired project in ScanLookVV
  2. Click View→Map in ScanLookVV to bring up the Map
  3. Start Asset Tagger
  4. 1If required, Click File→Open Chainage File to load the desired chainage file
  5. 1Optionally, Click File→Open Asset File to open previously saved asset file
  6. 1If required, Click File→Open Config File to open the desired config file
  7. Navigation:
    1. In ScanLookVV, Click a spot on the blue route in the Google Map to seek to that position on the route. Asset Tagger will update accordingly
    2. To jump to a chain Id: Type a chain Id (of the format A+BB, example: 8+00) into box to the right of the Goto Chain button, then press the button to jump to that chain id.
    3. To jump to a coordinate: Type Easting and Northing coordinates into the X and Y boxes, then press the Goto XY button
  8. Use the Play/Pause/Stop buttons to to stop the video and trajectory when you find an asset to collect
  9. To collect an asset (example: Pavement deformity)
    1. If required, you can press the Set START Chain button to save the current chainage coordinates, this will mark the beginning of the asset
    2. If required, you can play/seek forward to advance the video/trajectory slightly
    3. If required, you can press the Set STOP Chain button to save the current chainage coordinates, this will mark the ending of an asset
    4. Fill out the TOD, SOD, WOD, and LOD boxes
      1. When filling out the length of deformity box (LOD), you may press the Use Start/Stop Chain button. Doing so will set the length to the distance between the StartChain and StopChain values saved in steps 9a and 9c above
    5. Press the Save Asset button. The asset is now saved.
    6. If needed, you may now seek to any position necessary and press the Save Image button to save an image to the asset that you just created. You can navigate to any position and then press the Save Image button any number of times to save any number of images to the asset saved in step 9e above.
      1. The image files are saved to the same folder as the currently loaded asset file, with a timestamped filename of the following format: YYMMDD-HHMMSS.jpg

1There are settings available to auto-load the last used Chainage, Asset, and Config files under the Options menu. When these settings are in use, those files are loaded automatically when Asset Tagger is started, without the need to use File→Open […] File.

Config Files

Config files allow you to make your own lists/relationships for the TOD and SOD boxes. Each TOD item can have a corresponding list of SOD items that populate the SOD box when the parent TOD item is selected. The format for config files are as follows:


For example, the following is the default config.txt file that ships with asset tagger:

Longitudinal Cracking,<2mm,2-5mm,>5mm
Traverse Cracking,<2mm,2-5mm,>5mm
Block Cracking,<2mm,2-5mm,>5mm
Crocodile Cracking,<2mm,2-5mm,>5mm
Edge Break,20-75mm,75-200mm,>200mm
Patches,Crack Repair,Block Repair,Hole Repair,Repair
Surface Texture,Ravelling,Stripping,Flushing
Pavement Saturation
Pavement Deformation
Pavement Scouring
Pavement Loss
Formation Deformation
Formation Scouring
Table Drains Sediment Blockage
Table Drains Scouring

You can create your own config files by using the above described format. Simply save it as a text file, and load it in Asset Tagger by clicking File→Load Config File. The TOD/SOD boxes will then be populated with the items in the config file for use.
